Document and Face Validation

For information about this validation in WhatsApp flows, please visit How to Use WhatsApp to Validate Identity guide.

Then choose the method to reinforce with a proof of life:

Properties

Depending on the level of user experience and security you want to implement in the validation process, you can configure the Document ID + Face match validator.

Enable gallery upload: You can allow the user to upload a document from their gallery.
Check Type: Use this when you need to perform a Background Checks. You must use a Custom Type, which can be created using the dataset_document_validation key with a value of zero.
Threshold: This determines the required similarity between the provided picture and video or selfie to pass the validation, ranging from 0 to 1. By default, the threshold is set to 0.65. Note that a higher value may increase friction with the end-user, resulting in decreased customer conversion, while a lower value might increase conversion but reduce the rigor of the validation.
Allowed retries: This setting determines the number of times a user can retry a validation:
- Document Validation: With a maximum value of 3 retries. For more information about tips for capturing a good quality document picture, please refer to Document picture tips.
- Face Validation: Only enabled for video selfie, with a value of 2 retries by default and not configurable.
Allowed document types: You can select the document type and country, or ask the user to provide this information.
It is recommended to send the photo horizontally. JPEG, JPG and PNG are the only supported formats and the maximum allowed size is 30MB.

Additionally, using our API you can configure other parameters to improve the behavior of the validators and the user experience according to your particular needs. Please see the Config Validator Guide for more information on customization.

Please Note:

The config parameters you will see in the Config Validator Guide are global parameters for your account and will affect all the validations across your account.

However, validations performed using the flow you created will prioritize the configuration in the Validator Block of your flow. All other parameters, not configurable within the Flow Builder, will take the global configuration values.

Remember also you could customize your web flow. For more information please visit Customize Web Flow guide.
