The developer platform for spend automation
Build integrations with Volopay to automate card requests, user management, project synchronization and organizational workflows — over a clean, OAuth2-secured REST API.
Everything you need to integrate
A focused REST API surface: authenticate once, then read your organization and move money programmatically.
OAuth2 authentication
Client-credentials flow issues short-lived bearer tokens. No passwords on the wire.
User directory
List and filter users across your organization by status, role and location.
Projects & departments
Sync the projects and departments that own budgets and card spend.
Programmatic cards
Create virtual card requests and update limits on behalf of users with full budget controls.
Expenses & bills
Pull transactions, track receipts and settlement, and raise purchase bills against vendors.
Predictable responses
JSON everywhere, paginated lists, and standard HTTP status codes for errors.
From credentials to a live card request
Four steps take you end-to-end. Each card links straight into the API reference.
