# Create a Quoted Conversion between user Wallets

POST https://api.sandbox.mangopay.com/v2.01/{ClientId}/conversions/quoted-conversion
Content-Type: application/json

This call triggers a conversion at the rate defined in its quote. The debited funds (sell currency), credited funds (buy currency), and amounts are defined in the quote.

Each quoted conversion requires a dedicated [Quote](/api-reference/quotes/quote-object) object, linked in the `QuoteId`.

Reference: https://docs.mangopay.com/api-reference/conversions/create-quoted-conversion-user-wallets

## Authentication

- `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer <token>`, where token is your auth token. If your platform is using a [proxy](/guides/sca/proxy-management) to take SCA-triggering action on behalf of users, you also need to integrate [mTLS authentication](/guides/sca/platform) and use the `api-mtls` base URL.

## Servers

- `https://api.sandbox.mangopay.com` (Sandbox, default)
- `https://api.mangopay.com` (Production)
- `https://api-mtls.sandbox.mangopay.com` (mTLS Sandbox)
- `https://api-mtls.mangopay.com` (mTLS Production)

## Request

### Path parameters

- `ClientId` (string, required) — Platform's API account identifier, associated with the API key.

### Body (application/json)

This endpoint expects a CreateAQuotedConversionBetweenUserWalletsRequest.

- `QuoteId` (string, required) — The unique identifier of the active quote which guaranteed the rate for the conversion.
- `AuthorId` (string, required) — The unique identifier of the user at the source of the transaction. In a conversion, both the debited and credited wallets are owned by the author.
- `DebitedWalletId` (string, required) — The unique identifier of the debited wallet (in the sell currency).
- `CreditedWalletId` (string, required) — The unique identifier of the credited wallet (in the buy currency).
- `Tag` (string, optional) — Max. length: 255 characters Custom data that you can add to this object, such as unique identifiers in your system. To store multiple values, you can serialize them into a single string, for example a JSON object: `"{\"id_1\":AB123,\"id_2\":DE456}"`.

- `Type` (string, optional) — The category of the error.
- `Id` (string, optional) — Unique identifier of the error instance, useful when contacting Mangopay for support.

## Types

### CreateAQuotedConversionBetweenUserWalletsResponseDebitedFunds

Information about the debited funds.

- `Currency` (string, optional) — **Allowed values:** The three-letter ISO 4217 code (EUR, GBP, etc.) of a supported currency (depends on feature, contract, and activation settings). The currency of the amount.
- `Amount` (integer, optional) — An amount of money in the smallest sub-division of the currency (e.g., EUR 12.60 would be represented as `1260` whereas JPY 12 would be represented as just `12`). During a conversion, (`DebitedFunds.Amount` - `Fees`) * `MarketRate` = `CreditedFunds.Amount`.

### CreateAQuotedConversionBetweenUserWalletsResponseCreditedFunds

Information about the credited funds.

- `Currency` (string, optional) — **Allowed values:** The three-letter ISO 4217 code (EUR, GBP, etc.) of a supported currency (depends on feature, contract, and activation settings). The currency of the amount.
- `Amount` (integer, optional) — An amount of money in the smallest sub-division of the currency (e.g., EUR 12.60 would be represented as `1260` whereas JPY 12 would be represented as just `12`). During a conversion, `CreditedFunds.Amount` = (`DebitedFunds.Amount` - `Fees`) * `MarketRate`.

### Fees_ConversionResponse

Information about the fees taken by the platform for this transaction (and hence transferred to the Fees Wallet). **Note:** The fees currency must match the debited funds currency.

- `Currency` (string, optional) — **Allowed values:** The three-letter ISO 4217 code (EUR, GBP, etc.) of a supported currency (depends on feature, contract, and activation settings). The currency of the amount.
- `Amount` (integer, optional) — The amount of the currency in its minor unit. For example, EUR 12.60 would be represented as `1260` whereas JPY 12 would be represented as just `12`.

### RequestedFees_Conversion

Information about the `Fees` sent in the request.

- `Type` (string, optional) — **Allowed values:** `PERCENTAGE`, `FIXED` **Default value:** `FIXED` The type of the `Value`.
- `Value` (integer, optional) — The value to be used for the `Type`: - `PERCENTAGE` – In quantities of 0.1% (e.g. `150` equals 1.5%), the percentage of `DebitedFunds.Amount` deducted as fees. - `FIXED` – The amount deducted from `DebitedFunds.Amount` as fees, as an amount of money in the smallest sub-division of the currency (e.g., EUR 12.60 would be represented as `1260` whereas JPY 12 would be represented as just `12`).
- `Currency` (string, optional) — **Allowed values:** The three-letter ISO 4217 code (EUR, GBP, etc.) of a supported currency (depends on feature, contract, and activation settings). The currency of the fees, which must match the debited currency.

### ConversionRateResponse

Information about the `MarketRate` used to convert funds and other indicative rates.

- `ClientRate` (double, optional) — Max. 7 decimal places The indicative rate including Mangopay's markup, used during the billing cycle: `ClientRate` = `MarketRate` * (1 - `MarginsResponse.Mangopay`). The `MarginsResponse.Mangopay.Amount` gives the amount of debited currency that will be billed by Mangopay to your platform for the transaction. The `ClientRate` fluctuates in line with the `MarketRate`.
- `MarketRate` (double, optional) — Max. 7 decimal places The rate used to convert funds during the conversion: (`DebitedFunds.Amount` - `Fees`) * `MarketRate` = `CreditedFunds.Amount`. The market rate fluctuates in line with FX market dynamics and is common to all platforms for the currency pair.
- `FinalRate` (double, optional) — Max. 7 decimal places The indicative rate including the `UserMargin`, if your platform defined it in the request or the quote: `FinalRate` = `ClientRate` * (1 - `MarginsResponse.User`). The `MarginsResponse.User.Amount` gives the amount of debited currency that your platform could bill to the user for the transaction. If no `UserMargin` was included, the `FinalRate` is the same as the `ClientRate`.

### MarginsResponse

Information about the margins calculated for the transaction.

- `Mangopay` (MarginsResponseMangopay, optional) — The margin used by Mangopay to bill your platform (which is defined during contracting).
