Webhook — A server-to-server push — the carrier POSTs status changes to your endpoint instead of you polling. HMAC-signed so you can verify it's really them.

Why it matters to your store

Webhooks are what make tracking 'live' — status flows to your store the moment the courier scans, not on a cron delay.

This is the vocabulary every courier invoice, NDR report and rate card is written in — learn it once, save money forever.

Worked example

Courier fires status webhook → Pakka Parcel verifies the signature → order status updates → customer gets the shipping email.

The bottom line

Shipping jargon is really just the billing manual in disguise — every term on this list maps to a line on an invoice or a lever on your margins. Pakka Parcel is built so you rarely have to think about it: statuses normalise, bills reconcile, and quotes already include the surcharges.
