GitHub App Integration for Codecov Self-Hosted


The GitHub App Integration allows Codecov to:

  1. Provide login with GitHub functionality to end users.
  2. Post comments and status on Pull Requests in GitHub
  3. Sync Codecov state to GitHub via webhooks
  4. Provide fine grained controls for determining which GitHub repositories Codecov can access.


This Approach works for both GitHub and GitHub Enterprise

Regardless of which github version you're using this approach can work for either. However you will need to be mindful of adapting the code snippets to your particular scenario (i.e., github, or github_enterprise in the codecov.yml)

Creating a GitHub App Integration


Enable webhooks

Webhooks need to be enabled for the GitHub App to work. This is the method the app uses to connect and communicate with Codecov.

To create a GitHub App Integration for Codecov, first navigate to your organization in the GitHub UI.


You can use the drop down in the left sidebar of the Settings page in GitHub to access your organization.

Then from the Sidebar Click Developer Settings > GitHub Apps:

Choose "New GitHub App":


Create the App for your Organization

When creating the GitHub app, ensure that you're creating it for your organization, not your personal account. The URL on the app creation page should read:

And fill out the relevant fields for app creation:

It's important to set the proper callback URL. They should point to your Codecov Self-Hosted install as follows:

  • <your-codecov-self-hosted-url>/login/ghe

For the webhook URL:

  • <your-codecov-self-hosted-url>/webhooks/github_enterprise

You should provide a secret.

    webhook_secret: "<some-secret>"

Once provided, you will want to ensure that you properly provide the secret in the Codecov Self-Hosted codecov.yml.


The following screenshot shows all permissions needed by the app integration, as well as the relevant events. For visibility permissions with a greater setting than "No Access" have been emphasized in green.

Repository Permissions


Required repository permissions.

Organization Permissions


Required organization permissions

User Permissions

Email address read is required. All others can be set to "No Access"



Required user permissions.



If you're not using GitHub Enterprise, make sure that you only publish this app for your organization.

Use the GitHub App for Login

Once the GitHub App is created, a Client ID will be generated automatically by GitHub. Additionally you will need to generate a new Client Secret for the App in the GitHub user interface. Once this is done, you can use the client id and secret as part of the github configuration in the codecov.yml as follows:

  client_id: "<client-id>"
  client_secret: "<client-secret>"

Once these values are supplied and the Codecov instance restarted, login via GitHub should be functional.

Generate and Add a PEM file to Codecov.


Adding a PEM file to Codecov is highly encouraged!

The PEM file allows Codecov to post pull request comments and update statuses on GitHub. Not adding a PEM file may cause Codecov to malfunction.

After creating the GitHub App, Github will prompt you to create a .pem file from the github ui. This will result in a .pem file you can download. Once downloaded you will need to place this file in the same directory as your codecov.yml and docker-compose.yml and update your docker-compose.yml as follows:

  #... other configuration
  	- ./file.pem:/config/file.pem 
  #... other configuration
  	- ./file.pem:/config/file.pem

You will need to add the integration and webhook_secret sections to the github (or github_enterprise) section of your codecov.yml as follows:

# ...
  webhook_secret: "ff523b3162ef64604f03c94459"

# values from the Github App integration
    id: 63040 # App ID value shown on 
your integration's page in GitHub
    pem: /config/file.pem # path to the pem file you 
created in the `web` and `worker` containers.

Install App Integration to your organizations

Depending on your GitHub settings, you may have to install the Codecov Github App on any organizations that you wish to use it with. This can be done from the app settings screen.

After installing the app you can verify installation on the organization's installed GitHub apps page.


  • If you don't receive comments on Pull Requests for Repositories with the App Integration installed, visit the repo settings page for that particular repository on your Codecov Enterprise install:


For GitHub Enterprise:

Once there, check the "GitHub Webhook" section and press the "Create Web Hook" button if a webhook is not already set.
