Rewe Order

Batch-add items to REWE Lieferservice cart via their internal API. All items added in ONE JavaScript call — no clicking buttons.

Prerequisites

• User logged into rewe.de in Chrome (connect via tabs_context_mcp)
• Delivery time slot selected (if "Liefertermin wählen" visible, user must select first)

Process

Step 1: Get market UUID (once per session)

Navigate to any REWE product page, wait 2s, then:

const marketUuid = document.body.innerHTML.match(/\d+-[\w]+-([0-9a-f-]{36})/)?.[1];

Step 2: Batch add all items (single JS call)

(async () => {
  const uuid = '<MARKET_UUID>';
  const items = [
    {search: 'Product Name 250g', qty: 1},
    // ... all items — use German names with package size
  ];
  const results = [];
  for (const item of items) {
    try {
      // Search WITH cookies (critical — without credentials, no product data)
      const html = await (await fetch(
        `/shop/productList?search=${encodeURIComponent(item.search)}`,
        {credentials: 'include'}
      )).text();
      // Extract product JSON block
      const blocks = html.match(/\{"articleId":"[^"]+","availability[^}]+\}/g) || [];
      const products = blocks.map(b => JSON.parse(b));
      if (!products.length) { results.push({item: item.search, error: 'NOT_FOUND'}); continue; }
      // Find full listingId
      const artId = products[0].articleId;
      const lid = html.match(new RegExp(`\\d+-${artId}-${uuid}`))?.[0];
      if (!lid) { results.push({item: item.search, error: 'NO_LISTING'}); continue; }
      // Add to cart
      const r = await fetch(`/shop/api/baskets/listings/${lid}`, {
        method: 'POST', credentials: 'include',
        headers: {'content-type':'application/json','x-origin':'AddToBasketV2',
          'x-application-id':'rewe-basket','Accept':'application/vnd.com.rewe.digital.basket-v2+json'},
        body: JSON.stringify({quantity: item.qty, includeTimeslot: false, context: 'product-detail'})
      });
      results.push({item: item.search, price: products[0].price, status: r.status, ok: r.ok});
    } catch(e) { results.push({item: item.search, error: e.message}); }
  }
  return results;
})()
