}📖 Step-by-Step Guide
Step 1: 🔑 Set Up Security Keys
Generate your private and public key pair and share your public key with Finserve. See the Security & Signatures Documentation (opens in a new tab) for detailed instructions.
Step 2: 🎫 Authenticate
Obtain an access token using the authentication endpoint. See the Authentication API documentation (opens in a new tab) for details.
Step 3: 📋 Prepare Transaction Details
Gather all required information:
countryCode, accountNumber, accountFullNameStep 4: ✍️ Generate Signature
Create the signature string by concatenating in this exact order:
countryCode+accountNumber+accountFullNameSign this string using your private key, then Base64 encode the result.
Step 5: 📝 Set Up Headers
Include the following headers in your request:
Content-Type: application/jsonAuthorization: Bearer [your_access_token]Signature: [your_base64_encoded_signature]
Step 6: 🔧 Construct Request Body
Create a JSON object with all required fields following the structure shown in the example request.
Step 7: 🚀 Send POST Request
Make a POST request to the internal bank transfer endpoint with your headers and body.

Best Practices
-
** Security**
- Store your private key securely and never expose it in client-side code or version control
- Always use HTTPS for API requests
- Store access tokens securely
- Regenerate signatures for each request
-
** Signature Generation**
- Ensure exact string concatenation order:
countryCode+accountNumber+accountFullName - Do not include spaces, separators, or special characters in the concatenated string
- Always Base64 encode the signature before including it in headers
- Verify the values in the signature match exactly with the request body values
- Ensure exact string concatenation order:
-
** Transaction Reference**
- Use unique reference numbers for each transaction
- Implement a reference generation system to avoid duplicates
- Store reference numbers for reconciliation and audit purposes
- Never reuse reference numbers, even for failed transactions
-
Amount Formatting
- Always use decimal format with two decimal places (e.g., "500.00")
- Pass amounts as strings, not numbers
- Ensure the amount is positive and within allowed limits
- Verify amount matches exactly in signature and request body
-
Error Handling
- Implement retry logic with exponential backoff for transient errors
- Log transaction attempts and responses for audit purposes
- Handle signature validation errors by regenerating the signature
-
Testing
- Always test with the UAT endpoint before using the live endpoint
- Use test account numbers provided in the documentation
- Verify signature generation with sample data first
- Test error scenarios to ensure proper handling
-
Data Validation
- Validate all account numbers match the expected format
- Verify country codes are valid and supported
- Ensure transfer dates are in the correct format (YYYY-MM-DD)
- Validate currency codes match the destination country
Troubleshooting
Invalid Signature Error (403)
If you receive a 403 error with "Invalid signature":
- Verify the concatenation order:
countryCode+accountNumber+accountFullName - Ensure no spaces or separators are included in the concatenated string
- Check that the signature is Base64 encoded
- Verify your public key is correctly registered with us
- Ensure the values in the signature match exactly with the request body values
Common Signature Mistakes
- Using wrong concatenation order
- Adding spaces or separators between values
- Not Base64 encoding the final signature
- Values in signature don't match request body values
