## CreatePaymentResult

<GenerationInfo sourceFile="packages/core/src/config/payment/payment-method-handler.ts" sourceLine="30" packageName="@vendure/core" />

This object is the return value of the <a href='/reference/typescript-api/payment/payment-method-types#createpaymentfn'>CreatePaymentFn</a>.

```ts title="Signature"
interface CreatePaymentResult {
    amount: number;
    state: Exclude<PaymentState, 'Error'>;
    transactionId?: string;
    errorMessage?: string;
    metadata?: PaymentMetadata;
}
```

<div className="members-wrapper">

### amount

<MemberInfo kind="property" type={`number`}   />

The amount (as an integer - i.e. $10 = `1000`) that this payment is for.
Typically this should equal the Order total, unless multiple payment methods
are being used for the order.
### state

<MemberInfo kind="property" type={`Exclude&#60;<a href='/reference/typescript-api/payment/payment-state#paymentstate'>PaymentState</a>, 'Error'&#62;`}   />

The <a href='/reference/typescript-api/payment/payment-state#paymentstate'>PaymentState</a> of the resulting Payment.

In a single-step payment flow, this should be set to `'Settled'`.
In a two-step flow, this should be set to `'Authorized'`.

If using a <a href='/reference/typescript-api/payment/payment-process#paymentprocess'>PaymentProcess</a>, may be something else
entirely according to your business logic.
### transactionId

<MemberInfo kind="property" type={`string`}   />

The unique payment reference code typically assigned by
the payment provider.
### errorMessage

<MemberInfo kind="property" type={`string`}   />

If the payment is declined or fails for ome other reason, pass the
relevant error message here, and it gets returned with the
ErrorResponse of the `addPaymentToOrder` mutation.
### metadata

<MemberInfo kind="property" type={`PaymentMetadata`}   />

This field can be used to store other relevant data which is often
provided by the payment provider, such as security data related to
the payment method or data used in troubleshooting or debugging.

Any data stored in the optional `public` property will be available
via the Shop API. This is useful for certain checkout flows such as
external gateways, where the payment provider returns a unique
url which must then be passed to the storefront app.
