LinkedIn API "A required parameter \"grant_type\" is missing"

[impactsocialchange]

I am trying to implement “Authorization Code Flow (3-legged OAuth)” into my bubble app and am having difficulty with step 3 in the documentation: LinkedIn 3-Legged OAuth Flow - LinkedIn | Microsoft Learn

From the documentation:

Parameter Description grant_type The value of this field should always be: authorization_code

I have this parameter, but it keeps telling me:

"There was an issue setting up your call.

Raw response for the API Status code 400 {“error”:“invalid_request”,“error_description”:“A required parameter “grant_type” is missing”}"

I have added a screenshot (with client_id and client_secret removed).

I’ve tried numerous attempts and cannot get it to work in bubble. I have gotten it to work in postman, but not in bubble.

Any suggestions would be greatly appreciate!

Try ticking the “Queryst” option on all parameters

Thank you so much! That worked!
