In-Page Configuration Token

Note

This property was introduced in Connector Script 3.

See the predecessor JWT Dynamic Paid Content API for integrations using Connector Script 2.

The In-Page Configuration Token allows you to publish new paid content without having to configure anything in Connector Admin Interface.

This is the most prominent change with Connector Script 3: You can now define Purchase Options of all Sales Models via the In-Page Configuration Token (Single Purchases, Time Passes and Subscriptions). It also allows for more granular control over which Purchase Options from Connector Admin Interface should be presented to the user.

Create a signed JSON web token (JWT) containing the required Purchase Options and sign it with your secret API Key. Then pass it as the In-Page Configuration Property laterpay:connector:config_token:

Example for Connector Script Classic:

<meta property="laterpay:connector:config_token" content="[...]">

Example for Connector Script For Video Players:

{
  laterpayConnector: {
    configToken: '[...]'
  }
}

Note, that in the examples above, [...] is used as a placeholder for the actual token. See details on how to create the In-Page Configuration Token in the following sections.

Note

Your secret API Key can be retrieved from the “Developer” section in Merchant Backend. The URL that you use to access Merchant Backend depends on the region and environment of your integration. You can find the appropriate URL in section URLs of Merchant Backend.

JWT Object Properties

This is a JSON Web Token per RFC 7519, encoding In-Page Purchase Options and other options.

The JWT consists of three parts:

  1. The header, defining the algorithm and type
  2. The payload, defining the In-Page Purchase Options and other options
  3. The signature
Header:

The header must use the HS256 algorithm and the JWT type:

{
    "alg": "HS256",
    "typ": "JWT"
}
Payload:

The payload has one required key purchase_options. The keys ignore_database_single_purchases, ignore_database_subscriptions, ignore_database_timepasses, and template are optional.

purchase_options:
 

Required

An array of Purchase Options. Each element is an object with an article_id, a price, a sales_model and a title. For Subscriptions and Time Passes, a description and an expiry are also required.

article_id:

Required

Article IDs give more flexibility by allowing to use them on arbitrary sides or content, regardless of the URL.

An article_id has to match the RegEx ^[a-zA-Z0-9_-]{1,128}$.

In other words, it’s a string consisting of letters, digits, hyphens and underscores no longer than 128 characters that is unique for the article being offered.

price:

Required

An object stating the amount, currency, and Payment Model. For a 1.23 EUR “Pay Later” pricing, using this:

"price": {
    "amount": 123,
    "currency": "EUR",
    "payment_model": "pay_later"
}

A 4.99 EUR “Pay Now” pricing looks like this:

"price": {
    "amount": 499,
    "currency": "EUR",
    "payment_model": "pay_now"
}
sales_model:

Required

Either “single_purchase”, “subscription”, or “timepass”.

title:

Required

A human-readable string with at most 256 characters.

description:

Required when ``sales_model`` is a Subscription or Time Pass

A human-readable string that is shown below the title. While the title for a Time Pass might be “Week pass”, the description could be “7 day access to all our premium content”.

expiry:

Required when ``sales_model`` is ``subscription`` or ``timepass``

Defines the duration/expiration of the Subscription or Time Pass.

The unit can be one of "h", "d", "w", or "m" for hour, day, week or month.

The value can be any integer from 1 to 24 (including):

"expiry": {
    "unit": "w",
    "value": 2
}
ignore_database_single_purchases:
 

Optional

Boolean value that defines if Single Purchases that were defined through Connector Admin Interface should be ignored and thus should not be presented to the user.

ignore_database_subscriptions:
 

Optional

Boolean value that defines if Subscriptions that were defined through Connector Admin Interface should be ignored and thus should not be presented to the user.

ignore_database_timepasses:
 

Optional

Boolean value that defines if Time Passes that were defined through Connector Admin Interface should be ignored and thus should not be presented to the user.

template:

Optional

Most times templates will be assigned to Purchase Options through Connector Admin Interface. If a different template should be used for this page, pass the UUID of the template here.

Signature:

The signature is the HMAC-SHA-256 over the base64 URL encoded header, concatenated with a ., concatenated with the base64 URL encoded payload. The key or secret for the signature function is the merchant’s secret.

Example

Given this payload:

{
    "purchase_options": [
        {
            "article_id": "article_12345",
            "price": {
                "amount": 42,
                "currency": "EUR",
                "payment_model": "pay_later"
            },
            "sales_model": "single_purchase",
            "title": "Team A wins over Team B"
        },
        {
            "article_id": "category_sports",
            "price": {
                "amount": 899,
                "currency": "EUR",
                "payment_model": "pay_now"
            },
            "sales_model": "subscription",
            "title": "Monthly Sports Subscription",
            "description": "Monthly subscription to all our sports news",
            "expiry": {
                "unit": "m",
                "value": 1
            }
        },
        {
            "article_id": "category_sports",
            "price": {
                "amount": 234,
                "currency": "EUR",
                "payment_model": "pay_now"
            },
            "sales_model": "timepass",
            "title": "7 Days of Sport",
            "description": "Access to all our sports news for 7 days",
            "expiry": {
                "unit": "d",
                "value": 7
            }
        }
    ],
    "ignore_database_single_purchases": true,
    "template": "78c10144-1ee9-4547-a6b4-d16f742102cd"
}

and a merchant secret 2e910ba0f326421a8fa7dfe1621755e2 will result in a JWT much like this (line breaks for readability):

This JWT will result in Connector Script showing no database defined Single Purchases for this page, but all database defined Subscriptions and Time Passes for this page. Additionally, a “Pay Later” Single Purchase for 42 Euro cents, a monthly Subscription for 8.99 EUR and a one-week Time Pass for 2.34 EUR will be shown. Lastly, the template Connector Service will return the template with the ID 78c10144-1ee9-4547-a6b4-d16f742102cd.
