What it takes to connect it to Hypamoon, with sources." url: https://hypamoon.com/connect-to/snelstart --- 1. [Connect to](https://hypamoon.com/connect-to) 2. SnelStart ERP and accounting # Connect SnelStart to Hypamoon Possible, with help from SnelStart. There is an API, but the docs or the key only come after you ask SnelStart for access. Possible ## The check Three questions about the API of SnelStart, answered from its own docs. **Public API docs**\ **No.** The API reference is only visible after you create a free account on the developer portal. [Read the docs](https://b2bapi-developer.snelstart.nl/) **A key you create yourself**\ **No.** You apply through a form to get a development key; a permanent key comes only after SnelStart certifies the integration. SnelStart reviews every request. [snelstart.nl](https://www.snelstart.nl/api) **Versions or a changelog**\ **Not confirmed.** Could not see versioning without an account. [b2bapi-developer.snelstart.nl](https://b2bapi-developer.snelstart.nl/) **How it signs in**\ A subscription key from the developer portal plus an access token; production integrations must use OAuth. **Webhooks**\ **Not confirmed.** **Hosting**\ Cloud **Condition**\ Needs an application and certification by SnelStart before you get a permanent key. ## In practice What it takes in a real SnelStart administration. **Getting access**\ The developer applies to SnelStart through the form on snelstart.nl/api and gets a development key; after certification the administration owner signs in to SnelStart Web, opens the integration tile and generates a link key to paste into the integration. **Limits**\ None published. **Writing**\ **Not confirmed.** The API reference is only visible after creating a developer account, so what you can write is not confirmed here. **Cost**\ A one time fee of 250 euro (excl. VAT) per permanent key, charged after certification and approval.

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. - SnelStart says it is careful about admitting new production integrations, so approval can take a while. ## Try it in your chat First get access from SnelStart. Then fill in what to read and write, and send it. Say this in your chat > Build the Hypamoon recipe build-an-adapter for SnelStart. API docs: https://b2bapi-developer.snelstart.nl/. 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.
