Postman file

The Postman is a tool designed to test RESTful services (Web APIs) by sending HTTP requests and analyzing their responses.
Download Postman App Production
You should use the following URL:
https://api.positus.global/v2/whatsapp/numbers/{{chave}}/messages When you contract and activate your WhatsApp Business API account, we will provide a key per number and you will be able to generate your tokens through the platform. ⬇️ Download the Postman collection — Production (2026)

Sandbox API

Development
You should use the following URL:
https://api.positus.global/v2/sandbox/whatsapp/numbers/{{chave}}/messages
Create your sandbox account through the link https://studio.posit.us/ and generate a token by following the on-screen instructions. Navigate to the “Webhook” menu and copy the POST URL (it uses the “Key”).In the development environment you cannot send HSM messages, but all other features are available for sending and receiving.

C# - RestSharp

var client = new RestClient("https://api.positus.global/v2/sandbox/whatsapp/numbers/{{chave}}/messages");
client.Timeout = -1;
var request = new RestRequest(Method.POST);
request.AddHeader("Content-Type", "application/json");
request.AddHeader("Authorization", "Bearer xxxx");
request.AddParameter("application/json,text/plain", "{\r\n  \"to\": \"+5511999999999\",\r\n  \"type\": \"text\",\r\n  \"text\": {\r\n      \"body\": \"your-message-content\"\r\n  }\r\n}",  ParameterType.RequestBody);
IRestResponse response = client.Execute(request);
Console.WriteLine(response.Content);

PHP - cURL

Python - http.client

import http.client
import mimetypes
conn = http.client.HTTPSConnection("api.positus.global")
payload = "{\r\n  \"to\": \"+5511999999999\",\r\n  \"type\": \"text\",\r\n  \"text\": {\r\n      \"body\": \"your-message-content\"\r\n  }\r\n}"

data = res.read()
print(data.decode("utf-8"))

Nodejs - Request

var request = require('request');
var options = {
  'method': 'POST',
  'url': 'https://api.positus.global/v2/sandbox/whatsapp/numbers/{{chave}}/messages',
  'headers': {
    'Content-Type': ['application/json'],

};
request(options, function (error, response) { 
  if (error) throw new Error(error);
  console.log(response.body);
});

JavaScript - JQuery

var settings = {
  "url": "https://api.positus.global/v2/sandbox/whatsapp/numbers/{{chave}}/messages",
  "method": "POST",
  "timeout": 0,
  "headers": {
    "Content-Type": ["application/json"],

};

$.ajax(settings).done(function (response) {
  console.log(response);
});

PowerShell - RestMethod

$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
$headers.Add("Content-Type", "application/json")
$headers.Add("Authorization", "Bearer xxxx")

$body = "{
`n  `"to`": `"+55119999999999`",
`n  `"type`": `"text`",

`n}"

$response = Invoke-RestMethod 'https://api.positus.global/v2/sandbox/whatsapp/numbers/{{chave}}/messages' -Method 'POST' -Headers $headers -Body $body
$response | ConvertTo-Json

Go - Native
