To list products from another WhatsApp Business account:

Add product
POST /whatsapp/catalog/product
{
"from_number": "+595981461442",
"product": {
"name": "Cool T-Shirt",
"image_url": "https://example.com/tshirt.jpg",
"description": "A very cool t-shirt",
"price": "29.99",
"currency": "USD",
"is_hidden": false,
"url": "https://mystore.com/tshirt",
"retailer_id": "SKU-001"
}
}
name and image_url are required. Currency defaults to the number's country currency. At least one product must already exist in the catalog. WhatsApp verification takes minutes to hours.
Edit product
PUT /whatsapp/catalog/product/{product_id}
{
"from_number": "+595981461442",
"product": {
"name": "Updated T-Shirt",
"image_url": "https://example.com/new-tshirt.jpg",
"description": "Updated description",
"price": "34.99",
"is_hidden": false,
"url": "https://mystore.com/tshirt",
"retailer_id": "SKU-001"
}
}
name and image_url cannot be set to null. Edits undergo WhatsApp verification.
Delete product
DELETE /whatsapp/catalog/product/{product_id}
{ "from_number": "+595981461442" }
Add product images
POST /whatsapp/catalog/product/image/{product_id}
{
"from_number": "+595981461442",
"product": {
"image_urls": [
"https://example.com/image1.png",
"https://example.com/image2.png"
]
}
}
Max 2 image URLs per request. Does not replace the default product image.
Delete product image
DELETE /whatsapp/catalog/product/image/{product_id}/{image_index}
{ "from_number": "+595981461442" }
image_index is zero-based. The default product image cannot be deleted.
Collections
List collections
GET /whatsapp/catalog/collections?from_number={your_number}
To list collections from another account:
GET /whatsapp/catalog/collections/{target_number}?from_number={your_number}
Returns collections with id, name, approval_status, and nested products.
Add collection
POST /whatsapp/catalog/collection
{
"from_number": "+595981461442",
"collection": {
"name": "Shoes",
"product_ids": ["9846351425439378"]
}
}
Collection names cannot be changed after creation — delete and recreate instead. Product IDs come from the list products endpoint.
Edit collection
PUT /whatsapp/catalog/collection/{collection_id}
{
"from_number": "+595981461442",
"collection": {
"remove_product_ids": ["product_id_1"],
"add_product_ids": ["product_id_3"]
}
}
The collection ID changes every time you edit it — update subsequent requests with the new ID.
Delete collection
DELETE /whatsapp/catalog/collection/{collection_id}
{ "from_number": "+595981461442" }
