API keys let external applications authenticate with your account. Treat them like passwords and never expose them in client-side code.
Create a key
- Go to Settings → API.
- Click Generate new key and give it a descriptive label.
- Copy the key immediately — it is shown only once.
Using the key
Send the key in the request header on every call:
X-API-KEY: pk_your_key_hereIf a key is ever leaked, revoke it from the same screen and generate a replacement.
