Introduction

Setup

# make sure you have curl installed

Poloniex provides both HTTP and websocket APIs for interacting with the exchange. Both allow read access to public market data and private read access to your account. Private write access to your account is available via the private HTTP API.

The public HTTP endpoint is accessed via GET requests while the private endpoint is accessed via HMAC-SHA512 signed POST requests using API keys. Both types of HTTP endpoints return results in JSON format.

The websocket API allows push notifications about the public order books, lend books and your private account. Similarly to the HTTP API, it requires HMAC-SHA512 signed requests using API keys for requests related to your private account.

Getting Started

Sign Up

If you do not have a Poloniex account yet, use the button below to sign up.

Sign Up

Create an API Key

Once you are verified and have an account, you can create an API Key.

Enabling IP address restrictions for API keys is strongly recommended. Withdrawals are disabled by default and must be enabled on a per key basis.

As the name implies, your secret must remain private! If you suspect your key has been compromised, immediately disable that key and generate a new one.

Authenticate

# Find the HMAC-SHA512 signature of your POST parameters
# using your secret key. Set the nonce to the current
# milliseconds. (available with date +%s00000)
 echo -n "command=returnBalances&nonce=154264078495300" | \
openssl sha512 -hmac $API_SECRET
# You will use this signature as a header in your request.
# For example:
 curl -X POST \
     -d "command=returnBalances&nonce=154264078495300" \
     -H "Key: 7BCLAZQZ-HKLK9K6U-3MP1RNV9-2LS1L33J" \
     -H "Sign: 2a7849ecf...ae71161c8e9a364e21d9de9" \
     https://poloniex.com/tradingApi

Private HTTP endpoints are authenticated using HMAC-SHA512 signed POST request.

Private HTTP endpoints also require a nonce, which must be an integer greater than the previous nonce used. There is no requirement that nonces increase by a specific amount, so the current epoch time in milliseconds is an easy choice. As each API key has its own nonce tracking, using a different key for each client process can greatly simplify nonce management.

Minimize Latency

If you will be performing high-frequency trading, you may wish to locate your bots as close to our servers as possible. As Poloniex uses Cloudflare for all requests, you can minimize network latency by positioning your client near the Cloudflare gateway in Dublin, Ireland. You can identify which Cloudflare gateway your client is accessing by running this command on the same machine as your bot:

curl -s https://www.cloudflare.com/cdn-cgi/trace

Cloudflare’s Dublin data center will return a “colo” field of “DUB”. If you get a different “colo” value, you can look up the location at https://www.cloudflarestatus.com.

HTTP API

The HTTP API allows read access to public market data through the public endpoint and read / write access to your private account via the private endpoint.

Please note that there is a default limit of 6 calls per second. If you require more than this, please consider optimizing your application using the websocket-based push API, the "moveOrder" command, or the "all" parameter where appropriate.

Making more than 6 calls per second to the API, or repeatedly and needlessly fetching excessive amounts of data, can result in rate limit. Please be careful.

Public HTTP API Methods

The public HTTP API allows read access to public market data.

There are seven public methods, all of which take HTTP GET requests and return output in JSON format. No authentication is necessary but you must not excessively use any API endpoint.

Private HTTP API Methods

The private HTTP API allows read / write access to your private account.

All calls to the trading API are sent via HTTP using POST parameters to https://poloniex.com/tradingApi and must contain the following headers:

Additionally, all queries must include a "nonce" POST parameter. The nonce parameter is an integer which must always be greater than the previous nonce used and does not need to increase by one. Using the epoch in milliseconds is an easy choice here but be careful about time synchronization if using the same API key across multiple servers.

All responses from the trading API are in JSON format. In the event of an error, the response will always be of the following format:

{ "error": "<error message>" }

When placing orders there are currently the following minimum order sizes according to the quote currency.

Quote Minimum Total Order
BTC 0.0001
ETH 0.0001
USD (any) 1
TRX 100
BNB 0.06

There are several methods accepted by the trading API, each of which is specified by the "command" POST parameter:

returnBalances

# Note: set the nonce to the current milliseconds. For example: date +%s00000
echo -n "command=returnBalances&nonce=154264078495300" | \

Returns all of your deposit addresses.

Some currencies use a common deposit address for everyone on the exchange and designate the account for which this payment is destined by including a payment ID field. In these cases, use returnCurrencies to look up the mainAccount for the currency to find the deposit address and use the address returned here in the payment ID field. Note: returnCurrencies will only include a mainAccount property for currencies which require a payment ID.

