Formstack Sign uses a simple, but powerful application programming interface to make it easy for developers to integrate with our product.


What is an API?

API is an acronym that stands for application programming interface. An API is a method of data transfer that sends data between apps at set intervals. This is similar to how a traditional integration would work.

How do I use Formstack Sign's open API?

We love to work with new organizations to connect Formstack Sign to popular products. Depending on requirements and the complexity of the connection, a new integration can often be ready for beta testing in less than two weeks with minimal effort required from your team.


Why would I use an API?

If Formstack Sign doesn't already integrate with the tool you need, an open API allows you to build the connection yourself. If you're interested in providing customers with safe and secure eSignature collection by integrating your product with Formstack Sign, please take a moment to contact us.
