One data model

Kloudless formats all objects with a unified data model ensuring that request and response data structures are identical across all the cloud app connectors in one category.

One set of API endpoints

We abstract away the differences between many cloud app APIs by providing unified API endpoints, so a single API request format will work with all connectors within a category.

One authentication flow

We provide a single access token via a Unified OAuth flow to make authorized API requests on behalf of a user, unifying different auth mechanisms like OAuth, JWT, or password Authentication.


Schedule events on any calendar provider

Your users can schedule their important events or meetings from within your application on their existing cloud calendar service. Provide your users with a seamless experience, no matter which calendaring service they are already invested in.

Frequently Asked Questions

What are some examples?

Kloudless specializes in helping solve several industry use cases across business applications, such as sales enablement, construction, and CASB. Learn more about other industry use cases and how we can help your application here.

What is the difference between you and Zapier / Workflow Automation?

Kloudless is entirely embedded within your application to increase stickiness. Your users will no longer be forced to leave your application to integrate with the services they need. Workflow automation is not an API. It is simply a tool for your customers to perform basic sync while Kloudless is used by your developers to enable synchronous interactivity for users to pull and push data on demand while using your application. Of course, Kloudless also enables automating data transfer as well. Read all about the differences between a Unified API and workflow automation here.

Do you ever leave data out of the unified response?

Services sometimes return objects with properties that are unique or custom to that specific provider, user account, or tenant. This is especially true of highly customizable environments such as CRM apps like Salesforce. However, Kloudless always provides the raw data returned from upstream HTTP responses, and even allows arbitrary requests to any upstream endpoint through the Kloudless Pass-Through API, while still handling authentication and keeping tokens refreshed.

How do I get started?

Sign up today for a free account and see how easy it is to provide your application with all of its API needs. Use our Postman Collection to easily test out each endpoint, or use our language-specific SDKs to quickly get started on integrating with Kloudless.

What is the benefit of Kloudless being embedded in my application?

Every product has its own UI/UX. Since Kloudless is embeddable, users can access any and all of their needed services inside of your application without ever knowing that Kloudless is there at all, increasing your application’s value, experience, and stickiness.

What are the most popular endpoints?

At a broad level, CRUD endpoints and change tracking are central to applications’ use of Kloudless. Keeping track of real-time events that occur in your end user’s cloud service is pivotal to providing your users with the information they need from your application. Kloudless provides this data through our exceptional Activity Monitoring (Events) API, Webhooks, AWS EventBridge partner source, and first-class support for Subscriptions. Kloudless also builds on top of these basic endpoints to support some of our popular advanced functionality and UI Tools, powering scheduling, file browsing, and data mapping use cases across a range of connectors.

How can we deploy Kloudless?

Your application can connect to Kloudless either through our hosted service at, or by self-hosting Kloudless Docker containers in your cloud or on-premises environments. We offer a range of different options for the size and scale of your application through either method. Learn more about your deployment options here.
