Greetings developers!
We are excited to announce that we have released an update to the World of Warcraft Game Data and Profile APIs that includes several new endpoints. These endpoints are currently available for World of Warcraft; they are not available for World of Warcraft Classic.
Game Data API
Endpoints:
/data/wow/reputation-tiers/index/data/wow/reputation-tiers/{id}/data/wow/reputation-faction/index/data/wow/reputation-faction/{id}
Namespace: static-{region}. See the World of Warcraft Namespaces Documentation for more information.
Profile API
Data for the Profile API endpoints below is only available for characters that have logged out of World of Warcraft after this week’s weekly reset.
Endpoints:
/profile/wow/character/{realm}/{name}/reputations/profile/wow/character/{realm}/{name}/hunter-pets/profile/wow/character/{realm}/{name}/collections/profile/wow/character/{realm}/{name}/collections/pets/profile/wow/character/{realm}/{name}/collections/mounts/profile/wow/character/{realm}/{name}/status
Namespace: profile-{region}. See the World of Warcraft Namespaces Documentation for more information.
To explore these endpoints further, check out our official API Reference documentation on the Developer Portal, located here: WoW Game Data API Reference and WoW Profile API Reference.
Happy coding! 
Do you have any plans to include display ID with hunter and companion pets API data? We as content providers cannot provide correct appearances for pets without that, as many can come in multiple colours.
