Summary recommendations for fashion listings
- Complete the technical sheet for the item.
- Review genders by country using the /catalog_domains/$DOMAIN_ID/attributes/GENDER resource so that your listings reference genders are recognized by the Mercado Libre.
- Upload all the required attributes, as well as variations in your listings.
- Identify if any quality requirements are not complied and take the necessary actions.
- Confirm if the domain has attributes configured for the size chart. When you find an attribute of type GRID_ID and GRID_ROW_ID you will recognize that for this domain the size chart is required, and will not allow you to create or modify it without having the size chart loaded correctly.
Define fashion domain to publish
To advance in the publication flow of a fashion article with an associated size chart, it is necessary to run the category predictor through the /domain_discovery resource to obtain the domain_id data on which it will be published.

]Domains with uploaded size charts
This resource aims to inform the domains that have size charts created (SPECIFIC type) for a specific site. You must send in the body of the POST the filter type=SPECIFIC and the corresponding site.
Request:
curl -X POST -H 'Authorization: Bearer $ACCESS_TOKEN' -H "Content-Type: application/json" -d https://api.mercadolibre.com/catalog/charts/domains/search
{
"site_id": "CBT",
"type": "SPECIFIC"
}Response:
"domains": [
{
"domain_id": "SNEAKERS"
},
{
"domain_id": "BOOTS_AND_BOOTIES"
},
{
"domain_id": "SANDALS_AND_CLOGS"
},
{
"domain_id": "LOAFERS_AND_OXFORDS"
},
{
"domain_id": "FOOTBALL_SHOES"
}
]
}Consult domain data sheet
Once the category and domain have been identified for the publication, you must consult the /domains/$domain_id/technical_specs resource and consult the domain's data sheet, recognizing the attributes with value_type: grid_id and grid_row_id that will allow you to identify if the domain requires a size chart.
Additionally, you will have to recognize those attributes with the grid_template_required tag which will be required for the size chart data sheet search.
Request:
curl -X GET -H 'Authorization: Bearer $ACCESS_TOKEN' https://api.mercadolibre.com/domains/$DOMAIN_ID/technical_specsExample consulting the CBT-SNEAKERS domain data sheet:
curl -X GET -H 'Authorization: Bearer $ACCESS_TOKEN' https://api.mercadolibre.com/domains/CBT-SNEAKERS/technical_specsResponse with the details of the domain's datasheet:

}Consulting a size charts data sheet
The size chart data sheet will determine the structure of the attributes with a measure table in the listing, you should execute a POST to the resource of /domains/$domain_id/technical_specs?section=grids and send all the attributes previously recognized with the grid_template_required tag.
Request:
curl -X POST -H 'Authorization: Bearer $ACCESS_TOKEN' -H "Content-Type: application/json" -d {...} https://api.mercadolibre.com/domains/$DOMAIN_ID/technical_specs/?section=gridsExample consulting the details of the technical data sheet for a specific size chart (personalized) and the female gender:
curl -X POST -H 'Authorization: Bearer $ACCESS_TOKEN' -H "Content-Type: application/json" https://api.mercadolibre.com/domains/CBT-SNEAKERS/technical_specs/?section=grids

}Validations and error messages
The requirement of the size chart is meant to validate if the information in the listing is consistent by using error messages, which we detail below.
In the validations of the requirement of a size chart for Live Listing, are not considered adjustments such as:
- Stock and price changes in the listing
- Paused or closed status changes in the listing
This means that, the error will not appear at the moment you make a PUT to the /items/ resource.
1. The SIZE_GRID_ID attribute does not exist in the listing:
{
"code": "missing.fashion_grid.grid_id.values",
"message": "Attribute [SIZE_GRID_ID] is missing",
"type": "ERROR",
"cause_id": 2610,
"references": [
"item.attributes"
],
"department": "structured-data",
"validation": "fashion-validator",
"custom_data": {}
}2. For the listing where there is the SIZE_GRID_ID attribute, but there is no attribute that specifies the row SIZE_GRID_ROW_ID:
{
"code": "missing.fashion_grid.grid_row_id.values",
"message": "Attribute [SIZE_GRID_ROW_ID] is missing",
"type": "ERROR",
"cause_id": 2611,
"references": [
"item.attributes"
],
"department": "structured-data",
"validation": "fashion-validator",
"custom_data": {}
}3. For the listing and/or its variations the attribute SIZE is not specified:
{
"code": "missing.fashion_grid.size.values",
"message": "Attribute [SIZE] is missing",
"type": "ERROR",
"cause_id": 2612,
"references": [
"item.attributes"
],
"department": "structured-data",
"validation": "fashion-validator",
"custom_data": {}
}4. The listing with the SIZE_GRID_ID attribute specification, but the table code sent is invalid, for example when the listing associates a size chart of another category:
{
"code": "invalid.fashion_grid.grid_id.values",
"message": "Attribute [SIZE_GRID_ID] is not valid",
"type": "ERROR",
"cause_id": 2613,
"references": [
"item.name"
],
"department": "structured-data",
"validation": "fashion-validator",
"custom_data": {}
}5. The listing has the attribute specification SIZE_GRID_ID and SIZE_GRID_ROW_ID but the id sent in row is invalid, it does not exist in the table specified in grid_id:
{
"code": "invalid.fashion_grid.grid_row_id.values",
"message": "Attribute [SIZE_GRID_ROW_ID] is not valid",
"type": "ERROR",
"cause_id": 2614,
"references": [
"item.name"
],
"department": "structured-data",
"validation": "fashion-validator",
"custom_data": {}
}6. The size attribute of the listing or variation must consistently match the row in the table you are selecting; they must be identical if the SIZE of the listing or variation is invalid in this comparison:
{
"code": "invalid.fashion_grid.size.values",
"message": "Attribute [SIZE] is not valid",
"type": "WARNING",
"cause_id": 2615,
"references": [
"item.name"
],
"department": "structured-data",
"validation": "fashion-validator",
"custom_data": {}
}7. The attributes detailed in the table must correspond consistently with the information in the listing, for example, the GENDER attribute in the table must be the same as the one in the listing:
{
"code": "invalid.fashion_grid.size.values",
"message": "Attribute [GENDER] is not valid",
"type": "WARNING",
"cause_id": 2616,
"references": [
"item.name"
],
"department": "structured-data",
"validation": "fashion-validator",
"custom_data": {}
