How to get an Anthropic (Claude) API key

Copy page

Create an Anthropic API key and connect it to Workflow Functions to generate functions with Claude.

To use Write with AI with Claude, connect your own Anthropic API key. Here's how to create one - it takes a minute.

Create the key

  1. Go to the Anthropic Console and sign in (or create an account): console.anthropic.com.
  2. Open Settings -> API keys - direct link: console.anthropic.com/settings/keys.
  3. Select Create Key, give it a name (for example Workflow Functions), and copy the key - it starts with sk-ant-. You can only see it once, so copy it now.
  4. Make sure your Anthropic account has credit or a billing method - generation calls are billed to your account.

Connect it

  1. In your Shopify admin, open Workflow Functions -> Developer -> Connections.
  2. Paste the key into the Anthropic (Claude) card and select Save key.

Your key is encrypted at rest and used only for generation - it's never shown again and never runs inside your functions. Then open a function and select Write with AI.
