When you create a new group, an invite link is created for inviting participants to the group. Since you cannot manually add participants to the group, simply send a message with your invite link to WhatsApp users who you would like to join the group. ## Group management features [Create and delete group](https://developers.facebook.com/documentation/business-messaging/whatsapp/groups/reference#create-group) [Groups with join requests enabled](https://developers.facebook.com/documentation/business-messaging/whatsapp/groups/reference#groups-with-join-requests) [Get and reset group invite link](https://developers.facebook.com/documentation/business-messaging/whatsapp/groups/reference#get-and-reset-group-invite-link) [Send group invite link template message](https://developers.facebook.com/documentation/business-messaging/whatsapp/groups/reference#send-group-invite-link-template-message) [Remove group participants](https://developers.facebook.com/documentation/business-messaging/whatsapp/groups/reference#remove-group-participants) [Get group info](https://developers.facebook.com/documentation/business-messaging/whatsapp/groups/reference#get-group-info) [Get active groups](https://developers.facebook.com/documentation/business-messaging/whatsapp/groups/reference#get-active-groups) [Update group settings](https://developers.facebook.com/documentation/business-messaging/whatsapp/groups/reference#update-group-settings) To learn how to message groups, view the [Group Messaging reference](https://developers.facebook.com/documentation/business-messaging/whatsapp/groups/groups-messaging). ## Subscribe to groups metadata webhooks In order to receive webhook notifications for metadata about your groups, please subscribe to the following webhook fields: `group_lifecycle_update` `group_participants_update` `group_settings_update` `group_status_update` For a full reference of webhooks for the Groups API, please visit our [Webhooks for Groups API reference](https://developers.facebook.com/documentation/business-messaging/whatsapp/groups/webhooks). ## Create group Use this endpoint to create a new group and generate a group invite link. Once the group is created, you will receive a webhook with an `invite_link` parameter that contains an invite link for the group. You can send this invite link to WhatsApp users interested in joining the group. Optionally, you can create a group that requires join approval. This means that if a WhatsApp user wants to join your group, you can approve or reject their request. [Learn more about groups with join requests enabled](https://developers.facebook.com/documentation/business-messaging/whatsapp/groups/reference#groups-with-join-requests). ### Request syntax Create a group with an initial group invite link: `POST /<BUSINESS_PHONE_NUMBER_ID>/groups` ### Request body ``` \{   "messaging_product": "whatsapp",   "subject": "<GROUP_SUBJECT>",   "description": "<GROUP_DESCRIPTION>",   "join_approval_mode": "<JOIN_APPROVAL_MODE>" } ``` ### Request parameters | Placeholder | Description | Sample Value | | ------------------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------ | | `<BUSINESS_PHONE_NUMBER_ID>`

Values can be:

`auto_approve` — Indicates WhatsApp users can join the group without approval.
If omitted, `join_approval_mode` is set to `auto_approve` by default. | `auto_approve` | ### Webhooks A `group_lifecycle_update` webhook is triggered. #### Group create succeed [View the “Group create succeed” sample webhook](https://developers.facebook.com/documentation/business-messaging/whatsapp/groups/webhooks#group-create-succeed) #### Group create fail [View the “Group create fail” sample webhook](https://developers.facebook.com/documentation/business-messaging/whatsapp/groups/webhooks#group-create-fail) #### User joins group using invite link [View the “User joins group using invite link” sample webhook](https://developers.facebook.com/documentation/business-messaging/whatsapp/groups/webhooks#user-joined-group-using-invite-link-succeed) ## Groups with join requests You can create groups that require join request approval. Once enabled, WhatsApp users who click the group invitation link can submit a request to join the group, or cancel a prior request: When a WhatsApp user joins the group using a join request, a \[`group_participants_update` webhook for a user accepting the join request] (/documentation/business-messaging/whatsapp/groups/webhooks#user-accepts-or-cancels-join-request) is triggered. You can also [get a list of open join requests via API](https://developers.facebook.com/documentation/business-messaging/whatsapp/groups/reference#get-join-requests).

Use these pre-defined templates to send group invitations as utility messages. **In order to keep the template priced as `utility`, you cannot modify it when you copy it from template library to your WABA.** To send the template message: #### Step 1. Add a group invite link template in Template Library to your account templates: *In WhatsApp Manager* Navigate to [Template Library](https://business.facebook.com/wa/manage/template-library) On the left, click the **Group invite link** dropdown, then click the **Group invite upon request** checkbox. Select the template you want to use, give it a name, and click **Submit**. *Via the API* You can query template libraries applicable to group invite links using the request below: `GET /message_template_library?category=utility&topic=group_invite_link&language=en` [Read more about finding and adding the template to your WABA via the api](https://developers.facebook.com/documentation/business-messaging/whatsapp/templates/template-library#using-the-api) Template approval may require up to 24 hours. You’ll be able to send messages with this template after its approval. #### Step 2.
