Integrating Mailchimp with Webflow

I am trying to integrate Mailchimp with Webflow but when I enter an email it says “Oops, something went wrong while submitting the form”. I have followed the Youtube video on how to integrate Mailchimp with Webflow several times to make sure I didnt miss anything but with out any luck. I also went through several forums but that did also not help me resolve my problem. Can anyone help me?

Any help is appreciated!

@gabbe18 - the most common issue I see with this is either the post action not going to the correct url in the form settings or the field name not being aligned with what Mailchimp is expecting:

I’m seeing a 404 on the post to mailchimp, which makes me think your endpoint url is incorrect:

I see thank you. How do I fix that?
