Hello André,
Yes this is possible, you even have two possibilities.
You can add the header “Authorization”
The value can be one of two types, Basic or Bearer.
Basic is username password like this:
Basic base64("<username>:<password>")
Which would become this for example:
Basic base64(edo:password)
Which once you encode the value becomes this as the value of the Authorization header:
Basic RWRvOkh1bnRlcjI=
The Bearer type is this:
Bearer <bearer_token>
That token is the token you can get via an oauth login processaction.
it can also be a PAT (Personal Acess Token).
With kind regards,
Edo Spijker
