We provide a REST API built on pragmatic RESTful design principles using simple and modern technologies. Our eSignature API uses resource-oriented URLs that leverage the built in features of HTTP. The request and response bodies are JSON encoded. Any standard HTTP client can be used to communicate with our electronic signature API.
Our API is authenticated using HTTP Basic Auth over HTTPS. A user’s API key should be provided as auth credentials:
curl -u YOUR_API_KEY: -F email@example.com https://api.digisigner.com/v1/documents
Every DigiSigner account holder is issued a personal API key and can therefore start working with our eSignature API immediately.
Your personal API key can be found in the settings section of your DigiSigner account.
In the following examples, replace the text YOUR_API_KEY with your API key.
Please note that the initial API mode is TEST. In TEST mode, a watermark is automatically added to all uploaded documents. We will switch you to PROD mode when you purchase one of our DigiSigner API Subscriptions.
Before you can proceed with collecting signatures, you must first upload a document to DigiSigner.
If you are using our PHP, Java or C# client libraries, you can skip this step and begin sending a signature request immediately. Our client libraries will automatically upload a document for you in the background.
