How to initialize an object#

GreenAPI := api.GreenAPI{
    IDInstance:       "1101000001",
    APITokenInstance: "d75b3a66374942c5b3c019c698abc2067e151558acbd412345",

Note that keys can be obtained from environment variables:

IDInstance := os.Getenv("ID_INSTANCE")
APITokenInstance := os.Getenv("API_TOKEN_INSTANCE")

How to send a message#

If an API method has optional parameters, you have to pass JSON to the library method (map[string]interface{}).

Link to example: sendMessage/main.go.

response, _ := GreenAPI.Methods().Sending().SendMessage(map[string]interface{}{
    "chatId":  "",
    "message": "Any message",

Running the application#

go run main.go
