Introduction

API FixedFloat vous permet d'automatiser la réception d'informations sur les taux de change des devises, les commandes créées, présentées sur le service FixedFloat, de créer des commandes et de les gérer à l'aide de celle-ci.

Pour utiliser l'API FixedFloat, vous devez obtenir une API key et un API secret.

Obtenir la API key

Pour obtenir une API Key et un API Secret, suivez ces étapes:

  1. Connectez-vous ou Inscrivez-vous au FixedFloat
  2. Allez dans la section API management
  3. Cliquez sur le bouton "Générer" et suivez les instructions dans la fenêtre qui apparaît
  4. Copiez la API Key et le API Secret et conservez-les en lieu sûr. Utilisez ces paramètres pour les requêtes à l'API FixedFloat

Demande et exemple

Les données envoyées doivent être au format JSON avec encodage UTF-8.

Pour que les requêtes API aboutissent, toutes les requêtes doivent contenir quelques en-têtes obligatoires:

  • L'en-tête Content-Type doit être application/json; charset=UTF-8
  • L'en-tête X-API-KEY doit contenir votre API Key reçue (YOUR_API_KEY)
  • L'en-tête X-API-SIGN doit contenir la signature GENERATED_SIGN. Pour obtenir la signature, vous devez utiliser votre API Secret (YOUR_API_SECRET) comme clé d'opération HMAC SHA256 et la chaîne de données json comme valeur.

Limites de demande

La limite de demande par minute est de 250 unités.

La requête /api/v2/create coûte 50 unités, toutes les autres requêtes coûtent 1 unité.

Si la limite est dépassée, votre jeton sera temporairement bloqué. A chaque dépassement ultérieur de la limite après le déverrouillage, le temps de blocage augmentera

Taux de change

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

Obtenir le taux de change d'une paire de devises dans la direction et le type de taux sélectionnés.

ATTENTION ! Pour obtenir les taux de change de toutes les devises disponibles, vous devez utiliser le fichier d'exportation XML des taux

Pour cette méthode, ainsi que pour la méthode /api/v2/create, il est possible d'augmenter les revenus accumulés dans le cadre du programme d'affiliation en utilisant le paramètre afftax.

Le taux de change final lors du passage des paramètres afftax et refcode dépend de si votre code de programme d'affiliation a été approuvé pour gagner des commandes générées par l'API et du pourcentage de base (AFFBASE) défini pour votre code, et sera calculé selon la formule:

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

FF est le pourcentage de base du service pour le type de taux de change sélectionné (1% pour un taux fixe et 0,5% pour un taux variable);
AFFB est le pourcentage de base du bénéfice de service défini pour votre code de programme d'affiliation, pour le type de taux de change sélectionné (AFFBASE pour un taux fixe et AFFBASE÷2 pour un taux variable)

Pour plus de clarté, nous vous suggérons de vous familiariser avec le tableau ci-dessous avec AFFBASE=0.4, where 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

Si votre code d'affiliation n'a pas défini de pourcentage de revenus API de base, le taux de change final sera calculé comme suit:

FF + afftax

FF est le pourcentage de base du service pour le type de taux de change sélectionné (1% pour un taux fixe et 0,5% pour un taux variable).

Les gains seront crédités sur votre compte si le code du programme d'affiliation a été passé dans le paramètre refcode et que ce code appartient à votre compte. Sinon, les paramètres afftax et refcode seront ignorés.
