Integrating with LoyVerse POS – A proper Guide

LoyVerse POS is a popular point-of-sale system for small businesses, offering APIs for seamless third-party integrations. Here’s a concise, developer-focused loyverse integration

Step 1: Access LoyVerse Developer Portal

1. Register as a Developer:
2. Create an account on the LoyVerse Developer Portal.
3. Generate API credentials (Client ID and Client Secret) for authentication.
4. Review API Documentation:
5. Study endpoints for key operations:
6. Items: Retrieve or update product catalogs.
7. Orders: Access sales data.
8. Inventory: Sync stock levels.

Step 2: Implement OAuth 2.0 Authentication
Request Authorization:

Redirect users to LoyVerse’s OAuth 2.0 authorization URL:
Copy
https://cloud.loyverse.com/oauth/authorize?client_id=YOUR_CLIENT_ID&redirect_uri=YOUR_REDIRECT_URI&response_type=code

Exchange Code for Tokens:

Use the returned authorization_code to fetch access_token and refresh_token via POST to /oauth/token
.

Step 3: Call LoyVerse APIs

Fetch Data:

Use the access_token to call endpoints like /v1/items or /v1/orders.

Example (Python):

python
Copy
import requests

headers = {‘Authorization’: ‘Bearer YOUR_ACCESS_TOKEN’}

response = requests.get(‘https://api.loyverse.com/v1/items‘, headers=headers)

Handle Pagination:

LoyVerse APIs paginate large datasets. Loop through cursor parameters to retrieve all records.

Step 4: Set Up Webhooks (Optional)
Subscribe to Events:

Register webhooks to receive real-time updates (e.g., new orders, inventory changes).

Use the /v1/webhooks endpoint to configure URLs for events like ORDER_CREATED or ITEM_UPDATED.

Verify Signatures:

Validate incoming webhook payloads using the X-Loyverse-Webhook-Signature header.

Step 5: Test in Sandbox Mode
Use LoyVerse’s sandbox environment to mock API interactions without affecting live data.

Simulate edge cases (e.g., out-of-stock items, refunds).

Step 6: Deploy & Monitor

Rate Limits: LoyVerse enforces rate limits (e.g., 60 requests/minute). Implement retries with exponential backoff.

Logging: Track API errors (e.g., 401 Unauthorized, 429 Too Many Requests
