Efficy 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 Efficy, answered from its own docs. **Public API docs**\ **Not confirmed.** Efficy offers REST and SOAP APIs according to integrators, but we did not find public Efficy API documentation. [Read the docs](https://www.efficy.com) **A key you create yourself**\ **Not confirmed.** **Versions or a changelog**\ **Not confirmed.** **How it signs in**\ Not confirmed. **Webhooks**\ **Not confirmed.** **Hosting**\ Cloud ## What you can build Not confirmed yet whether you can build your own connection on Efficy. 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.
