Hello Varun Teja Gurrapu we are not using any integration to pass that value. when we use connected system, It gets the access token from the token request endpoint and passes.

maybe, Just make a try, i'm not sure it works:

1. Create an integration to get the bearer authentication token from the API.

2. Use that token and pass it to headers in the update integration through rule inputs.

Or
