Kroger

Search products, add to cart, and find store locations via the Kroger public API.

Prerequisites

• Kroger developer account at https://developer.kroger.com
• Registered application with Product and Cart API access
• OAuth redirect URI configured in the Kroger app settings

Environment Variables

Set these before using:

export KROGER_CLIENT_ID="your-client-id"
export KROGER_CLIENT_SECRET="your-client-secret"

Optional:

• KROGER_TOKEN_FILE — token storage path (default: ~/.kroger-tokens.json)
• KROGER_REDIRECT_URI — OAuth callback URL (default: http://localhost:8888/callback)
• KROGER_LOCATION_ID — store ID for location-specific product availability

Setup (One-Time)

1. Register a Kroger Developer App

1. Go to https://developer.kroger.com
2. Create an application
3. Enable Product and Cart scopes
4. Set redirect URI to http://localhost:8888/callback
5. Note Client ID and Client Secret

2. Authenticate

Run the auth flow — opens a browser for Kroger login:

scripts/kroger.sh auth

If the redirect URI isn't localhost (e.g., cloud-hosted), use the manual flow:

1. Open the AUTH_URL printed by scripts/kroger.sh auth
2. Log in at Kroger
3. Copy the redirected URL (even if the page errors)
4. Extract the code parameter and run:

scripts/kroger.sh exchange <code>

Tokens auto-refresh. Re-auth only needed if refresh token expires.

Actions

Search products

scripts/kroger.sh search "cannellini beans"

Returns up to 5 results with product IDs, descriptions, and brands.

Add to cart

scripts/kroger.sh add <productId> [quantity]

Requires prior OAuth login. Quantity defaults to 1.

Find nearby stores

scripts/kroger.sh locations <zipcode>

Returns up to 5 stores with location IDs. Set KROGER_LOCATION_ID to filter product search by store.

Check auth status

scripts/kroger.sh token

Workflow: Grocery List → Cart

Typical flow for adding a grocery list to Kroger:

1. Search each item: scripts/kroger.sh search ""
2. Pick the best match from results
3. Add to cart: scripts/kroger.sh add
4. Repeat for all items

When adding many items, batch all searches first, then confirm selections with the user, then add all to cart.
