Visma eAccounting ERP and accounting # Connect Visma eAccounting to Hypamoon Possible, with help from Visma eAccounting. The API is documented, but you cannot just create a key: access goes through Visma eAccounting first. Possible ## The check Three questions about the API of Visma eAccounting, answered from its own docs. **Public API docs**\ **Yes.** [Read the docs](https://developer.vismaonline.com/docs/spiris-eaccounting-api-documentation) **A key you create yourself**\ **No.** You must register as a partner to get credentials and a sandbox; production access is granted on request by API support. [developer.vismaonline.com](https://developer.vismaonline.com/docs/spiris-eaccounting-api-documentation) **Versions or a changelog**\ **Yes.** Version 2 in the URL and a dated changelog. [developer.vismaonline.com](https://developer.vismaonline.com/changelog) **How it signs in**\ OAuth 2.0 through the Visma identity server; access tokens last 60 minutes and refresh tokens two years. **Webhooks**\ **Not confirmed.** **Hosting**\ Cloud **Condition**\ Needs partner registration, and production access is granted on request. ## In practice What it takes in a real Visma eAccounting administration. **Getting access**\ The developer registers in the Visma (Spiris) partner programme to get a client ID and sandbox, asks API support for production access, and the customer then signs in once with Visma to approve the app. **Limits**\ 600 requests per minute per client and per endpoint; over the limit you get HTTP 429. [developer.vismaonline.com](https://developer.vismaonline.com/docs/rate-limits-copy.md) **Writing**\ **Read and write.** Create and update customers and create customer invoice drafts. **Cost**\ Visma's Dutch partner page says the API is free to use, with no limit on the number of integrations. [nl.visma.com](https://nl.visma.com/eaccounting/partners/) ## What you can build Create the customer and a draft invoice in eAccounting as soon as a job is marked done in your planning tool, so the invoice is ready to check and send. 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 eAccounting 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 eAccounting takes more work: ask your chat to check this first. - Limit of 600 requests per minute per client and endpoint. The developer docs now use the name Spiris. ## Try it in your chat First get access from Visma eAccounting. Then fill in what to read and write, and send it.
