You should be able to integrate with Formspree using the Webhook feature in our Form component. Simply set the Webhook URL to your Formspree endpoint, and our component will post the form data there.
I haven’t tested this in code, so I can’t guarantee it works out of the box, but in theory, it should.
Alternatively, you can use Webhooks to send form data to a service like Zapier, which connects to a wide range of platforms via plugins. That might give you even more flexibility, depending on your needs.
