About
-
Collaborator integrates with Git repositories hosted at GitHub.com, as well as on GitHub Enterprise servers in your network.
-
When you integrate Collaborator with a GitHub repository, your Collaborator server creates reviews automatically for pull requests in the repo, as well as for push events that occur in that repo. For complete information on how the integration works, see Integration With Repository Hosting Services.
-
To inform Collaborator about changes, GitHub uses a webhook that sends notification messages to your Collaborator server.
-
To set up the webhook and other integration parameters, you need to set up some options in Collaborator and in GitHub. See the rest of this topic for details.
Supported Hosting Services
-
GitHub (github.com)
-
GitHub Enterprise
Requirements
-
Your Collaborator server must be accessible to GitHub and vice versa. You may need to configure your firewall or enable tunneled connections to expose the server’s External URL to the Web. If needed, ask your system administrator for help.
-
To configure integration settings in Collaborator, you need Administrator privileges.
1. Get GitHub Tokens
To integrate with GitHub, you need a personal access token that will be used to access your repositories.
For detailed information on generating a personal access token, follow instructions on this page of GitHub documentation:
https://help.github.com/articles/creating-an-access-token-for-command-line-use/
Notes:
-
When setting up the token parameters, make sure to enable the following scopes for the token:
repoadmin:orgadmin:repo_hook, andadmin:org_hook
-
After GitHub generated the token, save it somewhere or write it down. We will need the token later, when we will configure the integration between Collaborator and GitHub.
2. Set Up Integration
Collaborator offers two groups of settings for configuring integration with remote repositories:
| Settings | When to use |
|---|---|
| Easy Add Repository tab | We recommend using these settings to set up new connections to your repositories quickly. |
| Use these settings to configure existing connections. Though you can use these settings to set up integration, the settings on the “Easy Add Repository” tab will help you do this faster. |
Additionally, you can create auto-polling configuration to periodically look for new repositories on the specified server and suggest creating integrations for them.
Easy Add Repository tab (recommended)
-
Log in to Collaborator as administrator. (To integrate with GitHub repositories, you need administrator privileges in Collaborator).
-
On the Collaborator main toolbar, click ADMIN, and then select Repository Hosting Services from the tree on the left. Then switch to the Easy Add Repository tab.
-
On the tab, select GitHub in the Add repository for box and click Next:

Important: Click this button, when you set up integration with your repository for the first time.To learn more about webhook settings on the GitHub side, see GitHub documentation:
-
Click Test Connection to verify if you entered data correctly.
Click Save to store the settings.
Creating GitHub auto-polling configuration
Sections above describe how to add integrations for existing repositories. When some new repositories are created on a server, you may integrate them manually. Alternatively, you can setup GitHub auto-polling configuration that will periodically look for new repositories on the specified server, organization, team or user and suggest creating integrations for them.
-
Log in to Collaborator as administrator. (To integrate with GitHub repositories, you need administrator privileges in Collaborator).
-
On the Collaborator main toolbar, click ADMIN, and then select Repository Hosting Services from the tree on the left. Then switch to the Repository Auto-Polling tab.
-
On the tab, select GitHub in the Add configuration box and click Next.
-
Collaborator will displays a page with connection details.
Click the image to enlarge it.
Fill in the edit boxes:
Setting Description Server URI Required. The URI of GitHub server, user, organization or team to be polled for new repositories. Token
Required. The personal access token of the GitHub account.
This is the token that we generated in GitHub earlier.
Scopes for user
Optional. Defines which types of repositories to fetch
Scope Description Owner (default) Repositories that are owned by the specified user Collaborator Repositories that the user has been added to as a collaborator.
Webhooks will be created for those repositories where allowed by the repository permissions for the specified user.Organization member Repositories that the user has access to through being a member of an organization. This includes every repository on every team that the user is on.
Webhooks will be created for those repositories where allowed by the repository permissions for the specified user.After specifying these values, you can click Test connection to verify if you entered data correctly.
- After you specified the values, click Save. This will create an auto-polling configuration and display it in the Auto-Polling Configurations List.
- Scroll down the Repository Auto-Polling tab and check that the Enable Auto-Polling setting is on and optionally change the Auto-Polling Interval setting.
Now Collaborator will automatically check if any new repositories were found on the specified server. Once found, it will notify administrators and suggest creating integrations with these newly created repositories via the Easy Add Repository wizard.
3. Link Collaborator User Account to GitHub Account
The last step is to link Collaborator user accounts to the GitHub accounts. See —
Enable/Disable configuration
Once a new repository configuration is created, it is enabled automatically. However, you can enable and disable integration with GitHub manually. To do this:
- In Collaborator, go to ADMIN > Remote System Integrations.
- In the Integration Status section find the Enable GitHub Integration setting and change it to Yes or No, respectively.

Known Issues and Specifics
-
If repository contains a CODEOWNERS file that defines users responsible for certain files in a repository and integration can match those GitHub users with Collaborator users, and the Auto assign reviewers option is on, then it will automatically add those users as reviewers on Collaborator's side.
-
You can specify GitHub users as reviewers when you are creating a pull request. If your teammates link their GitHub accounts with their Collaborator accounts correctly, and the Auto assign reviewers option is on, then Collaborator will automatically add those users as reviewers to the created review on the Collaborator side.
-
Similarly, you can specify some team as reviewer when creating pull request on the GitHub side, or specify team in CODEOWNERS file. In this case, integration tries to match members of that team with Collaborator users, and if the Auto assign reviewers option is on, it will automatically add those users as reviewers on Collaborator side.
-
If your GitHub repositories use continuous integration, the Remote System Links section will also display current build statuses of your CI systems (Jenkins, Travis and so forth).
-
You can secure webhook calls by providing a secret token when you are creating or modifying a webhook and integration settings in GitHub and in Collaborator. This token will be used as server signature for verifying webhook events. The webhook token is optional and is absent by default.
-
To avoid creating reviews for merge commits, keep their messages default or start them with the Merge pull request # substring.
-
If the remote repository server is not accessible, Collaborator will retry connecting after a certain time period and will perform several retry attempts. Wait time is increased with each attempt: wait_time*1, wait_time*2, wait_time*3 and so on. Default wait time is 1 second and Collaborator will perform 3 retries. Wait time and maximal number of attempts could be configured via Java VM Options. If the server did not respond after all attempts, Collaborator will mark the respective webhook as inactive and put an exception to the remoteSystem.log
-
Right after you set up integration with some GitHub repo, the very first push or pull request to this repo will not be tracked. Subsequent requests will be tracked as they should.
