Connect a store (cross-org, no app review)

For 2026 Shopify Dev Dashboard. The store creates a custom app in its own admin, you paste the app's Client ID + Secret here. We mint a 24h token automatically.
Steps the store owner does (≈3 min)
  1. Shopify admin → Settings → Apps and sales channels → Develop apps → Build apps in Dev Dashboard
  2. Create app → name it "Intercart"
  3. Open the app → set Admin API access scopes to:
    read_orders, write_orders, read_products, read_customers, write_customers, read_shipping, write_script_tags, read_script_tags
  4. Release / install the app on the store (create a version & release, then install it on the store)
  5. App → Settings → Credentials → copy the Client ID and click Reveal to copy the Secret
Then paste them here
After connecting, open that store's dashboard to add its own PayPal / Stripe / Facebook keys. Payment buttons appear automatically — no theme editing.
