# Pref-filled answers

## 👀 What are pre-filled answers ?

Pre-filled answers allows you to create a [deployment link URL](https://docs.ngsurvey.com/form-management/publish-deploy) that will pre-fill your survey with specific values. Once you share this link with your respondents ngSurvey will pre-fill the survey with the values that have been set in this link to select questions or fill fields. 

You may  either create manually pre-filled links or you can use the [preview / testing](https://docs.ngsurvey.com/form-management/form-designer/preview-testing) center to generate the link dynamically while you fill out the test survey.

{% hint style="info" %}
You may also set the default text value on your [answer properties](https://docs.ngsurvey.com/form-management/form-designer/answers/answer-properties) to set a default text that will fill your fields on the first time your respondents take the surveys.
{% endhint %}

## 🔗 Dynamic generation

To generate dynamically the link while you select the answers make sure to enable the generate **pre-filled answers url** property of the [preview / test center](https://docs.ngsurvey.com/form-management/form-designer/preview-testing). Once its enabled you will be able to see and copy the pre-filled link from the preview navigation toolbar.

ngSurvey will automatically build the link based on your actual test survey selections and entries.

##   ✍️ Manual generation

Advanced users may use the [web link](https://docs.ngsurvey.com/form-management/publish-deploy/web) and append manually the values that should be used to pre-fill the survey. 

Values should be added as a querystring name / value pair with following format 

a\_fieldansweridtofill=yourvalue\
q\_questiontoselect=answeridtoselectforthatquestion

In the sample below ngSurvey would  

1.  fill the survey answer field having an id of MBs6BnWERPH69EIEZiba with a value John.
2. select the question with id MBs63pNZnnxG7ctdYfIa with the answer having an id of MBs63pNZnnxG7ctdYfJa 

```

```

 You may find the answer id in the browser URL when you edit the [answer properties](https://docs.ngsurvey.com/form-management/form-designer/answers/answer-properties)
