What we could and could not confirm about its API, with sources." url: https://hypamoon.com/connect-to/yuki --- 1. [Connect to](https://hypamoon.com/connect-to) 2. Yuki (Nmbrs Accounting) ERP and accounting # Connect Yuki (Nmbrs Accounting) to Hypamoon We could not confirm it. Yuki (Nmbrs Accounting) passes some of our checks, but not all three could be confirmed from its own docs. Unknown ## The check Three questions about the API of Yuki (Nmbrs Accounting), answered from its own docs. **Public API docs**\ **Yes.** The SOAP web services and their methods are publicly listed. [Read the docs](https://api.yukiworks.nl/ws/Accounting.asmx) **A key you create yourself**\ **Yes.** A user with the Portal administrator or Management role creates a web service API key. [support.yuki.nl](https://support.yuki.nl/en/support/solutions/articles/80000787231-web-service-access-code-web-service-api-key-webserviceaccesskey-) **Versions or a changelog**\ **Not confirmed.** No API versions or changelog found. [support.yuki.nl](https://support.yuki.nl/en/support/solutions/articles/80000787670-yuki-api-link) **How it signs in**\ A web service API key that you exchange for a session ID with the Authenticate method. **Webhooks**\ **Not confirmed.** **Hosting**\ Cloud **Condition**\ Each domain gets 1,000 web service calls per day; more calls need a paid accountant feature. In the Minimal bundle the Sales web service is a paid extra. ## In practice What it takes in a real Yuki (Nmbrs Accounting) administration. **Getting access**\ A user with the Portal administrator or Management role creates a web service API key in Nmbrs Accounting (Yuki) and notes the administration ID; the integration logs in with that key. **Limits**\ 1,000 web service calls per day per domain for free; the paid Webservice feature raises this to 5,000 and Webservice Extended to 10,000 calls per day. [support.yuki.nl](https://support.yuki.nl/en/support/solutions/articles/80000787670-yuki-api-link) **Writing**\ **Read and write.** Add journal entries, sales invoices, petty cash transactions, documents, contacts and projects; the Purchase service needs a formal request and an extra client ID and secret. **Cost**\ More than 1,000 calls a day needs a paid Webservice feature, and in the Minimal bundle the Sales web service is a paid extra; prices are not published on that page.

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. - Yuki is now called Nmbrs Accounting. The API is SOAP with XML, and the endpoint depends on your country (api.yukiworks.nl or api.yukiworks.be). ## Try it in your chat First get access from Yuki (Nmbrs Accounting). Then fill in what to read and write, and send it. Say this in your chat > Build the Hypamoon recipe build-an-adapter for Yuki (Nmbrs Accounting). API docs: https://support.yuki.nl/en/support/solutions/articles/80000787670-yuki-api-link. Read: \[what\]. Write: \[what, or nothing\].
