Discord

8. Under Directory -> Federation & Social login Click Create Discord OAuth Source

9. Name: Choose a name (For the example I used Discord)

10. Slug: discord (You can choose a different slug, if you do you will need to update the Discord redirect URLand point it to the correct slug.)

11. Consumer Key: Client ID from step 4

12. Consumer Secret: Client Secret from step 5

Here is an example of a complete authentik Discord OAuth Source

Save, and you now have Discord as a source.

:::note For more details on how-to have the new source display on the Login Page see here. :::

Checking for membership of a Discord Guild

:::info Ensure that the Discord OAuth source in 'Federation & Social login' has the additional guilds scope added under the 'Protocol settings'. :::

Create a new 'Expression Policy' with the content below, adjusting the variables where required:

# To get the guild ID number for the parameters, open Discord, go to Settings > Advanced and enable developer mode.
# Right-click on the server/guild title and select "Copy ID" to get the guild ID.

ACCEPTED_GUILD_ID = "123456789123456789"
GUILD_NAME_STRING = "The desired server/guild name in the error message."

# Only change below here if you know what you are doing.

# Ensure flow is only run during OAuth logins via Discord
if context['source'].provider_type != "discord":
    return True

# Get the user-source connection object from the context, and get the access token
connection = context.get("goauthentik.io/sources/connection")
if not connection:
  return False
access_token = connection.access_token

guilds = requests.get(
    "https://discord.com/api/users/@me/guilds",
    headers= {
        "Authorization": f"Bearer {access_token}",
    }
).json()

user_matched = any(ACCEPTED_GUILD_ID == g["id"] for g in guilds)
if not user_matched:
    ak_message(f"User is not a member of {GUILD_NAME_STRING}.")
return user_matched

Now bind this policy to the chosen enrollment and authentication flows for the Discord OAuth source.

Checking for membership of a Discord Guild role

:::info Ensure that the Discord OAuth source in 'Federation & Social login' has the additional guilds guilds.members.read scopes added under the 'Protocol settings'. :::

Create a new 'Expression Policy' with the content below, adjusting the variables where required:

# To get the role and guild ID numbers for the parameters, open Discord, go to Settings > Advanced and
# enable developer mode.
# Right-click on the server/guild title and select "Copy ID" to get the guild ID.
# Right-click on the server/guild title and select server settings > roles, right click on the role and click
# "Copy ID" to get the role ID.

ACCEPTED_ROLE_ID = "123456789123456789"
ACCEPTED_GUILD_ID = "123456789123456789"
GUILD_NAME_STRING = "The desired server/guild name in the error message."
ROLE_NAME_STRING = "The desired role name in the error message."

# Only change below here if you know what you are doing.
GUILD_API_URL = f"https://discord.com/api/users/@me/guilds/{ACCEPTED_GUILD_ID}/member"

# Ensure flow is only run during OAuth logins via Discord
if context['source'].provider_type != "discord":
    return True

# Get the user-source connection object from the context, and get the access token
connection = context.get("goauthentik.io/sources/connection")
if not connection:
  return False
access_token = connection.access_token

guild_member_object = requests.get(
    GUILD_API_URL,
    headers= {
        "Authorization": f"Bearer {access_token}",
    }
).json()

user_matched = any(ACCEPTED_ROLE_ID == g for g in guild_member_object["roles"])
if not user_matched:
    ak_message(f"User is not a member of the {ROLE_NAME_STRING} role in {GUILD_NAME_STRING}.")
return user_matched

Now bind this policy to the chosen enrollment and authentication flows for the Discord OAuth source.
