Welcome to the Flexprice API

The Flexprice API lets you programmatically manage pricing, subscriptions, and billing for your SaaS application.

​
Base URL

All API requests must use one of the following base URLs:
  • US Region: https://us.api.flexprice.io/v1
  • India Region: https://api.cloud.flexprice.io/v1
Select your preferred region using the server selector in the API playground:

​
Authentication

All API endpoints require authentication using an API key. Include your API key in the x-api-key header with every request. 
x-api-key: <your_api_key>
Create API keys in the Flexprice Dashboard. If you need help, email us at [email protected].
