Just wondering, since it was me who made the implementation for the Why not follow the same pattern for 3RI? This seems like going back to the old setup more or less. |
The sandbox docs had no 3RI section, and the last-4 message-version rule read as browser-only. Document that 3RI (deviceChannel 03) uses the same last-4 PAN encoding as the browser channel, so integrators can drive 2.1.0 / 2.2.0 / 2.3.1 on any scheme PAN by varying the last four digits. - Add a "3RI Tests" section describing the shared last-4 encoding: first digit selects the message version, third+fourth select the ARes outcome. - 3RI is frictionless only: document the available outcomes (Y/N/A/R/U + DS timeout) and that challenge/decoupled/information-only combinations are rejected for deviceChannel 03. - Clarify in the browser "Message version" section that the last-4 encoding is shared with 3RI (not browser-only). - Cross-link the Basic 3RI Example to the new 3RI test-card section. - Fix the browser version table: 2.3 -> 2.3.1 (the sandbox serves 2.3.1).
