Update Rules

Important Update Considerations

  • Only provide fields that need to be updated
  • Nested objects (like billing_address) must be updated as a complete object
  • Empty strings ("") will clear the field value
  • Null values are ignored
  • Phone numbers must be in E.164 format
  • Email addresses must be valid format

​
Rate Limits

Customer update requests are limited to:

  • 10 requests per minute per API key
  • 1000 requests per day per API key

​
Versioning

The current version of this API is v1. We recommend including a version accept header:

Accept: application/json;version=1

​
Best Practices

  1. Partial Updates

    • Only send fields that need to be changed
    • Use PATCH for partial updates
    • Validate data before sending

  2. Error Handling

    • Implement proper error handling
    • Validate response status codes
    • Log failed update attempts

  3. Idempotency

    • Use idempotency keys for critical updates
    • Retry failed requests with the same idempotency key

  4. Validation

    • Validate all input fields client-side
    • Handle validation errors appropriately
    • Check response data matches expected format
