Integrate Seamlessly with Dependable APIs

Have a reliable means for customers to pay later for your stores online or in-store.

To begin using Klump as your preferred Buy Now, Pay Later solution, you must first create an account.

We are committed to providing you with a seamless integration experience, so we encourage testing during the development.

For all of our transactions, Klump employs standard HTTP response codes. The error codes range from the 200s to the 500s.

Every API request to Klump's endpoints must include an API key, specifically the Klump secret key.

Klump makes use of a single base API endpoint for both sandbox/development and production environment.

After a successful transaction, you must verify that the transaction was successful before providing value to a customer.
