HTTP Action always return error 416

I am having some issues with HTTP Action. 

I tried to access an external API by using HTTP Action and GET request, but it always returns an error message status of 416. 



{"errors":[{"status":"416","title":"Request header error","detail":"Unsupported media type received"}]}



I tried to call this API from Postman and managed to get the data successfully.

Any thoughts? Any help will be greatly appreciated

The (vnd.) specifies to specific vendor type designed API, not many API's support this. This is many used when you want to query a blog site to retrieve blog articles related to a specific user along with some metadata tags like link to the blog.


You can use application/json instead. For information related to differences between application/json and application/vnd.api+json please check the link - Header value: application/vnd.api+json - Stack Overflow



if the information shared helps you, please consider giving a thumbs up 👍 and mark solution as resolved



Thanks for your reply. I did try that one and it still returns the same error message.

Do you know what else can I try to solve this?
