Management API reference

Management API Reference

🚨

Note: the Knock management API only provides access to the resources managed in the Knock dashboard, such as workflows, templates, translations and commits.

All other concepts within the Knock notification engine are accessed through the Knock API, which you use to trigger workflows, identify users, and manage preferences.

The Knock management API provides you with a programmatic way to interact with the resources you create and manage in your Knock dashboard, including workflows, templates, layouts, translations and commits. It's separate from the Knock API and only provides access to a limited subset of resources.

You can use the Knock management API to:

Create, update, and manage your Knock workflows and the notification templates within those workflows.
Create, update and manage your email layouts.
Create and manage the translations used by your notification templates.
Create, update, and manage your partials.
Commit and promote changes between your Knock environments.

Authentication

The management API authenticates with a Bearer authentication mechanism using a service token generated on your account.

Note: environment-level API keys should never be used to authenticate with the management API. To authenticate with the management API, generate a service token.

Errors

Knock uses standard HTTP response codes to indicate the success or failure of your API requests.

2xx success status codes confirm that your request worked as expected.
4xx error status codes indicate an error caused by incorrect or missing request information (e.g. providing an incorrect API key).
5xx error status codes indicate a Knock server error.

Postman

You can use our Management API Postman collection to quickly get started testing our Management API.

Workflows

To define a logical flow of your notifications, you create a workflow consisting of workflow steps. Workflow steps can be functions or channels, and can have conditional logic that determines whether to execute that step when the workflow is triggered.

You can retrieve, update, or create a workflow as well as list all workflows in a given environment. Workflows are identified by their unique workflow key.
