Scaling Magento 2 API: From Sequential Calls to Async Bulk Operations

API performance in Magento integrations is critical yet often overlooked—sequential REST calls inadvertently starve resources, lock databases, and destabilize storefronts.

This paradigm shift from sequential to batch-async processing is essential for scaling integrations without compromising system stability.
