Fetching User Profile:
When a follower and an Official Account have corresponded through chat messaging, the Official Account can receive the follower’s OpenID. The OpenID is a unique encrypted WeChat ID for each user of an Official Account, and users can have separate OpenIDs corresponding to different Official Accounts.
This API enables Official Accounts to obtain a user’s basic information via the OpenID, including nickname, profile photo, gender, city, language and time at which the user initially followed the Official Account.
Developers can call these APIs to query, create, change a group or change a user’s group.
This API enables Official Accounts to obtain a follower list that contains several OpenIDs (unique encrypted WeChat IDs for each user of an Official Account). Each user has separate OpenIDs that correspond to different Official Accounts. Developers can fetch up to 10,000 OpenIDs by calling this API once. This API can be called multiple times.
