This guide provides technical best practices for developer teams on combining daily XML feed imports with real-time incremental status and attribute updates using Backend API patch endpoints.

Implementing a hybrid synchronization architecture ensures optimal catalog freshness while preventing unnecessary server load. This approach answers how you can maintain up-to-second product availability and pricing without running continuous full catalog imports.

To implement hybrid catalog synchronization, you will follow three primary steps:

Configure full daily XML feed imports for baseline catalog synchronization.
Integrate Backend API patch endpoints for real-time incremental attribute updates.
Manage state reconciliation and error handling between batch feeds and real-time patches.

Instruction & Implementation

Step 1: Baseline XML Feed Setup

Run a complete XML feed import on a regular daily schedule, typically during off-peak hours. The daily XML feed serves as the comprehensive source of truth for your entire catalog structure, categories, and static product metadata.

Requirements for daily feed configuration:

Generate a full XML file containing all active catalog items, categories, and attributes.
Assign a persistent unique identifier id or itemno) to every product record.
Schedule automated imports in Tweakwise Admin to establish the baseline catalog state each day or trigger the import from API (recommended).

Further feed guidelines are available in the XML Content Import Documentation.

Step 2: Real-Time Incremental Updates via Backend API

When high-frequency attributes change on your e-commerce platform—such as stock status, inventory counts, or price updates—trigger real-time patch requests to the Backend API endpoints.

Implementation steps for API patches:

Identify high-frequency event triggers in your e-commerce platform (e.g., checkout completion, inventory adjustments, or price updates).
Construct real-time patch payloads targeted directly at the specific product identifier.
Execute HTTP requests to the relevant Tweakwise Backend API patch endpoints to apply instantaneous updates.

Refer to the Tweakwise API Reference for full endpoint specifications and authorization details.

Step 3: Hybrid State Reconciliation

Maintain catalog consistency across both synchronization mechanisms by following key operational rules:

Use real-time API patches as short-term delta updates between full import cycles.
Allow the daily full XML feed to reconcile discrepancies and serve as the authoritative baseline.
Implement queue retries on your backend to handle temporary network failures gracefully during patch execution.

Notes & Important Considerations

Identifier Alignment: Ensure product identifiers (id or itemno) match identically between your XML feed definitions and real-time API patch payloads.
Overwrite Prevention: Avoid scheduling full XML feed imports during peak stock activity to prevent overwriting recent API patch states with stale feed export snapshots.
Request Throttling: Implement request debouncing or batching for high-frequency inventory changes to stay within recommended API limits.

FAQ

How do daily XML feed imports interact with real-time API patches?
The daily XML import establishes the complete catalog baseline, while API patch endpoints apply immediate incremental updates for dynamic attributes between bulk imports.
What occurs if an item patched via API is missing from the subsequent daily XML feed?
If an item is omitted from the daily XML import, Tweakwise processes the daily feed as the baseline source of truth, which may cause the item to be treated as unlisted or removed depending on your import configuration.
Where can I find endpoint documentation for backend API patch requests?