In these cases, use returnCurrencies to look up the mainAccount for the currency to find the deposit address and use the address returned here in the payment ID field. Note: returnCurrencies will only include a mainAccount property for currencies which require a payment ID.

Input Fields

Field Description
currency The currency to use for the deposit address.

Output Field

Field Description
success Denotes the success or failure of the operation.
response The newly created address.

Immediately places a withdrawal for a given currency, with no email confirmation. In order to use this method, withdrawal privilege must be enabled for your API key. Required POST parameters are "currency", "amount", and "address".

For withdrawals which support payment IDs, (such as XMR) you may optionally specify a "paymentId" parameter.

For currencies where there are multiple networks to choose from (like USDT or BTC), you can specify the chain by setting the "currency" parameter to be a multiChain currency name, like USDTTRON, USDTETH, or BTCTRON. You can get information on these currencies, like fees or if they're disabled, by adding the "includeMultiChainCurrencies" optional parameter to the returnCurrencies endpoint. The previous method of choosing a network using the optional "currencyToWithdrawAs" parameter will continue to function as it used to, but is no longer recommended.

Places a margin sell order in a given market. Required POST parameters are "currencyPair", "rate", and "amount". You may optionally specify a maximum lending rate using the "lendingRate" parameter. (the default "lendingRate" value is 0.02 which stands for 2% per day) Note that "rate" * "amount" must be > 0.02 when creating or expanding a market. If successful, the method will return the order number and any trades immediately resulting from your order.

Input Fields

Field Description
currencyPair A string that defines the market, "USDT_BTC" for example.
rate The price. Units are market quote currency. Eg USDT_BTC market, the value of this field would be around 10,000. Naturally this will be dated quickly but should give the idea.
lendingRate The interest rate you are willing to accept per day. (default is 0.02 which stands for 2% per day)
amount The amount of currency to sell.
clientOrderId (optional) 64 bit Integer value used for tracking order across http responses as well as "o", "n" & "t" web socket messages. Must be unique across all open orders for each account.

Websocket API

# Install your favorite websocket command line tool.
# Our examples use https://github.com/hashrocket/ws
# which can be installed with this command:

go get -u github.com/hashrocket/ws

Websockets can be read by any standard websocket library. Data is organized into channels to which an API client may subscribe.

Requests and Responses

There are two type of requests supported; subscribe and unsubscribe. The requests are for a specific channel. For non-book requests, the first response is always an acknowledgement of the request. All channel updates are of the following format

[<channel>, <sequence id>, <update data...>]

<sequence id> is a number increasing by one with each update and is unique within its channel. The sequence-id is always null for non-book channels.

Subscribing and Unsubscribing

# Public channels
ws wss://api2.poloniex.com
> {"command": "subscribe", "channel": 1002}

# Private channels
# Note: set the nonce to the current milliseconds. For example: date +%s00000
echo -n "nonce=154264078495300" | openssl sha512 -hmac $API_SECRET
ws wss://api2.poloniex.com
> {"command": "subscribe", "channel": 1000, "sign": "e832d65f...8a522df8", "key": "7BCLAZQZ-HKLK9K6U-3MP1RNV9-2LS1L33J", "payload": "nonce=154264078495300"}

To receive updates from a channel you must subscribe to it. To subscribe to a public channel (all except the account notifications channel), determine its channel ID (provided with the description of each channel, and summarized here), send a JSON message in the following format:

{ "command": "subscribe", "channel": "<channel id>" }

To subscribe to a private channel, the parameters described in the authentication section are required in the subscription message. Just like the trading API, an integer nonce must be chosen that is greater than the previous nonce used; for this purpose the current epoch time in milliseconds is a reasonable choice. As each API key has its own nonce tracking, using a different key for each client process can greatly simplify nonce management. If the chosen nonce is 1234, provide a "payload" parameter consisting of nonce=1234, a "key" parameter with your API key, and a "sign" parameter with the HMAC-SHA512 signature of the payload signed by your secret:

{ "command": "subscribe", "channel": "<channel id>", "key": "<your API key>", "payload": "nonce=<epoch ms>", "sign": "<hmac_sha512(secret).update("nonce=<epoch ms>").hexdigest()>" }

In all cases the first message will be an acknowledgement of the subscription:

[<channel id>, 1]

To unsubscribe, send an unsubscribe message with the channel ID:

{ "command": "unsubscribe", "channel": <channel id> }

Channel Descriptions

The following <channel ids> are supported:

Channel Type Name
1000 Private Account Notifications (Beta)
1002 Public Ticker Data
1003 Public 24 Hour Exchange Volume
1010 Public Heartbeat
<currency pair> Public Price Aggregated Book

Additionally, as described below, each market has its own aggregated book channel.

