### Types of Payments

The Payment transaction type is a general-purpose tool that can represent several different types of abstract actions. You can identify the transaction type based on the transaction's fields, as described in the table below:

| Payment type                 | `Amount`                        | `SendMax`                       | `Paths`          | `Address` = `Destination`? | Description                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           |
| ---------------------------- | ------------------------------- | ------------------------------- | ---------------- | -------------------------- |   |
| Direct XAH-to-XAH Payment    | String (XAH)                    | Omitted                         | Omitted          | No                         | Transfers XAH directly from one account to another. Always delivers the exact amount. No fee applies other than the basic transaction cost.                                                                                                                                                                                                                                                                                                                                                                                           |
| Creating or redeeming tokens | Object                          | Object (optional)               | Optional         | No                         | Increases or decreases the amount of a non-XAH currency or asset tracked in Xahau. Transfer fees and freezes do not apply when sending and redeeming directly.                                                                                                                                                                                                                                                                                                                                                                        |
| Cross-currency Payment       | Object (non-XAH) / String (XAH) | Object (non-XAH) / String (XAH) | Usually required | No                         | Send tokens from one holder to another. The `Amount` or `SendMax` can be XAH or tokens, but they cannot both be XAH. These payments ripple through the issuer and can take longer paths through several intermediaries if the transaction specifies a path set. Transfer fees set by the issuer(s) apply to this type of transaction. These transactions consume offers in the decentralized exchange to connect between different currencies, or possibly even between currencies with the same currency code and different issuers. |
| Partial payment              | Object (non-XAH) / String (XAH) | Object (non-XAH) / String (XAH) | Usually required | No                         | Sends _up to_ a specific amount of any currency. Uses the `tfPartialPayment` flag. May include a `DeliverMin` amount specifying the minimum that the transaction must deliver to be successful; if the transaction does not specify `DeliverMin`, it can succeed by delivering _any positive amount_.                                                                                                                                                                                                                                 |
| Currency conversion          | Object (non-XAH) / String (XAH) | Object (non-XAH) / String (XAH) | Required         | Yes                        | Consumes offers in the decentralized exchange to convert one currency to another, possibly taking [arbitrage](https://en.wikipedia.org/wiki/Arbitrage) opportunities. The `Amount` and `SendMax` cannot both be XAH. Also called a _circular payment_ because it delivers money to the sender. The Data API tracks this type of transaction as an "exchange" and not a "payment".                                                                                                                                                     |

### Special issuer Values for SendMax and Amount

Most of the time, the `issuer` field of a non-XAH \[Currency Amount]\[] indicates the issuer of a token. However, when describing payments, there are special rules for the `issuer` field in the `Amount` and `SendMax` fields of a payment.

* There is only ever one balance between two addresses for the same currency code. This means that, sometimes, the `issuer` field of an amount actually refers to a counterparty, instead of the address that issued the token.
* When the `issuer` field of the destination `Amount` field matches the `Destination` address, it is treated as a special case meaning "any issuer that the destination accepts." This includes all addresses to which the destination has trust lines with a positive limit, as well as tokens with the same currency code issued by the destination.
* When the `issuer` field of the `SendMax` field matches the source account's address, it is treated as a special case meaning "any issuer that the source can use." This includes creating new tokens on trust lines that other accounts have extended to the source account, and sending tokens the source account holds from other issuers.

### Creating Accounts

The Payment transaction type can create new accounts in Xahau by sending enough XAH to an unfunded address. Other transactions to unfunded addresses always fail.

For more information, see Accounts.

### Paths

If present, the `Paths` field must contain a _path set_ - an array of path arrays. Each individual path represents one way value can flow from the sender to receiver through various intermediary accounts and order books. A single transaction can potentially use multiple paths, for example if the transaction exchanges currency using several different order books to achieve the best rate.

You must omit the `Paths` field for direct payments, including:

* An XAH-to-XAH transfer.
* A direct transfer on a trust line that connects the sender and receiver.

If the `Paths` field is provided, the server decides at transaction processing time which paths to use, from the provided set plus a _default path_ (the most direct way possible to connect the specified accounts). This decision is deterministic and attempts to minimize costs, but it is not guaranteed to be perfect.

