Trello Webhooks into ServiceNow

[Chris Pike]

Hi,

I'm new to the Trello APIs and I'm trying to create a webhook with a callback URL to my ServiceNow instance.

I can use Postman to send a POST request to my callback URL and I get a status of 200 and all is good. However if I put my callback URL into a POSY request for creating a Trello Webhook it fails with "URL mycallbackurl.com.au did not return 200 status code, got 405"

Is there something that needs to be configured in ServiceNow response? I'm at a loss at the moment and seem to be going round in circles.

Many thanks,

Chris

Hey Chris,

I spoke with the team about this, and it does look like something may be up with the ServiceNow configuration. The endpoint you use should return 200 when we run our HEAD request. Here is a little excerpt on that from our Trello Webhook Docs:

"The provided callback URL must be a valid URL during the creation of the webhook. We run a quick HTTP HEAD request on the URL, and if a 200 status code is not returned in the response, then the webhook will not be created. Additionally, if your callbackURL contains an invalid SSL certificate the webhook will not be created (no SSL certificate will not cause the creation to fail)."

I'd suggest reaching out to ServiceNow about the configuration. Here is their contact page: https://www.servicenow.com/support/contact-support.html

I hope this helps, let me know if you have any other questions or concerns!
