• Modern platforms handle 1,000 to 100,000+ recipients without architectural changes, processing over 1M payments daily
• Automated compliance features eliminate manual KYC, OFAC screening, and W-9 collection—significantly reducing administrative time
• Real-time webhooks enable bidirectional data sync with CRM systems for instant settlement tracking
• Talli's platform drives up to 30% higher redemption rates compared to paper checks

What Is a Class Action Settlement Disbursement API?

A class action disbursement API automates the distribution of settlement funds to potentially millions of claimants through digital payment rails, replacing manual paper check processes. These platforms integrate with existing case management and CRM systems to handle everything from claimant verification to multi-channel payment distribution across 300+ payment methods in 190+ countries.

At its core, a disbursement API provides RESTful endpoints that connect your legal tech stack to payment infrastructure. Unlike standard payment gateways designed for e-commerce transactions, settlement disbursement APIs include specialized features for legal compliance:

• Automated identity verification through KYC/AML screening
• Sanctions screening via OFAC database checks
• Tax compliance with W-9 collection and 1099 generation
• Qualified Settlement Fund (QSF) support for dedicated account structures
• Audit trail generation meeting federal court reporting standards
• Fund segregation preserving legal compliance throughout disbursement lifecycle

How Disbursement APIs Differ from Standard Payment Gateways

Standard payment processors focus on merchant transactions with instant authorization and settlement. Disbursement APIs operate in reverse—distributing funds from a central pool to numerous recipients rather than collecting payments from customers.

The architectural difference creates unique technical requirements. While payment gateways prioritize fraud prevention on incoming transactions, disbursement APIs emphasize compliance automation and recipient verification. The platforms must handle complex workflows where claims administrators approve payments, claimants verify identities, tax documents generate automatically, and multiple payment rails activate based on recipient preferences.

Why API Integration Matters for Large-Scale Class Action Settlements

Manual processing becomes mathematically impossible at scale. A settlement with 100,000 claimants requiring individual payment verification, bank account validation, and tax documentation would consume thousands of staff hours. The largest settlements involving millions of claimants cannot function without automation.

API integration delivers measurable efficiency gains across the settlement lifecycle:

• Speed improvement: Processing time drops from weeks to days, with some platforms enabling near same-day distribution for eligible payment methods
• Cost reduction: Digital transaction fees average significantly less than paper check costs
• Compliance automation: Built-in KYC, OFAC, and W-9 workflows eliminate manual verification bottlenecks
• Real-time visibility: Stakeholders monitor completion rates and fund flows through live dashboards
• Reduced unclaimed funds: Digital options with automated reminders decrease abandonment compared to undeliverable checks

Manual Processing Bottlenecks in High-Volume Settlements

Traditional check-based distribution creates cascading inefficiencies. Address verification alone becomes a massive undertaking when up to 30% of checks may never reach recipients due to outdated contact information. Each returned check triggers manual research, address updates, and reissuance—costing an estimated $150 per check in tracking and reconciliation.

Fraud detection remains nearly impossible with paper methods. Digital platforms use device fingerprinting and duplicate claim flagging to block fraudulent attempts before processing, protecting settlement funds from abuse.

Pre-Integration Requirements: Authentication and Access Credentials

Before writing a single line of code, establish proper authentication infrastructure. Modern disbursement platforms use OAuth 2.0 bearer tokens or API key authentication to secure connections.

Your technical setup checklist includes:

• Sandbox environment access for testing without financial risk
• Production API credentials with appropriate permission scopes
• IP whitelisting configuration restricting access to authorized servers
• Rate limiting documentation to prevent accidental service disruption
• Webhook endpoint URLs for receiving real-time transaction events

Sandbox environments provide isolated testing spaces where you can process test claims through the full workflow without affecting real settlement funds. Production credentials carry real financial consequences. Implement security best practices including secret rotation schedules, environment variable storage, access logging, and role-based permissions.

Core API Endpoints for Class Action Settlement Workflows

Disbursement APIs organize endpoints around settlement lifecycle stages. Understanding the complete workflow helps you architect efficient integrations.

Campaign Creation and Configuration Endpoints

Settlement campaigns begin with initialization calls that establish payment parameters:

• POST /campaigns: Create new settlement with metadata (case name, court jurisdiction, total fund amount)
• PATCH /campaigns/{id}/settings: Configure payment methods, verification requirements, deadline dates
• POST /campaigns/{id}/fund: Initiate fund transfer to segregated settlement account
• GET /campaigns/{id}/status: Monitor campaign state and fund availability

Each campaign operates independently with dedicated accounting, enabling firms to manage multiple settlements concurrently without cross-contamination risk.

