Embedding your Tulo Paywall

Version-independent information can be found below. For documentation on the version-specific functionality see available versions above.

Including the Paywall Javascript

To utilize the Payway Paywall Javascript you must include the script. See available versions for the appropriate address of the desired version and environment.

Define the HTML container for your Paywall

To embed your Tulo Paywall, you will first need to define an HTML container where the paywall should live. This container can be anywhere on your site, though we recommend you give it plenty of space.

<div id="paywall-container"></div>

Initializing the Paywall Javascript

With the HTML container in place, you must initialize the Javascript. This will take care of embedding your paywall into the container:

<script type="text/javascript">
    new Paywall().Init({
        url: "https://payway-paywall-stage.adeprimo.se/api/paywall",
        jwtToken: "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c"
        debug: false
        ....
        ....
        ....
    });
</script>
Paywall.Init example

When initializing the Tulo Paywall script, an url and jwtToken must be provided. For information on all available attributes see the version-specific documentation.

Tulo Paywall URL

Choose the correct url, depending on what environment you are working in.

Environment URL
Production https://paywall.worldoftulo.com/api/paywall
Staging https://payway-paywall-stage.adeprimo.se/api/paywall

Text resources

There are several overridable text resources. Here you'll find which they are and when and where they occur. These resources can overridden using the resources property.

Property Type Default value Description
loadingText string Loading... Text that is shown under the loading icon when the Tulo Paywall UI is rendering
errorHeader string An error has occurred The header shown when an error occurs
errorDescription string Something unexpected happened. Please try again later, and if the problem persists, contact support. The description shown when an error occurs

Error handling

If an error within the Tulo Paywall occurs, an onError function will be triggered. By default, this means that an error will be shown to the end-user, and you will receive debug information (granted the debug flag is set to true) in the browser console.

If you would like to override this behavior, you can simply define an onError function when initializing the paywall. Furthermore, the function should accept one argument, in the form of the exception that was thrown. The exception that is thrown will always contain the following information:

Property Type Description
name string Will always be set to "PaywallError"
code string The error code that was thrown
field string The field relating to the error that was thrown
pwCorrelationId string The correlation ID of the error. If you contact our support regarding a Tulo Paywall error, this ID should always be included in the support request.
toString function Returns a stringified version of the error.

The default error that is shown to the end user will always look like the following, though the text resources are customizable via the resources property.
