What it takes to connect it to your AI chat with Hypamoon, with sources." url: https://hypamoon.com/connect-to/candis --- 1. [Connect to](https://hypamoon.com/connect-to) 2. Candis ERP and accounting # Connect Candis to Hypamoon Possible, with help from Candis. The API is documented, but you cannot just create a key: access goes through Candis first. Possible ## The check Three questions about the API of Candis, answered from its own docs. **Public API docs**\ **Yes.** Public developer portal with the Export, Core Data, Invoice Data and Reimbursement APIs. [Read the docs](https://developer.candis.io) **A key you create yourself**\ **No.** You generate OAuth credentials under Settings, Candis API, but the APIs are tied to the Plus or Max package and are switched on through Candis support. [hilfe.candis.io](https://hilfe.candis.io/en/articles/258724-candis-integration-api-what-can-you-do-with-it) **Versions or a changelog**\ **Yes.** Versioned paths (/v1) and a changelog on the developer portal. [developer.candis.io](https://developer.candis.io) **How it signs in**\ OAuth 2.0 authorization code flow with a client ID and secret you generate in Candis; access tokens are renewed with a refresh token. **Webhooks**\ **Not confirmed.** **Hosting**\ Cloud **Condition**\ Export and Core Data APIs from the Plus package, Invoice Data API in the Max package; switched on through Candis support. ## Your own spend overview on Candis, for the managers who approve. - Approved invoices, postings, cost centres and suppliers through the Candis APIs. - AI that spots unusual amounts per supplier or cost centre. - A screen for budget holders and a monthly email for you. ### Ask your chat Answers straight from your Candis data, in Claude or another chat with the full Hypamoon connection. - Which cost centres spent more this month than last month? - Which suppliers did we pay most this quarter? ### On a schedule Candis has no webhooks we could confirm, so an agent checks every 15 minutes and decides what happens next. 1. Every 15 minutes New approved invoices in a Candis export. AI decides AI compares each amount with earlier invoices from the same supplier. Then Finance gets one email with the invoices that look unusual. ### A screen for your team or customers An app on your own address, with sign-in, on top of the same Candis data. - For your team Budget holders sign in and see spend on their own cost centres. Candis stays the core: your chat builds the rest on its API, as an adapter plus an app and agents in your Hypamoon project. Reading starts after you click Allow in the portal. Every change an agent or a chat makes in Candis waits for your approval, one call at a time. [How adapters work](https://hypamoon.com/docs/adapters) ### Good to know - Candis signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Candis takes more work: ask your chat to check this first. - The export works asynchronously: create an export, wait for it, then fetch the postings. ## Try it in your chat First get access from Candis. Then fill in what to read and write, and send it. Say this in your chat > Build the Hypamoon recipe build-an-adapter for Candis. API docs: https://developer.candis.io. Read: \[what\]. Write: \[what, or nothing\]. [Open in Claude](https://claude.ai/new?q=Build%20the%20Hypamoon%20recipe%20build-an-adapter%20for%20Candis.%20API%20docs%3A%20https%3A%2F%2Fdeveloper.candis.io.%20Read%3A%20%5Bwhat%5D.%20Write%3A%20%5Bwhat%2C%20or%20nothing%5D.) In Claude, or another chat with the full Hypamoon connection; adapters are not in ChatGPT yet. You paste the key in the portal, never in the chat.
