New Timestamp Fields in 3DS Authentications and Backtests

Overview

3DS authentications now include an updated timestamp, and the three_ds_authentication.challenge webhook now includes a created timestamp. Authorization Rules backtest results now include a created timestamp. Card programs can use these fields to order events, detect changes to an authentication, and measure the time between steps of a 3DS flow.

Details

3DS Authentication Object

The 3DS authentication object has a new updated field. It holds the date and time when Lithic last updated the authentication. The value is equal to created until the authentication is updated, for example when a challenge is completed. The field is always present and uses the ISO 8601 format yyyy-MM-dd'T'hh:mm:ssZ.

The authentication object appears in these payloads, so all of them carry the new field:

• three_ds_authentication.created webhook
• three_ds_authentication.updated webhook
• three_ds_authentication.approval_request decisioning request
• authentication_object in the three_ds_authentication.challenge webhook
• GET /v1/three_ds_authentication/{three_ds_authentication_token} response

3DS Challenge Webhook

The three_ds_authentication.challenge webhook has a new top-level created field. It holds the date and time when Lithic emitted the challenge event. The field is always present and uses the ISO 8601 format yyyy-MM-dd'T'hh:mm:ssZ.

Backtest Results

Backtest results have a new created field. It holds the date and time when the backtest was requested. The field is always present and uses the ISO 8601 date-time format.

Backtest results appear in these payloads, so both of them carry the new field:

• GET /v2/auth_rules/{auth_rule_token}/backtests/{auth_rule_backtest_token} response
• auth_rules.backtest_report.created webhook
