🌐 Generate Dynamic Links via REST API

Use ChottuLink's REST API to programmatically create dynamic links from your backend or server-side scripts. This is ideal for scenarios where links need to be generated outside the app, such as in marketing campaigns, transactional messages, or automated workflows. Simply make a POST request with the required parameters, and receive a fully-qualified short or long link in response.

Authentication

Include your API key in the request header:
