Document Validation via API

Product: Validators

Learn how to perform a document validation using our API, understanding the essential API endpoints, responses and errors.

Prerequisites

Before you begin, make sure you have the following:

  1. Truora API-Key: This key grants access to our services. If you don’t have one already, set up an account and then go to Authentication to obtain your Truora API-key.

  2. A valid ID: You’ll need a valid identification document to run the document validation.

  3. Postman: Use Postman or any other collaboration tool for API development. Although it is not required to perform the integration, it will help perform tests along the way.

Truora provides a Postman collection online that includes the necessary tools to simplify the testing process.

1. Create validation

Setup main Request Headers and Body

To configure the main request headers and body, follow these steps:

  1. Create a POST request to the endpoint https://api.validations.truora.com/v1/validations.
  2. Set the Headers
    • Truora-API-Key: enter the value obtained in the step of get Truora API-key.
    • Content-Type: the value should be application/x-www-form-urlencoded.
  3. Set required values for the request body
    • type [Required]: Indicates the type of validation to be performed. Set this value to document-validation
    • user_authorized [Required]: This indicates that you have the authorization of the person to be verified. This is mandatory in order to comply with data protection laws. Value must be set to true in order to perform the validation.
    • country [Required]: Allowed: CO |CL | MX| PE | BR | CR | VE | PA | ALL. Set the country of the document being validated.
      Use ALL when document_type is set to passport.
      For BR,CR, VE, PA please ask sales team.
    • document_type [Required]: Allowed: national-id | foreign-id | driver-license | passport | identity-card| rut | ppt | invoice | picture-id | record | cnh . Set this value to the type of document been validated. For ppt please ask sales team.
      Refer to Appendix 1: Supported Document Types for a complete reference of supported document types, applicable countries and document front/reverse picture requirements.
    • account_id [Optional]: Unique user identifier for tracking validations of a user.*
    • alias_id [Optional]: The alias identifier linked to an existing account_id. Omit the account_id when using the alias_id instead. See the Aliases Guide for more details.
    • custom_type [Optional]: When specified, indicates the name of the custom type check when a background check linked to this validation is desired.**
    • retry_of_id [Required if you have active retries and want to retry a previous validation]: Refers to the validation_id of the failed validation.

*Only Account IDs following the regex pattern [a-zA-Z0-9_.-]+ are supported. While optional, it’s recommended to provide a unique identifier for accurate monitoring and data isolation between users. Utilize a library for managing user identifiers (User ID) based on your programming language or development framework. Avoid using repetitive number sequences. If left empty, an automatic account_id will be generated. Please go to Create an Account ID to learn more about it.

** Every time you run a document validation our system runs a default Background check (no extra charge), which will only verify datasets related to identity and excludes criminal, legal, international or any other dataset types. If you wish customize the default behavior, use this field to conduct a Background Check with a Custom Type.

  • Note 1: You must have enabled the background check (BGC) product to use Custom Type. For each document validation request with a custom background check, you will be charged for it with the BGC price.
  • Note 2: If you create a Custom Type, you must add the dataset dataset_document_validation key with a value of zero.
  • You will identify within the Get Validation response that a check_id has been created.

Send the Create validation request you just created. You will receive a response similar to the following:

