Ramp's REST API enables programmatic control of corporate cards, spend limits, expense approvals, reimbursements, and accounting sync — purpose-built for finance automation and spend management at scale.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
OAuth 2.0 with fine-grained scopes. PCI-DSS compliant. SOC 2 Type II. Card data never returned in full — PAN masked. Webhook HMAC signatures for payload validation.
⚡ Reliability
Best When
Your company uses Ramp for corporate spend and you need agents to issue cards, set limits, or sync expenses to your accounting stack automatically.
Avoid When
You need global card issuance or are outside the US — Brex or Airwallex may have better international coverage.
Use Cases
- • Automatically issuing virtual cards with custom spend limits for agent-driven procurement
- • Syncing Ramp transactions and categorizations to accounting systems (QuickBooks, NetSuite)
- • Monitoring and enforcing spend policies from automated finance workflows
- • Processing expense reimbursements and approvals without manual review
- • Building real-time spend dashboards with Ramp transaction webhook data
Not For
- • Consumer expense tracking (Ramp is B2B corporate cards only)
- • International cards in all geographies (Ramp is US-centric)
- • Companies needing physical card programs before virtual card approval
Interface
Authentication
OAuth 2.0 client credentials for server-to-server. Scopes map to specific resource operations (transactions:read, cards:write, users:read). Access tokens expire in 1 hour. Requires Ramp Business account with developer access enabled.
Pricing
Ramp's platform is free because they earn interchange on card spend. API access is included. Apply for a Ramp business account to get API credentials.
Agent Metadata
Known Gotchas
- ⚠ OAuth scopes are narrow — agents must request specific scopes at authorization time; cannot add scopes without re-auth
- ⚠ Virtual card creation requires a spending entity — agents must know the department/entity ID before issuing cards
- ⚠ Access tokens expire in 1 hour — agents in long-running workflows must refresh proactively
- ⚠ Ramp is US-only — attempting to create cards for non-US entities fails silently or returns confusing errors
- ⚠ Webhook events for spend require signature validation — missed validation is a fraud risk in financial workflows
