Custom connector to connect to API using client_credentials grant type

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


security defn in swagger file is as follows. 


  "securityDefinitions": {
    "oauth2_auth": {
      "flow": "application",
      "scopes": {
        "file.*": "file.*",
        "integration.*": "integration.*"
      "tokenUrl": "",
      "type": "oauth2"

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
