Steps
Register for an InPost UK account and request API access/token from your InPost UK account manager (the developer portal at developers.inpost.co.uk requires an authenticated login to view full reference docs).
Authenticate using the retailer token as a Bearer token in the Authorization header.
Look up the destination locker's point code via InPost's point lookup / Geowidget.
Create a shipment against the InPost UK API v4 base URL (https://api-uk.easypack24.net/v4/), specifying the target locker point and service type.
Call the Pay/label resource to move the parcel from 'Created' to 'Prepared' status and retrieve the printable label.
Track lifecycle via status polling (Created → Prepared → Sent → InTransit → Stored → Delivered).
Known gotchas
InPost UK's v4 API (api-uk.easypack24.net) is a distinct, older REST API from InPost's newer global ShipX/developers.inpost-group.com OAuth2.1 platform — confirm which one your account is provisioned on before coding.
The developers.inpost.co.uk portal requires login to view full docs; a public Postman collection covers the general request/response shape but may lag the authenticated reference.
Locker sizes are fixed to three tiers (A/B/C, up to 41x38x64cm); oversized items will be rejected at label creation.
