BILL Spend & Expense API
BILL Spend & Expense is corporate card and expense management software (formerly Divvy) that helps companies issue physical and virtual cards, set budgets, capture receipts, approve expenses, and sync spending to accounting. An unofficial API lets you pull cards, budgets, transactions
What is BILL Spend & Expense?
BILL Spend & Expense is a cloud platform for corporate card issuing and expense management. Finance teams use it to create budgets, provision physical and virtual cards, enforce spend policies, capture receipts, streamline approvals, reimburse employees, and sync transactions to accounting systems.
Core product areas include:
- Corporate Cards & Budgets (physical/virtual cards, spend limits, budget membership, controls)
- Expense Management & Reimbursements (receipt capture, coding, approvals, ACH reimbursements)
- Policy & Approvals (MCC restrictions, per-transaction limits, rules-based approvals, audit trail)
- Accounting Integrations (GL accounts, departments/classes, vendor mapping, ERP sync for transactions and statements)
- Merchant & Subscription Management (virtual cards for vendors, recurring spend tracking)
Common data entities:
- Companies, Users, Roles/Permissions (Admins, Approvers, Cardholders)
- Budgets (name, limit, period, owner, members, policies)
- Cards (physical/virtual, last4, status, assigned user, budget)
- Transactions (merchant, MCC, amount, auth/posted timestamps, status, currency)
- Expenses (coding: GL account, department/class, memo, custom fields, approval state)
- Receipts & Attachments (images, PDFs, upload tokens, status)
- Reimbursements (non-card expenses, payable to employee, ACH details)
- Merchants (name, MCC, location, recurring indicators)
- Statements & Exports (period totals, CSV/OFX)
The BILL Spend & Expense Integration Challenge
Finance teams rely on BILL Spend & Expense daily, but turning portal-based workflows into API-driven automation is non-trivial:
- Role-aware views: Admins, approvers, and cardholders see different objects, permissions, and approval states
- Policy rigor: Budgets, MCC restrictions, limits, receipts, and multi-step approvals require careful handling and auditability
- Portal-first features: Receipt capture, reimbursements, and approvals are optimized for front-end flows, not headless automation
- Authentication complexity: SSO/MFA and session lifecycles complicate unattended integrations
- Data fragmentation: Key context spans cards, budgets, transactions, expenses, and accounting mappings
- Common complaints: Limited or gated official API access, extra costs for API usage, CSV exports that miss fields or receipt links, lack of webhooks for real-time automation, and difficulty pulling complete receipt images or coding metadata

API Endpoints
Authentication
/sessionsEstablish a session using credentials. Supergood manages MFA (SMS, email, TOTP) and SSO/OAuth when enabled. Returns a short-lived auth token maintained by the platform.
Authentication
/sessions/refreshRefresh an existing token to keep sessions uninterrupted.
Cards
/cardsList corporate cards with filters and summary details.
Transactions
/transactionsRetrieve card transactions with merchant, coding, and receipt metadata.
Expenses
/expenses/{expenseId}Update coding, attach receipts, and manage approvals for an expense.
Budgets
/budgetsCreate a budget with spend limits, membership, and policy controls.
Use Cases
Card, Budget, & User Sync
- Mirror cards, budgets, and users into your internal systems - Keep card assignments and budget membership current for analytics and policy enforcement - Normalize limits, statuses, and MCC controls for multi-entity operations
Expense Coding & Approval Automation
- Auto-code transactions from your rules engine and push updates back to expenses - Trigger approvals, track states, and reconcile with ERP/GL - Attach receipts captured in your product and validate policy compliance
Real-Time Spend Monitoring & Controls
- Stream transactions for anomaly detection and spend alerts - Provision virtual cards programmatically for vendors/subscriptions - Adjust limits or lock cards in response to detected risks
Accounting & ERP Sync
- Map merchants and MCCs to GL accounts, departments, and classes - Push approved, coded transactions to accounting systems (QuickBooks, NetSuite, Xero, Sage Intacct) - Reconcile statements and reimbursement payouts with your ERP

Frequently asked questions
Supergood supports workflows across commonly used modules such as Corporate Cards (physical/virtual), Budgets, Transactions, Expenses/Receipts, and Reimbursements, subject to your licensing and entitlements. We scope coverage during integration assessment.
We support username/password + MFA (SMS, email, TOTP) and can operate behind SSO/OAuth when enabled. Sessions are refreshed automatically with secure challenge handling.
Yes. We can normalize transactions, reimbursements, and coding fields (GL accounts, departments, classes) to match your ERP/accounting schema and deliver updates via webhooks or polling while complying with rate and permission constraints. We commonly integrate with QuickBooks, NetSuite, Xero, and Sage Intacct.
Yes. We support downloading receipt images/PDFs via signed URLs and uploading attachments via signed uploads, with checksum validation and time-limited URLs. Approval states and policy requirements are modeled explicitly in our normalized responses.
