Webhook URL not accepted

[GBulleri]

Hi,

I opened a ticket at the official support but still no answers!

May be that the commnunity can help me!!

When, from my developer account, I write a valid URL into the webhook target URL field, after clicking SAVE Hubspot raises an error inviting me to contact tech support:

"Something went wrong when saving you changes". I tried many times and in different days.

May be an SSL issue?

Thank you

@GBulleri ,

I think the underscore is the issue.  You will also need to have SSL for that url.

You could do a quick test removing the underscore and see if  that is accepted. 

Ideally, you will be able to update that underscore to a dash for your app

Hi,

thank you for you answer.

I just finished now and I explain to the community what happened:

The webhook listener was a webservice (ASMX): I realized that an ASMX webservice cannot accept

json arrays  because the .NET dictionary raises a fatal error.

A  not-array payload is working fine!!...but HubSpot send arrays.....

I replaced the ASMX with a Powershell script and now everything is working fine: just completing the test

Thank You

Hi,

thanks to you suggestion I was able to go ahead with the webhook development.

My webhook is now working but it is raising error 500;  If I run it by postman everything is fine (please look at the attached image)

Can you help me to understand why I see error 500?
