https://api.signicat.com/secure-share/The Secure Share API enables you to securely share files with other people in a programmatic way.
You can choose among different levels of security, ranging from weaker methods, such as One-Time Passwords (OTPs), to stronger methods, like using electronic IDs (eIDs).
This REST API uses the OAuth 2.0 protocol for authorisation. All request and response bodies are formatted in JSON.
Before you can start making requests to this API, you need to learn how to connect to it. To do this, see the Connect to Signicat APIs Quick start guide.
Use the Signicat Audit logs service to see documented evidence of the sequence of activities that have affected a system.
When you make an API call to Signicat and an error occurs, you will receive a response message with an error code.
Use the Signicat Events service to automatically receive information about when something happens in one of our services into your system.
Note: This is often referred to as callback.
