PostNL Shops and shipping # Connect PostNL to Hypamoon Yes. PostNL has a public, versioned API and you create the key yourself, so your chat can write the adapter. Open ## The check Three questions about the API of PostNL, answered from its own docs. **Public API docs**\ **Yes.** [Read the docs](https://developer.postnl.nl/docs/) **A key you create yourself**\ **Yes.** Business customers create API keys in Mijn PostNL Zakelijk under My Account, API Management. [developer.postnl.nl](https://developer.postnl.nl/integration-with-postnl/request-api-key/) **Versions or a changelog**\ **Yes.** Versioned APIs such as Shipment V4 and a public changelog. [developer.postnl.nl](https://developer.postnl.nl/operational-status/changelog/) **How it signs in**\ API key sent in the apikey header, created in your Mijn PostNL Zakelijk account. **Webhooks**\ **Yes.** It can tell your app when something changes. [postnl.nl](https://www.postnl.nl/api/assets/blt43aa441bfc1e29f2/bltc95e471d26d81c25/69bbd1ec6489cb823a37ddcc/questions-and-answers-renewed-apis-and-it-integrations-eng-19032026.pdf) **Hosting**\ Cloud **Condition**\ Needs a PostNL business customer account. ## What you can build Create shipping labels from your own order flow, check addresses and delivery options at checkout, and follow parcels without logging in. Your chat writes it as a Hypamoon adapter from the docs above. Reading starts after you click Allow in the portal, and every write waits for your approval, one call at a time. [How adapters work](https://hypamoon.com/docs/adapters) ### Good to know - Your adapter uses a fixed key: you paste it once in the Hypamoon portal, never in the chat, and it only goes to the API host you allow. - Track and trace updates can be pushed through the Tracking Webhook, or fetched with the Shipping Status API. New developer test keys are no longer issued. ## Try it in your chat Fill in what to read and write, and send it. Say this in your chat > Build the Hypamoon recipe build-an-adapter for PostNL. API docs: https://developer.postnl.nl/docs/. Read: \[what\]. Write: \[what, or nothing\].

Ask the chat to check its API. The same three checks work for any software. Your chat reads the vendor's own docs and tells you what it found. Say this in your chat > Check if \[software\] has an open API that a Hypamoon adapter can use: public API docs, a key or token I can create myself without asking the vendor, and versions or a changelog.
