Manage questions & contacts

When users browse classified items (real state, cars and services), they are able to contact the item’s owner through a form displayed on the listing or they can see the owner’s phone (see phone). In the event of a question, when made, it is automatically sent to the message inbox, within the client account in Mercado Libre. It is very important that your integration reads the questions, and also enables users to answer them through your system. In order to learn how to manage questions and answers (leads), check our guide of Questions and answers management. Here you will find all the necessary content to execute the integration of leads of Mercado Libre. Apart from the guide mentioned above, you can check data on questions and record the number of clicks the option “See telephone” got. These methods are detailed below. Remember that the publications with the button "I want to be contacted", when this is pressed by the buyer, a new question will be generated in the same API of questions and answers.
