Common integration questions
Why am I getting an authentication error?
Confirm the APPAUTHKEY and APPSECRET belong to the same application, are copied without extra spaces, and are being sent with every request.
What should I check when an endpoint returns no data?
Verify the date range, merchant identifier, pagination values, and any required filters before retrying the request.
How should failed API requests be retried?
Use a short retry delay for temporary errors, avoid repeating invalid requests, and log the full response code for later review.
Where can I find request and response examples?
Open Documentation for endpoint details, sample payloads, required headers, and example responses for each module.
Guidance
Troubleshooting API issues
1. Validate credentials
Check that the app is active, the merchant account is enabled, and the correct keys are being used for the environment.
2. Inspect request format
Confirm headers, content type, JSON structure, required fields, and timestamp or timezone values before sending the request.
3. Review response codes
Use the status code and message to separate validation issues from permission, rate limit, or temporary server errors.
4. Share useful details
When contacting support, include the endpoint, request time, response code, and a sanitized payload sample.
Typical response time: under 24 hours, Monday - Friday.
