Connect payments to your clients' sites and systems
Use the Kling API and payment window to connect payments to your project. A test environment and documentation let you try the payment flow and size up the work before the solution goes live for a client.
Common challenges today
These are examples of what many people deal with before they start using Kling.
Integrating the payment solution turns out to be bigger than planned
Vague documentation and unexpected requirements can stretch the work and make it hard to estimate time and cost for the client.
You need to try the solution before you choose it
Without access to a test environment it is hard to judge whether the payment solution fits the project and what it takes to connect it to the site or the system.
You need technical help when something goes wrong
When an error comes up in the payment flow you need to reach people who know the solution and can help you find the cause.
How Kling works in development projects
Try the payment flow and connect payments to your project
As soon as you sign up you get test keys and can try the payment flow in the Kling test environment. That way you can judge whether the solution fits the project before you take real payments.
The documentation for the API and the payment window is in English. You can use it while you build, whether you write the code yourself or lean on coding tools.
If the client needs to take payments without a system integration, you can use payment links. They can be sent or published on a website without any code.
If the project needs a custom implementation, get in touch. We go through the needs of the project with you, look at the options and size up the work and the timeline.

It was really simple to set up. I read the docs, connected the API to our booking flow, and we started accepting payments within a few days. This is the payment solution Iceland has been missing, designed exactly the way developers want to work.

We use Kling with Journey for subscriptions, pick-and-pack and deliveries. The integration was smooth and we were up and running fast. It handles our entire subscription flow from checkout to recurring billing — exactly what we needed.

Ask the Kling launcher
The Kling launcher is the chat assistant on the Kling front page. Describe your project and how the payment flow should work. The launcher helps you find the solutions and the documentation that fit the project. You can try it without creating an account.
Get started →I am building a booking site and need to connect payments to the booking flow.
Then the API and the payment window could suit you. Should the customer pay the whole amount at booking, or pay a deposit at booking and the balance later?
