With sources." url: https://hypamoon.com/connect-to/kashflow --- 1. [Connect to](https://hypamoon.com/connect-to) 2. KashFlow ERP and accounting # Connect KashFlow to Hypamoon We could not confirm it. KashFlow 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 KashFlow, answered from its own docs. **Public API docs**\ **Yes.** The SOAP API is documented on KashFlow's developer pages. [Read the docs](https://www.kashflow.com/developers/) **A key you create yourself**\ **Yes.** Switch the API on yourself under Apps, API Settings; you can limit it to IP addresses. [kashflow.com](https://www.kashflow.com/developers/enable-api/) **Versions or a changelog**\ **Not confirmed.** No API version or API changelog found. **How it signs in**\ The API is switched on in your account under Apps, API Settings, optionally limited to IP addresses; the login method was not confirmed. **Webhooks**\ **Not confirmed.** **Hosting**\ Cloud **Condition**\ The API is free on the KashFlow Business package. ## In practice What it takes in a real KashFlow administration. **Getting access**\ Tick the API box under Apps, API Settings in KashFlow, and optionally limit access to IP addresses. **Limits**\ None published. **Writing**\ **Not confirmed.** **Cost**\ Free for users on the Business package. [kashflow.com](https://www.kashflow.com/developers/enable-api/) ## What you can build Create invoices and customers in KashFlow from your own order flow, through the SOAP API. 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 - KashFlow only documents a SOAP API. It is free for users on the Business package. ## Try it in your chat First get access from KashFlow. Then fill in what to read and write, and send it. Say this in your chat > Build the Hypamoon recipe build-an-adapter for KashFlow. API docs: https://www.kashflow.com/developers/soap-api/. Read: \[what\]. Write: \[what, or nothing\].
