eSignatures.io API

eSignatures.io API - Welcome!

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"}]}'

Curl send contract

Basics - REST API, JSON data, Token authentication

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"}'

This request creates the contract and sends the links (via email or SMS) to the signers to collect their signatures.

Parameter Description
template_id Specifies the template to be used for the contract (the template_id is shown when editing the template)
title The unique title of the contract (Template name when not specified). It appears in emails, generated documents, and on dashboard pages
metadata Custom information
locale Setting the signer page/emails language. Currently available locales: da nl it pt sl cz pl hu es hr en-GB en no ro ja fr vi sv de rs id sk
test The sent contract is marked as 'demonstration only', and no fee is deducted for sending the contract.
custom_webhook_url The Custom webhook URL to be used for the webhook notifications, instead of the default one specified on your API page
signers List of signers
signers:name Name of the signer
signers:email Email address of the signer
signers:mobile Mobile number of the signer (Non-US mobile numbers must start with the country code, eg +61)
signers:company_name Company name for the signer
signers:signing_order A number that defines the order of signers. When the same number is used for two or more signers they will receive the signature request at the same time. By default the signers will receive the signature requests in order (not at the same time).
signers:auto_sign When yes, the signer's signature will automatically be added to the contract. Please note that this feature can only be used to add your own electronic signature record to the document, and it can't be used to Auto-sign on behalf of your clients/3rd parties.
signers:signature_request_delivery_method The preferred method to deliver the initial request to the signer. The available options are 'email', 'sms', 'embedded', '' and by the default the value is calculated.
signers:signed_document_delivery_method The preferred method to deliver the signed document to the signer. The available options are 'email', 'sms', '' and by default the value is calculated. Note: Delivery of the signed document is a legal requirement in most countries. If the signed_document_delivery_method is disabled then you will need to deliver the documents to the signers.
signers:required_identification_methods Ensures that the signer's contact details get verified via secret links or 6 digit verification codes. This parameter is automatically set, when not specified. The required_identification_methods list can include email and/or sms, or none of them. Adding multiple methods will result in 2Factor identification. You can switch off any verification by providing an empty list [], but note that sufficient signer identification is a legal requirement in most jurisdictions.
signers:redirect_url The signer will be redirected to that URL after signing the contract.
signers:embedded_redirect_iframe_only When the signing page is embedded within an iframe, setting this flag to yes prevents redirecting the entire page.
placeholder_fields Placeholder fields are the highlighted texts in the template between curly brackets, eg {{interest_rate}}. Replace the Placeholder fields with simple custom text using the placeholder_fields:value parameter, or with headers, paragraphs using the placeholder_fields:document_elements parameter.
placeholder_fields:api_key The "api_key" is the text between the curly brackets in the contract templates. Eg: {{interest_rate}}

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/assets/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:

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

Optional:

Advanced Placeholder fields
