I'm trying to create a Custom Connector to an API endpoint that requires bearer tokens in the header for authentication.
In my Flow, I use a HTTP action to get a token, store it in a variable, and then pass it to my connector in the Authorization header. However, I always receive an Unauthorized error.
I receive this error when I test the connector on the custom connector test page:

Report{
"status": 400,
"source": "https://power-te-westus-1.azurewebsites.net:443/tokens/msmanaged-na/eum.2Dcreategroup.5F058fd1eee2b36bb6.5Fde5addbef9cce72c/shared-eum.2dcreateg-f412c0af-e8aa-49d6-9d10-76928018c41b/exchange",
"message": "Error from token exchange: Bad authorization token. Could not find identity for access token."
}
However, it succeeds when I use a HTTP action to make a call to the same endpoint as my custom connector. I use the same bearer token in the authorization header.
Is there a way I can get this to work as a Custom Connector?
I found a solution regarding expiring Bearer Tokens using Policies in Custom Connectors. Policies allow to rewrite headers.
how to override the dynamic jwt token in custom connector?
Hi @yashag2255
I'm having difficulty understanding your post. I'm retrieving a token and storing it in a variable. I don't understand how this populates the 'Authorization' parameter in the custom connector. How does get the bearer token?
Thank you this was a huge help!
Hi @Anonymous ,
Please refer to the screenshot below. You don't even have to initialise a variable for the token:
Expression used :
All responses (
Answers (body('HTTP_Request_Name')['result']Replace the 'HTTP_Request_Name' with the name of the action in which you are sending the authentication request.
Hope this Helps!

@Rishan , that looks like a good solution. Sorry to resurrect an old post. I've been able to get to the point where I initialize the bearer token variable , but have been unable to provide it as a value in the Authorization header. Were you able to do that, or does the token go elsewhere in the custom connector that you're using?
Hi @Rishan,
Please take this thread for a reference. You will be able to pass your bearer token to the API successfully by the following steps:
