Invite as members

Invites one or more users as members to a group channel. Users can join a group channel immediately after receiving an invitation, without having to accept it. To give users an option to accept or decline an invitation, see update default channel invitation preference or update channel invitation preference. See this page to learn more about channel types.

Note: By default, blocked users are included when sending invitations. If you wish to exclude blocked users, contact our sales team.

Request body

The following table lists the properties of an HTTP request that this action supports.

Properties

Required	Type	Description
user_ids[]	array of strings	Specifies an array of one or more user IDs to invite to the channel. Up to 100 users can be invited at a time. The `users` property can be used instead of this property.
users[]	array of objects	Specifies a list of one or more `JSON` objects containing the `user_id` property to invite to the channel. Up to 100 users can be invited at a time. The `user_ids` property can be used instead of this property.

Optional	Type	Description
invitation_status	object	Specifies one or more `key-value` pair items which set the invitation status of each user invited to the channel. Each key-value pair should be specified with the invited user's ID, a colon (:), and the user’s invitation status (for example, `user_id_1: invitation status`). Acceptable values are `joined`, `invited_by_friend`, and `invited_ by_non_friend`. (Default: `joined`)
hidden_status	object	Specifies one or more key-value pair items which set the channel's hidden status for each user. The value in `hidden_status` determines whether to hide the channel from the user's channel list. Each key-value pair should be specified with the invited user's ID, a colon (:), and the channel's hidden status (for example, `user_id_1: channel hidden status`). Acceptable values are the following: - `unhidden` (default): the channel is shown when a user's channel list is retrieved. - `hidden_allow_auto_unhide`: if a new message is sent to a hidden channel, the channel automatically reappears on a user's channel list. - `hidden_prevent_auto_unhide`: the channel doesn't reappear on a user's channel list even when a new message is sent to that channel.
inviter_id	string	Specifies the ID of a user who invites other users to the channel. The inviter isn't automatically registered to the channel as a member, so you should specify the ID of the inviter in the `user_ids` property if needed.
