I didn’t try with Postman. I already connected some other calls successfully to this API, but for this call it seems the “application/json” doesn’t work.
Doesn’t look like you need a linked data+json content-type though. With the ld+json I’d expect to see an @symbol prefixing at least on of the json body keys.
Foreal, if I can’t get an api call to go thru in bubble in the first few tries, I resort to postman (or hopscotch.io) as it seems to give me a better picture of what’s going wrong.
What body are you using in postman? If you are sending something sucessfully, can you try the same hardcoded call in the API connector in bubble. then try it with dynamic data