Claimant Data Submission and Validation Endpoints

After campaign setup, submit claimant rosters through bulk or individual endpoints:

• POST /campaigns/{id}/claimants/bulk: Upload CSV files with claimant details (name, contact, payment amount, unique ID)
• POST /campaigns/{id}/claimants: Add individual claimant records programmatically
• GET /claimants/{id}: Retrieve claimant status, verification results, payment history
• PATCH /claimants/{id}: Update contact information or payment amounts before distribution

Platforms validate submissions in real-time, flagging missing required fields, duplicate entries, or data format errors. This immediate feedback prevents downstream processing failures.

Payout Initiation and Status Tracking Endpoints

Payment execution requires explicit approval workflows protecting against accidental fund releases:

• POST /payouts/initiate: Trigger payment processing for approved claimants
• GET /payouts/{id}/status: Check individual payout state (pending, processing, completed, failed)
• POST /payouts/{id}/cancel: Halt in-progress payments before settlement
• GET /campaigns/{id}/analytics: Retrieve aggregate metrics on completion rates

Status endpoints return structured JSON responses with timestamps, payment method details, and failure reasons enabling automated retry logic.

Integrating KYC, OFAC, and W-9 Collection via API

Compliance automation represents the most valuable aspect of API integration. Manual identity verification and sanctions screening consume massive resources while introducing human error risk.

Automated Identity Verification Workflows

Modern platforms embed KYC verification directly into the claim submission process. When claimants access their secure payment link via SMS or email, they encounter multi-step verification:

• Personal information confirmation: Name, address, date of birth matching claim records
• Government ID upload: Driver's license or passport photo capture with automated validation
• Selfie verification: Liveness detection preventing photo substitution fraud
• Device fingerprinting: IP address and browser metadata flagging suspicious access patterns

API endpoints expose verification status through GET /claimants/{id}/verification, returning detailed results including confidence scores and specific failures. This enables your system to route borderline cases to manual review queues while auto-approving clear matches.

Tax Compliance Document Collection

Payments exceeding $600 trigger 1099 reporting requirements. Disbursement APIs automate W-9 collection through embedded web forms within the claimant experience:

• IRS TIN validation: Real-time verification against IRS databases preventing incorrect taxpayer identification numbers
• Digital signature capture: Legally binding W-9 attestation without paper forms
• Automated 1099 generation: End-of-year tax forms produced automatically with IRS filing
• Document storage: Encrypted archival meeting OFAC compliance and audit requirements

The POST /claimants/{id}/tax-documents endpoint accepts W-9 data programmatically, while GET /campaigns/{id}/tax-forms retrieves year-end 1099 batches for IRS submission and claimant distribution.

Implementing Multiple Payout Methods Through a Single API

Claimant payment preferences vary dramatically by demographics. Supporting diverse methods maximizes redemption rates while accommodating individual circumstances.

Supporting Bank Transfers and Digital Wallets

Direct deposit via ACH transfers provides the most cost-effective distribution method with zero fees to claimants. Your API integration should collect bank routing and account numbers through secure forms, then pass this data to POST /payouts/each endpoint with encryption.

Many platforms support popular digital wallets, such as:

• PayPal/Venmo: Instant transfers to email-linked accounts (fees may apply)
• Cash App: Popular among younger demographics, settling within minutes
• Zelle: Bank-to-bank transfers without third-party accounts
• International methods: Wise, Payoneer for cross-border settlements

API endpoints support dynamic payment method selection through GET /payment-methods, returning available options based on claimant location and campaign configuration.

Prepaid Card and Gift Card Distribution Options

For unbanked populations, prepaid cards provide instant access without requiring existing financial relationships. The Easy Prepaid Mastercard is issued by Patriot Bank, N.A., Member FDIC, pursuant to a license from Mastercard International.

Gift card distribution serves smaller settlement amounts efficiently. Gift Cards are issued by InComm and distributed by Talli. The gift cards are redeemable at participating merchants as specified in the accompanying terms and conditions. This method works particularly well for settlements under $100 where bank transfer setup friction exceeds payment value.

Configure payout method priority through POST /campaigns/{id}/payment-rules, establishing fallback sequences when primary methods fail.

Real-Time Webhook Configuration for Settlement Tracking

Webhooks transform your integration from polling-based to event-driven architecture. Rather than repeatedly checking payment status through GET requests, the disbursement platform pushes updates to your systems as transactions progress.

Setting Up Webhook Listeners in Your Stack

Webhook implementation requires exposing HTTPS endpoints on your infrastructure:

• POST /webhooks/payment-completed: Receives confirmation when funds settle to claimant accounts
• POST /webhooks/payment-failed: Alerts to failed transactions with detailed error codes
• POST /webhooks/verification-completed: Notifies when KYC/OFAC checks finish
• POST /webhooks/document-submitted: Triggers when claimants upload required documentation

Register these endpoints through the platform's POST /webhook-subscriptions API, specifying event types and delivery URLs. Most platforms support signature verification through HMAC tokens, enabling your system to validate authentic webhook sources versus spoofed requests.

