What your AI chat can build with it on Hypamoon, how it connects, and the sources we checked." url: https://hypamoon.com/connect-to/zoho-expense --- 1. [Connect to](https://hypamoon.com/connect-to) 2. Zoho Expense ERP and accounting # Connect Zoho Expense to Hypamoon Yes, with one catch. Zoho Expense has an open API that you can use yourself, but it signs in with OAuth only, and that takes more work in a Hypamoon adapter today. Open ## The check Three questions about the API of Zoho Expense, answered from its own docs. **Public API docs**\ **Yes.** [Read the docs](https://www.zoho.com/expense/api/v1/introduction/) **A key you create yourself**\ **Yes.** You register a Self Client in the Zoho API console with your Zoho Expense login and get a client ID and secret. [zoho.com](https://www.zoho.com/expense/api/v1/oauth/) **Versions or a changelog**\ **Yes.** Versioned API (v1 in the path). [zoho.com](https://www.zoho.com/expense/api/v1/introduction/) **How it signs in**\ OAuth 2.0 through the Zoho API console; requests carry a Zoho-oauthtoken header and an organization ID. **Webhooks**\ **Not confirmed.** **Hosting**\ Cloud ## Your own expense overview on Zoho Expense, built around how your team travels and spends. - Expense reports, expenses, trips and users, through the scopes you allow. - AI that checks reports against your policy and suggests what to ask, with a person approving. - A screen for managers and a weekly email for finance. ### Ask your chat Answers straight from your Zoho Expense data, in Claude or another chat with the full Hypamoon connection. - Which expense reports have been waiting for approval for more than a week? - Which employees spent the most on travel this quarter? ### On a schedule Zoho Expense has no webhooks we could confirm, so an agent checks every 15 minutes and decides what happens next. 1. Every 15 minutes New expense reports submitted since the last check. AI decides AI compares each expense with your policy and earlier reports. Then The approver gets an email with what looks fine and what needs a question. ### A screen for your team or customers An app on your own address, with sign-in, on top of the same Zoho Expense data. - For your team Managers see open reports from their team and the total per project. Zoho Expense 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 Zoho Expense waits for your approval, one call at a time. [How adapters work](https://hypamoon.com/docs/adapters) ### Good to know - Zoho Expense signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Zoho Expense takes more work: ask your chat to check this first. - 100 requests per minute per organization, and 1,000 to 10,000 requests per day depending on the plan. Use the API domain of your Zoho data center. ## Try it in your chat Fill in what to read and write, and send it. Say this in your chat > Build the Hypamoon recipe build-an-adapter for Zoho Expense.
