Introduction

The Task History API allows you to query your users’ usage of integration workflows and access data from historical workflow executions.

Task History API is available for Paragon customers on Enterprise plans. To learn more, contact your Customer Success Manager or [email protected].

​
When to use the Task History API

The Task History API can be used to analyze integration usage or pull information about historical workflow executions into your application. For example, you can use the Task History API to:

  • Query the number of workflow executions that ran last week for the Salesforce integration

  • Query all failed workflow executions for a specific user

  • Export all tasks that occurred in a specific month into Google BigQuery

You can find example queries in the request format below.

​
Generating API Keys

The Task History API authorizes with a project-level API Key, instead of the Paragon User Token.

API Keys provide access to all Connected Users in the project they are created in and can be rotated or deleted after being generated.

To generate a new project-level API Key:

  1. Visit your Project’s Settings > API Keys.

  2. Click “Create API Key”. Provide a meaningful name for the API Key for your reference.

  3. The API Key will appear on a one-time basis for you to save in a secure place.
