DigiKey is the primary source for prototype orders (Mouser is secondary). Its API returns direct PDF datasheet links, making it the preferred datasheet source. For production orders, see lcsc/jlcpcb. For BOM management and export workflows, see bom.

API Credential Setup

The DigiKey API requires OAuth 2.0 credentials. Here's how to set them up:

1. Create a DigiKey account at digikey.com if you don't have one
2. Register an API app at developer.digikey.com:
   • Sign in with your DigiKey account
   • Go to "My Apps" → "Create App"
   • App name: anything (e.g., "kicad-happy")
   • Select "Product Information v4" API
   • OAuth type: Client Credentials (2-legged, no user login needed)
   • Callback URL: https://localhost (not used for client credentials, but required)
   • After creation, note the Client ID and Client Secret
3. Set the environment variables before running the scripts:

   export DIGIKEY_CLIENT_ID=your_client_id_here
   export DIGIKEY_CLIENT_SECRET=your_client_secret_here
   

   If credentials are stored in a central secrets file (e.g., ~/.config/secrets.env), load them first:

   export $(grep -v '^#' ~/.config/secrets.env | grep -v '^$' | xargs)
   

The client credentials flow has no user interaction — once configured, API calls work automatically.
