I am currently running into an issue with my code where I have to send JSON to post an API, but when I send JSON it always says it is receiving text.

You might need to add a content-type header like in the screenshot here: [Cannot set API header for Content-Type](https://community.thunkable.com/t/cannot-set-api-header-for-content-type/2460425)

I had a similar issue with another API. The fix was to add ‘Content-Type’ and ‘accept’ headers to the call, with the text of both set to ‘application/json’.

Can you see an example successful call on the API website for example? It’ll show you what the various elements of a successful call are.
