Validations

Our goal is to improve the quality of our sellers' listings. For this reason we provide a flow that validates consistencies within the listing before its creation and, on certain occasions, requests corrective actions from the seller to meet the expected requirements.
Example of a response with validations after executing the request to create a listing:
