API & Integration -> API Reference
Where can I find my API key?
Each project in your account has its own unique API key. This allows you to keep projects separate, which is useful for distinguishing between development and production environments or organizing templates from different customers under separate projects.
You can find your API key under Project Settings in your Creatomate dashboard:
Your API key can also be found in the quick start examples available for cURL, Node.js, PHP, and others. You need to be logged in to see it.
