Your products live in a Meta catalog. Until now you edited them in Meta Commerce Manager and LazyApp only read them. With **Products** you change them from LazyApp: one at a time in the console, many at once from a spreadsheet, or in bulk over the API. Every change goes to Meta through its Catalog Batch API. Meta applies changes in the background, usually within a minute, so LazyApp queues each change, sends it, and keeps checking until Meta is done. Rows Meta refuses come back with the reason in plain words. > [!NOTE] > > Catalog is on the Growth and Pro plans. On a smaller plan you can still see and remove products, but not add, edit or upload them. Test mode is never limited. See [Plans and limits](https://docs.lazyapp.in/billing/pricing-and-tiers.md#feature-gating). > [!WARNING] > > Changing a catalog needs Meta's `catalog_management` permission for LazyApp. Meta is still reviewing that request. Until it is approved, **Products** shows your products and the full flow, marked **Waiting for Meta approval**, and the API returns `403` with `code: meta_approval_pending`. Reading products works today. ## Before you start Connect a catalog to your number: **WhatsApp numbers → your number → Shop**, then paste the catalog ID from Commerce Manager. See [Shop settings](https://docs.lazyapp.in/sending/catalog.md#shop-settings). ## In the console Open **Products**. * **Add product.** Enter a name, price and photo. Stock is optional: leave it empty if you don't count stock, or enter how many can be sold. At `0` the product shows as out of stock. **More details** holds the product code (SKU), a product page link, brand and condition. * **Edit.** Click a product. Only what you change is sent. * **Remove.** Use the row menu. Orders already placed are not affected. * **Upload spreadsheet.** Download the template, fill it in Excel or Google Sheets, save as CSV and upload it. Progress shows under **Recent changes**, with every row that needs fixing. ### What LazyApp fills in for you Meta requires a product page link, brand, condition and description for every new product. A shop owner rarely has all four, so for a new product LazyApp uses: | Field | Default | | - | - | | Product page | A chat link to your number, `https://wa.me/` | | Brand | Your business name | | Condition | `new` | | Description | The product name | A photo you pick in the console is stored by LazyApp and given to Meta as a private link only Meta knows, because Meta downloads catalog photos more than once. ## Spreadsheet format The first row names the columns. Only `sku` is required in every row. | Column | Notes | | - | - | | `sku` | Your product code. No spaces or commas. Also accepted: `id`, `retailer_id`, `code` | | `title` | Product name. A row with a title is a full product: it is added, or replaces the one with the same code | | `description` | Optional | | `price` | Written normally: `499`, `1,299.50` | | `currency` | 3 letters. Defaults to `INR` | | `availability` | `in stock` or `out of stock` | | `quantity` | Whole number. `0` marks the product out of stock | | `image_url` | Public `https://` photo, at least 500 × 500 pixels | | `link`, `brand`, `condition` | Optional | | `action` | `delete` removes the product | A row with only `sku` and a few columns updates just those columns, so a stock update can be two columns wide: ```csv theme={null} sku,quantity TSHIRT-RED-M,12 MUG-01,0 ``` LazyApp checks every row before sending it. A row with a problem, such as a price that is not a number, is skipped and listed with its row number; the other rows still go through. One file can hold up to 20,000 products and 10 MB. ## Over the API ```bash theme={null} curl -X POST "https://lazyapp.in/v1/catalog/items" \ -H "Authorization: Bearer $LAZYAPP_API_KEY" \ -H "Idempotency-Key: catalog-2026-10-20" \ -H "Content-Type: application/json" \ -d '{ "items": [ { "sku": "TSHIRT-RED-M", "title": "Red cotton T-shirt (M)", "price": 49900, "currency": "INR", "quantity": 25, "image_url": "https://acme.example/images/red-tee.jpg" }, { "action": "update", "sku": "MUG-01", "quantity": 0 }, { "action": "delete", "sku": "OLD-ITEM-7" } ] }' ``` **Scope:** `catalog:write` | Field | Notes | | - | - | | `items` | 1 to 5,000 changes. Split larger catalogs across calls | | `items[].action` | `upsert` (default) adds or replaces the product and needs `title`, `price` and `image_url`. `update` changes only the fields you send. `delete` removes it | | `items[].price` | Minor units: `49900` with `INR` is ₹499.00 | | `items[].availability` | `in_stock` or `out_of_stock` | | `items[].quantity` | How many can be sold. `0` also marks it out of stock | | `connection_uuid`, `phone_number_id` | Pick the number when the workspace has more than one | The response is `202` with the queued change: ```json theme={null} { "id": "9b7c7d0e-4c55-4f0a-9d7e-2f1e3a3b6c11", "catalog_id": "1234567890", "source": "api", "status": "queued", "status_label": "Waiting to send", "filename": null, "total_rows": 3, "skipped_rows": 0, "error_count": 0, "errors": [], "failure_message": null, "created_at": "2026-10-20T10:15:00+00:00", "finished_at": null } ``` ### Check the result ```bash theme={null} curl "https://lazyapp.in/v1/catalog/batches/9b7c7d0e-4c55-4f0a-9d7e-2f1e3a3b6c11" \ -H "Authorization: Bearer $LAZYAPP_API_KEY" ``` **Scope:** `messages:read` `status` moves from `queued` to `processing`, then to `finished`, `finished_with_errors` or `failed`. Each entry in `errors` names the item by its position in `items` (`line`, starting at 1) and its `sku`: ```json theme={null} { "line": 2, "sku": "MUG-01", "message": "The price is not valid. Use a number such as 499 or 499.50." } ``` Poll every few seconds while `status` is `queued` or `processing`. Small changes finish within a minute; a 5,000-row change can take several. ### Errors | Status | When | | - | - | | `403` with `code: meta_approval_pending` | Meta has not approved catalog changes for LazyApp yet | | `403` | The key lacks `catalog:write`, or is restricted from this number | | `422` | A field failed validation, or the number has no catalog connected | Read products with [`GET /v1/catalog/products`](https://docs.lazyapp.in/sending/catalog#list-products).
