I have a custom plugin, with an API with oauth2 user-agent flow authentication method.
This API has a data call, which successfully retrieves data when I click “initialize call” button in the plugin editor.
However, when I add an element to the page that uses this API’s result as data, the endpoint isn’t getting called. This happens for both authenticated and unauthenticated users.
The moment I turn off authentication or switch to private key in header/URL, the data API endpoint gets called.
The behaviour is slighlty different if I use API connector plugin instead.
Here the API end does get called, but only when a user is logged in, whereas with custom plugin, the fact that user is logged makes no difference.
