Authentication problem with a custom endpoint developed in DD.

[ac-developer23]

Hi,

We are trying to integrate DD with a serverless solution in the Cloud to be able to automate a process that includes the use of DD. For this, we have developed an endpoint in DD that allows us to add a record and perform different checks, through a POST request.

The problem is that when testing from POSTMAN, DD does not allow us to login and authenticate ourselves to later make the call to the endpoint we have created.The problem that appears is the following:

We have tried to authenticate using API Key but it didn not work.Is there something that we are missing? If so, please let us know.

Many thanks in advance.
