HTTP Status Codes


  • Do not to code to specific status code responses as they may change in the future.
  • If coding to status is required for integration, it is recommended to code to status ranges. Fundamentally, 200 value codes are successful, 400 value codes are Seller side errors in request structure, request values/specifics, endpoints, etc… and 500 value codes are ChannelAdvisor side server-based or API related errors.
  • Code multiple retries into the integration for 500 responses. 500 responses may generate at times due to a large variety of factors on the ChannelAdvisor side - retrying the requests at a later time will often result in a non-server side error response (success or seller-side error). However, if the 500 responses persists, please open a support case.