< [1000,"",[["o",807230187,"0.00000000", "f"],["b",267,"e","0.10000000"]]]

The account notifications channel (id 1000) provides real-time updates of trade and balance changes on your account. You can (and should) use it to track your account's trading activity (instead of relying on repeated calls to the trading API). It is an authenticated websocket endpoint, so subscribing to it requires the parameters discussed in the subscribing section:

{ "command": "subscribe", "channel": "1000", "key": "<your API key>", "payload": "nonce=<epoch ms>", "sign": "<hmac_sha512(secret).update("nonce=<epoch ms>").hexdigest()>" }

The first message is acknowledgement of the subscription.

[1000, 1]

Subsequent messages represent updates to your account. In general, a message consists of a combination of updates of different types. Each update is an array of data, where the first element is a character denoting the type of the update, and subsequent elements are various parameters:

[ 1000, null, [ ["b", DATA_1, DATA_2, DATA_3], ["n", DATA_1, DATA_2, DATA_3, DATA_4, DATA_5, DATA_6] ] ]

A given message may contain multiple updates, multiple types of updates, and multiple updates of the same type. There is no ordering guarantee of update types within a single message. Effectively, each message is a record of all of the changes to your account induced by a single action. There are four types of updates, as described below:

Order type Amount Interpretation
f > 0.00000000 partially filled order
f = 0.00000000 completely filled order
c > 0.00000000 partially cancelled order
c = 0.00000000 completely cancelled order
s > 0.00000000 partially filled self-trade
s = 0.00000000 completely filled self-trade

Thus, an o update representing a partially filled limit order with a new amount of 1.5 and a clientOrderId of 12345 will look like: ["o", 6083059, "1.50000000", "f", "12345"].

As mentioned above, a single logical action may cause a message with multiple updates. For instance, placing a limit order to buy ETH using BTC, which is immediately partially fulfilled, will cause an update with 5 parts: a p message with the newly placed pending order for the BTC_ETH market, a b update with a positive ETH balance (the ETH that was immediately bought), a b update with a negative BTC balance update (the BTC removed from the user's funds to pay for the ETH), a t update representing the trade in which the order was partially fulfilled and then the remaining amount becomes open, and an n update with the new limit order for the rest of the requested ETH.

Note that many actions do not have explicit notification types, but rather are represented by the underlying trade and balance changes:

There are currently no notifications of transfers between wallets initiated via the transfers page or the transferBalance trading API call.

Subscribe to price aggregated depth of book by currency pair. Response includes an initial book snapshot, book modifications, and trades. Book modification updates with 0 quantity should be treated as removal of the price level. Note that the updates are price aggregated and do not contain individual orders.

Subscription example for BTC_BTS pair (id is 14). You can either subscribe using the currency pair ID or name. Currency pair IDs are listed in the currency pair ID list.

{ "command":"subscribe", "channel": 14 }

Or

{ "command": "subscribe", "channel": "BTC_BTS" }

The first response is the initial dump of the book. NOTE: An "i" message can occur after the initial subscription under certain circumstances. When this occurs the client is required to reset the state of the price aggregated book.

[ <channel id>, <sequence number>, [ [ "i", { "currencyPair": "<currency pair name>", "orderBook": [ { "<lowest ask price>": "<lowest ask size>", "<next ask price>": "<next ask size>", ... }, { "<highest bid price>": "<highest bid size>", "<next bid price>": "<next bid size>", ... } ] } ] ] ]

For example:

[ 14, 8767, [ [ "i", { "currencyPair": "BTC_BTS", "orderBook": [ { "0.00001853": "2537.5637", "0.00001854": "1567238.172367" }, { "0.00001841": "3645.3647", "0.00001840": "1637.3647" } ] } ] ] ]

Subsequent responses are updates to the book and trades

[ <channel id>, <sequence number>, [ ["o", <1 for bid 0 for ask>, "<price>", "<size>"], ["o", <1 for bid 0 for ask>, "<price>", "<size>"], ["t", "<trade id>", <1 for buy 0 for sell>, "<price>", "<size>", <timestamp>] ] ... ]

For example

[ 14, 8768, [ ["o", 1, "0.00001823", "5534.6474"], ["o", 0, "0.00001824", "6575.464"], ["t", "42706057", 1, "0.05567134", "0.00181421", 1522877119] ] ]
