What are “Channel Partners”?

Ticketmaster works with various “channel partners” who deal directly with venues, clients, and promoters to source inventory, often at discounted prices and available for sale exclusively through their own platforms. Ticketmaster provides additional APIs to service their needs and requires specific agreements on usage. Contact Ticketmaster for enabling the following APIs.


Why do I receive “No valid access token found” when calling /oauth/info?

If it appears that from time to time the new /OAuth/info endpoint is giving an error “No valid access token found” check if token being used was expired. Once you have obtained an Access Token, you can use it until the time specified by the expires_in key in the response which is 3600 seconds (1 hour) . After that time, you need to get a new Access Token using the Refresh Token .
