Looking for more control over how your documents are delivered and signed?
If you’re using the Signable API, Embedded Signing lets you take the reins.
Instead of sending documents through Signable emails, Embedded Signing gives you direct access to the signing page – so you can deliver it however you like. 
No more relying on inboxes or third-party email visibility. Just a seamless signing experience built right into your own workflows.
What Could This Look Like for You?
Here’s how teams are already using Embedded Signing to streamline signing and boost engagement:
Email the signing link directly from your own domain
Why?
More control over delivery (avoid “unknown sender” issues)
Use dynamic templates tailored to different document types
Stay on-brand with your own email designs and tone
Send the link via SMS
Why?
Reach people where they live – their phones!
Improve open and sign rates across all demographics
Perfect for quick turnarounds or mobile-first users
Embed the signing page in your app or portal
Why?
Seamless user experience across your platform
Trigger signing as part of existing workflows
Add your own security layers like 2FA or login verification
What You’ll Need to Get Started
To unlock Embedded Signing for your account:
-
Be on a paid monthly or annual Signable plan
-
Sign our acknowledgement form (just message Support and we’ll send it over!)
-
Contact us to enable Embedded Signing for your account
-
Do some engineering work to integrate with our API (see below)
Now for the Technical Stuff…
Once Embedded Signing is enabled on your account, here’s what your devs will need to do:
Integrate with the Signable API - find our documentation here!
Your backend system will need to call our API – at a minimum:
POST https://api.signable.co.uk/v1/envelopes
to create and send envelopes.
Set up two webhooks - you’ll find both in our API docs.
-
send-envelope
-
signed-envelope
Putting It All Together
When an envelope is sent, the send-envelope webhook will send a payload to your chosen URL.
This payload includes an envelope_signing_embed field – and that’s your magic link to the signing page.
From here, you can:
-
Embed it in your app or portal
-
Send it via SMS
-
Email it with your own design
-
Automate it however you like
