With sources." url: https://hypamoon.com/connect-to/ifirma --- 1. [Connect to](https://hypamoon.com/connect-to) 2. iFirma ERP and accounting # Connect iFirma to Hypamoon We could not confirm it. iFirma 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 iFirma, answered from its own docs. **Public API docs**\ **Yes.** Public API documentation at api.ifirma.pl, in Polish. [Read the docs](https://api.ifirma.pl/faq) **A key you create yourself**\ **Yes.** Symmetric keys are generated in the API tab of the account configuration; the API is available to users with super account rights. [api.ifirma.pl](https://api.ifirma.pl/niezbe%cc%a8dne-informacje-oraz-wysylanie-z%cc%87a%cc%a8dania/) **Versions or a changelog**\ **Not confirmed.** No versioning or changelog found. **How it signs in**\ Each request carries an HMAC SHA1 signature made with a key from the API tab (one key per area such as invoices or expenses); RSA keys are also supported. **Webhooks**\ **Not confirmed.** **Hosting**\ Cloud ## In practice What it takes in a real iFirma administration. **Getting access**\ A user with super account rights generates keys in the API tab of the account configuration. **Limits**\ None published. **Writing**\ **Read and write.** The documentation has sections for creating sales documents, expenses and contractors; individual endpoints not checked one by one. **Cost**\ Not published. ## What you can build Send invoices and expense documents from your own system into iFirma, so your bookkeeping is complete without typing. 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 - iFirma signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for iFirma takes more work: ask your chat to check this first. - Keys are per area: subscriber, invoice, bill or expense. iFirma has a page to check your API limit. ## Try it in your chat First get access from iFirma. Then fill in what to read and write, and send it. Say this in your chat > Build the Hypamoon recipe build-an-adapter for iFirma. API docs: https://api.ifirma.pl/. Read: \[what\]. Write: \[what, or nothing\].
