External Reference Variable is an another variable which can be used to pass in data to the Survey. The External Reference variable (i.e. ext_ref) is used to associate responses to their respondents. You can assign an ID number or anything else that will uniquely identify a respondent to the ext_ref variable. When the results are collected the ext_ref variable is captured and stored with the other data.

Every survey that you create will have a unique URL. To include other data to be captured along with the survey data you just need to add the ext_ref parameter to the URL. For example: https://questionpro.com/t/AIZBjs6?ext_ref=xxxx Replace xxxx with your unique id for the respondent.

The ext_ref parameter can be passed along with the URL in the following format: For Example: The URL for the survey is: https://test.questionpro.com The ext_ref tag is appended as follows: https://test.questionpro.com/?ext_ref=xxxx

The External Reference Variable can store up to 64 characters. You can use Alphanumeric Characters (A to Z, a to z, 0 to 9). Accented characters or characters from languages other than English may not get saved. Please limit the character use to English. You cannot use the Pound/Hash [#] in the External Reference Variable We recommend you not to use Comma and Quotes in the ext_ref/custom variable.

If you are using the Email/List Management interface to send out email add the following tags to your survey invitation: <SURVEY_LINK>&ext_ref=xxxx <ANONYMOUS_SURVEY_LINK>&ext_ref=xxxx The &ext_ref variable is automatically captured in the raw response data.
