The Zoho Expense API is a REST-based interface that allows developers and IT teams to interact programmatically with Zoho Expense data. You can use it to create expenses from external systems, retrieve expense reports for custom reporting, push reimbursement statuses from a payroll system, or build custom integrations with ERP or travel booking platforms that are not natively supported by Zoho Expense.
The Zoho Expense API supports operations on core entities including expenses, expense reports, advances, trips, and employees. Common use cases include: auto-creating expense entries from credit card transaction webhooks, syncing approved reimbursement data to a custom payroll system, pulling expense data into a business intelligence tool, and creating custom approval workflows in an external system that triggers status updates in Zoho Expense via the API.
The Zoho Expense API uses OAuth 2.0 for authentication. Developers register an application in the Zoho API Console, obtain client credentials, and exchange them for access tokens. The API is rate-limited, and detailed documentation with endpoint references, request/response examples, and error codes is available in the Zoho Expense developer documentation.
Yes. The API’s POST /expenses endpoint accepts individual expense payloads, and you can call it iteratively or in batches to migrate historical expense data from a legacy system into Zoho Expense. For very large datasets, Zoho also supports bulk import via CSV, which may be faster than API calls for one-time migrations.
No separate developer account is needed. You register your API application in the Zoho API Console using your existing Zoho account. API access uses the permissions of the authenticated user, so the OAuth token you generate will have the same Zoho Expense access rights as that user account.
