Do you offer an API?
Yes. Klutch offers a developer API that allows you to programmatically access and manage key account features, virtual cards, transactions, and more. It's ideal for advanced users building automations, custom workflows, or financial integrations.
How do I access the API?
You can start using the Klutch API right away—no special approval is needed. Just download the Postman collection. To authenticate, use your Klutch username and password directly in Postman. The collection includes preconfigured requests and authentication flows, so you can begin testing and integrating without setup delays.
Do you have a Postman collection?
Yes. We provide a fully documented Postman collection to help you explore and test endpoints quickly.
What can I do with the API?
The API allows you to:
Generate and manage virtual cards
Set spending controls and rules
View and filter transactions
Trigger card termination or lock/unlock
Pull account data for reporting or analysis
Export transaction history for accounting or budgeting
Apply advanced transaction rules that makes the approve or decline whenever you want.
We’re constantly adding new capabilities based on developer feedback.
Are there rate limits?
Yes. Our API is rate-limited to ensure system stability. Default limits are suitable for most personal and business use cases. If you need a higher limit, you can request an increase through the developer portal.
Is the API free to use?
Yes. The API is free for approved users, with reasonable rate limits and fair use policies.
Where can I get help with API errors or integration questions?
We offer developer support via our API documentation portal and a dedicated email or Slack channel. You can also use the feedback form in the developer dashboard to report issues or request new features.
