Barcodes Reader

`POST /v1/barcode/read/from/url`

Attributes

Attributes are case-sensitive and should be inside JSON for POST request. for example: { "url": "https://example.com/file1.pdf" }

Attribute	Type	Required	Default	Description
`url`	string	Yes	-	URL to the source file `url` attribute
`callback`	string	No	-	The callback URL (or Webhook) used to receive the POST data. see Webhooks & Callbacks. This is only applicable when `async` is set to `true`.
`httpusername`	string	No	-	HTTP auth user name if required to access source URL.
`httppassword`	string	No	-	HTTP auth password if required to access source URL.
`pages`	string	No	all pages	Specify page indices as comma-separated values or ranges to process (e.g. “0, 1, 2-” or “1, 2, 3-7”). The first-page index is 0. Use ”!” before a number for inverted page numbers (e.g. “!0” for the last page). If not specified, the default configuration processes all pages. The input must be in string format.
`async`	boolean	No	`false`	Set `async` to `true` for long processes to run in the background, API will then return a `jobId` which you can use with the Background Job Check endpoint. Also see Webhooks & Callbacks
`type`	string	Yes	QRCode	Set the barcode type to be used. See available barcode types in the Supported Barcode Types
`types`	string	No	-	Detects checkboxes, radiobuttons, vertical and horizontal lines, and general segments (all content types) on scanned documents using the barcode reader engine. Comma-separated list of object types to decode, must be in a string format.
`profiles`	object	No	-	See Profiles for more information.
`DataEncryptionAlgorithm`	string	No	-	Controls the encryption algorithm used for data encryption. See User-Controlled Encryption for more information. The available algorithms are: `AES128`, `AES192`, `AES256`.
`DataEncryptionKey`	string	No	-	Controls the encryption key used for data encryption. See User-Controlled Encryption for more information.
`DataEncryptionIV`	string	No	-	Controls the encryption IV used for data encryption. See User-Controlled Encryption for more information.
`DataDecryptionAlgorithm`	string	No	-	Controls the decryption algorithm used for data decryption. See User-Controlled Encryption for more information. The available algorithms are: `AES128`, `AES192`, `AES256`.
`DataDecryptionKey`	string	No	-	Controls the decryption key used for data decryption. See User-Controlled Encryption for more information.
`DataDecryptionIV`	string	No	-	Controls the decryption IV used for data decryption. See User-Controlled Encryption for more information.

Query parameters

Responses

Parameter	Type	Description
`barcodes`	array[object]	List of barcodes found in the document
`pageCount`	integer	Number of pages in the PDF document.
`error`	boolean	Indicates whether an error occurred (`false` means success)
`status`	string	Status code of the request (200, 404, 500, etc.). For more information, see Response Codes.
`credits`	integer	Number of credits consumed by the request
`remainingCredits`	integer	Number of credits remaining in the account
`duration`	integer	Time taken for the operation in milliseconds

types

Detects checkboxes, radiobuttons, vertical and horizontal lines, and general segments (all content types) on scanned documents using the barcode reader engine.

Comma-separated list of object types to decode, must be in a string format.

Visual Element Detection Modes

Checkbox: Locates check boxes.
Segment: Locates and selects objects on a page (general selection).
UnderlinedField: Detects fillable fields (typically, underlined spaces, i.e. fields to fill in a form).
Rectangle: Detects rectangles, including checkboxes. Also returns the value as 1 if a checkmark or a filled rectangle was detected.
Oval: Detects rounded or oval marks (typically, a radiobutton). Returns value of 1 if filled out radiobutton was detected.
HorizontalLine: Detects horizontal lines.
VerticalLine: Detects vertical lines.
