Mastercard Gateway contains a ***Payment Options Inquiry*** API operation that allows you to obtain information about various payment options that have been configured for your merchant account. You can offer the available options to your payers when they are making a payment for an order.

## Supported integration and payment methods {#supported-integration-and-payment-methods}

|      Integration methods      | Payment methods |

| Hosted Session Direct Payment | All             |

The options returned by the inquiry depend on your merchant profile configuration in the gateway and the content of your request. For example, when you provide the order currency in the request, the response only contains payment options that are available for orders with this currency. For details on the fields to be used in the API request, see ***Payment Options Inquiry***.

## Types of inquiries {#types-of-inquiries}

You can make the following kinds of inquiries or combinations of them:

* List of available [payment methods](https://developer.mastercard.com/mastercard-gateway/documentation/payment-methods/index.md)  

  You can determine, for example, whether your payer is allowed to use a credit card or PayPal for their payment.

* List of supported card types  

  You can determine which card schemes you can allow your payer to use.

* Card-related details  

  You can use the payer's card number prefix to retrieve details about the card scheme, brand, and funding method, to assist you in any [surcharging](https://developer.mastercard.com/mastercard-gateway/documentation/gateway-features/funding-and-fee-information/surcharging/index.md) decisions.

* List of allowed transaction sources  

  You can determine the channels through which you are allowed to gather the payer's authorization for the order.

* Currency-related details  

  You can determine the currencies you can support. In addition, if the payer wants to use a different currency in their order, you can retrieve a [Dynamic Currency Conversion](https://developer.mastercard.com/mastercard-gateway/documentation/gateway-features/funding-and-fee-information/dynamic-currency-conversion/index.md) (DCC) quote to give the payer the exact amount information in the currency they prefer.

* List of valid payment plans for a transaction  

  If you want to give the payer the option of paying in installments, you can retrieve available payment plans. Use the data to show the payer the details of the possible plans they can choose from.
