Send Group message

How to create a WhatsApp group or send messages to the group

All Group API Calls to work with WhatsApp groups: https://whapi.readme.io/reference/getgroups

To send a message to a group you need to know the group ID.

You can get the group ID in several ways:

When you create a group, the group ID will be specified in the response from the API;
Get a list of groups (method: https://whapi.readme.io/reference/getgroups );
Get a list of all chats (method: https://whapi.readme.io/reference/getchats );

The group ID looks like this: 120363194020948049@g.us. This information cannot be seen in the application or Web version!

Once you know the group ID, you can use the method to send any message. For example, a text message

In the to parameter you insert the ID of the group you want to send the message to. And in the body, the text of the message.

How to create a group via API

Now that your group is up and running, it's time to acquire its unique identifier. Make a quick call to /getgroup and you'll have what you need.
With the identifier in your grasp, you're all set to spread the word! Use POST /sendmessagetext to shower your group with your initial messages.
