Barcode Recognition

Detects and decodes 1D and 2D barcodes in an image that you provide.

The Barcode Recognition API detects barcodes from an image. For each recognized barcode, it returns the type, the decoded barcode value, and the coordinates of the corners of a box that surrounds the barcode.

Quick Start

The Barcode Recognition API accepts an image as input, as either a file, a URL, or a Haven OnDemand reference (created by adding the file by using the Store Object API.

/1/api/[async|sync]/recognizebarcodes/v1?file= or reference= or url=

For a list of file formats that you can use for images, see Supported Media Formats.

The following curl request posts the productimage.jpg file to the API:

curl -X POST -F "file=@productimage.jpg"

The API recognizes any barcodes in the image, and returns the type of the barcode, the text value of the barcode, and the location of the barcode in the image. It provides the location as the coordinates of the upper left corner of a box that surrounds the barcode, and the width and height of the box.

For EAN-13 and UPC-A type barcodes, the API also returns the GS1 country code of the barcode as additional information.

  "barcode": [
      "text": "5000108030539",
      "barcode_type": "ean-13",
      "left": 295,
      "top": 634,
      "width": 515,
      "height": 263,
      "additional_information": {
        "country": "United Kingdom"

Barcode recognition is most reliable for approximately horizontally or vertically aligned barcodes (up to 20° rotation), although in some cases detection works for all alignments up to 45°. The image must also be high contrast, and preferably two-tone (black and white).

The Barcode Recognition API recognizes barcodes with the following formats:

  • EAN-13 (includes ISBN)
    Note: The EAN-13 barcode type is a superset of the UPC-A type, so the API returns the EAN type, rather than the UPC value. To find the UPC value, remove the leading 0 from the EAN value.
  • EAN-8
  • EAN-2 (includes ISBN-2)
  • EAN-5 (includes ISBN-5)
  • Codabar
  • Code-128
  • Code-39
  • Code-93
  • Datalogic 2/5
  • Data Matrix
  • IATA 2/5
  • Industrial 2/5
  • Matrix 2/5
  • Patch Code (or Patch)
  • PDF417
  • UCC/EAN-128 (or GS1-128)
  • UPC-A
  • UPC-E
  • QR Code

This API returns a JSON response that is described by the model below. This single model is presented both as an easy to read abstract definition and as the formal JSON schema.

Asynchronous Use

Additional requests are required to get the result if this API is invoked asynchronously.

You can use /1/job/status/<job-id> to get the status of the job, including results if the job is finished.

You can also use /1/job/result/<job-id>, which waits until the job has finished and then returns the result.

This is an abstract definition of the response that describes each of the properties that might be returned.
