Answer questions

When you have a large amount of items listed on Mercado Libre you’re probably gonna receive lots of questions so we recommend you develop a way to answer those questions in a semi-automatic way, where answers are suggested to operators basing on frequent keywords. To do so, you need to know how to answer a question by API. This is gonna be easy. First, let’s check all the questions you got on your item. Just make a question search by item like in the example:

curl -H 'Authorization: Bearer $ACCESS_TOKEN' -X GET https://api.mercadolibre.com/marketplace/questions/search?item_id=$ITEM_ID

You’ll see questions have a status, so you’ll probably gonna have to keep those under “unanswered” status. Now let’s answer a single question:

curl -H 'Authorization: Bearer $ACCESS_TOKEN' -X POST -H "Content-Type: application/json" -d '{
  "question_id": 3957150025,
  "text":"Test answer...",
  "text_translated": "Translated answer..."
}' https://api.mercadolibre.com/marketplace/answers

Response:

{
   "id": 6894368802,
   "seller_id": 523130418,
   "text": "Hello, I like the product, do home deliveries?",
   "status": "ANSWERED",
   "item_id": "CBT911112427",
   "date_created": "2020-03-20T09:15:01.000-04:00",
   "hold": false,
   "deleted_from_listing": false,
   "answer": {
       "text": "This is the answer from the seller",
       "status": "ACTIVE",
       "date_created": "2020-11-24T15:27:07.321-04:00",
       "text_translated": "Esta es la respuesta del vendedor"
   }
}

When working with questions is very useful to listen to Notifications since it enables you to have a real-time feed of events that occur regarding to them.

Note:
To answer questions, the maximum number of characters is 2000.

 

Delete questions

If you have the need to delete a question an user made on your item just use the DELETE method with the question ID and the seller’s access token.

Request:

curl -H 'Authorization: Bearer $ACCESS_TOKEN' -X DELETE http://api.mercadolibre.com/marketplace/questions/$QUESTION_ID

Example:

curl -H 'Authorization: Bearer $ACCESS_TOKEN' -X DELETE http://api.mercadolibre.com/marketplace/questions/6988272427

Response:

[
    "Question deleted."
]

How does your application know about any news on a question?

A question on an item is an event that occurs on Global Selling side, so you'll need to subscribe to our questions feed to be aware in real time when that event occurs. First of all, we have to configure our application to be capable of getting notifications. This can be done by subscribing your application to questions notifications. Go to our Application Manager and edit your application Notifications Settings. For more information about creating and configuring a new app, please check this guide. You must choose a Callback URL: configure the public URL of your domain where you want to receive all the notifications from MercadoLibre. E.g.: "https://backend.soleorigami.com/notification". Also you need to specify which “topic” you will list, in this case you must select questions. This configuration allows you to interact with MercadoLibre notifications. All the events regarding new questions will be notified to your callback URL.

 

Receiving a notification

Mercado Libre will send you notifications through a POST message with information inside items body. The most important attribute in the message is the user_id which is related to the notification and second one is the resource. The resource is the element that has been updated or it has been created.

{
  "user_id": 1234,
  "resource": "/marketplace/questions/139876",
  "topic": "marketplace_questions",
  "received": "2011-10-19T16:38:34.425Z",
  "sent" : "2011-10-19T16:40:34.425Z",
}

After receiving the notification you must send an acknowledgment (ACK 200) to MercadoLibre in order to stop receiving the notification. Check our Notifications documentation to know further.

 

Error codes reference

Error Description Possible solution
invalid_question: The question is invalid. Can not answer question. The parameter question_id must be a integer number. (To search your question call the resource /marketplace/questions/search).
invalid_post_body: Invalid JSON. Valid attributes are: {0}. Invalid parameters. Expected parameters are question_id and text.
