Consult fiscal data by item/variation
You can also search for the information linked to a publication in Mercado Libre:
Request:
curl -X POST -H 'Authorization: Bearer $ACCESS_TOKEN' -H "Content-Type: application/json" -d
{
"query": "query getFiscalInformationsByItem($itemId: String!, $defaultDataIfNotExists: Boolean, $allVariations: Boolean) {\n getFiscalInformationsByItem(itemId: $itemId, allVariations: $allVariations, defaultDataIfNotExists: $defaultDataIfNotExists) {\n itemId\n variationId\n type\n components {\n sku\n quantity\n percentageShare\n fiscalInformation {\n ... on FiscalInformationMLC {\n sku\n iva\n description\n ila\n retention\n taxCode\n taxDescription\n }\n }\n }\n }\n}",
"variables": {
"itemId": "String",
"allVariations": true,
"defaultDataIfNotExists": true
}
}
https://api.mercadolibre.com/fiscal_information/graphql
Example:
curl -X POST -H 'Authorization: Bearer $ACCESS_TOKEN' -H "Content-Type: application/json" -d
{
"query": "query getFiscalInformationsByItem($itemId: String!, $defaultDataIfNotExists: Boolean, $allVariations: Boolean) {\n getFiscalInformationsByItem(itemId: $itemId, allVariations: $allVariations, defaultDataIfNotExists: $defaultDataIfNotExists) {\n itemId\n variationId\n type\n components {\n sku\n quantity\n percentageShare\n fiscalInformation {\n ... on FiscalInformationMLC {\n sku\n iva\n description\n ila\n retention\n taxCode\n taxDescription\n }\n }\n }\n }\n}",
"variables": {
"itemId": "MLC1056231867",
"allVariations": true,
"defaultDataIfNotExists": true
}
}
https://api.mercadolibre.com/fiscal_information/graphql
Response:
{
"data": {
"getFiscalInformationsByItem": [
{
"itemId": "MLC1056231867",
"variationId": "175219804700",
"type": "SINGLE",
"components": [
{
"sku": "DOCMLC1",

"ila": "",
"retention": "14",
"taxCode": "14",
"taxDescription": "Para Facturas de venta del contribuyente."
}
}
]
}
]
}
}
These are the possible ways of doing the search:
- itemId: when the publication has no variation.
- itemId + variationId: when the publication has a variation, to obtain the data only of the requested variations.
- itemId + allVariations: when the publication has variation, to obtain the data of all the variations of this publication.

Request:
curl -X POST -H 'Authorization: Bearer $ACCESS_TOKEN' -H "Content-Type: application/json" -d
{
"query": "mutation updateFiscalInformationMLC(\n $where: UpdateFiscalInformationMLCWhere!\n $input: UpdateFiscalInformationMLCInput!\n) {\n updateFiscalInformationMLC(where: $where, input: $input) {\n sku\n iva\n description\n retention\n ila\n taxCode\n }\n}",
