Installation

npm i buycoins-graphql-sdk

Authentication

To access the Buycoins API, you will need to generate a public and a secret key on thr API Settings screen in the Buycoins app. You can enable this feature by sending a request to support@buycoins.africa.

From the Buycoins API documentation:

The API is currently open to access requests from fully verified BuyCoins users. To apply, please send an email to support@buycoins.africa from your email account registered on BuyCoins.

Quick Start

To create a naira deposit account:

import { Buycoins } from 'buycoins-graphql-sdk'

// Pass in the public and secret key when creating a new instance.
var buycoinsClient = new Buycoins(process.env.PUBLIC_KEY, process.env.SECRET_KEY)

// The SDK is promise based :). You can also use async/await
buycoinsClient.nairaAccount.createDepositAccount({
    accountName: "somtochi test"
})
.then(data => {
    // TODO: Handle data
})
.catch(err => {
   // TODO: Handle error
})

That's it!

Usage

The SDK models the API and each property in the Buycoins class from the SDK matches with a section in the Buycoins API documentation.

    amount: 0.01, 
    crypto: "bitcoin", 
  }

Run your own GraphQL queries

If we are yet to implement some features or you want to run some customized queries outside what the API provides. You can access the query function.

buycoins.api.request(`query{
  getPrices{
    id
    cryptocurrency
    buyPricePerCoin
    minBuy
    maxBuy
    expiresAt
  }
}`)

You can pass in options to the query:

const options = {
  name: "wanda"
}

buycoins.api.request(`mutation($name: String!) {
  createDepositAccount(accountName: name) {
    accountNumber
    accountName
    accountType
    bankName
    accountReference
  }
}`, options)
