I’m setting up and testing custom webhooks inside automations for the purpose of integrating with some 3rd party systems — lead distribution, conditional S2S postbacks, etc.
For this, I’m using custom parameters along with AC personalization tags in the webhook URL as a means to push the data in a more convenient and flexible way compared to parsing that data from the contact form data / custom field formats that are sent with the webhook.
e.g.
?contact_ID=%SUBSCRIBERID%&fName=%FIRSTNAME%&email_status=%EMAIL_VALIDATION_RESULT%&src=automation_hook
But! Since today/yesterday it’s no longer possible to save the webhook URL with pers. tags as it returns an invalid URL warning.
The catch is, I was in touch with AC support for another related issue (account-level webhooks), and there was no mention of support for pers. tags in webhook URLs being removed. 
Was this change intentional, or there’s some issue?
Hi Aidy,
Phil from ActiveCampaign here. Thanks for reaching out, hope you had a great weekend!
I just looked into this and did some testing on my end. Fortunately, it looks like we still support adding URL queries to webhook URLs inside automations: Zight 2024-07-29 at 2.46.45 PM.
I noticed while I was testing that if you do not include “https://” in your URL, it will not allow you to save the URL and will give the “invalid URL” error: Zight 2024-07-29 at 2.57.37 PM
Would you please try to set up the webhook step again, making sure to include the “https://”, and see if it allows you to save the webhook? If not, please follow up with me here, including a screenshot of the error as well as the full URL you’re using (can be shared in a private DM or in ticket format), so that I can take another look.
I’m hopeful that this gets you back in good shape, and please don’t hesitate to reach out with any updates or questions. Have a great rest of your day ahead!