Handling Webhook Retries and Failures

Network reliability isn't guaranteed. Robust implementations include:

• Idempotency keys: Prevent duplicate processing when webhooks retry
• Exponential backoff: Platforms retry failed deliveries at increasing intervals
• Dead letter queues: Store persistently failed webhooks for manual investigation
• Status reconciliation: Periodic GET /payouts/{id}/status polling catches missed webhook events

Your webhook handlers should respond with HTTP 200 status codes within 5 seconds to prevent timeout retries, deferring heavy processing to asynchronous background jobs.

Syncing Settlement Data with Legal Case Management Software

Isolated payment systems create reconciliation nightmares. Bidirectional integration between disbursement APIs and case management platforms enables real-time visibility for attorneys, paralegals, and court administrators.

Connecting Disbursement APIs to Clio and Other Legal Platforms

While Clio doesn’t offer a native integration with specialized settlement disbursement platforms like Talli, REST API capabilities on both platforms enable custom integration. Map disbursement data to Clio matter records through:

• Matter linking: Associate settlement campaigns with Clio matter IDs via custom fields
• Activity logging: Post payment status updates to matter activity streams
• Document attachment: Upload 1099 forms, payment confirmations to Clio document management
• Time entry automation: Generate billing entries when administrators review flagged payments

This integration requires middleware—either custom code or iPaaS platforms capable of translating between API formats, enabling non-technical teams to manage these connections.

Automating Case File Updates with Settlement Status

Real-time data synchronization eliminates manual status tracking. As claimants complete verification, submit documentation, and receive payments, these events automatically update case management records:

• Claimant verification: KYC completion triggers contact record updates
• Payment distribution: Successful payouts mark claims as "paid" in case tracking
• Failed payments: Bounced transactions create follow-up tasks for case managers
• Completion reporting: Campaign closure generates final accounting summaries for court filing

Configure synchronization rules through the disbursement platform's webhook subscriptions, specifying which events trigger CRM updates and mapping field relationships between systems.

Managing Unclaimed Funds and Abandoned Settlements via API

Despite digital convenience, some claimants never complete the redemption process. Unclaimed settlement funds create legal and financial complications requiring systematic management.

Automated Reminder Workflows to Reduce Abandonment

Proactive communication dramatically improves completion rates. Disbursement APIs enable multi-channel reminder sequences:

• Initial notification: SMS + email with secure claim link
• Day 3 reminder: First follow-up for non-responders
• Day 7 reminder: Second follow-up with urgency messaging
• Day 14 reminder: Final notice before deadline
• Phone outreach: High-value claims triggering manual contact attempts

Configure reminder schedules through POST /campaigns/{id}/notification-rules endpoints, specifying message templates, delivery channels, and timing intervals. Platforms track engagement metrics—email opens, link clicks, SMS delivery—helping optimize communication strategies.

Escheatment Compliance and Fund Return Processes

State escheatment laws require unclaimed funds transfer to government custody after statutory hold periods. Disbursement APIs track these obligations automatically:

• Deadline monitoring: GET /campaigns/{id}/escheatment-schedule returns upcoming state-specific deadlines
• Dormancy flagging: Claimants inactive beyond threshold periods marked for escheatment processing
• Report generation: Automated state-specific unclaimed property reports meeting filing requirements
• Fund transfer: API-initiated payments to state treasury departments with proper documentation

For settlements avoiding escheatment complexity, campaign rules can specify fund return to the settlement administrator or cy pres distribution to charitable organizations after defined periods.

Fund Segregation and QSF Compliance in API Architecture

Qualified Settlement Funds under IRC Section 468B require dedicated account structures preventing commingling with general business funds. API integrations must support these legal requirements while maintaining operational efficiency.

API Support for Dedicated Settlement Accounts

Modern platforms provide virtual account architecture where each settlement maintains separate accounting despite sharing underlying payment infrastructure:

• Campaign-specific balances: GET /campaigns/{id}/balance returns available funds for individual settlements
• Fund transfer isolation: Deposits and disbursements tracked separately per campaign
• Reconciliation reporting: Detailed transaction histories meeting court audit requirements
• Interest allocation: Earnings distributed proportionally to settlement balances

Banking services provided by Patriot Bank, N.A., Member FDIC, ensure regulatory compliance while API abstraction layers simplify technical implementation.

Maintaining QSF Ownership Through API Transactions

QSF compliance requires preserving settlement administrator control over fund distribution. API authentication and authorization models enforce this structure:

• Multi-signature approvals: Large payments requiring multiple authorized party confirmations
• Spending limits: Per-transaction caps preventing unauthorized fund depletion
• Audit logs: Immutable records of all API calls, user identities, and transaction details
• Role-based access: Separate permissions for fund transfer, payment initiation, reporting access

These controls satisfy court oversight requirements while enabling efficient settlement administration operations.

