Error 401 'Invalid Credentials'

Hi All,

I have been banging my head the past couple of days and I hope someone can help me with this. I am currently trying to POST to a 3rd party app. Their documentation and support is extremely limited.

I was able to successfully do a POST via Postman, but when I try doing the exact same thing within the API Connector I get Invalid credentials. When I pass the authorization parameters in the Header I get status 400 Bad Request in both postman and bubble. But if I pass the authorization parameters within the Parameters, I get success 200 in Postman and Error 401 “Invalid Credentials!” in the API Connector.

The API authorization in the API Connector is set to “None, self-handled”, so not sure what else to do.

Any help would be appreciated!

Can you share settings in postman? API doc if available too

@Jici
Had to block the api credentials but otherwise here is everything:

General API Info

API documentation on the specific POST request

Whats in Postman that gives me 200 Success


Additional API documentation on the credentials I need to pass to authenticate the request. I just noticed that the credentials needs to be URL encoded if I pass it as parameters (which I do). I am not sure what I need to do here.


Activate querystring or move your parameters to the url. If you look correctly at the postman settings, theses fields are querystring (parameters in the url)
