About esignature APIs

Make requesting signatures, getting status updates, and managing important documents easier with electronic signature APIs.

What is an esignature API?

An esignature (electronic signature or digital signature) application programming interface (API) is a Representational State Transfer (REST) web service that allows subscribers to securely request signatures online, obtain status updates, and download the completed documents.

How does a digital signature API work?

Electronic signature APIs have endpoints that developers use to make API calls. The developer must have an API key to begin using the service and then the API can be added to an application or website. Digital signatures APIs typically use GET and POST request methods to send and receive information. Responses are returned in JSON format. It is important to note that digital signatures are encrypted. Today, electronic signature APIs are authenticated and binding. Therefore, for this purpose, they are referred to as having the same meaning.

Who is a digital esignature API for?

Digital signature APIs are for developers that want to embed digital signature functionality into their applications using the least bit of code.

Document signing APIs are also for businesses that require a secure and efficient way to obtain signatures on their contracts.

Why is an API for electronic signature important?

Digital signatures use mathematical algorithms to validate digital signatures much in the same way a credit card transaction or an email is authenticated. APIs must follow the same type of protocol.

In addition to providing a secure way to transmit files, sign PDF APIs provide a seamless way to manage multiple documents at once. Businesses are prompted with status updates to remind them of signatures that are due.

What can you expect from a sign PDF API?

Developers can look forward to creating applications with document signing functionality faster. This is because the APIs pass secure transfer protocols so they do not have to code this part manually.

Businesses can expect to free up their time tracking signatures for legal contracts. This is especially helpful for businesses of all sizes. Small businesses with limited staff may find they have more time to work on other projects. And for medium and large-sized businesses, instead of becoming side-tracked with monitoring signatures, they can begin to complete more projects on schedule.

Are there examples of free document signing APIs?
