Examples

Basic Usage

from blizzardapi2 import BlizzardApi

api_client = BlizzardApi("client_id", "client_secret")

# Public API endpoint (uses automatic client credentials token)
categories_index = api_client.wow.game_data.get_achievement_categories_index(
    "us",  # region
    "en_US"  # locale
)

# Protected API endpoint (requires user OAuth token)
summary = api_client.wow.profile.get_account_profile_summary(
    "us",
    "en_US",
    "user_access_token"  # OAuth token from authorization code flow
)

# WoW Classic endpoint
connected_realms_index = api_client.wow.game_data.get_connected_realms_index(
    "us",
    "en_US",
    is_classic=True
)

Token Management

The library automatically manages client credentials tokens for public endpoints:

from blizzardapi2 import BlizzardApi

api_client = BlizzardApi("client_id", "client_secret")

# First call: library automatically fetches and caches a client credentials token
realms = api_client.wow.game_data.get_realms_index("us", "en_US")

# Subsequent calls: library reuses the cached token
achievements = api_client.wow.game_data.get_achievements_index("us", "en_US")

# When token expires: library automatically refreshes it
# You don't need to manage tokens manually!

Access token vs Client ID/Client Secret

You can pass in a client_id and client_secret and use almost any endpoint except for a few that require an access_token obtained via OAuth authorization code flow. You can find more information at https://develop.battle.net/documentation/guides/using-oauth/authorization-code-flow.

Important: The library handles all tokens securely by passing them in Authorization headers, never in URLs. When you provide a user OAuth token to methods like get_account_profile_summary(), the library automatically:

1. Extracts the token from parameters
2. Sends it via Authorization: Bearer <token> header
3. Keeps tokens out of URL query strings

Here is the list of endpoints, specified by Blizzard, that require an OAuth token:

GET /oauth/userinfo
GET /profile/user/wow
GET /profile/user/wow/protected-character/{realm-id}-{character-id}
GET /profile/user/wow/collections
GET /profile/user/wow/collections/pets
GET /profile/user/wow/collections/mounts

Note: For these protected endpoints, you must implement the OAuth authorization code flow in your application to obtain a user access token. The library does not handle the OAuth flow itself - it only accepts and uses the token you provide.
