### Checking for membership of a GitHub Organisation
:::info
Requires authentik 2021.12.5.
:::
To check if the user is member of an organisation, you can use the following policy on your flows:
```python
accepted_org = "foo"
# Get the user-source connection object from the context, and get the access token
connection = context['goauthentik.io/sources/connection']
access_token = connection.access_token
# We also access the user info authentik already retrieved, to get the correct username
github_username = context["oauth_userinfo"]
# Github does not include Organisations in the userinfo endpoint, so we have to call another URL
orgs = requests.get(
"https://api.github.com/user/orgs",
auth=(github_username["login"], access_token),
headers={
"accept": "application/vnd.github.v3+json"
}
).json()
# `orgs` will be formatted like this
# [
# {
# "login": "beryjuorg",
# [...]
# }
# ]
user_matched = any(org['login'] == accepted_org for org in orgs)
if not user_matched:
ak_message(f"User is not member of {accepted_org}.")
return user_matched
```
If a user is not member of the chosen organisation, they will see this message
