GET parameters in the URL

You can use GET parameters to add attributes to the form URL. Using the GET parameters, you can automatically fill in the fields of the form that you publish by link or embed on the page using an iframe, for example:

To set up pre-filling of form fields:

1. Get the question ID and answer option ID (for multiple-choice questions).

2. Add a question mark (?) and the parameter to the form URL. The parameter format depends on the question type:

   • For questions with an input field, such as Short text or Email:

     <question_ID>=<answer_text>
     

     If there are multiple words in the answer, replace the spaces with a + sign. For example:

     https://forms.yandex.com/u/5e2ac2d850bdb705********/?answer_short_text_1685088=Planet+Earth
     

   • For questions with answer options, such as One answer or Multiple answers:

     <question_ID>=<answer_ID>
     

     For example:

     To choose one answer option:

     https://forms.yandex.com/u/5e2ac2d850bdb705********/?answer_choices_1685184=1958524
     

     To add a second answer option, add the & symbol and specify the question ID and the second answer option ID again:

     https://forms.yandex.com/u/5e2ac2d850bdb705********/?answer_choices_1685184=1958524&answer_choices_1685184=1958526
     

   • For Date questions:

     <question_ID>=YYYY-MM-DD
     

     For example:

     https://forms.yandex.com/u/5e2ac2d850bdb705********/?answer_date_1685200=2020-01-27
     

   • For Yes/No questions:

     <question_ID>=True
     

     For example:

     https://forms.yandex.com/u/5e2ac2d850bdb705********/?answer_boolean_1685199=True
     

   • For Rate on a scale questions.
     Choose an answer by one criterion:

     <question_ID>=<answer_ID>
     

     Choose an answer by multiple criteria:

     <question_ID>[<X_criterion_ID>]=<X_response_ID>&<question_ID>[<Y_criterion_ID>]=<Y_response_ID>
     

     For example:

     https://forms.yandex.com/u/5e2ac2d850bdb705********/?answer_choices_1686274=231035_231038
     

     https://forms.yandex.com/u/5e2ac2d850bdb705********/?answer_choices_1686274[231034]=231034_231037&answer_choices_1686274[231035]=231035_231038
     

3. To fill in multiple form fields at once, add multiple GET parameters separated by &.

   https://forms.yandex.com/u/5e2ac2d850bdb705********/?answer_short_text_1685088=John+Smith&answer_choices_1685184=1958524
