The SignatureAPI connector lets you add electronic signatures to your Power Automate flows.

​
Get a Test API Key

To start with SignatureAPI in Power Automate, you need an API key.

You can get a free test API key to try out SignatureAPI and set up your workflow. Here’s how:

1

Sign Up

Sign up for a free account on SignatureAPI.

2

Get your API key

Get your test API key from the API Key section on the SignatureAPI settings.

Test API keys let you create test envelopes, great for trying out your workflows. Envelopes in test mode:

  • Don’t send emails to recipients, but you can see them in the Email area of your dashboard.
  • Are not legally-binding, so no legal obligations arise during testing.
  • Are free.

​
Create a Connection

Create a connection to SignatureAPI in Power Automate using your test API key:

1

Open a Power Automate flow

In Power Automate, open an existing workflow or start a new one.

2

Add a SignatureAPI action

Add a Create Envelope action from SignatureAPI.

3

Create your connection

Enter any name for this connection (for example SignatureAPI Test) and your test API key.

​
Your first SignatureAPI Flow

Check out our Starter Flow. It is a simple guide on using SignatureAPI actions.

​
Switch to Live Mode

When you are ready to send legally-binding envelopes, set up your payment method and get a live API key. Envelopes in live mode:

  • Send emails to the recipients. You can still view these emails in the Email section of your dashboard.
  • Are legally-binding.
  • Are billed.

We recommend you create a new connection to SignatureAPI with your live API key. You can name it, for example, SignatureAPI Live.
