Overview

The following response headers will be returned for all API calls made against the Partner RESTful API interface. Response headers specific to a given use-case - such as the X-Total-Count header relevant for dynamic querying of a list valued resource - are listed under the reference for the specific endpoints to which they are applicable.

📘

The X-Correlation-ID and Date headers are especially important for our troubleshooting - so we strongly recommend recording these headers, along with the request URL (and request body if applicable) in your application logs for every API request
