## Payment Methods

Before deciding the payment methods or payment instruments that you want to configure on the Checkout, refer to the [payment methods](/payments/payment-methods) supported by Razorpay.

## Payment Instruments

A payment instrument is a combination of the payment method and its associated properties. For example, a payment instrument can be an **AXIS Debit card**, where **card** is the payment method and the issuer (AXIS bank) is the associated **instrument**.

An instrument is a JSON object with a key named `method`. Each method and its associated properties are described in the sections below:

### Card

Payment instruments for the `method: card` are listed below:

## Name | Type | Description | Values | Examples

## issuers | array | List of issuers that are allowed | [Any bank code](/payments/payment-gateway/web-integration/standard/configure-payment-methods/supported-methods#supported-banks) | `issuers: ["HDFC", "ICIC"]`

## networks | array | List networks that are allowed | [Any card network](/payments/payment-gateway/web-integration/standard/configure-payment-methods/supported-methods#supported-card-networks) | `networks: ["Visa", "MasterCard"]`

types | array | List of card types that are allowed | [Any card type](/payments/payment-gateway/web-integration/standard/configure-payment-methods/supported-methods#supported-cards) | `types: ["credit", "debit"]`

      }
    ]
},
...
//rest of the code
```

## Name | Type | Description | Values | Examples

## flows | string | Flows to show | [Any supported UPI flow](/payments/payment-gateway/web-integration/standard/configure-payment-methods/supported-methods#supported-upi-flows) | `flows: [ "qr"]`

apps | string | Apps to show, for intent | [Any supported UPI apps](/payments/payment-gateway/web-integration/standard/configure-payment-methods/supported-methods#supported-upi-apps) | `apps: ["google_pay", "phonepe"]`

### EMI

Payment instruments for the  `method: emi` are listed below:

## Name | Type | Description | Values | Examples

## issuers | array\`\`  | Providers to be allowed | [Any EMI issuers](/payments/payment-gateway/web-integration/standard/configure-payment-methods/supported-methods#supported-emi-providers) | `issuers: ["HDFC, ICIC"]`

## types | array\`\`  | Providers to be allowed | Any [credit](/payments/payment-gateway/web-integration/standard/configure-payment-methods/supported-methods#supported-credit-card-emi-providers) and [debit](/payments/payment-gateway/web-integration/standard/configure-payment-methods/supported-methods#supported-debit-card-emi-providers) card EMI type | `types: ["debit, credit"]`

iins | array\`\` | Providers to be allowed | [Any EMI IIN](/payments/payment-gateway/web-integration/standard/configure-payment-methods/supported-methods#supported-emi-providers) | `iins: ["438600"]`

### Cardless EMI

Payment instruments for the  `method: cardless_emi` are listed below:

## Name | Type | Description | Values | Examples

providers | string | Providers to be allowed | [Any Cardless EMI provider](/payments/payment-gateway/web-integration/standard/configure-payment-methods/supported-methods#supported-cardless-emi-providers) | `providers: ["zestmoney"]`

### Pay Later

For the  method: `paylater`, the payment instruments are listed below:

## Name | Type | Description | Values | Examples

providers | string | Providers to be allowed | [Any paylater provider](/payments/payment-gateway/web-integration/standard/configure-payment-methods/supported-methods#supported-paylater-providers) | `providers: ["hdfc"]`

### Apps

For the method `app`, the payment instrument is listed below:

## Name | Type | Description | Values | Examples

providers | string | Providers to be allowed | [Any app provider](/payments/payment-gateway/web-integration/standard/configure-payment-methods/supported-methods#supported-apps) | `providers: ["cred"]`

```js: JavaScript theme={null}
// beginning of the code
....
{
  "custom": {
    "name": "Pay with Apps",
    "instruments": [
      {
        "method": "app",
        "providers": [
          "cred"
        ]
      }
    ]
  }
}
...
//rest of the code
```

## Blocks

A block is a collection of one or more payment instruments. Each block has a `name` and `code` associated as shown below:

```js: JavaScript theme={null}
// Block creation
let myPayments = {
  name: "My Custom Block",
  instruments: ["gpay"]
};
// Usage in config
let config = {
  display: {
    blocks: {
      highlighted: myPayments
    }
  }
};
```

Here, `highlighted` is the code associated with `myPayments`. Multiple blocks can be added to the config at the same time.

## Sequence

You can specify the `sequence`, that is the order, in which the payment methods should be displayed on the Checkout.

A sequence is an `array` of strings, where each string is the name of the payment method or a `block`.

In a sequence, you can include any block using the `block.${code}` format. The block with code **highlighted** should be represented as `block.highlighted` as shown below:

```js: JavaScript theme={null}
let sequence = ["block.highlighted", "upi", "netbanking"];
```

The above sequence will place the code `highlighted` first followed by the payment methods `upi` and `netbanking` in that particular order.

<Info>
  **Handy Tips**
</Info>

Every block defined has to be present in the sequence. If you do not wish to reorder the methods and want to place your block, the sequence should contain `block.highlighted` with just one item in it.

## Preferences

Using the `preferences` object, you can enhance the configuration of the Checkout. By setting this value, you can decide whether the default list of payment methods should be displayed or not.

Possible values are:

`true`
: Checkout will display the sequence of the payment methods configured by you alongside with the default order of payment methods available in the Checkout.

`false`
: Checkout will only show the sequence of the payment methods configured by you.

## Hide Payment Instruments

You can also hide or remove certain instruments from the Checkout.

This is an `array` containing the `method` key used to hide either the payment method and/or the payment instrument associated with that payment method. For example, you can hide the methods, `card` and `HDFC netbanking` on the Checkout.

```js: JavaScript theme={null}
let cardInstrument = {
  method: "card"
};

let instrumentOfSomeBank = {
  method: "netbanking",
  banks: ["HDFC"]
};

let hiddenInstruments = [cardInstrument, instrumentOfSomeBank];
```

This is an `array` containing the `method` key used to hide either the payment method and/or the payment instrument associated with that payment method. For example, you can hide the methods, `card` and `Axis netbanking` on the Checkout.

```js: JavaScript theme={null}
let cardInstrument = {
  method: "card"
};

let instrumentOfSomeBank = {
  method: "netbanking",
  banks: ["UTIB"]
};

let hiddenInstruments = [cardInstrument, instrumentOfSomeBank];
```

<Info>
  **Handy Tips**
</Info>

Hiding any instrument using `hide` does not affect the similar instrument defined in `blocks`. So, if you want to hide `UTIB` bank from `netbanking` and have defined the same instrument in one of your blocks, Axis bank will still be displayed in that block.
