Signicat Secure Share API (v1)

Download OpenAPI specification:Download

Base URL: https://api.signicat.com/secure-share/
Documentation: See the Secure Share developer documentation.
Support: Create a support ticket in the Signicat Dashboard.

Introduction

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.

Get started

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.

Audit logs

Use the Signicat Audit logs service to see documented evidence of the sequence of activities that have affected a system.

Access it: Signicat Dashboard > Settings > Audit logs
For information generic to all Signicat audit logs, see the general Audit logs documentation.

Errors

When you make an API call to Signicat and an error occurs, you will receive a response message with an error code.

For errors generic to all Signicat APIs, see the general Error codes documentation.

Events (callback)

Use the Signicat Events service to automatically receive information about when something happens in one of our services into your system.

Access it: Go to Signicat Dashboard > Settings > Events
For information generic to all Signicat events, see the general Events documentation.

Note: This is often referred to as callback.
