[Connect to](https://hypamoon.com/connect-to) 2. Microsoft Dynamics 365 Business Central ERP and accounting # Connect Microsoft Dynamics 365 Business Central to Hypamoon Yes. Microsoft Dynamics 365 Business Central 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 Microsoft Dynamics 365 Business Central, answered from its own docs. **Public API docs**\ **Yes.** [Read the docs](https://learn.microsoft.com/en-us/dynamics365/business-central/dev-itpro/api-reference/v2.0/) **A key you create yourself**\ **Yes.** You register an app in your own Microsoft Entra ID and allow it in Business Central. [learn.microsoft.com](https://learn.microsoft.com/en-us/dynamics365/business-central/dev-itpro/administration/automation-apis-using-s2s-authentication) **Versions or a changelog**\ **Yes.** Versioned API (v2.0) and a documented list of deprecated features. [learn.microsoft.com](https://learn.microsoft.com/en-us/dynamics365/business-central/dev-itpro/api-reference/v2.0/) **How it signs in**\ OAuth 2.0 through Microsoft Entra ID, including client credentials for unattended integrations. On premises, a web service access key with basic auth is still possible. **Webhooks**\ **Yes.** It can tell your app when something changes. [learn.microsoft.com](https://learn.microsoft.com/en-us/dynamics365/business-central/dev-itpro/api-reference/v2.0/dynamics-subscriptions) **Hosting**\ Cloud and self-hosted ## In practice What it takes in a real Microsoft Dynamics 365 Business Central administration. **Getting access**\ Your IT administrator registers an app in your own Microsoft Entra ID with API permissions, then adds it on the Microsoft Entra Applications page in Business Central and gives it permission sets. **Limits**\ Online, per user or app: 6,000 OData or API requests per 5 minutes, 5 processed at the same time and 100 connections including queued ones; at most 20,000 records per page and 8 minutes per request. Over the limit you get HTTP 429. [learn.microsoft.com](https://learn.microsoft.com/en-us/dynamics365/business-central/dev-itpro/administration/operational-limits-online) **Writing**\ **Read and write.** Create and update customers, items, sales orders, sales invoices, journals and more through the standard v2.0 API; extra fields need a custom API page. **Cost**\ No licence is needed for a service to service app with client credentials; with delegated sign in or basic auth the calls run as a licensed user. [learn.microsoft.com](https://learn.microsoft.com/en-us/dynamics365/business-central/dev-itpro/webservices/web-services-authentication) ## What you can build A web shop or intake form that creates customers and sales orders straight in Business Central, and a chat answer on stock and 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 - 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. - For Business Central on premises, your server must be reachable from the internet over HTTPS, and the APIs depend on your installed version and extensions. - Basic auth with web service access keys stopped working online in October 2022. ## Try it in your chat Fill in what to read and write, and send it.
