An API key is a unique token that authenticates form submissions from your website. Add it as a hidden access_key field in your HTML form. When someone submits the form, EdgeSubmit verifies the key and delivers the submission to your configured email.

Yes! Each key has an allowed origins field that accepts multiple domains (comma-separated). All submissions from those domains will be delivered to the same email address tied to that key.

Each API key delivers to one email address. If you need submissions from different sites going to different inboxes, you'll need a separate key for each. This requires the Pro plan or higher, which supports multiple keys.

Regenerating replaces your current key with a brand new one. Your old key stops working immediately. You'll need to update the access_key in all your forms. This is useful if your key is compromised or you want to rotate it for security.

Allowed origins are the website URLs where your form lives (e.g., https://mysite.com). EdgeSubmit will only accept submissions that come from these domains, preventing unauthorized use of your key. When you sign up, your website URL is automatically set as the allowed origin.

Submissions are emailed to the delivery email configured for each API key. You can view and change your delivery email in the Settings tab.

Yes. Go to Settings → Delivery and click the Edit button next to your current delivery email. Enter a new email and click Save. Changes take effect immediately for all future submissions.
