What is supported in Harness IDP

Lists the plugins, git providers, and third-party integrations supported in IDP.

Harness Internal Developer Portal integrates with a number of third-party providers to provide a single pane of glass for developers. This page outlines all the supported integrations, providers, and features available in Harness IDP.

1. Git providers

Harness IDP supports the following Git providers for storing and managing catalog entity YAML definitions and Workflow YAML definitions:

Git Provider	Support Type	Documentation
Harness Code Repository	Default	Learn more
GitHub	Cloud & Enterprise	Cloud | Enterprise
GitLab	Cloud & Self-Hosted	Learn more
Bitbucket	Cloud & Server	Learn more
Azure Repos	Cloud	Learn more

AUTHENTICATION TYPE

Backstage does not support SSH auth type for integrations. Only HTTP connection is supported for all Git provider-based connectors in IDP.

API calls in IDP are used to fetch YAML data, last commit SHA, and detect any new changes. SSH authentication cannot be used for making these API calls; it is only used for cloning repositories. Therefore, the main Git connector for IDP Git integration must support API requests, hence HTTP is the only supported method.

4. Harness IDP plugins

Harness IDP supports a curated collection of plugins to integrate the software catalog with third-party providers and extend functionality:

Plugin Type	Description	Documentation
Harness Native Plugins	Official plugins that integrate seamlessly with other Harness modules (CI/CD, Feature Flags, Chaos Engineering, STO, etc.)	View Harness Plugins
Backstage Community Plugins	Third-party and community plugins from the Backstage ecosystem	View Available Plugins
Custom Plugins	Build your own frontend plugins for specific use cases	Build Custom Plugins

SECRET MANAGEMENT FOR PLUGINS

Harness IDP requires some secrets to be set for plugins and external integrations in the Catalog to work. We support all types of secret managers for secure credential storage.

5. Harness IDP workflow backends

Harness Pipelines: Self-service workflows in Harness IDP are powered by Harness Pipelines. Each Workflow's backend is configured using Actions and Harness Pipelines. Go to Setting up the Backend with Harness IDP Pipeline for more information.

You can also use other tools (such as GitHub Actions or Jenkins) as the backend for your Workflows by triggering them via Harness Pipelines. However, these tools are not natively supported by Harness IDP, so the experience is not as seamless as with Harness Pipelines. We recommend using Harness Pipelines as the backend for your Workflows.

6. Harness IDP workflow actions

Harness IDP Workflows use custom actions to trigger and orchestrate Harness Pipelines. Go to Supported Workflow Actions for more information.
