Pay REST API Overview
Versioning
All API calls should be made with a CBPAY-VERSION header which guarantees that your call is using the correct API version. Version is passed in as a date (UTC) of the implementation in YYYY-MM-DD format. New versions maintain backwards compatibility. The current version is 2023-10-01.
Authentication
Authenticated API requests should be made with headers, CBPAY-APP-ID and CBPAY-API-KEY. If authentication fails, a JSON object with an error message is returned with HTTP status 401.
Your app ID and API key are provided at onboarding.
If you integrated before API keys were issued during onboarding and want to use this API, contact us and we can provide you with your API key.
Rate Limiting
The Buy Quote API is rate limited to prevent abuse that would degrade our ability to maintain consistent API performance for all users. Throttling is enforced per endpoint by app ID at 100 requests per second. If your requests are being rate limited, HTTP response code 429 is returned with a rate_limit_exceeded error. Rate limiting is implemented using a sliding window algorithm.
Contact us to request a rate limit increase.
