# Payment Methods. How Payment Method Affect Your post-purchase upsells

In some cases, post-purchase offers created using the Adoric Post Purchase app may not be displayed. This is due to certain limitations in **Shopify's Post-purchase Extensions API**. Please refer to [Shopify's official documentation](https://shopify.dev/docs/apps/checkout/product-offers/post-purchase#limitations-and-considerations) for more details on these limitations.


| The use of unsupported payment methods is one of the main reasons why post-purchase offers might not show up.

Here, we will walk you through which payment methods are supported and which might prevent your post-purchase campaigns from being displayed.

## Supported Payment Methods

To ensure that your post-purchase offers appear correctly, it is important to use payment methods that are fully compatible with Shopify and the Adoric Post Purchase app. Below is a list of supported payment methods:

* **Shopify Payments (for Credit Cards)**
This is the most reliable payment method to ensure your post-purchase offers display correctly.
* **Shop Pay**
Shop Pay is fully compatible with post-purchase offers created using Adoric Post Purchase.
* **PayPal Pro, PayPal PayFlow** (when used with a credit card)
These PayPal services work well with post-purchase offers, provided a credit card is used.
* **PayPal Express** (with [Automatic Payments enabled](https://docs.google.com/document/d/1x5aDxNdd2kOA5P8hU522rCJF86nelpkhr5YvRQ4OOWc/edit#heading=h.souu93sv6lsc))
Known as Reference Transactions by PayPal, PayPal Express supports post-purchase offers when Automatic Payments are activated. Learn more about PayPal Automatic Payments.
* **Braintree **(without CVV verification enabled)
Braintree is supported as long as CVV verification is turned off.
* **Authorize.net**
This payment method also supports post-purchase offers without issues.
* **Stripe**
|| NOTE: The newer versions of Stripe are no longer supported by Shopify's Post-purchase Extensions API. However, older versions remain compatible.

##  Other Direct Credit Card Payment Processors

Any credit card processor that is fully embedded within Shopify's checkout (i.e., it does not require redirecting customers to an external page) is supported.
* **Unsupported Payment Methods**
The following payment methods are currently not supported for post-purchase offers in Adoric Post Purchase:
* **Installment Services**
Payment services that allow customers to pay in installments, such as Affirm, Sezzle, AfterPay, Klarna, or Shop Pay Installments, are not supported.
* **Unsupported Payment Wallets**
Wallet services like Apple Pay, Amazon Pay, and Google Pay are not compatible with post-purchase offers.
* **Bank Transfer Payment Methods**
Payment methods like iDeal and Airwallex that involve bank transfers will not display post-purchase offers.
* **Gift Cards**
Orders paid entirely with a gift card will not display post-purchase offers. However, if an order is partially paid with a gift card (e.g., $20 gift card on a $35 order), and the remaining balance is covered with a supported payment method, post-purchase offers will be shown.
* **Cash on Delivery**
Due to Shopify's restrictions on post-purchase offers, Cash on Delivery (COD) orders will not display post-purchase upsells.

Choosing the correct payment method is essential for ensuring that your Adoric Post Purchase offers are displayed to your customers. We recommend using **Shopify Payments** or other fully supported methods to avoid issues related to unsupported payment methods and the limitations of Shopify's Post-purchase Extensions API. If you're unsure which payment methods to use, refer to the lists above for guidance.
