1. Sign up at firma.dev and grab your workspace API key from Settings > API Keys (use the TEST key while building). 2. Install this plugin in your app and paste the key into the plugin's Authorization field in the Plugins tab.
3. Use the "Create and Send Signing Request" action, passing a Firma.dev template ID and your signer's name and email.
4. Use "List Signing Requests" or "Get Download Link" to check status, and use "Subscribe Webhook" plus the "Verify Webhook Signature" server-side action from a backend workflow to get notified the moment a document is signed.

Note: this endpoint does not currently expose an idempotency key, so if a request times out and is retried (e.g. by Bubble's own 150s retry behavior), there is a small chance of creating a duplicate signing request.
Check status via List Signing Requests before resending if a call appears to hang.
