How to give repository access to installed GitHub app

Question

I am using google cloud build for CI/CD purpose, in which I need to give access for specific repositories (can't use All repositories option). Is there any way to provide access by repository wise through python code. If not possible through python is there any alternative to this requirement.

Thanks,

Raghunath.

When I checked with GitHub support, they have shared me below links.

To get repository id -- https://developer.github.com/v3/repos/#get-a-repository

To get installations details -- https://developer.github.com/v3/orgs/#list-installations-for-an-organization

To add repository to an installation -- https://developer.github.com/v3/apps/installations/#add-repository-to-installation

I used these links to create below mentioned code which has helped me to implement the desired requirement.

# Header to use in request
header = dict()
header['Authorization'] = 'token %s' % personal_token
header['Accept'] = 'application/vnd.github.machine-man-preview+json'

# Fetching repository id
url = f'https://api.github.com/repos/{organization_name}/{repo_name}'
output = requests.get(url, headers=header)
repo_id = output.json()['id']

# Adding repository to Google Cloud build installation
url = f'https://api.github.com/user/installations/{gcb_installation_id}/repositories/{repo_id}'
output = requests.put(url, headers=header)
