PostNL + ReturnMate

What the PostNL connection actually does.

• NL domestic and EU parcel labels via the PostNL API
• Standard, signature-on-delivery, and EU parcel products
• Automatic 3S barcode generation and label confirmation in one flow
• Multi-parcel shipments — one label per parcel under a shared reference
• Event-level tracking sync mapped onto the RMA timeline
• Label PDFs served straight into the portal and admin

Where it earns its place.

How PostNL gets connected.

Carrier accounts are set up by our team, not by you. We contact PostNL directly, obtain API access against your existing commercial account, and apply it — so you never have to source or handle API credentials.

1. You send us three things

   Your existing PostNL account number, written authority for ReturnMate to contact them on your behalf, and your account manager's name, email and phone number.

2. We contact PostNL

   Our support team requests API access against your account and handles the paperwork and technical back-and-forth with the carrier.

3. We apply the credentials

   Credentials are stored encrypted against your shop. They are never shown to you and never need to be — there is nothing for you to paste or maintain.

4. We test it end to end

   We generate a test label — including the dangerous goods transport document where it applies — and confirm it works before the carrier goes live for your team.

Turnaround varies by carrier, depending on how quickly they issue API access. Support confirms the expected timeline for PostNL when you start onboarding. Don't have an account with them yet? We can help you set one up.
