I have created a rest connector for DHL. I was able to get the token correctly. But when trying to execute a post call. The below error occurs. I am passing the token to the Authorization in the format Bearer format

Hi,

Are you sure you pass the token correctly? Next step would be to look in att the REST connector log file to make sure you have the correct header as described in the DHL API Doc . If that doesn’t give any clues I always setup the same request(s) in Postman, it’s just easier there to troubleshoot.

Great!

Could you also share the Request? And it would be helpful to see the Postman request that works as well. 🙂

The Rest connector can produce two files per Request. One for Request and one for the Response. Can you post the content of the Request log file? That should also include headers etc.

Thx. I suspect you don’t have the same values for the Authorization header in Postman and Flow. Is it in factt empty?

And why are you using both an Authorization header and the custom “DHL-API-Key” header with an API key?

I would open the Console in Postman to see the RAW request and compare it to what’s printed in the Flow log. And make sure that you have the same Token for auth in Flow as you do in Postman.

And if you have in fact posted an API key here, I suggest you create new one since it’s kind of compromised 🙂

Ohh yeah, I see it now. Good catch, great that you solved it! Bit confusing with the response there, should have said “Resource not found” or something 🙂
