GroupDecreaseGroupCounter

introduction

Decrease Group Counter

If the counter's key exists, it is decremented by the group_counter_value passed in directly from the current value; conversely, the key is added and decremented by the group_counter_value passed in from the default value of 0

The group counter supports all group types except for communities and topics.

Parameter details

overload1

Parameter name Parameter type Required Description
group_id string Required Group ID
group_counter_key string Required Group Counter Key
group_counter_value ulong Required Decreasing amount of change in group counter
callback ValueCallback < List < GroupCounter > > Required Asynchronous callback.

overload2

Parameter name Parameter type Required Description
group_id string Required Group ID
group_counter_key string Required Group Counter Key
group_counter_value ulong Required Decreasing amount of change in group counter
callback ValueCallback< string > Required Asynchronous callback. The format of json_param in the return value is string

Returned template

TIMResult

The parameters of the callback function after successfully calling the API：
code:int
desc:string
json_param:List<GroupCounter>
user_data:string

Return value details

name type description
TIMResult TIMResult Return value of calling API
code int Result error code: Error Codes
desc string The description of the error.
json_param string Json string. Calling different API will get different Json strings.
user_data string User-defined data transfered by ImSDK without any processing
