Why integrate with Brex
Common scenarios for SaaS companies building Brex integrations for their customers.
Automate employee card provisioning from your HR platform
HR and onboarding SaaS companies can sync employee lifecycle events to Brex, automatically provisioning corporate cards for new hires and revoking access on termination — eliminating manual finance work.
Enrich financial dashboards with real-time Brex spend data
FinOps and analytics platforms can pull transaction and balance data from Brex to give CFOs a unified cash-flow view alongside other financial data sources, without requiring Brex admin credentials.
Sync user directories to keep Brex rosters accurate
Any SaaS product managing employee identity or org structure can use Truto's Unified User Directory API to read and sync user data with Brex, ensuring departments, roles, and access stay consistent across systems.
Close the loop on procurement approvals with virtual cards
Procurement and spend management platforms can trigger virtual card creation in Brex after a purchase is approved, tying each card to a specific vendor and budget to eliminate shadow spending.
Automate expense reconciliation from booking platforms
Travel and booking SaaS products can match transactions in Brex and attach receipts or itineraries programmatically, removing the need for employees to manually submit expense reports.

How It Works
From zero to integrated
Go live with Brex in under an hour. No boilerplate, no maintenance burden.
Link your customer’s Brex account
Use Truto’s frontend SDK to connect your customer’s Brex account. We handle all OAuth and API key flows — you don’t need to create the OAuth app.
We handle authentication
Don’t spend time refreshing access tokens or figuring out secure storage. We handle it and inject credentials into every API request.
Call our API, we call Brex
Truto’s Proxy API is a 1-to-1 mapping of the Brex API. You call us, we call Brex, and pass the response back in the same cycle.
Unified response format
Every response follows a single format across all integrations. We translate Brex’s pagination into unified cursor-based pagination. Data is always in the result attribute.
FAQs
Common questions about Brex on Truto
Authentication, rate limits, data freshness, and everything else you need to know before you integrate.
What Unified APIs does Truto support for Brex today?
Truto supports Brex through the Unified User Directory API, which covers reading and syncing user (employee) data. Additional tools and Unified API coverage can be built on request based on your use case.
How does authentication work for Brex through Truto?
Brex uses OAuth 2.0 for API access. Truto manages the full auth flow — token exchange, refresh, and storage — so your end users can connect their Brex accounts without you handling credentials directly.
Can I access Brex transactions or expense data through Truto?
Brex's API supports transactions, expenses, budgets, and payments endpoints. These are not yet mapped to a Truto Unified API out of the box, but Truto can build custom tools and proxy access on request to cover these use cases.
Does Truto handle pagination and rate limits for the Brex API?
Yes. Truto abstracts away pagination logic and respects Brex's rate limits automatically, so you get consistent data fetching behavior without writing API-specific retry or cursor management code.
What user data can I read from Brex via the Unified User Directory API?
You can read standard user directory fields such as name, email, department, role, and employment status. Truto normalizes these into a unified schema so you can work with Brex user data the same way you work with any other connected directory.
Can I write data back to Brex or is it read-only?
Brex's API supports both read and write operations across many endpoints including user creation and card management. Write support through Truto depends on the specific Unified API and tools available — contact Truto to confirm write capabilities for your use case.
