//
// You can use v1.New or v1.NewWithClient to initialize API client. github.com/retailcrm/mg-transport-api-client-go/examples
// package contains some examples on how to use this library properly.
//
// Basic usage example:
//
//	client := New("https://message-gateway.url", "cb8ccf05e38a47543ad8477d4999be73bff503ea6")
//	getReplyDeadline := func(after time.Duration) *time.Time {
//		deadline := time.Now().Add(after)
//		return &deadline
//	}
//	resp, status, err := client.Messages(SendData{
//		Message: Message{
//			ExternalID: "uid_1",
//			Type:       MsgTypeText,
//			Text:       "Hello customer!",
//			PageLink:   "https://example.com",
//		},
//		Originator: OriginatorCustomer,

//		ReplyDeadline:  getReplyDeadline(24 * time.Hour),
