Plan unique respondent codes
A unique-code workflow needs generation, assignment, and validation. A hidden field only carries a supplied value.
Select a screenshot to enlarge it.
Steps
- Choose a system that issues codes and defines uniqueness, expiry, and any single-use rule.
- If a code reference should accompany a form response, create a hidden field and add the encoded reference to the actual respondent link.
Definitions identify the fields expected in the respondent URL. Supply harmless URL-encoded values when testing. Use the current respondent URL rather than a builder URL. - Test duplicate, missing, expired, and modified codes against the issuing system before using them for access or rewards.
Check before you rely on it
An editable URL parameter is not a secure voucher or identity check.
If you need help
Automatic code generation and redemption are not established by adding a field named code. Confirm the integration you need.
