Integration Flow

Overview of Integration Flow

payment flow

Explanation of payment flow

  1. Merchant calls /v1/checkouts to send cart data to Sezzle.
  2. Sezzle returns URL to redirect consumer to make payment at Sezzle checkout.
  3. Merchant redirects the consumer to Sezzle.
  4. When the consumer completes the Sezzle checkout flow, they are redirected back to merchant’s website.
  5. Alternatvely, on approval, the consumer is redirected from Sezzle checkout to merchant’s website and merchant captures the order by calling /v1/complete.

Authentication

Obtain Authentication Token

To authorize, use the following format:

Request Body

{
    "public_key": "myPublicKey",
    "private_key": "myPrivateKey"
}

Make sure to replace keys with your API keys from your Merchant Dashboard.

Response Body

    "merchant_uuid": "merchant1234567890"
}

POST https://gateway.sezzle.com/v1/authentication

Sezzle Pay uses scoped API keys to allow access to the API. You can find/generate these keys on your merchant dashboard once you have been approved by Sezzle.

Once you have a valid token, it must be used as a Header for subsequent requests to our API, using the format below.

HTTP Request

POST https://gateway.sezzle.com/v1/checkouts

This checkout endpoint creates a checkout in our system, and returns the URL that you should redirect the user to. We suggest you provide as much optional information about the user as you have available, since this will speed up our checkout process and increase conversion.

Sezzle is able to handle the entire checkout process after a Checkout has been provided. However, if your flow requires that the user confirm their checkout on your site after being approved by Sezzle, you may include the merchant_completes parameter with the checkout request. In this flow, Sezzle will not complete the order unless you make a checkout completion request.

Success response

Echos the given Checkout.

Rejection response

{
    "status": 409,
    "id": "checkout_expired",
    "message": "checkout not completed within time limit"
}

POST https://gateway.sezzle.com/v1/checkouts/{order_reference_id}/complete

If you pass true to merchant_completes in our Create Checkout flow, then you must call our Complete Checkout endpoint.

For some checkouts, a merchant may need to have the user return to their site for additional steps before completing the purchase. If this is the case, the order completion endpoint is used to complete the Checkout with Sezzle. From the time the user is redirected back to the Merchant’s site, you must make the request to complete the checkout within 30 minutes, or the checkout will be cancelled by Sezzle. If the checkout has expired, we will return the rejection response on the right, with a Status 409.

There are two non-error responses expected. Either an HTTP 200, which echos all accepted fields given at Checkout creation, or a rejection message.

We expect any response in the 200 range on submitting webhooks.

Order Webhook Object

Parameter Type Description
time string The time (UTC) at which the Webhook was generated.
uuid string A unique identifier for the webhook.
type string The high-level category. For example, order_update

Errors

Sezzle API Errors

Response Error Body

{
    "status": 400,
    "id": "error_id",
    "message": "Descriptive message"
}

Unless otherwise specified in our documentation, Sezzle returns a standard API error object.

We attempt to keep these errors as consistent as possible, and will announce any changes in advance if they are required.

Error Object

Parameter Type Description
Status int Matches the HTTP Status code of the response
ID string A programmatic identifier for the error. These rarely (if at all) change.
Message string A human-friendly string. These may change, and are intended to assist in debugging rather than program logic.

SezzleJS

        sezzleWidgetContainerClass: 'class-to-element-where-sezzle-element-will-be-rendered',
        hidePrice: true,
        altVersionTemplate: 'sezzle is the best %%logo%% %%link%%',

    }

Not all options in the config above are required.

The config must be specified in a property of the document object called document.sezzleConfig. SezzleJS provides various options in order to customize the widget. The explanation for all the options can be found below:

targetXPath (required)

Purpose: Path to the element in your webpage from where the product price would be picked up from.
Type: string, array of strings
Default: empty
Additional Details: Specify one path if only one price element is targeted. Specify multiple paths in an array if multiple price elements are targeted. The path may contain multiple subpaths. All subpaths need to be separated by the ’/’ character. IDs need to be preceeded by a ’#’ character. Classes needed to be preeceeded by a ’.’ character and tag names have to have the indexes specified. The format of a tagname is as follows: tagName-Index (e.g. SPAN-2). The indexes are zero based.

