Tipalti is a leading global payables automation platform that streamlines the entire payment process, from onboarding suppliers to tax compliance and mass payouts. This DIY Developer Guide for Tipalti offers a structured, scalable, and secure approach for building custom integrations with ERP systems, CRM platforms, financial reporting tools, and eCommerce platforms.

Prerequisites for Tipalti Integrations

• Tipalti Admin Access and API Credentials (API Key, Client ID, Client Secret)
• Familiarity with:
  • RESTful APIs
  • OAuth 2.0 Authentication
  • JSON or XML data formatting
• Tools: Postman, Tipalti API Documentation, SDKs (Node.js, Python)

Step 1: Authentication for Tipalti Integrations

Tipalti APIs use OAuth 2.0 for secure authentication.

OAuth 2.0 Authentication Example:

POST https://api.tipalti.com/oauth2/token
Content-Type: application/x-www-form-urlencoded

grant_type=client_credentials
&client_id=YOUR_CLIENT_ID
&client_secret=YOUR_CLIENT_SECRET

Use the returned access_token for all API requests.

Step 2: Endpoint Discovery and Data Mapping

Common API Resources:

• Payees (Vendors)
• Payments
• Invoices
• Payment Reconciliation
• Tax Forms (W-9, W-8)

Process:

• Review Tipalti API documentation.
• Map internal fields (e.g., vendor ID, invoice ID, payment status) to Tipalti objects.

Important considerations:

• Managing vendor onboarding and KYC verification
• Handling mass payments and payment status updates
• Tax document collection and validation

Step 3: Building Integration Workflows

Integration Patterns:

• Inbound (to Tipalti): Push vendor onboarding data, submit invoices, initiate payments.
• Outbound (from Tipalti): Retrieve payment statuses, reconciliations, and tax compliance reports.

Example: Creating a New Payee

POST /api/Payees
{
  "payeeName": "Acme Suppliers",
  "email": "finance@acmesuppliers.com",
  "paymentMethod": "ACH"
}

Example: Fetching Payment Statuses

GET /api/Payments
Authorization: Bearer YOUR_ACCESS_TOKEN

Step 4: Error Handling and Pagination

Error Handling:

• Capture Tipalti-specific error codes and standard HTTP responses.
• Implement retry logic for transient 5xx errors and 429 (rate limit) errors.

Pagination:

• Use limit and offset parameters for retrieving large datasets.

Example:

GET /api/Invoices?limit=100&offset=100

Step 5: Testing and Validation

• Use Tipalti Sandbox Environment for testing.
• Validate payee creation, invoice submission, payment processing, and tax compliance flows.
• Conduct load testing for high-volume payment processing scenarios.

Step 6: Deployment and Security

• Deploy integrations securely on cloud platforms (AWS, Azure, GCP).
• Store API keys and tokens securely using secret management systems.
• Enforce HTTPS/TLS encryption for all communications.
• Set up proactive monitoring, real-time logging, and alerting for failures.

Step 7: Maintenance and Monitoring

• Monitor Tipalti API release notes for updates and changes.
• Set alerts for failed payment submissions, rejected invoices, or expiring OAuth tokens.
• Track KPIs like vendor onboarding completion rates, payment success rates, and reconciliation accuracy.

Optional Enhancements

• Middleware integration (MuleSoft, Celigo, Boomi) for expanded workflow automation
• Webhooks for real-time notifications on payment status changes and payee updates
• Custom dashboards for monitoring payables and financial performance metrics

Summary

Building custom Tipalti integrations helps organizations automate complex global payables processes, ensuring faster vendor onboarding, accurate mass payments, and streamlined tax compliance. This DIY Developer Guide for Tipalti offers a secure, scalable, and proven framework for creating high-performance finance automation integrations.
