What this covers

This section explains how APIs and EDI deliver commerce data. An API is a software interface that shares live product and stock data. EDI means Electronic Data Interchange. EDI sends standard order and delivery documents. Both affect the follow‑up costs households may face.

API provides real‑time inventory and status updates.
EDI transmits structured order and shipping records.
Missing or delayed messages often create extra work.

Which data to check: Check availability and lead time in the product feed. These fields show expected delivery or pickup timing. Compare dimensions, weight and return rules. Incorrect measures cause failed pickups or extra transport costs.

Availability: in stock, reserved, restock date.
Lead time in days and any buffer periods.
Package dimensions and net weight.

Orders and status messages: Ask for a clear confirmation with status codes. Status codes summarise the shipping steps and reduce questions. Watch for automated updates. A missing dispatch note can delay problem resolution and create calls or trips.

Order received, picking, shipped, delivered.
Use tracking numbers and check them early.
For pickup: reservation window and pick‑up location.

Handling errors simply: Clarify how the seller reports and fixes errors. A fixed communication path saves you time and travel. Request standard proofs for issues. A photo or short video usually documents damage or wrong parts well.

Name the problem type: damaged, wrong item, missing parts.
Set a claim window, often 24–72 hours after receipt.
Agree on contact channels: email, phone or local pickup point.

Use automation wisely: Automate repetitive steps only. For example, automatic stock updates by API cut manual checks and reduce errors. Enable alerts for exceptions. A stock gap alert stops you from making a futile trip for pickup.

Auto‑reserve on payment receipt.
Real‑time feed for local availability.
Keep manual checks for bulky items and special orders.

Shipping or pickup
