API | FixedFloat

Einführung

Die FixedFloat-API ermöglicht es Ihnen, den Empfang von Informationen über die Wechselkurse von Währungen, erstellten Aufträgen, die im FixedFloat-Dienst präsentiert werden, zu automatisieren, Aufträge zu erstellen und sie damit zu verwalten.

Um die FixedFloat-API zu verwenden, müssen Sie einen API key und ein API secret abrufen.

Abrufen des API key

Gehen Sie folgendermaßen vor, um einen API Key und ein API Secret zu erhalten:

Einloggen oder Anmelden im FixedFloat
Gehen Sie zum Abschnitt API management
Klicken Sie auf die Schaltfläche "Generieren" und folgen Sie den Anweisungen im erscheinenden Fenster
Kopieren Sie den API Key und das API Secret und bewahren Sie diese an einem sicheren Ort auf. Verwenden Sie diese Parameter für Anforderungen an die FixedFloat-API

Anfrage und Beispiel

Die gesendeten Daten müssen im JSON-Format mit UTF-8-Kodierung vorliegen.

Für erfolgreiche API-Anfragen müssen alle Anfragen einige obligatorische Header enthalten:

Der Content-Type header muss application/json; charset=UTF-8
Der X-API-KEY Header sollte Ihren erhaltenen API Key (YOUR_API_KEY) enthalten
Der X-API-SIGN muss die Signatur GENERATED_SIGN enthalten. Um die Signatur zu erhalten, müssen Sie Ihr API Secret (YOUR_API_SECRET) als HMAC SHA256 Operationsschlüssel und die json Datenzeichenfolge als Wert verwenden.

X-API-SIGN generation

Curl Python PHP

Wechselkurs

POSThttps://ff.io/api/v2/price

Erhalten des Wechselkurses eines Währungspaares in der ausgewählten Richtung und Art des Kurses.

ACHTUNG! Um die Wechselkurse aller verfügbaren Währungen zu erhalten, sollten Sie die XML-Exportdatei der Kurse verwenden

Für diese Methode sowie für die Methode /api/v2/create ist es möglich, die verdienten Einnahmen im Rahmen des Partnerprogramms durch den Parameter afftax zu erhöhen.

Der endgültige Wechselkurs bei Übergabe der Parameter afftax und refcode hängt davon ab, ob Ihr Partnerprogrammcodes für die Erträge von API-generierten Bestellungen genehmigt wurde und dem Basisprozentsatz (AFFBASE), der für Ihren Code festgelegt ist, und wird nach folgender Formel berechnet:


total = FF - AFFB + afftax, if afftax < FF - AFFB
total = afftax x 2        , if FF - AFFB < afftax < FF
total = FF + afftax       , if afftax > FF

wo FF der Basisprozentsatz des Dienstes für die ausgewählte Art des Wechselkurses ist (1 % für einen festen Kurs und 0,5 % für einen variablen Kurs);
AFFB ist der Basisprozentsatz des Dienstgewinns, der für Ihren Partnerprogrammcodes festgelegt ist, für die ausgewählte Art des Wechselkurses (AFFBASE für einen festen Kurs und AFFBASE÷2 für einen variablen Kurs)

Zur Verdeutlichung empfehlen wir, dass Sie sich mit der nachstehenden Tabelle vertraut machen, wobei AFFBASE=0,4 ist, wo FFP = FF - AFFB:

FIXED RATE			FLOAT RATE
Total	FFP	afftax	Total	FFP	afftax
1.0	0.6	0.4	0.5	0.3	0.2
1.1	0.6	0.5	0.55	0.3	0.25
1.2	0.6	0.6	0.6	0.3	0.3
1.4	0.7	0.7	0.7	0.35	0.35
1.6	0.8	0.8	0.8	0.4	0.4
1.8	0.9	0.9	0.9	0.45	0.45
2.0	1.0	1.0	1.0	0.5	0.5
2.1	1.0	1.1	1.05	0.5	0.55
2.2	1.0	1.2	1.1	0.5	0.6

Wenn Ihr Partnerprogrammcode keinen Basisprozentsatz für API-Erträge hatte, wird der endgültige Wechselkurs wie folgt berechnet:


FF + afftax

wo FF der Basisprozentsatz des Dienstes für die ausgewählte Art des Wechselkurses ist (1 % für einen festen Kurs und 0,5 % für einen variablen Kurs).

Die Einnahmen werden Ihrem Konto gutgeschrieben, wenn der Partnerprogrammcode im Parameter refcode übergeben wurde und dieser Code zu Ihrem Konto gehört. Andernfalls werden die Parameter afftax und refcode ignoriert.

Parameter

Name	Required	Type	Description
type	true	string	Order type
fromCcy	true	string	Code of the currency the client wants to send
toCcy	true	string	Code of the currency the client wants to receive
direction	true	string	The direction of the exchange determines whether the client wants to send a certain amount or receive a certain amount. Can take one of the following values: ● from — if the client wants to send the amount amount in the currency fromCcy ● to — if the client wants to receive the amount amount in the currency toCcy
amount	true	numeric	If direction="from", then this is the amount in currency fromCcy that the client wants to send. If direction="to", then this is the amount in currency toCcy that the client wants to receive
ccies	false	boolean	Adding a list of currencies to the response with information about the availability for sending and receiving
usd	false	boolean	Amount in USD, by which fromAmount or toAmount will be changed in case the limits are exceeded
refcode	false	string	Affiliate program code for which earnings will be accrued under the affiliate program. If the afftax parameter is not set and this affiliate program code does not participate in earning via the API, passing this parameter will not affect anything. It is possible to transfer only affiliate program codes that were received in the same account in which the API key used for this request was received
afftax	false	float	Desired earnings under the affiliate program as a percentage of the exchange amount. Affects the final exchange rate and earnings under the affiliate program if the refcode parameter is also set.
