Webhook Error on Form

Hi there, I’ve started receiving emails notifying me of a webhook error on one of my forms but it’s not clear how to fix the error.

Here’s an example of what I’m getting:

Hey! How are you?

                           “CF7 to Webhook” has a built-in feature
that detects when a webhook fails and notifies you with this automated
email.

???????????????????????????– Form: #10899 – ???? Demo Email Collection
???????????????????????????– Webhook: REDACTED
???????????????????????????– Error: “Webhook returned a error code.”

                           Submited data:

{“first-name”:”REDACTED“,”last-name”:”REDACTED“,”your-email”:”REDACTED“}

                           Response Code:
                           404

                           Response Message:
                           “Not Found”

                           Response Body:
                           “please unsubscribe me!”

                           —

???????????????????????????You’ll receive one notification for each webhook with errors.
???????????????????????????Other webhooks maybe were successful.
