Authentication

Royal Mail API client ID X-IBM-Client-Id: <credential> + Royal Mail API client ID X-IBM-Client-Secret: <credential> discovered

Royal Mail API client ID api_key Get key ↗

Create an account in the Royal Mail API Portal. In My Apps, register your application; Royal Mail assigns a client ID and client secret. To use Shipping, Tracking, or Local Collect APIs, Royal Mail says you may need your account manager to initiate the integration and some API subscriptions require approval.

Royal Mail API client ID X-IBM-Client-Id: <credential> + Royal Mail API bearer token Authorization: Bearer <credential> discovered

Royal Mail API bearer token oauth2 Set up OAuth ↗

For APIs that support bearer auth, first create a Royal Mail API Portal account and register an app in My Apps to obtain the client credentials Royal Mail uses for subscriptions. The Delivery Office Finder API page shows an OAuth2 password flow and a token URL template (deployment-specific), but the public docs do not provide a concrete production token endpoint or end-user steps on the scraped page.
