How do I create an API key?

Create, store and revoke keys from the dashboard.

Updated November 3, 2026

Table of contents
  1. Click your name at the bottom of the sidebar and open API Keys.
  2. Click Create API key.
  3. Give the key a name and choose when it expires, or never.
  4. Copy the key. It starts with ll_live_ and is shown only once, so store it somewhere safe, like a secrets manager.

Good to know

  • Each key belongs to one project. A project can have up to 10 keys.
  • Project owners and admins get an email whenever a key is created, renamed or revoked.
  • You can rename a key at any time.

Revoke a key

On the API Keys page, revoke any key you no longer use or think may be exposed. It stops working immediately.
