Visma.net ERP ERP and accounting # Connect Visma.net ERP to Hypamoon Possible, with help from Visma.net ERP. The API is documented, but you cannot just create a key: access goes through Visma.net ERP first. Possible ## The check Three questions about the API of Visma.net ERP, answered from its own docs. **Public API docs**\ **Yes.** Swagger documentation and guides are public. [Read the docs](https://community.visma.com/t5/Knowledge-base-in-Developers/tkb-p/DV_CO_Vismanet_knowledgebase) **A key you create yourself**\ **No.** You register the app yourself in the Visma Developer Portal, but an API integration can need approval by the Visma API team, and the customer must approve it in the Visma App Store. [docs.connect.visma.com](https://docs.connect.visma.com/docs/add-an-api-integration) **Versions or a changelog**\ **Yes.** Release notes per API version. [community.visma.com](https://community.visma.com/t5/News-in-Developers-Visma-net/bg-p/DV_CO_Vismanet_news/label-name/Release-notes) **How it signs in**\ OAuth 2.0 through Visma Connect; server integrations use client credentials with the customer's tenant ID, and tokens last at most 60 minutes. **Webhooks**\ **Yes.** It can tell your app when something changes. [community.visma.com](https://community.visma.com/t5/News-in-Developers-Visma-net/bg-p/DV_CO_Vismanet_news/label-name/Release-notes) **Hosting**\ Cloud **Condition**\ An API integration may need approval by Visma, and the customer approves it in the Visma App Store. ## In practice What it takes in a real Visma.net ERP administration. **Getting access**\ The developer registers the app in the Visma Developer Portal and asks for the ERP API scopes (some need approval by the Visma API team); the customer's administrator then approves the integration in the Visma App Store for their company. **Limits**\ Visma's knowledge base gives 15,000 calls per hour per company for production clients and 500 per hour per company for test clients, plus at most 5 identical requests per minute. [community.visma.com](https://community.visma.com/t5/Knowledge-base-in-Developers/Why-am-I-receiving-quot-HTTP-429-Too-many-request-throttling/ta-p/271133) **Writing**\ **Read and write.** Create and update customers and sales orders, and create invoices, through the REST API. **Cost**\ Not published. ## What you can build A customer portal that places sales orders straight in Visma.net and shows the order status, and a chat check on open invoices per customer. 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 - Visma.net ERP signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Visma.net ERP takes more work: ask your chat to check this first. - Webhook subscriptions are managed in the Visma Developer Portal. ## Try it in your chat First get access from Visma.net ERP. Then fill in what to read and write, and send it. Say this in your chat > Build the Hypamoon recipe build-an-adapter for Visma.net ERP.
