Send Messages

This guide shows you how to send a message to an Instagram user from your Instagram professional account using the Instagram API with Instagram Login.

How It Works

The Instagram API with Instagram Login enables your app users to send and receive messages between their Instagram professional account and their customers, potential customers, and followers. Conversations can begin through their Instagram Feed, posts, story mentions, and other channels. When an Instagram user sends a message to your app user, an event is triggered, and a webhook notification is sent to your webhook server. The notification contains the Instagram user's Instagram-scoped ID (IGSID) and their message. Your app user can use this information to respond.

Messages can contain the following:

Audio files
GIFs
Images
Instagram posts (owned by your app user)

Links
Reactions
Stickers

Templates
Text
Videos
