How to receive incoming notifications#

To receive incoming webhooks, you must send a handler function to Webhook().Start. The handler function should have one parameter (body map[string]interface{}). When you receive a new notification, your handler function will be executed. To stop receiving incoming webhooks, you need to call Webhook().Stop.

Link to example: webhook/main.go.

GreenAPIWebhook := GreenAPI.Webhook()

GreenAPIWebhook.Start(func(body map[string]interface{}) {
    fmt.Println(body)
})

Running the application#

go run main.go
