Integrate Brex Into Your Product Without an API

The Integration Barrier

Brex has a developer API, but integrating it into your product requires OAuth 2.0 implementation, developer time to build the data pipeline, and ongoing maintenance. For finance or accounting products that need Brex card transactions, spend data, or statements flowing into their platform, the development overhead — multiplied across every customer using Brex — can be substantial. Deck gives you a single endpoint to pull structured Brex data for any connected customer account.

Workflows Deck Supports

  1. Pull card transaction records and deliver them to your expense categorization or accounting product
  2. Extract receipts and attached documents and surface them in your document management layer
  3. Pull monthly statements and deliver them to your finance reporting tool
  4. Extract vendor spend totals and surface them in your procurement analytics product
  5. Pull budget allocation and utilization data and keep your spend dashboard current
  6. Extract reimbursement records and sync them to your finance workflow platform

FAQ

Does Brex have a public API?

Yes. But standing up a production Brex integration requires OAuth implementation, token refresh logic, schema mapping, and ongoing upkeep. Deck is a faster path to the same data.

What Brex data can Deck extract?

Card transactions, attached receipts, monthly statements, vendor spend totals broken out by category, budget allocation and utilization, and reimbursement records.

Can Deck pull Brex data for multiple customer companies?

Each company’s Brex account is a separate session in Deck. Your product calls one endpoint with an account ID and gets back that company’s data.

How does Deck handle Brex’s MFA?

Deck Vault resolves authentication steps — including MFA — at runtime. Sessions run fully automated after initial credential setup.

Is Brex financial data secure with Deck?

Credentials are encrypted in Deck Vault from the moment they’re stored. Extracted data is delivered to your endpoint and not held on Deck’s side after that.
