Writing your own GraphQL queries

Although the Buycoins SDK provides most, if not all, of the functionality that you will need in your apps, there are sometimes where you might want to write your own GraphQL queries

Here’s a simple guide on how to do that!

Steps

• Create a BuycoinsGraphqlClient object with your Buycoins API keys

  >>> from buycoins_sdk import BuycoinsGraphqlClient
  
  >>> bc_client = BuycoinsGraphqlClient(
      public_key=os.getenv('BUYCOINS_PUBLIC_KEY'),
      secret_key=os.getenv('BUYCOINS_SECRET_KEY')
  )
  

• Use the client attribute of your BuycoinsGraphqlClient instance to write your queries manually. The Buycoins SDK makes use of python_graphql_client to query the Buycoins API so you might want to check out the documentation for that

  >>> query = """
          query getEstimatedNetworkFee($cryptocurrency: Cryptocurrency, $amount: BigDecimal!){
              getEstimatedNetworkFee(cryptocurrency: $cryptocurrency, amount: $amount){
                  estimatedFee
                  total
              }
          }
      """
  >>> variables = {'cryptocurrency': enums.Cryptocurrency.BITCOIN.value, 'amount': '100'}
  >>> res = bc_client.client.execute(query=query, variables=variables)
