Testing webhook in postmark returns error 400

[mathieuser]

When I use the webhook in Postmark, and I test it from there, it returns a 400 error. I have a hard time understanding what's up.

Thanks for your help!

Can you check the /logs/campaign.log file for any clues?

I cleared the logs, hen logged in so a web.log was created, then I sent the request from postmark again, but no campaign.log got created apparently... So I don't think it gets into Craft CMS at all

Hmm so when I send a bounce the campaign.log file is created and it receives it, though still getting the 400 error in Postmark.

Are you running the latest 2.7.0 version of Campaign?

[mathieuser]

I just updated to 2.7.0, but no changes on this regard so it seems!

I've done a test through RequestBin, with the same JSON data as in postmark, and i'm getting this response:

I've done a test through RequestBin, with the same JSON data as in postmark, and i'm getting this response:

That error is to be expected, since the request came from an IP address other than one of Postmark’s designated IPs.

The issue turned out to be that john@example.com is not a valid contact in the system. I changed this behaviour so that a successful response is returned, regardless of whether the contact exists, in bb7cc6b and released in version 2.7.1.
