Authorization Bearer in Header - Custom Connector

(3) Share

Report

Posted on by Community Power Pla...

I have created a custom connector that is connecting to a vendor's API. I have unauthenticated GET methods working, but now am working on some POSTs and am running into an issue with putting "Authorization: Bearer token_value" in the header. Even on the unauthenticated GET calls, I can see in the request header that "Authorization: Bearer some_token_value" is already there. I've tried setting the Header in my POST call, but then I get the error: "Message": "Error from ASE: Bad authorization header scheme".

I can see that the request header has my token_value and so it appears I'm not allowed to set the header that way. What is the right way to send my "Authorization: Bearer token_value" to the API?

Thank you.

I ended up opening a ticket with Microsoft, went back and forth with them a few times, but they never seemed to understand the issue no matter how many times I explained it, so I've had to give up for now.

I've figured this out by learning about making an OpenAPI document describing the interface, and creating a custom connector off of the document.
On the Security tab, select "API Key" for the Authentication type
For "Parameter Label" put whatever you want someone to see when they are creating a Connection off of this Connector...I used "API Key"
"Parameter Name" should be "Authorization" (no quotes)
For "Parameter Location", select "Header"
When you create a Connection off of this Connector, you'll be prompted for your "API Key" (or whatever you used for step 2 above)
Enter "Bearer YOUR_BEARER_TOKEN_VALUE" (no quotes)
This will pass your bearer token to the API successfully.

Nice, I will try this. However, this doesn't work with an expiring token.

This did not work for me. Actually nothing has to this point. I've tried encoded Basic authentication with api key and bearer token but still get 401 unauthroized.

This works for me as the admin-developer. However when sharing the app with end users, it forces them to enter the API Key to use the application.

Is it known if there is a way to work-around this functionality?

The solution provided by rpiwetz worked for me, sort of. I did need to add an "accept:application/json" header to the defenition first though, otherwise I got a 401 error.

I said "sort of" above because I still cannot figure out a solution for an expiring token. I can get this to work by population the connector with my expiring token, but then it only works for 1 hour. Has anybody figured out a solution for an expiring token?
