Send Requests

Estimated time: ~2 minutes

Authenticate your API requests

To authenticate your requests to our API, include your API key in the “Authorization” header.

"Authorization: {API key}" // Sandbox or Production API key

Select an environment

Lithic exposes two environments for API requests: Sandbox and Production

Sandbox:      sandbox.lithic.com  // Use your Sandbox API key
Production:   api.lithic.com      // Use your Production API key

Sandbox supports all of Production's API endpoints and adds a few more to simulate real world card usage.

Make API requests

Using a Lithic library

Lithic provides client libraries to speed up your time to launching a live card program:

Language	Links	Install Command
Typescript	Github NPM	`npm install lithic`
Python	Github PyPi	`pip install lithic`

We highly recommend using a library for your integration. Our libraries are kept up-to-date, provide types, and simplify some of the more complex parts of the API.

// npm install lithic

const lithic = new Lithic({
  apiKey: "{Sandbox API key}", // or "Production API key"
  environment: "sandbox", // or "production". Defaults to "production"
});

# pip install lithic

lithic = Lithic(
  api_key="{Sandbox API key}",  # or "Production API key"
  environment="sandbox",  # or "production". Defaults to "production"
)

Using cURL

curl --request GET \
     --url https://sandbox.lithic.com/v1/cards \
     --header "Accept: application/json" \
     --header "Authorization: {Sandbox API key}"