Testing and Validating Your Settlement API Integration

Production failures in settlement distribution create legal liability and reputational damage. Comprehensive testing before go-live prevents these risks through systematic validation.

Running Sandbox Campaigns Before Production Launch

Sandbox environments enable complete end-to-end testing without financial consequences:

• Create test campaigns mirroring production settlement structures
• Upload sample claimant data representing edge cases (special characters, international addresses, high-value payments)
• Simulate verification workflows testing KYC pass/fail scenarios
• Process test payments validating webhook delivery and status tracking
• Generate compliance reports confirming output formats meet court requirements

Document test results systematically, creating runbooks for identified issues and their resolutions.

Load Testing for High-Volume Settlement Distributions

API performance under load determines whether your integration handles mass payout volumes. Simulate production conditions through:

• Concurrent API calls: Test 100+ simultaneous requests measuring response times and error rates
• Bulk upload processing: Submit CSV files with 10,000+ claimant records validating import speeds
• Webhook flood testing: Verify your endpoints handle hundreds of concurrent webhook deliveries
• Database query optimization: Ensure claimant status lookups remain fast as records grow

Modern disbursement platforms handle 1M+ payments daily, but integration bottlenecks on your infrastructure can create failures despite platform capacity.

Monitoring Performance and Completion Rates Post-Integration

Launch is just the beginning. Ongoing monitoring identifies optimization opportunities and prevents small issues from becoming major problems.

Key Metrics to Track in Your Settlement Dashboard

Real-time dashboards should surface critical indicators:

• Completion rate: Percentage of notified claimants who complete verification and receive payment
• Average time-to-payment: Duration from initial contact to fund settlement
• Payment method distribution: Breakdown showing ACH, prepaid card, digital wallet usage
• Verification failure reasons: Categories of KYC/OFAC rejections guiding process improvements
• Support ticket volume: Claimant inquiry rates indicating UX friction points
• Fund reconciliation status: Real-time balance matching between settlement account and distributed payments

These metrics enable proactive intervention. If completion rates drop suddenly, immediate investigation prevents wholesale campaign failures.

Generating Stakeholder Reports from API Data

Court reporting requirements demand comprehensive post-distribution accounting. API endpoints provide raw data while platforms generate formatted reports:

• GET /campaigns/{id}/reports/distribution: Detailed payment logs with claimant identities, amounts, dates
• GET /campaigns/{id}/reports/tax-summary: 1099 issuance records for IRS filing
• GET /campaigns/{id}/reports/unclaimed: List of non-responsive claimants with escheatment deadlines
• GET /campaigns/{id}/reports/compliance: KYC/OFAC screening results and fraud prevention actions

Export these reports in PDF, CSV, or Excel formats suitable for court filing and stakeholder review. Automated generation reduces month-end closing from days to hours.

Frequently Asked Questions

What API endpoints are required for a basic class action settlement integration?

Essential endpoints include campaign creation (POST /campaigns), claimant data submission (POST /campaigns/{id}/claimants/bulk), payout initiation (POST /payouts/initiate), and status tracking (GET /payouts/{id}/status). Most implementations also require webhook subscription endpoints for real-time event notifications and reporting APIs (GET /campaigns/{id}/reports/*) for compliance documentation.

How does an API handle OFAC screening and KYC verification automatically?

Disbursement APIs integrate with third-party identity verification services and government databases to automate compliance checks. When claimants submit information through secure payment links, the platform validates government IDs, performs liveness detection through selfie verification, and screens names against OFAC sanctions lists in real-time. The API returns verification status through GET /claimants/{id}/verification endpoints with detailed confidence scores.

Can settlement disbursement APIs support multiple payout methods simultaneously?

Yes, modern platforms support 300+ payment methods including ACH bank transfers, prepaid cards, digital wallets (PayPal, Venmo, Cash App), and gift cards through a single API integration. Claimants select their preferred method during the claim process, with the platform routing payments through appropriate rails automatically.

What is the typical API response time for processing large-volume settlement payouts?

API request processing typically completes within 200-500 milliseconds for individual operations. Bulk claimant uploads via CSV can process 10,000+ records in under 5 minutes with asynchronous validation. Actual payment settlement varies by method: ACH transfers settle in 1-3 business days, digital wallets settle instantly, and prepaid card activation occurs within minutes of verification completion.

How do webhooks track real-time settlement completion rates?

Webhooks push event notifications to your systems as transactions progress, eliminating polling delays. When claimants complete verification, submit documents, or receive payments, the disbursement platform sends POST requests to your registered webhook endpoints with structured JSON payloads containing event details, timestamps, and claimant identifiers. Your system processes these events to update real-time dashboards showing completion percentages and payment method breakdowns.
