Royal Mail OBA is bring-your-own — connect your account and ship Tracked 24, Tracked 48, Signed For, and International Tracked at your contract rate. Skip the portal logins, the manual address re-typing, the per-parcel manifest reconciliation.
Once your OBA credentials are in /carriers, every Tracked + Signed For + International product flows through Shipnest with the right customs forms attached.
All your OBA products quoted in parallel with whatever else you have connected. Service codes resolve to human names so the picker in /returns shows 'Tracked 24' instead of 'TRK24'.
International Tracked + Signed, International Tracked, International Signed — all priced. CN22 / CN23 customs forms ride on the service code, so the carrier-side process is identical to Click & Drop's.
Per-line HS code + origin + value pre-filled from your product catalog. EORI auto-stamped on EU lanes; IOSS handling for ≤€150 orders to EU buyers.
Signature options map to Royal Mail's `enhancements` array — SIGNED_FOR for standard signature, AGE_RESTRICTED for 18+ products (knives, alcohol). Surfaces on the quote with the right surcharge.
Royal Mail tracking events sync via our 30-min polling cron and render on /track/<number> with your shop's logo and brand color. Buyers don't see royalmail.com unless they specifically want to.
Labels billed to your OBA account at your contracted pricing. Shipnest takes zero relay margin — we charge for the platform layer only.
If you don't already have an OBA account, contact Royal Mail Business sales. Existing OBA customers can request Shipping API access through your account manager — you'll receive a Client ID + Secret pair.
Client ID + Client Secret + your OBA Posting Location. We test the connection with a real rate request before saving, so you know the credentials work the moment they're stored.
/settings/customs → paste your GB EORI + (if applicable) VAT + IOSS. Every future International Tracked + Signed label gets the right paperwork attached automatically. No per-order customs form to fill in.
Every order quotes Royal Mail alongside your other carriers. Buy any service from Tracked 24 to International Tracked + Signed; PDF arrives inline with customs declaration pre-filled.
Royal Mail OBA contracts forbid resale, so we'll never offer operator-side rates here — you'll always connect your own account. Once you have, the rest is automated: customs, tracking, returns + branded tracking page all work as expected.
Paste your OBA credentials once, set up your EORI in /settings/customs, and every Tracked + International label after that prints from inside Shipnest with customs cleared for you.
