Hidden Fields allow you to use data that you already have, to make your typeforms more personal, or simply to give you better data in your results.

Hidden Fields is a Professional plan (and above) feature. Find out more about Professional accounts here.

Hidden Fields can be used for lots of things:

• Track where respondents come from (social media channels, for example)
• Segment your audience for deeper insights and analysis
• Customize your typeform to make it even more personal

How do Hidden Fields work?

Hidden Fields allows you to place data that you already have directly in your typeform URL. You can view all your data in the Results panel.

What types of information can be passed with Hidden Fields?

You can include any information you want, for example:

• The person’s name (so that you can use Recall Information to welcome each respondent personally)
• The email of your respondent (so you know who completed the typeform)
• Traffic source (so that you know where someone saw your typeform – Facebook, website etc)
• If you sell shoes, you can even capture the person’s shoe size so you always have that information stored for future transactions through your typeforms

 

How to add Hidden Fields to your typeform

1. Open your typeform from your workspace. On the left panel, click Logic, then Advanced. You can now see the Hidden Fields area:

2. Click Hidden Fields, and a new field will open where you can add your Hidden Fields:

3. Click the + Add Hidden Field, then type in what you want to call it:

Click the + button again to add more Hidden Fields as required, then hit Save.

Whatever you write for your Hidden Fields, they’ll be converted to lower-case letters automatically.

4. Your Hidden Fields will be added to your typeform's share URL, once you have published it. To see them, head to the Share panel:

Click Copy link, then you can paste it wherever you like. If you want to add information to the Hidden Fields manually, you can do this by pasting your link, and replacing the xxxxx with the word you want.

My Hidden Field is for tracking the source of my respondents, so I would change xxxxx to "twitter" or "facebook" for sharing on those networks.

Hidden Fields breakdown

If you add Hidden Fields to your typeform, a string of characters called “query strings” will be added to the URL of the typeform. Here is an example of query strings:

https://tutorials.typeform.com/to/nzthWI#name=xxxxx&source=xxxxx

In this example we are placing two parameters into two distinct Hidden Fields, these are:

• name
• source

Using our example above, if Fran was sent their typeform through Twitter, then the URL would look like this:

https://tutorials.typeform.com/to/nzthWI#name=Fran&source=twitter

Now your typeform will automatically fill your Results with the following data:

• name: fran
• source: twitter

And you won’t have to ask for their data using a question in the typeform. How cool is that?

You can pass text in the Hidden Field with a space. This can come in handy when passing, for instance, full names, like “Jane Doe”. You need to replace the spaces with “%20” in the URL in order for the Hidden Field to appear with the space in your Results and / or typeform. So your URL would look like this:

https://example.typeform.com/to/AbCdEf#fullname=Jane%20Doe

And that is not all, you can encode any character using UTF-8 percent encoding.

How do you make this work?

There are 2 ways to implement this feature:

Manually – you manually add information to the Hidden Fields in the URL before sharing your typeform.

Automated – you can use your CRM system (Salesforce, Infusionsoft, Netsuite, etc.) to populate your data, so up to thousands of people can receive a custom URL Typeform. Please read these articles for more details:

Using Hidden Fields with embedded typeforms.

You can easily add a Hidden Field like “source” to a typeform that’s already embedded, but remember that this changes the URL of your typeform.

You need to paste in the new embed code you find in the Share panel, and edit it manually:

Let’s say you want to track the source – where people complete your typeform. Paste the code from the Share panel into your website, then change the ‘xxxxx’ to read whatever you want, like ‘homepage’ or ‘web’, for example.

Now you’ll be able to see in your Responses how many respondents answered your typeform from your website!

 

What will it look like when I collect data?

Data from Hidden Fields will appear in your Results Summary and Responses.

In your Summary, you can see all the results that came through with data from Hidden Fields:

In your Responses tab, you can see each individual submission and its Hidden Field data:

Give it a shot. Copy this link, paste it in a web browser and replace the “xxxxx” with your name and an imagined source, like ‘facebook’. Then hit ‘enter’ and see what the typeform does.

How to use the collected Hidden Fields information in your typeform

Apart from passing data into your Results, you can do two more things with Hidden Fields:

• Add Hidden Fields to a question in your typeform. Find out how in this article: Recall Information
• Use Recall Information to create Logic Jumps. Refer to this article to learn more: How to set Logic Jumps?
