Connecting with Allegro- oAuth error

Hello,

I’m trying to connect Make.com with Allegro.

Unfortunately, oAuth authorization always finishes with:

{“message”:“The request failed due to failure of a previous request.”,“code”:“SC424”,“suberrors”:[{“message”:“"Unauthorized"”,“name”:“Error”}]}

What additional parameters should I include in advance settings? Any additional headers?

Authorize URI:
https://allegro.pl.allegrosandbox.pl/auth/oauth/authorize

Token URI:
https://allegro.pl.allegrosandbox.pl/auth/oauth/token

Documentation:
Allegro documentation

Explanation of oAuth method by Allegro

I tried with basic configuration and I think every possible “advanced” according to Allegro’s documentation. Always the same error.



Thank you in advance!
