eSignatures.io API

Quickstart - Send yourself test a contract

Replace the apitest@esignatures.io to yours:

curl -X POST -H 'Content-type:application/json' 'https://esignatures.io/api/contracts?token=c21bc7' -d '{"template_id": "20ac76c9","signers":[{"name":"Sam Signer","email":"apitest@esignatures.io"}]}'

Basics - REST API, Token auth, Rate limiting

POST https://esignatures.io/api/contracts HTTP/1.1

curl -X POST -H 'Content-type:application/json' 'https://esignatures.io/api/<action>?token=your-secret-token'

The API calls are organized around REST with JSON data. The authentication as based on a token parameter in the URL. You can find your Secret token on your API page after logging in to your eSignatures.io account. Please note that requests from browsers will result in CORS error, in order to safeguard your secret token.

Rate limiting: To protect against accidental requests and intentional attacks, our service uses an adaptive rate limiting technique. Adaptive rate limiting means that the rate limiting changes based on the usage patterns. Please note that it's discouraged to repetitively 'poll' contract information via the API, eg GET /api/contracts/<id>. Using Webhook notifications is the recommended way to keep your contract statuses updated.

Parameter	Description
token	Your API secret token

Contracts

Contracts can be fully managed via the API. Sending a contract can be done with a single API call, and after that signatures are collected, and notifications are provided at every stage of the contract’s lifecycle via webhooks.

Send a contract

POST /api/contracts HTTP/1.1

Example request

curl -X POST -H 'Content-type:application/json' 'https://esignatures.io/api/contracts?token=your-secret-token' -d '{"template_id": "4templ44-6666","signers":[{"name":"Sam Signer","email":"sam@tenants.com","mobile":"+12481234567"}],"placeholder_fields":[{"api_key":"preferred_term","value":"24 months"}], "test": "yes"}'

Webhooks

Use webhooks to be notified about events that happen real-time. For example, when a contract gets signed, a request is triggered to the Webhook URL specified by you on the API dashboard page. Creating a webhoook endpoint on your server means simply accepting POST requests at a given URL. Webhook data is sent as JSON in the POST request body.

If a webhook is not successfully received (not 2xx response code), eSignatures.io will continue trying to send the webhook once an hour for up to six times. The requests timeout is 5 seconds.

All Webhook requests we trigger use BASIC auth. You can enforce or ignore that. The username is your API secret token, without password.

Embedded signing

Iframe code

<iframe src="SIGN_PAGE_URL">
</iframe>

Iframe code with auto-resize

<script src="https://code.jquery.com/jquery-3.4.1.min.js"></script>
<script src="https://cdncf.esignatures.io/staticassets/iframeResizer.4.2.10.min.js"></script>
<iframe
    src="SIGN_PAGE_URL"
    id="eSignaturesIOIframe"
    onload="iFrameResize({heightCalculationMethod: 'bodyScroll'}, '#eSignaturesIOIframe')"
    style="width: 1px;min-width: 100%;">
</iframe>

Example POST#contracts request to create the contract

curl -X POST -H 'Content-type:application/json' 'https://esignatures.io/api/contracts?token=your-secret-token' -d '{"template_id": "4templ44-6666","signers":[{"name":"Sam Signer","email":"sam@tenants.com","signature_request_delivery_method":"embedded"}]}'

The sign page can be embedded into an iframe. Steps:

Create a contract with POST#contracts, and specify signature_request_delivery_method=embedded for the signer.
The response json will include a data:contract:signers:sign_page_url for that signer.
In the 'iframe code' (see example), replace the SIGN_PAGE_URL with the sign_page_url.

Optional:

Specify the redirect_url when creating a contract, and the signers will be redirected to that URL after signing the docuemnt.
Set the required_identification_methods to [] to skip the identification process. Note: it is a legal requirement to identify the signers. If the required_identification_methods is [] you will need to identify the signer via email, SMS or other means to form legally binding contracts.
Set the embedded_redirect_iframe_only to yes to prevent the entire page being redirected. Only the iframe will load the redirect page when set to yes.
