First steps
Before creating listings with size charts, you must have all the details from the product specification sheets that will enable you to learn about the structure for creating size charts and for the subsequent assignment of a chart to a listing.
Therefore, we have detailed the technical flow in the following image to have fashion listings with quality and a size chart correctly linked:
- First steps to have product specification sheet details.
- Manage size chart from the product specification sheet details.
- Validations with possible error messages, moderations and some recommendations.
- Photo quality where we certify fashion listing images.
- No type all custom, standard and by brand chart results are returned. According to the filters uploaded to the POST.
- With type= SPECIFIC all the results of customized charts are returned, according to the filters uploaded to the POST, according to the genre uploaded.
- With type= STANDARD all the results of standard charts are returned according to the filters uploaded to the POST.
- With type= BRAND all chart results by brand are returned according to the filters uploaded to the POST.
Define fashion domain to list
To move forward in the fashion listing flow with a linked size chart, it is necessary to run the category predictor through the /domain_discovery feature and thus obtain the domain_id data on which it will be listed.
Example of category predictor response for a fashion domain:
[
{
"domain_id": "MLA-SNEAKERS",
"domain_name": "Zapatillas",
"category_id": "MLA109027",
"category_name": "Zapatillas",
"attributes": []
}
]Available domains for size chart
You will be able to check the domains linked to the size chart experience by specifying the SITE_ID.
Request:
curl -X GET -H 'Authorization: Bearer $ACCESS_TOKEN' 'https://api.mercadolibre.com/catalog/charts/$SITE_ID/configurations/active_domains'Example of the response obtained for MLA, here the array domains specify all the active domain IDs for the specific country, in the example, Argentina:
{
"domains": [
{
"domain_id": "MLA-SNEAKERS"
},
{
"domain_id": "MLA-BOOTS_AND_BOOTIES"
},
{
"domain_id": "MLA-LOAFERS_AND_OXFORDS"
},
{
"domain_id": "MLA-FOOTBALL_SHOES"
},
{
"domain_id": "MLA-SANDALS_AND_CLOGS"
}
]
}Example of response when the SITE_ID has no active domain for size chart use:
{
"error": "config_not_found",
"message": "Config not found",
"status": 404
}Check product specification sheet of domain
Once you have the category and domain identified for the listing, it is necessary to check the
/domains/$domain_id/technical_specs feature and check the product specification sheet of the domain recognizing the attributes with value_type: grid_id and grid_row_id that will enable to link the size chart information when creating or editing a listing.
Additionally, it is necessary to recognize those attributes with the grid_template_required tag, which will be required for searching the product specification sheet of the size chart.
Request:
curl -X GET -H 'Authorization: Bearer $ACCESS_TOKEN' https://api.mercadolibre.com/domains/$DOMAIN_ID/technical_specsExample that checks the product specification sheet of MLA-SNEAKERS domain:
curl -X GET -H 'Authorization: Bearer $ACCESS_TOKEN' https://api.mercadolibre.com/domains/MLA-SNEAKERS/technical_specsResponse with the details of the product specification sheet of the domain:

}Check the product specification sheet of the size chart
To create a new size chart we must specify the structure of its attributes, therefore, it is necessary to make a POST to the /domains/$domain_id/technical_specs?section=grids feature by uploading to the body all the attributes recognized when checking the product specification sheet of the domain with the grid_template_required tag.
There are three types of size charts: Brand(BRAND), Mercado Libre standard (STANDARD) or customized/specific (SPECIFIC).
In Uruguay, Colombia, Peru, Ecuador and Chile we will only have the custom/specific (SPECIFIC) type of size chart experience.

}When checking the product specification sheet of size charts in TOPS and BOTTOMS domains, a list data type will be found, which establishes the possible values of a List. These values must be taken into account when creating a customized size chart in these domains.

]Additionally, for TOPS and BOTTOMS< domains it is allowed to create size charts specifying body measures or clothes sizes, in both cases you will be able to recognize them from the data sheet by means of BODY_MEASURE or CLOTHING_MEASURE tags.
Example of GARMENT_LENGTH_FROM attribute used in clothes sizes:
"attributes": [
{
"id": "GARMENT_LENGTH_FROM",
"name": "Largo de la prenda desde",
"value_type": "number_unit",

},

"name": "cm"
}
],
"hierarchy": "CHILD_DEPENDENT",
"relevance": 3
}
]Size chart search
With the /catalog/charts/search feature it is possible to make a POST and recognize the suggested size charts to be used by the seller in their listings.
Request:
curl -X POST -H 'Authorization: Bearer $ACCESS_TOKEN' -H "Content-Type: application/json" -d {...} https://api.mercadolibre.com/catalog/charts/searchExample for a search of available size charts of adidas BRAND type for Women in the SNEAKERS domain:
curl -X POST 'https://api.mercadolibre.com/catalog/charts/search' -H 'x-caller-id: 123456' -H 'Content-Type: application/json' -H 'Authorization: Bearer $ACCESS_TOKEN' --data-raw '{
"domain_id": "SNEAKERS",
"site_id": "MLA",
"seller_id": 123456,
"attributes": [
{
"id": "GENDER",
"values": [
{
"name": "Mujer"
}
]
},
{
"id": "BRAND",
"values": [
{
"name": "adidas"
}
]
}
]
}'Before searching size charts it is necessary to take into account the attribute with the grid_template_required tag in the product specification sheet, which establishes the attributes of the POST. The dominio, site, seller are mandatory for all cases.
If the following is uploaded to the body of the POST:
Response:
As a response, all chart_id returned as a result of the search for charts according to the filters uploaded will be obtained.
{
"charts": [
{
"id": "426237",
"names": {
"MLA": "Guia de talles de calzado de mujer de adidas TEST APPAREL"
},
"domain_id": "SNEAKERS",
"type": "BRAND",
"main_attribute_id": "EU_SIZE",
"secondary_attribute_id": "F_US_SIZE",
"attributes": [],
"rows": []
},
{
"id": "426238",
"names": {
"MLA": "Guía de talles Standard de calzado de mujer TEST"
},
"domain_id": "SNEAKERS",
"type": "STANDARD",
"main_attribute_id": "AR_SIZE",
"secondary_attribute_id": "F_US_SIZE",
"attributes": [],
"rows": []
},
{},
{},
{},
{}
]
}
Likewise, you can use in the call the filter of the main_attribute_id attribute. For the following example we are using UZ_SIZE:
curl -X POST 'https://api.mercadolibre.com/catalog/charts/search' -H 'x-caller-id: 123456' -H 'Content-Type: application/json' -H 'Authorization: Bearer $ACCESS_TOKEN' --data-raw '{
"domain_id": "SNEAKERS",
"site_id": "MLA",
"seller_id": 123456,
"attributes": [
{
"id": "GENDER",
"values": [
{
"name": "Mujer"
}
]
},
{
"id": "BRAND",
"values": [
{
"name": "adidas"
}
]
}
]
}'If the search does not have suggested table results, the response you will get is as follows and you must first create size charts for the seller:
{
"charts": []
}
If you search with a domain that is not set up with the new size chart, there will be an error message.
{
"error": "domain_not_active",
"message": "Domain MLA-HATS_AND_CAPS is not active to be used in charts.",
"status": 400
}
Standard and Brand domains
This feature aims at informing the domains that currently have size charts created, either BRAND or STANDARD for a specific country and therefore the seller can use them in their listings.
You must upload to the body of the POST the type=BRAND or type=STANDARD filter and the corresponding country.
Request:
