API Endpoints

Lithic provides two environments for development and production use:

Production	`https://api.lithic.com/v1`	Use this environment for live card programs with real transactions and financial activity.

All API requests must include your API key in the Authorization header using HTTP Basic Authentication:

  -u {your_api_key}:

Or include the full Authorization header:
