define( "ID_INSTANCE", getenv("ID_INSTANCE" ));

Receiving incoming messages by HTTP API#
The general concept of receiving data in the Green API is described here. To start receiving messages by the HTTP API, you need to execute the library method:
greenApi.webhooks.startReceivingNotifications(onEvent)
onEvent - your method which should contain parameters:
Parameter | Description |
---|---|
typewebhook | received message type (string) |
body | message body (json) |
Message body types and formats here.
This method will be called when an incoming message is received. Next, process messages according to the business logic of your system.
Running index.php#
php -S localhost:8080
