Current event signature validation

This operation performs an event-based signature validation on a current event signature. Signature validation is performed within the current event window.

For this operation to succeed, the following administrative tasks should be performed in OneSpan Authentication Server:

1. Register the client application.
2. Define/assign a current event signature validation policy to this client application.
3. Define users and assign authenticators supporting event-based transaction authentication.

At a minimum, the authSignature command requires the following set of signature field attributes in order to perform signature validation:

• SIGNFLD_COMPONENT_TYPE
• SIGNFLD_USERID
• SIGNFLD_SIGNATURE

If the transaction authentication is successful, OneSpan Authentication Server will return the verified event counter in the SOAP response. This information will be specified by the SIGNFLD_VERIFIED_EVENT_VALUE signature attribute in the resultattribute element.