Example: #ProductSection/.product-price/SPAN-1 would target the 2nd SPAN element contained within elements which contain the product-price class which are contained within the element with an ID of ProductSection.

renderToPath (optional)

Purpose: Path to the element in your webpage where the sezzle widget will be rendered to. This is relative to targetXPath.
Type: string, array of strings
Default: ../
Additional Details: Path to the element right above the widget (widget’s previous element sibling). You may want to place widgets in multiple places. So you can pass multiple paths in an array. The price path in the ith index of targetXPath array will rendered at the path given in the ith index of this array(renderToPath). If you do not pass any thing to ith index of this array but there is a path in ith index of targetXPath, then the widget will be rendered right below the parent of the corresponding target element. Like, targetXPath, prepend IDs with ’#’, classes with ’.’ and append tag names with the index (tagName-Index)
../ => go up one parent element
./ => place widget as next element sibling of the target element

forcedShow (optional)

Purpose: Shows the widget in every country if true. Else it shows up only in the United States.
Type: boolean
Options: false, true
Default: false

alignment (optional)

Purpose: Aligns the widget relative to the parent element.
Type: string
Options: left, center, right
Default: center

merchantID (required)

Purpose: ID given by Sezzle to the merchant. This can be found in the upper right corner of the Sezzle merchant dashboard. Only approved merchants get an ID.
Type: string
Default: empty

theme (optional)

Purpose: Dark and light theme for the widget to work with different background colors of websites.
Type: string
Options: dark, light
Default: light

imageUrl (optional)

Purpose: The sezzle logo can be replaced in the widget with an external image of choice.

hideClasses (optional)

Purpose: The classes of elements that should be hidden when sezzle’s logo is showing. This is useful when you want to hide a similar product as Sezzle and is not available in a country where Sezzle is.
Type: array of strings
Default: empty

priceElementClass (optional)

Purpose: Class to the price element. This option is used instead of targetXPath to make the integration simple. You can pass this as a class of your choice else it defaults to sezzle-price-element. If you have just one element in your page with this class added to it (which should be the price element), the system would pick up price using this.
Type: string
Default: sezzle-price-element

sezzleWidgetContainerClass (optional)

Purpose: Class to the element in which you want to render the sezzle widget. This option is used instead of renderToPath to render the sezzle widget in a simpler way. This is supposed to be used with priceElementClass. You can pass this as a class of your choice else it defaults to sezzle-widget-container. You should have one element in your page which has this as a class and then the system would render the widget below that element.
Type: string
Default: sezzle-widget-container

hidePrice (optional)

Purpose: Some websites have problems rendering the sezzle widget on variant change. This can be used to not have the price rendered in the sezzle widget and only the text and logo would be shown.
Type: boolean
Default: false

altVersionTemplate (optional)

Purpose: This is used to change the text of the widget and also change the arrangement of text, logo and the know more url within the widget. As an example, or 4 automatic, interest free payments with %%price%% %%logo%% %%link%% will render the default widget.
Type: string
Default: empty
Additional Details: Currently available templates: %%price%%, %%logo%%, %%link%%, %%info%%, %%question-mark%%

fontSize (optional)

Purpose: This sets the font size of the widget text in pixels (Enter numbers only. Do not enter px!)
Type: number
Default: inherited from the website’s stylesheet.

fontWeight (optional)

Purpose: This is used to set the boldness of the text. 100 is the lightest, 900 is the boldest.

alignmentSwitchMinWidth (optional)

Purpose: Minimum screen width in pixels below which the alignment switches to alignmentSwitchType.

Type: number
Default: 0

marginBottom (optional)

Purpose: Amount of space below the widget in pixels.
Type: number
Default: 0

splitPriceElementsOn (optional)

Purpose: Character/string to split the price elements on (for elements with price ranges)
Type: string
Default: empty
Additional Details: Certain websites, especially wooCommerce websites have price ranges as their price element (e.g. $650 - $1000). Setting this field to the character/string which separates the prices(e.g. in the case above, it is ’-’) enables the widgets to parse the price elements separately. For instance, setting this field to ’-’ would cause the widget to render the widget price above to $162.50 - $250.00.

Uploading the Widgets

After building up the config, it is time to upload the widgets to your web pages! sezzle.js needs to be called in the HTML of your webpage in order for the widgets to be rendered. Place the config and the sezzle.js script at the bottom of your HTML page and you should be all set!

Placing the code snippet below in your HTML loads sezzle.js into your webpage.

<script src="https://widget.sezzle.com/v1/javascript/price-widget/initial"></script>

The script must be called only after the config is specified (document.sezzleConfig is defined). Here is a complete example:

<script>
    document.sezzleConfig = 
    {
        targetXPath: '<path-to-price-element>',
        renderToPath: '<relative-path-to-element-to-which-to-render-this-widget>',
        forcedShow: false,
        alignment: 'left',
        merchantID: '<your-sezzle-merchant-id-here>',
        theme: 'light',
        widthType: 'thin',
        widgetType: 'product-page',
        minPrice: 0,
        maxPrice: 100000,
        imageUrl: 'example.com/example.png',
        hideClasses: ['class-to-hide'],
        priceElementClass: 'class-to-element-which-contains-price',
        sezzleWidgetContainerClass: 'class-to-element-where-sezzle-element-will-be-rendered',
        hidePrice: true,
        altVersionTemplate: 'sezzle is the best %%logo%% %%link%%',
        fontWeight: 200,
        alignmentSwitchMinWidth: 800,
        alignmentSwitchType: 'right',
        maxWidth: 200,
        marginTop: -20,
        marginBottom: -20,
        fontSize: 13
    }