POST
/v1/validations 

    {
        "validation_id": "VLDXXXXXXXXXXXXXXXXXXXXXXXXXX",
        "ip_address": "186.168.XXX.XXX",
        "account_id": "ACCXXXXXXXXXXXXXXXXXXXXXXXXXX",
        "type": "document-validation",
        "validation_status": "pending",
        "creation_date": "2024-04-16T15:11:21.102178964Z",
        "instructions": {
            "front_url": "https://file.upload.url/TCI70HXSXXXXXXXXXXXXXXXXXX/ACCXXXXXXXXXX/CO/national-id/DCRXXXXXXXXXXXXXXXXXXXXXX_front.png?max-size=31457280&method=PUT&retries=1&token=3f4a03ce085ca32380b8653e24c6e1f379f599fac05e2f9241411625930a36ac&Expires=1713280581&Signature=eFPiClflEer4rzLRIxPbw5Ht2-A8nbGM4pVhP3wQoafxdLLi1E-asUBHMsKwYytB3FCfIXywIVQqZ3c0THwvgtmtiI62tQXa183LdvUbSRpHPRD3FmR6nu7SnrpjHwl2oq6WnOUiwOjupcngmBKzXFgAS2QdNOL-nAj310kYzSA~OqIuIxjv6cRdwi3gVwdnbUw4UDAb2nD7GWOTROdEib8dUR3z6KJtTSi1DQUzqDP1TmYnwX~erpaWN5nVUEU3chOsxHEQfPUeKRxIEGjiTMz-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX__&Key-Pair-Id=APKXXXXXXXXXXXXXXXXXXX",

        }
    }
Among other details, the following information may be identified in the response:

  • validation_id: Unique identifier of the validation.

  • account_id: Unique identifier of the user.

  • type: Type of validation performed.

  • validation_status: The current status of the validation will be pending until the images are submitted. After performing the validation, the status could change to:

    - success: Indicates a successful validation.
    - failure: Indicates an unsuccessful validation or may also occur due to an internal error.

  • creation_date: Date and time of validation creation.

  • front_url: URL where the image of the front side of the identification document should be sent.

  • reverse_url: URL where the image of the reverse side of the identification document should be sent.

2. Upload document picture

Images must be submitted through a PUT request to the URLs generated in the previous step, front_url and reverse_url, selecting the Binary type in the Body. Make the following requests to upload the front and back of the document:

  • PUT {{front_url}}: Upload the front document picture by making a PUT request using the URL returned from the Create validation step.

  • PUT {{reverse_url}}: Upload the reverse document picture by making a PUT request using the URL returned from the Create validation step.

    NOTE 1: It is recommended to upload the document photo horizontally. For more information on how to take a good picture of the document, please visit the Tips for document photo section.

    • Supported formats are JPEG, JPG and PNG, with a maximum allowed size of 30MB.
    • PDF format is allowed when document_type is set to invoice (Only allowed for Mexico).

    NOTE 2: Not all document types will requiere both front and reverse pictures. Please refer to Appendix 1: Supported Document Types for a complete reference of supported document types, applicable countries and document front/reverse picture requirements.

Once the document picture is successfully uploaded, the response code for each of these requests should be 200, as follows:

PUT
{{front_url}} 

{
    "code": 10200,
    "http_code": 200,
    "message": "Successfully uploaded"
}
PUT
{{reverse_url}} 

{
    "code": 10200,
    "http_code": 200,
    "message": "Successfully uploaded"
}

3. Get Validation

The Get validation request allows you to retrieve the current status and results of a validation. The validation_status begins as pending. Upon completion, the validation can either be success or failure.

  • To obtain the validation results, send a GET request to the endpoint https://api.validations.truora.com/v1/validations/{{validation_id}}, where validation_id is the identifier returned in the Create validation request.
  • If you want to obtain links the document pictures, use the query parameter show_details with the value of true in the request.

Once executed, if the validation is still processing, validation_status will be pending and you will receive a response similar to the following:

GET
/v1/validations/{{validation_id}} 

{
    "validation_id": "VLDXXXXXXXXXXXXXXXXXXXXXXX",
    "ip_address": "186.168.XXX.XXX",
    "account_id": "ACCXXXXXXXXXXXXXXXXXXXXXXXXX",
    "type": "document-validation",
    "validation_status": "pending",
    "creation_date": "2024-04-16T19:40:38.133594051Z",
    "attachment_status": "pending"
}

When the validation is completed successfully, validation_status will be success and you will receive a response similar to the following:

GET
/v1/validations/{{validation_id}} 

{
    "validation_id": "VLDXXXXXXXXXXXXXXXXXXXXX",
    "ip_address": "186.168.XXX.XXX",
