Zendesk API calls are not working properly when using the Zendesk Customer API Action card in Workflows with GET requests. It is possible to experience one of the following conditions:

• Timing out after over 700 seconds.
• Receiving one of the errors:
  • 415 Unsupported Media Type
  • 400 Bad Request​

• Workflows
• Zendesk connection - Custom API card

When creating the relative URL Input for the GET Request with the Custom API Action Card, .json is missing at the end of the URL, and/or the following header is not added: 

"Accept: application/json"

Adding .json to the end of the GET API call will allow the call to work properly (see the cURL example for each method). More details in Zendesk Developers - Groups.

• Example:

  • https://company.zendesk.com/api/v2/groups/3432.json  (working)
  • https://company.zendesk.com/api/v2/groups/3432 (this has an issue)

If the .json is at the end of the URL but a 400 Bad Request is the response received, then make sure to have the header added in the Custom API Action card:

"Accept: application/json"

• NOTE: Requirement from Zendesk API Documentation: "You must set an Accept: application/json header on all requests"
