initialize

POST /api/v1/zoloz/idrecognition/initialize

The ZOLOZ initialize API is used to initialize the ID recognition process in ZOLOZ. A unique transaction ID is generated for the ID recognition process and used in all the subsequent interactions with the ZOLOZ server. This API is not idempotent.

Structure

Request parameters

Field name

Data type

Max length

Description

bizId

String

32

Required. A unique business ID for tracing purpose. For example,the sequence ID from the merchant's business-related database.

Note: The ZOLOZ server does not perform uniqueness check on the value of this field. For better tracking, it is strongly recommended to enable the merchant server to guarantee the uniqueness of the business ID.

metaInfo

String

512

Required. The meta information about the SDK and the user's device. The value of this field is returned from the ZOLOZ SDK in the JSON string format, for example:

"{\"apdidToken\":\"69b74bfe-bf7f-4d3b-ac59-907ee09e7955\",\"appName\":\"com.zoloz.atomic.client\",\"appVersion\":\"1.0.9\",\"bioMetaInfo\":\"3.46.0:2916352,0\",\"deviceModel\":\"MI 6\",\"deviceType\":\"android\",\"osVersion\":\"9\",\"zimVer\":\"1.0.0\"}".

Note: Do not modify the returned value as it only needs to be passed through directly.  

userId

String

64

Required. Merchant user ID, or other identifiers that can be used to identify a specific user, for example, mobile phone number, email address and so on.  It is strongly recommended to pre-desensitize the value of the userId field, for example, by hashing the value. 

docType

String

16

Required. Type of the document, for example, if the document to be uploaded is a passport, set the value of this attribute to 00000001003. The value of this field must not be null or an empty string. For the document types that are supported, see Document types supported and OCR results returned

pages

String

32

Optional. The document pages that you want to do id recognition. Use comma to separate. For the document page range, see Document types supported and OCR results returned

serviceLevel

String

32

Optional. Three levels are supported:

  • IDRECOGNITION0002 (default): basic anti-spoofing, which only captures a normal photo of the document.
  • IDRECOGNITION0003: flashlight anti-spoofing. If this value is set, the ZOLOZ SDK automatically scans the identity document. The ZOLOZ server performs advanced spoofing checks. This level shall only be used in native SDK, as web SDK has technical limitations in operating the flashlight. If it is used in web SDK, the behaviour is unpredictable.
  • IDRECOGNITION0005: multi-angle anti-spoofing. This level shall only be used in web SDK, the behaviour is unpredictable when used in native SDK. As of now, this level only supports HK identity cards, other document types may be supported in future when needed.

h5ModeConfig

Object

Optional. Specifies the configuration settings for H5 ID Recognition flow. For more information,see h5ModeConfig

allowExpiredDocument

String

Optional. Specifies whether expired documents are allowed. The following values are supported, : 

  • Y: Allow expired documents. This is the default value for all documents except Passport (docType=00000001003).
  • N: Pause ID Recognition process when an expired document is detected. This is the default value for Passport (docType=00000001003).

Notes:

  • Different document types have different default values,
  • Invalid values will fall back to the default option and pause the Real ID process when an expired document is detected.

Response parameters

Field name

Data type

Description

result

Result

Required. The API request result, which contains information about the result of the API request, such as status and error codes. 

transactionId

String

Optional. A unique transaction ID that is generated by the ZOLOZ server for the ID recognition process. This ID will be used as an input parameter for the ID recognition checkresult API request.

Note: when an error occurs during the process, for example, invalid argument, no transaction ID is returned.

clientCfg

String

Optional. The client configuration information, including parameters about SDK connection and behavior. The value of this field is specified only when the result.resultStatus field is "S". 

Result

Result process logic

For different request results, different actions are to be performed. See the following for details:

  • If the value of the result.resultStatus is S , the ZOLOZ initialize API is invoked successfully and a unique transaction ID is returned.
  • If the value of the result.resultStatus is F , the invocation of the ZOLOZ initialize API fails. Check the error code and message for more information about the possible reasons. Error codes

Common error codes

For the full list of common error codes, see the Common error codes section in the Error handling topic.

API-specific error codes

The following table shows the possible error codes that are specific for the ID Recognition initialize API.

Sample

Request sample

For different integration modes, the request structures are a little different. When the ID recognition process is initiated in the H5 mode, additionally, an object called h5ModeConfig must be specified. Refer to the following two request samples for the detailed information.
