Would like to connect to API using client_credentials grant type.
Is 'client_credentials' grant type supported for LogicApp / flow connector?
Connector builder converts this to "flow": "accessCode" which will make it

grant_type=authorization_code

security defn in swagger file is as follows.

 "securityDefinitions": {
 "oauth2_auth": {
 "flow": "application",
 "scopes": {
 "file.*": "file.*",
 "integration.*": "integration.*"
 },
 "tokenUrl": "https://example.com/token",
 "type": "oauth2"
 }
 },

Re: Custom connector to connect to API using client_credentials grant type

Hi @msj , I am wondering if you have found any solution to this?

I am trying to consume an on-premise API using "On Premise data Gateway" and "Custom Logic App Connector" but it seems it does not support client_credentials grant type

I tried below approach too but failed:
Approach: Get Oauth Token separately by calling the onPremise token URL and then make actual API call with token in Authorization header.
Approach result: "Custom Logic App connector" does not allow to define "Authorization" key in header
