How to Send WhatsApp API Message using GO, Example

To send a text message, you need to make a request to:

POST https://gate.whapi.cloud/messages/text

Here's how you can dispatch a WhatsApp message using Golang:

package main

import (
	"fmt"
	"strings"
	"net/http"
	"io"
)

func main() {

	url := "https://gate.whapi.cloud/messages/text"

	payload := strings.NewReader("{\"typing_time\":10,\"to\":\"14409416972\",\"body\":\"Hello!\"}")

	req, _ := http.NewRequest("POST", url, payload)

	req.Header.Add("accept", "application/json")
	req.Header.Add("content-type", "application/json")
	req.Header.Add("authorization", "Bearer iNdBBvVS4sbBmwcPwcX1pzBDChVo2bcs")

	res, _ := http.DefaultClient.Do(req)

	defer res.Body.Close()
	body, _ := io.ReadAll(res.Body)

	fmt.Println(string(body))

}

The parameters are as follows:

• to: The recipient’s WhatsApp number in international format (e.g., 14409416972) or chatID for contact or group (e.g 14409416972@s.whatsapp.net or 12560234567890@g.us).

• body: The content of the message.
