Problem
There is an issue with REST API using CURL
- When running the REST URL using the browser , the JSON response is OK
- When running the REST URL using CURL with PHP, user receives the following error :
{"errorMessages":["The value 'XXX' does not exist for the field 'project'."],"errors":{}}Cause
This error can be thrown when the API call is being made without proper authentication and/or authorization. The Jira REST API does allow anonymous access for some endpoints, so when a call is made without authentication, the system can reply in this manner to avoid leaking details to unauthenticated requests. An authenticated, and authorized user session needs to be created first.
Resolution
Create a session as per Security overview. One way would be to use Basic authentication or use the JSESSIONID in the request header.
