Can run this query at any stage to confirm the change in the balances.
The "BTC" wallet balance is denominated in satoshis.

The body of the GraphQL request

query Me {
  me {
    defaultAccount {

        id
        walletCurrency
        balance
      }
    }
  }
}
curl command to get the USD wallet ID
Generate a new address to receive USD​
Using Stablesats a merchant can generate and onchain address where the bitcoin received will be denominated in USD cents. 

Use the address from the response and send to it from any bitcoin wallet.

The received satoshi amount will reflect the USD/BTC exchange rate at the time it was received and the balance will be kept at the dollar value.

mutation onChainAddressCreate($input: OnChainAddressCreateInput!) {
  onChainAddressCreate(input: $input) {
    address
    errors {
      message
    }
  }
}
Set the USD wallet ID:
curl command to generate a new address
Once paid check the balance again​
The balance will be updated once the transaction is confirmed on the blockchain.

Until the confirmation the new incoming amount will show in the pendingIncomingBalance field.
