Connect Shopify with EasyPost to pull live carrier rates, automate label buying and tracking updates, and reduce shipping errors at scale across high-volume order flows.
• Orders and ship-to addresses are pulled from Shopify and normalized into EasyPost shipment objects, with service, package, and weight fields passed through when available.
• Carrier accounts are linked in EasyPost, rate shopping returns available services, and the selected rate is stored against the shipment for label purchase.
• Shipping labels are generated in EasyPost and the label URL, tracking number, and carrier code are written back to Shopify as fulfillment data.
• Tracking events are received by EasyPost via carrier feeds and relayed through webhooks, then mapped to Shopify fulfillment status updates.
• Address validation and correction responses from EasyPost are applied to shipment creation, with exceptions flagged when records fail validation.
• Idempotent requests and deduplication keys reduce duplicate labels, while API responses and webhook payloads are logged for reconciliation and support.
