    Creating an Online Form for an Existing PDF

  • Custom Domain

    With Builder you can build three types of forms: online web forms, online PDF forms, and master forms.

  • Master Form Builder

    you will arrive at the Form Builder. On the form Builder, there are three main sections:

Custom form URL

In PlatoForms, each published form has its own unique web link that starts with “”. By sharing this link, others can easily access and fill out your online form in their web browser.

URL for published domain
Example URL for a published form

With a premium plan, you can personalize your form link, like “”. Once it’s set up, all your team’s published forms will have this custom URL (e.g.,


If you’re using the Embed Script for your form, a custom domain isn’t necessary. The forms blend seamlessly with your website’s domain through the script, so no extra setup is required.

Before you begin

Before you begin setting up a custom domain for your forms, ensure you have the following:

  • Domain name: You’ll need to register a domain through services like GoDaddy, Namecheap, or Google Domains.
  • Access to DNS records: It’s important to have access to your domain’s DNS records to make the required changes and connect your custom domain to your forms.

Set up custom domain

  1. Login to your PlatoForms account.

  2. In the left navigation, click your team name.

  3. From the expanded dropdown menu, select Custom Domain.

  4. On the Custom Domain page, configure your custom form URL:

  • Domain name

    Type in the desired domain name for your form. For example, if your domain is, consider using or

  • Customize domain redirect

    Choose what happens when visitors go to your custom domain without adding /form/some_form_id to the end of the URL:

    • Redirect to URL
      Specify a particular URL for redirection.

    • Redirect to Published Form
      Direct visitors to the published form version.

  • Customize error page
    Use your own custom error page instead of the default.


    When your custom domain is set up correctly, a customized error page displays if visitors encounter issues accessing or submitting forms. This page is user-friendly and informative.

  • Add error codes to your URL

    If enabled, error codes are added to the URL (e.g., ?errorcode=404) for HTTP errors like “404 Not Found.”

  • Upload Favicon

    Add a PNG or JPG icon (under 1MB) to show in the browser’s address bar when users access your form via the custom URL. Recommended size: 192x192 pixels.

  1. After confirming your edits, click Save.

    Once saved, you’ll receive a CNAME value. Keep this value as you’ll need it later to adjust DNS details and complete the setup.

Change your DNS settings

To complete your custom domain setup, you need to change your DNS details on your domain registrar’s site. Here’s how you do it:

  1. Log in to your domain registrar’s account and find the section related to DNS settings or domain management.


    Different registrars may use different terms for accessing DNS settings, so it’s best to look for options like “DNS Management,” “DNS Settings,” or “Manage DNS.” If you need specific guidance on setting up CNAME forwarding for your custom domain, we recommend you reach out to the registrar’s support team.

  2. On the settings page, add the CNAME value generated in the previous steps from PlatoForms. For example:

  3. Add the CNAME you received to direct it to PlatoForms.


CNAME changes may take between 24 and 48 hours to take effect.

Once your CNAME record is set up correctly, your published forms will have a unique sharing URL that matches your custom domain name. For instance, it will look like this:

HTTPS/SSL protection

We prioritize the security of your sensitive data, especially when using custom domains. That’s why we ensure your forms are protected with HTTPS/SSL encryption through Let’s Encrypt. As soon as your CNAME record is active, we start the SSL certificate installation process. Within approximately 4 hours, your custom domain will be fully covered with HTTPS protection, keeping your data safe and secure.

API integration

After setting up your custom domain successfully, the form URL returned by our API will use your domain URL.

Use custom domain and PlatoForms URL

Even if your custom domain is functioning correctly, you can still access the form using our original PlatoForms URL.

To do this, replace your custom URL ( with our PlatoForms URL ( Ensure that you remove the /form from your URL as it is unnecessary when using our native domain.

CNAME value format

The CNAME value always follows the same format:


This allows you to setup CNAME before the custom domain is set.
