Embed document signing into web app with JavaScript

1

Document signing form for specified email

First, add the DocuSeal functionality to your webpage by including the script. Copy and paste the following line into the <head> or <body> section of your HTML page:

To integrate a DocuSeal form, add the <docuseal-form> element to your webpage with the necessary attributes specifying the form's unique URL and, optionally, a default email address for the signer:

  • data-src: This attribute specifies the URL of the DocuSeal form that you want to embed. Each template form on DocuSeal has a unique URL with slug key. "Slug" key can be obtained via the /templates API or copied from the template page in the web UI.
  • data-email: This attribute is used to initialize the form for a specified email address for the signer.

Signing forms initialized via template URL and email work only if the template contains a single signing party. For signing forms with multiple parties all signers should be initiated via the API.

</docuseal-form>

Document signing form initiated via API

Prerequisites:

Sign Up and Obtain API Key: Visit DocuSeal API Console to obtain your API key.

Template ID: Identify the template ID you want to use for the form.

POST request to https://api.docuseal.co/submissions. Include the obtained API key in the headers along with the content type ('application/json'). Specify the template_id and submitter details:

  • send_email: set to false to disable automated emails form the platform.
  • email: pass email address of each individual party in the document signing process.
  • role: specifies the designated role of each participant (e.g., 'Director', 'Contractor'). Pass role names defined in the template form.

Upon a successful request, the API will respond with a an array of submitters with slug keys to be used in the embed form.

When utilizing the {{ slug }} within the <docuseal-form> element, ensure that you replace {{ slug }} with the actual key obtained from the DocuSeal API response. This "slug" key acts as a reference point to link the embedded form in your HTML to the specific document or workflow created through the DocuSeal platform.

import axios from "axios";

const API_KEY = 'YOUR_API_KEY';

axios.request({
  method: 'POST',
  url: 'https://api.docuseal.co/submissions',
  headers: {
    'X-Auth-Token': API_KEY,
    'content-type': 'application/json'
  },
  data: {
    template_id: 123,
    send_email: false,
    submitters: [
      {
        email: 'john.doe@example.com',
        role: 'Director'
      },
      {
        email: 'roe.moe@example.com',
        role: 'Contractor'
      }
    ]
  }
}).then((response) => {
  console.log(response.data[0].slug);
});
<script src="https://cdn.docuseal.co/js/form.js"></script>

<docuseal-form
  data-src="https://docuseal.co/s/{{ slug }}">
</docuseal-form>
