Error messaging

Error messaging in Image API helps you understand why a read, create, or update request is denied. Expedia Group recommends a robust retry strategy when resolving errors. Details about self-testing will be provided by your Integration Specialist.

Connectivity errors

Connectivity errors may occur when communication disruption occurs between Expedia Group and your software.

If the problem is:

  • Connection timeout (before establishing connection)
  • Cannot resolve host name
  • Cannot establish connection

Before looking for assistance, you should:

  1. Verify the URL used to connect to the API and make sure the address starts with https://.
  2. Verify the domain name, and make sure that the address you are using is the right one for the environment you are targeting. Do not try to send QA information to production, or vice-versa.
  3. If the partner's system is behind a firewall, make sure that port 443 is opened for connection to Expedia's production environment.
  4. Retry. If additional assistance is required, contact us.

The API will leverage HTTP status codes as defined by RFC 2616, Section 10. Users should expect HTTP status codes from the API as indicated in the table below.
