Convert product barcodes to Amazon ASINs

The POST /tools/convert/barcode-to-asin endpoint converts barcodes to Amazon Standard Identification Numbers (ASINs). Because the same product can appear under different ASINs in different Amazon marketplaces, each barcode maps to an array of objects — one per ASIN and locale combination found.

Endpoint

POST /v1/tools/convert/barcode-to-asin

Request body

array of strings

required

The barcodes to convert. Each element must be a valid numeric barcode string.

{
  "data": [
    "8806095074122",
    "0887276760049"
  ]
}

Example request

curl --request POST \
  --url 'https://api.affiliate.com/v1/tools/convert/barcode-to-asin' \
  --header 'Authorization: Bearer {your_api_key}' \
  --header 'Content-Type: application/json' \
  --data '{
    "data": [
      "8806095074122",
      "0887276760049"
    ]
  }'

Example response

{
  "meta": {
    "from": "barcode",
    "to": "asin",
    "from_total": 2,
    "to_total": 1,
    "trace_id": "0196f461-079d-73c5-9c4e-aab8c4834d53"
  },
  "data": {
    "8806095074122": [
      {
        "asin": "B0C792QRW6",
        "locale": "us"
      }
    ]
  }
}

In this example, 8806095074122 resolves to ASIN B0C792QRW6 in the us locale. Barcode 0887276760049 is absent from data because no matching ASIN was found — to_total reflects only the barcodes that produced results.
