Using the Lynkd API

The Lynkd REST API lets you create, update, and delete links programmatically. API keys are available on the Agency plan.

Generating an API key

Go to API Keys in the sidebar.
Click Generate New Key.
Give the key a name (e.g. "Zapier integration").
Copy the key immediately — it is shown only once.
