Spendesk API
Spendesk is spend management software for finance teams to control company spending across cards, invoices, and employee reimbursements. An unofficial API lets you programmatically pull card transactions, cards and controls, expense claims with receipts, vendors and invoices, reimburs
What is Spendesk?
Spendesk is a cloud platform that centralizes company spending across corporate cards, invoices, subscriptions, and reimbursements. Finance, managers, and employees use Spendesk to request and approve spend, capture receipts, process supplier invoices, assign costs to teams or cost centers, manage budgets, and reconcile with accounting systems.
Core product areas include:
- Corporate Cards (virtual and physical), merchant controls, spend limits
- Expense Management (claims, receipts, mileage, per diem)
- Accounts Payable (invoice capture, approvals, coding, payments)
- Budgets & Cost Centers (policy enforcement, tracking)
- Subscriptions (recurring vendor payments, renewals)
- Approvals & Workflows (multi-step, role-based)
- Accounting Integrations (export to GL, tax/VAT handling)
Common data entities:
- Companies, Users, Roles/Permissions (Finance, Manager, Employee)
- Cards (physical/virtual), Card Assignments, Controls
- Card Transactions (merchant, MCC, amounts, VAT)
- Expense Claims (line items, receipts, categories, status)
- Vendors/Suppliers (contact info, terms)
- Invoices/Bills (header, lines, tax, approvals, payments)
- Reimbursements (payouts, methods, status)
- Budgets & Cost Centers (allocations, remaining, policy)
- Approvals (steps, approvers, timestamps)
The Spendesk Integration Challenge
Finance teams rely on Spendesk daily, but turning portal-based workflows into API-driven automation can be hard:
- Role-aware portals: Employees, managers, and finance each see different data, permissions, and approval states
- Inconsistent export paths: Many teams report relying on CSV exports or manual downloads, with limited webhook coverage or paid API tiers
- Card controls & policies: Merchant categories (MCC), limits, and freeze states require careful, audited changes
- Multi-currency & VAT: Accurate tax coding and exchange-rate handling complicate data normalization
- Attachments & receipts: Files, OCR results, and audit trails live across views and need stable access
- Authentication complexity: SSO/MFA and session lifecycles complicate headless automation

Expenses
/expensesList employee expense claims with filters and summary details.
Invoices
/invoicesCreate a supplier invoice with line items, tax/VAT, and approval metadata.
Cards
/cards/{cardId}Update card limits, freeze state, and assignment.
Transactions
/transactionsList card transactions with merchant and VAT details.

Frequently asked questions
Supergood supports workflows across commonly used modules such as Corporate Cards (card provisioning, controls, transactions), Expense Management (claims, receipts), Accounts Payable (invoices, approvals, payments), and Budgets/Cost Centers, 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 invoices, reimbursements, and card transactions to match your ERP/accounting schema (e.g., GL accounts, tax codes) and deliver updates via webhooks or polling while complying with rate and permission constraints. We commonly integrate with QuickBooks and Xero.
Yes. We support downloading receipt images/PDFs and uploading attachments via signed uploads, with checksum validation and time-limited URLs. OCR metadata is modeled explicitly in our normalized responses when available.
