Guides - Open Guestbook API

Getting Started

1. Create an API Key

From the dashboard, generate a new API key with appropriate permissions for your project. Store it securely.

2. Set Up SDK

Install the Open Guestbook SDK or use any HTTP client to integrate with our REST API endpoints.

3. Make Your First Request

Use the v1/hello endpoint to verify your connection and see how JSON responses look.


curl -X GET \\
  -H 'Authorization: Bearer YOUR_API_KEY' \\
  https://api.openguestbook.tech/v1/hello

Code Integration

Choose your preferred language and follow the example below to start posting guestbook entries.

JavaScript Example


const OpenGuestbook = require('openguestbook-sdk');

const client = new OpenGuestbook.Client({
    apiKey: 'YOUR_API_KEY',
    version: '2025-08-01'
});

// Create a new entry
client.entries.create({
    name: 'Jane Doe',
    message: 'This API is amazing!'
}).then(response => {
    console.log('Entry created:', response);
}).catch(error => {
    console.error('Error:', error.message);
});

cURL with Authentication


curl -X POST \\
  -H 'Authorization: Bearer YOUR_API_KEY' \\
  -H 'Content-Type: application/json' \\
  -d '{"name": "John Smith", "message": "Love this platform!"}' \\
  https://api.openguestbook.tech/v1/entries

Response Example


{
  "id": "abc123xyz789",

  "message": "Exceptional service received today",
  "created_at": "2025-08-16T10:59:02Z"
}

Best Practices

Use Async Processing

Process large numbers of entries out of band using webhooks instead of synchronous requests.

Enable Rate Limiting

Set rate limits at the API key level to avoid accidental usage charges and request overloads.
