What is an inbound message?

An inbound message is a mobile message triggered from our WhatsApp Self Serve platform and routed to your callback URL.
For example, an inbound event is triggered when:

• You set a callback URL for your app, or you have used the proxy command to invoke your app on Gupshup Proxy bot phone number (+917834811114) to test the app in sandbox mode.
• An end-user gives their consent (opt-in) to receive notifications from your WhatsApp Business API number.

You will receive inbound asynchronous message events on your callback URL with a 5-second delay to ensure that users have enough time to persist the original message-id received for an outbound message.
