Getting Started

Account Setup

1. Create an Account — Register a Waija account using the registration form.
2. Verify Your Email — Confirm your email from the backoffice after registration.
3. Configure Callback URL — In Settings, set the endpoint that receives game and balance callbacks.
4. Retrieve API Base URL — Copy it from Settings. All method calls go here.
5. Generate API Credentials — Every request needs api_login and api_password.
6. Whitelist Server IPs — Requests from other IPs are blocked.
7. Integrate the API — Try a method in the API Console, or use the PHP client.

PHP Client

If your project uses PHP, we provide a Composer package to speed up integration.

• GitHub package: slotsgateway/slotsgateway-php-client
• Install via Composer:

composer require slotsgateway/slotsgateway-php-client

Full usage — methods, callback helpers, Laravel — is on the PHP Client page.

API Requests

All game-server requests are POST with a JSON body. Always include:

{
  "api_login": "d13b1ceb-6209-4163-b1cf-f304c28b81ec",
  "api_password": "dqRin2nfLosij2n88"
}

Callback Communication

The game server sends GET requests to your callback URL. Respond with JSON:

• error — error code
• balance — integer in cents ($2.50 → 250)

Always HTTP 200. If you cannot resolve the player, return balance 0.

Successful Response

{ "error": 0, "balance": 250 }

Insufficient Balance

{ "error": 1, "balance": 250 }

Processing Error

{ "error": 2, "balance": 0 }
