So you’re an advanced cryptocurrency trader or maybe an app developer who wants to seamlessly plug into every major exchange. You have a general understanding of the API landscape, but might not have known the power of using Shrimpy to manage all of your exchange API connections. Keep reading! In this article, we’ll be showing you how to set up cryptocurrency trading using APIs. This process can be repeated for every major exchange due to the universal developer tools provided by Shrimpy. The alternative being libraries like CCXT, which require you to write custom code for every exchange, manage infrastructure, and scale a farm of servers which executes trades and collects data across every exchange. Shrimpy vs CCXT: The Case for Centralization in a Decentralized Ecosystem Create & Connect your API Key Before we guide you through the steps of API trading, you will need to create exchange API Keys. Detailed instructions on how to generate exchange API keys can be found . here Linking Bittrex API Keys [Tutorial] Shrimpy Crypto Trading API The Shrimpy Universal Crypto Exchange APIs connect to every major exchange. This provides a unified interface to interact with exchanges. Instead of learning the quirks and unique issues of every individual exchange, the Shrimpy Developer APIs can be used to prevent these irregularities. Instead of managing user API keys and connections to every exchange, developers can directly store API Keys with Shrimpy and even trade on top of Shrimpy’s unified interface. Our journey begins at the Shrimpy developer APIs. Shrimpy | Crypto Trading APIs for Developers Register for your Developer Account Using the Shrimpy Universal Crypto Exchange API requires you to first register with the Shrimpy developer platform . It’s free to sign up and everyone gets 10 free credits, which is enough for 10 months of testing the developer APIs. here Create Master API Keys You will first have to create a new to use the Shrimpy API. You must also have enabled in API Master Key Multi-Factor Authentication Settings. In the developer dashboard, select Verify your account by submitting an API Key request to your email. Complete the email request verification and return to the developer dashboard. Create API Master Key. Under ou should now see a new set of private/public These keys communicate with Shrimpy to create users, authorize subscriptions, and execute trades. For security reasons, you will have to verify your account through 2FA again to view the . Copy and save both the and API Keys, y API Keys. Private API Key Public Key Private Key. : Keep your public and private key secure! The master keys should never be shared with anyone. If you would like users to be able to trade on their own devices, the master keys can be used to generate user keys. The user keys are intended to be shared with users. We will discuss this in more detail in the next sections. Note Within your Master API Key Settings, you will be able to add IP Whitelists and enable specific API Key functions, separated into and Let’s go over these functions in detail. User, Account, Trade. User Settings (Create a User/User API Key) Create a User Before you can start trading, we need to create a user who can interact with the exchange. This is easy to do with Shrimpy! Note: These requests are signed with the master API keys. Request POST https://dev-api.shrimpy.io/v1/users Request Body {
    "name": "customnameforthisuser"
} Response {
    "id": "701e0d16-1e9e-42c9-b6a1-4cada1f395b8"
} Create a User API Key User API Keys can also be created for each user. Unlike Master API Keys, User API Keys are specifically designed to manage an individual user and can be shared with the associated user. This allows them to manage their own personal account with these keys by directly sending requests to Shrimpy. Multiple exchange accounts can be linked to a single user API key. Therefore allowing one user to manage countless exchange accounts with a single user API key. This user API key can execute trades, collecting account information, or accessing full order book data across every connected exchange. Note: These requests are signed with the master API keys Request POST https://dev-api.shrimpy.io/v1/users/<userId>/keys Request Example: POST https://dev-api.shrimpy.io/v1/users/701e0d16-1e9e-42c9-b6a1-4cada1f395b8/keys Response: {
    "publicKey": "51ac18b7d208f59b3c88acbb1ecefe6ba6be6ea4edc07e7a2450307ddc27ab80",
    "privateKey": "85c977ef4070f1deee70192ba7fd5a6caf534f891e4918cfffec11cd6b625e77db4f80347cb436bcaa8882231bacb02f0798a696f101fdd1ef268d66fc63c213"
} Account Settings In order to complete setup for trading, we also need to link an exchange account that we’ll be using to trade. Similar to our earlier example, we’ll be using Bittrex as the exchange we want to link. Note: These requests can be signed with the user API keys. Connect an Exchange Account Request POST https://dev-api.shrimpy.io/v1/users/<userId>/accounts Request Example POST https://dev-api.shrimpy.io/v1/users/701e0d16-1e9e-42c9-b6a1-4cada1f395b8/accounts Request Body {
    "exchange": "bittrex",
    "publicKey": "GOelL5FT6TklPxAzICIQK25aqct52T2lHoKvtcwsFla5sbVXmeePqVJaoXmXI6Qd",
    "privateKey": "SelUuFq1sF2zGd97Lmfbb4ghITeziKo9IvM5NltjEdffatRN1N5vfHXIU6dsqRQw",
} Response {
    "id": 1234
} Perfect! Now we have our user all set up. Let’s start trading! Trading Account Balances In order to know which assets an account is holding on an exchange, we need to collect balance data. This can be done easily with Shrimpy. Note: These requests can be signed with user API keys. Request GET https://dev-api.shrimpy.io/v1/users/<userId>/accounts/<exchangeAccountId>/balance Request Example GET https://dev-api.shrimpy.io/v1/users/701e0d16-1e9e-42c9-b6a1-4cada1f395b8/accounts/123/balance Response {
  "retrievedAt": "2019-01-09T19:17:33.000Z",
  "balances": [
    {
      "symbol": "KCS",
      "nativeValue": 2306,
      "btcValue": 0.33486579,
      "usdValue": 1327.8775274784
    },
    {
      "symbol": "ETH",
      "nativeValue": 4.0e-8,
      "btcValue": 1.4960564e-9,
      "usdValue": 5.9324652822859e-6
    }
  ]
} Awesome! It was that simple to get the balances for our exchange account. Execute Trades Let’s see how easy it is to perform a trade with Shrimpy. We will use the following endpoint: Request POST https://dev-api.shrimpy.io/v1/users/<userId>/accounts/<exchangeAccountId>/trades This endpoint provides a simple method to execute a single trade through the Shrimpy APIs. All we will need to do is specify the “from” asset, the “to” asset, and the “amount”. With this information, Shrimpy will intelligently route your trades through quote currencies (if necessary) to accomplish the trade. Note: These requests can be signed with the user API keys. Request Example POST https://dev-api.shrimpy.io/v1/users/701e0d16-1e9e-42c9-b6a1-4cada1f395b8/accounts/123/trades Request Body {
    "fromSymbol": "BTC",
    "toSymbol": "ETH",
    "amount": "0.01",
} That’s it! You have now successfully submitted a trade through Shrimpy’s Trading API. Wasn’t that a piece of cake? Now that we’ve gone through the process to execute a trade, let’s explore some other useful endpoints that are available.
