Collecting User Data

Using Question Placeholders in project_url

The project_url field supports question ID placeholders, which allow Prodege to dynamically insert a respondent’s answers into your survey URL. Supported question IDs can be found in the /lookup-question-by-country endpoint.

Placeholder Syntax

Question placeholders use the following format:

%q[question_id]%

When the URL is generated, each placeholder is replaced with the respondent’s corresponding option_id.

Example: Single-Select Question

If you want Prodege to pass a respondent’s gender (question ID 3) into your survey URL, you would include the following placeholder:

http://www.yoursurvey.com?your_var_name=%q3%&transaction=%transid%

If the respondent’s answer to question 3 is Male, and the corresponding option_id is 1, the final URL will be:

http://www.yoursurvey.com?your_var_name=1&transaction=145187

Example: Multi-Select Question

For multi-select questions (for example, question ID 20: What languages do you speak?), multiple answers are returned as a comma-separated list.

Original URL:

http://www.yoursurvey.com?your_var_name=%q20%&transaction=%transid%

If the respondent selected English and Spanish, with option IDs 1 and 2, the final URL will be:

http://www.yoursurvey.com?your_var_name=1,2&transaction=145187

Additional Notes

• You may include multiple question placeholders in a single project_url

• The entire project_url field is limited to 2,000 characters, including all placeholders and parameters
