Getting started

Superface is all about you, the consumer of API capabilities. To get started, first pick a capability and its provider, install it to your App and use Superface OneSDK to make the call.


This guide is more detailed version of the in-product Getting started available at

Superface in 3 minutes

The following steps will guide you how to quickly get started with Superface and OneSDK.


This guide assumes you have Node.js version 14 or newer installed.

Pick a capability

Decide what capability you would like to use in your App. A capability is described by its profile with unique ID.

In this guide we will use the capability List user repositories of a VCS like GitHub or GitLab. Its ID is vcs/user-repos.

Capability details

To see a detailed description of the capability, check the vcs/user-repos profile page.

Pick a provider

The next step is to pick a provider you would like to use. In this guide we will use the github.

Additional providers

Find the list of supported capability providers at vcs/user-repos profile page.

Install OneSDK

In your App directory, install the OneSDK library:

npm install @superfaceai/one-sdk

Install the capability

Next, add the vcs/user-repos capability to your App using the Superface CLI:

npx @superfaceai/cli install vcs/user-repos

Configure the provider

The next step is to configure the provider. In our case we configure github for capability profile vcs/user-repos:

npx @superfaceai/cli configure github --profile vcs/user-repos
Provider authentication

In many cases you also need to set up provider credentials. Since we are using the unauthenticated GitHub API we can skip it for now.

To learn how to handle API credentials, see Setting provider API keys.


Finally, use OneSDK in your App. Create the index.js file with the following JavaScript code:

const { SuperfaceClient } = require('@superfaceai/one-sdk');
const sdk = new SuperfaceClient();

async function main() {
// Load the capability profile
const profile = await sdk.getProfile('vcs/user-repos');

// Invoke the capability use case
const result = await profile
user: 'superfaceai',

// Handle the result
try {
const data = result.unwrap();
} catch (error) {



With the capability installed, provider configured, and OneSDK, it is the time to execute your App:

Check the HTTP communication

Set the environment variable DEBUG to superface:http* to see API calls from OneSDK to GitHub API:

DEBUG="superface:http*" node index.js

This can print out potentially sensitive information.

Set the DEBUG environment variable to superface* to see everything what is going in under the hood.

Understand runtime integration

During the App runtime OneSDK downloaded a Comlink map from Superface servers. The Comlink map instructs the OneSDK how to make the direct call to GitHub API to perform the capability.

You can always check the Comlink map at profile's detail page for the given provider by clicking the "raw" link. For example here's the latest map for vcs/user-repos and github.

Next step

With your first capability set up, you can now start monitoring the integrations in Superface insights.
