Onboarding to VIS
If you are a Shopify for Visa merchant, to prepare your account there are a few things you'll need to do:
1. Add On-Site Messaging
Installation and Configuration
1. Go to the On-Site Messaging app's URL. Click Install (if you are already logged into your Shopify account), or click Log in to Install, then select your Shopify account.

2. On the next page, click Install, which will take you to a configuration page.
3. Enable the app and Visa Installments using the switches at the top of the page.

4. Find your Splitit Payment Terminal API Key, which you can get from your Splitit Hub. In your Merchant Hub, go to Merchants Management on the left-hand side. Click on your merchant name, then in the new window, go to Terminals on the left-hand side, then copy the Terminal Id you'd like to use (this is the Payment Terminal API Key). Enter your key in the field Payment Terminal API Key. (Make sure to Save at the bottom if you aren't changing any other configurations.)

5. In the next box, enter the default number of payments by which you'd like to divide a product's price.

6. In the box after that, select the theme for which you'd like to display On-Site Messaging (this allows you to enable the plugin for certain themes only).

7. Finally, define which products will show Splitit messaging on your website.

-
Show Splitit on All Products is recommended and the default
-
Show Splitit Customer Journey per product's minimum amount lets you set a minimum product price for On-Site Messaging. If you select this, enter a minimum product amount.

Page Settings
You can configure On-Site Messaging separately for your home page, catalog page, product page, and cart page, and thus each of these pages has a section where you can choose from strips, banners, logos and one liners. Refer below for information about customizing the individual elements. (You can see what each does in your Shopify admin by changing it then clicking Preview.)
Strips
Banners
Logos
One Liners
Configuring CSS Selectors
As you learned in Page Settings above, in some cases the app requires that you use CSS selectors to specify proper locations for your On-Site Messages. To place the On-Site Message in the proper location, you must fill in the corresponding field. Below are some tips for finding these selectors.
How to Find and Use Selectors in the App
Custom CSS
The last configurable section block is On-Site Messaging CSS. It allows you to add custom CSS code to modify the styles of the On-Site Messages. Make sure to click Save once you are finished on this page.
Testing
Use unpublished themes to test your configuration. You can create a duplicate of the theme you're using, then enable the app for this theme only.

Once that is done, go to Sales Channels > Online Store > Themes, find the theme and preview it.

2. Modify your thank you page
- In your store's Shopify admin panel, go to the Settings section.

- Select the checkout section.

- Scroll down to the order status page section.

- In the Additional scripts field, add the code below:
Thank you page script
- Save the form.

Attention!
-
Before checking this functionality on the Order Confirmation page, clear the cache.
-
After that, you will be able to see the following block with information in the thank you page on your store:
