Wati SDK

A PHP SDK for the Wati.io WhatsApp API. Provides pre-built API classes for common operations.

Installation

This package requires PHP 8.3 or higher.

composer require "phpjuice/wati-sdk"

Setup

Get Your Credentials

1. Log in to your Wati Account
2. Navigate to API Docs in the top menu
3. Copy your API Endpoint URL and Bearer Token

Create a Client

<?php

use Wati\Http\WatiClient;
use Wati\Http\WatiEnvironment;
use Wati\Api\GetContacts;

// Get this URL from your Wati Dashboard (API Docs section)
// It includes your tenant ID: https://your-instance.wati.io/{tenantId}
$endpoint = "https://your-instance.wati.io/123456";
$bearerToken = "your-bearer-token";

// Create environment and client
$environment = new WatiEnvironment($endpoint, $bearerToken);
$client = new WatiClient($environment);

// Use pre-built API classes
$response = $client->send(new GetContacts());
$contacts = json_decode($response->getBody()->getContents(), true);

Usage with Laravel

The SDK includes a Laravel service provider for easy integration.

Configuration

Add the following to your config/services.php:

'wati' => [
    'endpoint' => env('WATI_ENDPOINT'),
    'token' => env('WATI_TOKEN'),
],

Add to your .env file:

WATI_ENDPOINT=https://your-instance.wati.io/123456
WATI_TOKEN=your-bearer-token

Usage in Laravel

The service provider is auto-discovered. Simply inject or resolve WatiClient:

use Wati\Http\WatiClient;
use Wati\Api\GetContacts;

class ContactController
{
    public function __construct(
        private readonly WatiClient $wati
    ) {}

    public function index()
    {
        $response = $this->wati->send(new GetContacts());
        return json_decode($response->getBody()->getContents(), true);
    }
}

Available API Classes

// Get the first page with 50 contacts (default)
$response = $client->send(new GetContacts());

// Get a specific page with a custom page size

} catch (AuthenticationException $e) {
    // Invalid bearer token - check credentials
} catch (RateLimitException $e) {
    // Rate limited - wait and retry
    $retryAfter = $e->getRetryAfter();
} catch (ValidationException $e) {
    // Invalid request parameters
    $errors = $e->getResponseData();
} catch (WatiApiException $e) {
