Hi JP,
Thank you for speedy response, the provided link was very helpful, it did put us on right track.
I have another question regarding the configuration of inbound webhook. Currently the URL we set in Postmark server configuration gives HTTP 401 error during the test. At the same time we are able to access the server page (methos, description, etc.) via the same URL in browser. We can also contact sercice from our test application sending sample serialized JSON to it.
Is there anything special about configuring inbound webhook URL at Postmark server?
