Platform Redirect Guides

Use this reference when programming entry links and return redirects for your survey platform. All platforms must capture [%RDUD%] from the entry link and pass it back on every redirect.

As of October 1, 2024, surveys must use the RDUD respondent identifier. Legacy RID placeholders are not supported for new projects.

Generic redirect structure

Outcome	inbound_code	URL
Complete	1000	`https://www.rdsecured.com/return?inbound_code=1000&rdud=[RETURN_RDUD_VALUE_HERE]`
Terminate	2000	`https://www.rdsecured.com/return?inbound_code=2000&rdud=[RETURN_RDUD_VALUE_HERE]`
Security	3000	`https://www.rdsecured.com/return?inbound_code=3000&rdud=[RETURN_RDUD_VALUE_HERE]`
OverQuota	4000	`https://www.rdsecured.com/return?inbound_code=4000&rdud=[RETURN_RDUD_VALUE_HERE]`

Replace [RETURN_RDUD_VALUE_HERE] with your platform’s syntax for the captured RDUD value.

Entry link

Your survey URL must begin with https:// and include the RDUD placeholder:

https://your-survey-platform.com/survey/123?rdud=[%RDUD%]
