Integrate Expensify Into Your Product Without an API
The Integration Barrier
Expensify has an API, but using it requires developer effort to implement authentication, handle rate limits, and build the data pipeline from Expensify into your product. For accounting platforms, ERP tools, and finance products that need expense data, this is a recurring cost — both upfront in development time and ongoing in maintenance. Deck pulls structured Expensify data for your product without any API setup or developer investment.

FAQ
Does Expensify have a public API?
Yes. The API exists, but using it means your team builds the authentication layer, writes against Expensify’s schema, and keeps the integration current over time. Deck removes all three of those costs.
What Expensify data can Deck extract?
Expense reports with category breakdowns and approval status, individual receipts and attached images, reimbursement status, per-diem and mileage entries, policy violations, and spend totals by employee or department.
Can Deck pull Expensify data for multiple customer accounts?
Yes. Every Expensify account is an independent session in Deck. Volume of customers doesn’t change how your product interfaces with the API.
How does Deck handle Expensify’s authentication?
Credentials go into Deck Vault, where they’re encrypted. MFA is resolved at login automatically — no human involvement after initial setup.
Can I trigger Deck to pull Expensify data when a new report is submitted?
Yes. Deck supports on-demand triggering from your application, so you can kick off a data pull the moment a new report event fires in your system.
