Expensify ERP and accounting # Connect Expensify to Hypamoon Possible, with help from Expensify. The API is documented, but you cannot just create a key: access goes through Expensify first. Possible ## The check Three questions about the API of Expensify, answered from its own docs. **Public API docs**\ **Yes.** [Read the docs](https://integrations.expensify.com/Integration-Server/doc/) **A key you create yourself**\ **Yes.** Any Expensify account can generate a partnerUserID and partnerUserSecret on the integrations page. Creating reports and expenses needs extra permission from Expensify. [integrations.expensify.com](https://integrations.expensify.com/Integration-Server/doc/) **Versions or a changelog**\ **No.** No version numbers or changelog in the Integration Server docs. [integrations.expensify.com](https://integrations.expensify.com/Integration-Server/doc/) **How it signs in**\ partnerUserID and partnerUserSecret sent in each request; they are shown only once. **Webhooks**\ **Not confirmed.** **Hosting**\ Cloud **Condition**\ Creating reports must be enabled by Expensify Concierge, and creating expenses needs advanced permissions requested from Expensify. ## What you can build Export approved reports for bookkeeping, keep policy categories and tags in step with your ledger, and update employee records. 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. - Limits are 5 requests per 10 seconds and 20 per minute. Report export works through templates and a separate download call. ## Try it in your chat First get access from Expensify. Then fill in what to read and write, and send it. Say this in your chat > Build the Hypamoon recipe build-an-adapter for Expensify. API docs: https://integrations.expensify.com/Integration-Server/doc/. Read: \[what\]. Write: \[what, or nothing\].