The `Paths` field must not be an empty array, nor an array whose members are all empty arrays.

For more information, see Paths.

### Payment Flags

Transactions of the Payment type support additional values in the `Flags` field, as follows:

| Flag Name          | Hex Value    | Decimal Value | Description                                                                                                                                                                          |
| ------------------ | ------------ | ------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `tfNoDirectRipple` | `0x00010000` | 65536         | Do not use the default path; only use paths included in the `Paths` field. This is intended to force the transaction to take arbitrage opportunities. Most clients do not need this. |
| `tfPartialPayment` | `0x00020000` | 131072        | If the specified `Amount` cannot be sent without spending more than `SendMax`, reduce the received amount instead of failing outright. See Partial Payments for more details.        |
| `tfLimitQuality`   | `0x00040000` | 262144        | Only take paths where all the conversions have an input:output ratio that is equal or better than the ratio of `Amount`:`SendMax`. See Limit Quality for details.                    |

### Partial Payments

A partial payment allows a payment to succeed by reducing the amount received. Partial payments are useful for returning payments without incurring additional costs to oneself. However, partial payments can also be used to exploit integrations that naively assume the `Amount` field of a successful transaction always describes the exact amount delivered.

A partial payment is any \[Payment transaction]\[] with the `tfPartialPayment` flag enabled. A partial payment can be successful if it delivers any positive amount greater than or equal to its `DeliverMin` field (or any positive amount at all if `DeliverMin` is not specified) without sending more than the `SendMax` value.

The `delivered_amount` field of a payment's metadata indicates the amount of currency actually received by the destination account.

For more information, see the full article on Partial Payments.

### Limit Quality

Xahau defines the "quality" of a currency exchange as the ratio of the numeric amount in to the numeric amount out. For example, if you spend $2 USD to receive £1 GBP, then the "quality" of that exchange is `0.5`.

The `tfLimitQuality` flag allows you to set a minimum quality of conversions that you are willing to take. This limit quality is defined as the destination `Amount` divided by the `SendMax` amount (the numeric amounts only, regardless of currency). When set, the payment processing engine avoids using any paths whose quality (conversion rate) is worse (numerically lower) than the limit quality.

By itself, the `tfLimitQuality` flag reduces the number of situations in which a transaction can succeed. Specifically, it rejects payments where some part of the payment uses an unfavorable conversion, even if the overall _average_ quality of conversions in the payment is equal or better than the limit quality. If a payment is rejected in this way, the transaction result is `tecPATH_DRY`.

Consider the following example. If I am trying to send you 100 Chinese Yuan (`Amount` = 100 CNY) for 20 United States dollars (`SendMax` = 20 USD) or less, then the limit quality is `5`. Imagine one trader is offering ¥95 for $15 (a ratio of about `6.3` CNY per USD), but the next best offer in the market is ¥5 for $2 (a ratio of `2.5` CNY per USD). If I were to take both offers to send you 100 CNY, then it would cost me 17 USD, for an average quality of about `5.9`.

Without the `tfLimitQuality` flag set, this transaction would succeed, because the $17 it costs me is within my specified `SendMax`. However, with the `tfLimitQuality` flag enabled, the transaction would fail instead, because the path to take the second offer has a quality of `2.5`, which is worse than the limit quality of `5`.

The `tfLimitQuality` flag is most useful when combined with partial payments. When both `tfPartialPayment` and `tfLimitQuality` are set on a transaction, then the transaction delivers as much of the destination `Amount` as it can, without using any conversions that are worse than the limit quality.

In the above example with a ¥95/$15 offer and a ¥5/$2 offer, the situation is different if my transaction has both `tfPartialPayment` and `tfLimitQuality` enabled. If we keep my `SendMax` of 20 USD and a destination `Amount` of 100 CNY, then the limit quality is still `5`. However, because I am doing a partial payment, the transaction sends as much as it can instead of failing if the full destination amount cannot be sent. This means that my transaction consumes the ¥95/$15 offer, whose quality is about `6.3`, but it rejects the ¥5/$2 offer because that offer's quality of `2.5` is worse than the quality limit of `5`. In the end, my transaction only delivers ¥95 instead of the full ¥100, but it avoids wasting money on poor exchange rates.
