Buscador de productos

Previo a publicar un producto en catálogo dentro de una página de producto o PDP es importante confirmar si el producto de catálogo es el adecuado con base a la ficha técnica de tu publicación de marketplace, y características adicionales como el status del producto, el precio, entre otros. . El buscador de productos de catálogo te permite identificar los productos para publicar de manera directa en catálogo y/o mediante publicaciones asociadas del marketplace.

Nota:
Los vendedores pueden consultar el catálogo de productos de Mercado Libre desde el front y, por medio del product id, podrán publicarlos mediante la integración o el mismo front.

Parámetros

site_id: String que representa el país. Obligatorio.
status: Si no envías este parámetro, por defecto traerá todos los resultados, tanto activos como inactivos.

  • status=active: Devuelve los productos de catálogo en estado activo y por ende pueden elegirse para asociar a una publicación de marketplace.
  • status=inactive: Devuelve los productos que todavía no son elegibles para asociar a una publicación de marketplace, porque se encuentran inactivos.

q: String con palabras claves de búsqueda, es importante tener en cuenta que en este campo se puede enviar tantos detalles de los atributos de tu publicación como sean necesarios, de esta manera en el response obtendrás búsquedas más acertadas y evitarás posibles moderaciones por mala productización de las publicaciones de marketplace. Ejemplo: “Celular Samsung Galaxy S8 Negro 64 GB dual sim”. Este parámetro es obligatorio de no enviar el product_identifier en el request.
product_identifier: String con el código universal del producto. Ejemplo: GTIN el cual engloba los diferentes PIs (EAN, UPC, ISBN, etc). Obligatorio en caso de no enviar una cadena de palabras claves en el parámetro q.
domain_id: String con el dominio en el cual se quiere publicar (Opcional).
offset: Posición desde la que se devuelven los resultados de la búsqueda (Opcional).
limit: Cantidad de resultados que devuelve la búsqueda (Opcional).


Llamada con parámetro “q”:

curl -X GET -H 'Authorization: Bearer $ACCESS_TOKEN' https://api.mercadolibre.com/products/search?status=$STATUS_ID&site_id=$SITE_ID&q={q}

Ejemplo con parámetro “q”:

curl -X GET -H 'Authorization: Bearer $ACCESS_TOKEN' https://api.mercadolibre.com/products/search?status=active&site_id=MLA&q=Samsung 20 Galaxy S8 64 GB rosa'

Para que un ítem pueda ser publicado en catálogo y ser comprado, tiene que estar asociado a un producto de catálogo o también denominado página de producto (PDP). Los productos de catálogo son creados por Mercado Libre, donde nos aseguramos que son suficientemente específicos (Ficha técnica completa) tal que el comprador pueda saber con precisión qué está comprando (productos con status=”active” en el recurso /products/{product_id}).


Detalle de productos

Una vez identificado el producto de catálogo, puedes conocer sus características principales con el recurso /products/$PRODUCT_ID. De esta manera, será posible crear un ítem de mejor calidad.

Los productos de catálogo o páginas de productos PDP, en general, se componen de varios productos asociados que compiten entre sí. El campo de "buy_box_winner" indica cuál de los productos está actualmente ganando por ofrecer mejores condiciones de venta. Cuando no hay ningún producto de catálogo compitiendo, este campo viene en null.

Importante:
El contenido de la publicación de catálogo es provisto por Mercado Libre. Por lo tanto, el vendedor es responsable de confirmar que el producto a asociar coincida con las características específicas que se muestran en la plataforma.
En caso que exista una diferencia entre lo que el usuario compre y el producto asociado es posible, que se generen reclamos y/o cancelaciones que impactarán negativamente en su reputación y como consecuencia de esto la inhabilitación para publicar en catálogo, llevando eventualmente a la suspensión de la cuenta.

Productos padres y hijos

Productos de nivel superior (“padres” o “parents”) agrupan varios productos de catálogo específicos y no son aptos para ser comprados. Ejemplo: Motorola Moto G6. Este no tiene la capacidad ni el color especificado.
Productos de nivel terminal (“hijos” o “children”) productos de catálogo suficientemente especificados, es decir, con su ficha técnica completa, y por ende están habilitados para ser comprados. Ejemplo: Motorola G6 32 GB Índigo oscuro.

Ejemplo de un producto padre (no es específico y que no se puede comprar):

Al momento de publicar en productos de catálogo, se debe tener en cuenta que:

El campo "children_ids" de la respuesta anterior:

  • Si el campo está vacío, se trata de un producto hijo, el cual está suficientemente específico para publicar.
  • Si este campo contiene IDs de otros productos, quiere decir que el catalog_product_id actual corresponde a un producto padre (no completamente especificado). Para publicar en catálogo debemos buscar un producto específico entre sus children_ids.

El campo “status” de la respuesta anterior:

  • Para poder crear una publicación de catálogo es necesario que el producto tenga status=”active”.
  • Los productos padres nunca tendrán status=”active” porque no pueden comprarse.

Elegir el producto para publicar

Tu publicación de marketplace y/o sus variaciones elegibles para catálogo poseerán un campo “catalog_product_id” que deberás verificar previo a la publicación en catálogo, ya que este campo te informa cuál es producto de catálogo adecuado para publicar en el recurso /products/$CATALOG_PRODUCT_ID.

Ejemplo para obtener la información del“catalog_product_id” en una publicación de marketplace:

curl -X GET -H 'Authorization: Bearer $ACCESS_TOKEN' https://api.mercadolibre.com/items/MLA1150086340

Al momento de crear una publicación de catálogo a partir de una publicación de marketplace elegible, tienes que verificar con nuestro recurso de productos /products/$CATALOG_PRODUCT_ID:

  • Si el campo <“catalog_product_id” corresponde a un producto con status active, si es así estás listo para publicar en catálogo utilizando ese “catalog_product_id”.
  • Si el campo “catalog_product_id” corresponde a un producto con status inactive, deberás informar a Mercado Libre para que se vuelva a productizar tu publicación de marketplace, ya que si intentas publicarla en catálogo obtendrás error.
  • Si el array “children_ids” está vacío, quiere decir que la publicación o variación ya está asociada al producto más específico que tenemos y este no está aún listo para publicarse en catálogo, por lo que no podrás crear la publicación de catálogo hasta que el producto esté editado por Mercado Libre.
  • Si el array “children_ids” no está vacío, deberás buscar entre los productos children el que corresponde exactamente (comparando las fichas técnicas) con lo que estás vendiendo.
