FAQPage Schema
How do I handle OAuth 2.0 authentication when integrating an external REST API?▼

OAuth 2.0 authentication for REST API integration is managed by handling user authorization flows using authlib. This allows your application to securely connect to external systems like Square or Shopify without managing raw credentials.

What is the best way to process incoming webhooks for real-time data synchronization?▼

Processing incoming webhooks for real-time data sync involves verifying payloads using HMAC and hashlib to ensure authenticity. Once verified, the system processes the incoming event data for immediate updates.

How do I prevent rate limiting errors during scheduled API synchronization tasks?▼

Rate limiting errors during scheduled API synchronization are prevented by implementing client-side rate limiting and circuit breakers. The tenacity library provides retry logic to handle transient API failures robustly.

Can I run background tasks for hourly inventory synchronization with Shopify?▼

Yes, you can run background tasks for hourly inventory synchronization with Shopify. The system uses Celery and asyncio to perform scheduled data syncs, ensuring accurate stock counts without blocking main operations.

Does this API integration approach support FastAPI for handling external requests?▼

Yes, this API integration approach supports FastAPI for handling external requests and structuring endpoints. It uses httpx for asynchronous HTTP requests and integrates seamlessly with background task execution.
