Failed to load resource: the server responded with a status of 404 ()

Hi there,

I’d like to use Contact Form 7 on a website where I pass a GET parameter, but then the form does not submit. It looks like Contact Form 7 is building the wrong URL, adding a path AFTER the question mark, like so:

https://[SITE]/wp-json/?%5BPARAMETER%5D=%5BVALUE%5D/contact-form-7/v1/contact-forms/517/feedback

A similar issue may have been reported earlier (this one also featured GET parameters):

(I have deactivated Contact Form 7 on my site for now but can create a separate page to see the issue if that helps)

Then, if the GET parameters work, I’d like to prefill the whole URL in one of the form fields. So far, I was able to use “default:get” and prefill only the parameter.

Best,

Patrick Mackaaij
