    Profile Fields

    A profile is a set of data that describes user properties. IM’s profile system supports standard and custom profile fields. Profile fields have the following characteristics:

    • Profile fields are expressed in key-value format.

    • Key is of string type, and its name contains only uppercase and lowercase letters, numbers, and underscores.

    • Value has the following types:
      a. An integer of uint32_t type (not supported for custom fields)
      b. An integer of uint64_t type (not supported for custom fields)
      c. A string of string type (the length of the string cannot exceed 500 bytes)
      d. A buffer of bytes type (the length of the buffer cannot exceed 500 bytes)

    • You can configure the read and write permissions for each key. The read and write permissions of profile fields are as follows:

    Permission Name Permission Type Notes
    Read permission Readable by app
    Readable by app admin
    You can select one or more types of read permission.
    Write permission Writable by app
    Writable by app admin
    You can select one or more types of write permission.

    Custom Profile Fields

    Custom profile fields are the user data set by each app according to its own business needs. By using custom profile fields, an app can add additional data to user profiles and perform read and write operations through existing APIs.

    Applying for custom profile fields

    To apply for custom profile fields, the app admin can log in to the IM console and select Application Configuration > Feature Configuration. After the application is submitted, custom profile fields will take effect in 5 minutes.
    When applying for custom profile fields, you need to submit the following information for each field:

    Naming rules for custom profile fields

    The rules for naming custom profile fields are as follows:

    • The name of the custom profile field contains the prefix and keyword parts.
    • The prefix of the custom profile field is Tag_Profile_Custom.
    • Keyword: The keyword must be a string of letters with a length no more than 8 bytes. We recommend you use an English word or its abbreviation as the keyword.
    • Example: If the custom field to be applied for by an app has the keyword Test, then the name of the custom profile field is: Tag_Profile_Custom_Test.
