Pagination
Parameter | Description |
---|---|
limit |
Number of results per call. |
offset |
Number of results offset. |
sort |
Sort direction. Accepted values: ASC (ascending order), DESC (descending order) |
by |
Filter type. Accepted values: id , timestamp |
from |
Interval initial value. If filter by timestamp is used, then parameter type is DateTime ; otherwise — Number . |

Interval end value. If filter by timestamp is used, then parameter type is DateTime ; otherwise — Number . |
RATE LIMITS
The maximum number requests per second (RPS) for specific calls can be limited by a rate limit and a burst limit.
The server will process a number of requests that do not exceed the sum of the rate limit and the burst limit within the 1-second sliding window.
If both limits in total are exceeded, an HTTP 429 response is returned.
Requests are being counted per call (REST endpoint or WebSocket message) and:
- per IP address — requests arrived from the same IP address regardless of the identity;
- per account — requests sent under the same identity regardless of an API key, session, connection or IP address.

BEST PRACTICES
The ChangellyPRO API development team strives to bring the best trading experience to API users. This manual contains a set of best practices for using the API as efficiently as possible.
Request Parameters
Pass a request payload (body) in POST requests and query parameters — in GET requests.
Passing parameters in a way different from the documentation is not supported.
HTTP Persistent Connection
The underlying TCP connection is kept active for multiple requests/responses. Subsequent requests will result in reduced latency as the TCP handshaking process is no longer required.
If you use the HTTP 1.0 client, please ensure it supports the Keep-Alive directive and submit the "Connection: Keep-Alive" header with a request.
Keep-Alive is a part of the HTTP/1.1 or HTTP/2 protocol and enabled by default on compliant clients. However, you will have to ensure your implementation does not set other values as the connection header.
Retrieving and Updating Account State
Use the Streaming API for real-time updates of orders, trades, and any transaction changes.

Authentication
Public market data are available without authentication. Authentication is required for other requests.
You should create API keys on the API Settings page. You can create multiple API keys with different access rights for your applications.
Basic
curl -u "apiKey:secretKey" "https://api.pro.changelly.com/api/3/wallet/balance"
import requests
session = requests.session()
session.auth = ("apiKey", "secretKey")
const fetch = require('node-fetch');
const credentials = Buffer
.from(
'apiKey'
+ ':'
+ 'secretKey'
)
.toString('base64');
fetch(
'https://api.pro.changelly.com/api/3/wallet/balance',
{
method: 'GET',
headers: {
'Authorization': 'Basic ' + credentials
}
}
);
To authorize, place credentials to the request header. Those must be constituted
of apiKey
and secretKey
as follows: "Basic " + apiKey + ":" + secretKey
.
HS256
from base64 import b64encode
from hashlib import sha256
from hmac import HMAC
from time import time
from urllib.parse import urlsplit
from requests import Session
from requests.auth import AuthBase
class HS256(AuthBase):
def __init__(self, api_key: str, secret_key: str, window: int = None):
self.api_key = api_key
self.secret_key = secret_key
self.window = window
def __call__(self, r):
url = urlsplit(r.url)
message = [r.method, url.path]
if url.query:
message.append('?')
message.append(url.query)
if r.body:
message.append(r.body)
timestamp = str(int(time() * 1000))
window = str(self.window) if self.window else None
message.append(timestamp)
if window:
message.append(window)
signature = HMAC(key=self.secret_key.encode(),
msg=''.join(message).encode(),
digestmod=sha256).hexdigest()
data = [self.api_key, signature, timestamp]
if window:
data.append(window)
base64_encoded = b64encode(':'.join(data).encode()).decode()
r.headers['Authorization'] = f'HS256 {base64_encoded}'
return r
auth = HS256(api_key='apiKey', secret_key='secretKey')
with Session() as s:
response = s.get('https://api.pro.changelly.com/api/3/wallet/balance', auth=auth)
print(response.json())
The alternative authentication method is the HMAC signature.
To send a request, you should establish a persistent session using the credentials signed as follows:
- Create an HMAC signature with
secret_key
as the secret key, SHA256 as the hash algorithm, and payload as the message, structured like:
<method> + <URL path> + [“?” + <query>] + [<body>] + <timestamp> + [<window>]
- Add the authorization header to a request. It should have the following
structure:
"HS256 " + Base64(api_key + ":" + <HMAC signature> + ":" + timestamp + [":" + window])

Response: spot order
Price accuracy and quantity
Symbol config contains the tick_size
parameter which means that price
should
be divided by tick_size
with no remainder.
quantity
should be divided by
quantity_increment
with no remainder.
By default, if strict_validate
is
not enabled, the Server rounds half down the price
and quantity
for
tick_size
and quantity_increment
.
Example of ETHBTC: if tick_size
is 0.000001
, then price 0.046016
is valid,
and 0.0460165
is invalid.
Fees
Charged fee is determined by the symbol's fee_currency
. Maker-taker fees offer
a transaction rebate make_rate
to those who provide liquidity (a maker), while
charging customers who take that liquidity take_rate
(a taker).
To create buy orders, you must have sufficient balance including fees.
To create market buy orders, you must have sufficient balance including fees.
Available balance > price × quantity + price × quantity × max(take_rate, make_rate)
Order result status
For orders with time_in_force
equal to IOC
or FOK
, the REST API returns
final order status: filled
or expired
.
If an order can be instantly executed, then the REST API returns a status of
filled
or partiallyFilled
in the order's info.

Risk limit = limit_base / ( L ^ limit_power )
,
where L
is a leverage set by the user.
Note that the resulting limit hedges the value of existing open orders (considering unfilled portion of their quantity) added to the position market value and the value of a new order.

Request Object
Request
{
"method": "spot_new_order",
"params": {
"client_order_id": "57d5525562c945448e3cbd559bd068c4",
"symbol": "ETHBTC",
"side": "sell",
"price": "0.059837",
"quantity": "0.015"
},
"id": 123
}
An RPC call is represented by sending a Request object to a Server.
The Request object has the following members:
-
method
— a String containing the name of the method to be invoked; -
params
— a Structured value that holds the parameter values to be used during the invocation of the method; -
id
— An identifier established by the Client that MUST contain a String, Number, ornull
value if included. If it is not included it is assumed to be a notification. The value SHOULD NOT benull
.
Notification
Notification
{
"ch": "trades",
"update": {
"BTCUSDT": [{
"t": 1626861123552,
"i": 1555634359,
"p": "30877.68",
"q": "0.00006",
"s": "sell"
}]
}
}
A Notification is a Request object without an id
member. A Request object (a
Notification) signifies the lack of the Client's interest in the corresponding
Response object. Therefore, no Response objects need to be returned to the
Client.
Response Object
When an RPC call is made, the server must reply with responses, except for notifications cases.
Response on success subscription is true
. Example:
Response
{
"result": true,
"id": 123
}
Response error
{
"error": {
"code": 2001,
"message": "Symbol not found",
"description": "Symbol not found"
},
"id": 123
}
The Response is represented as a single JSON Object, with the following members:
-
result
— this member is REQUIRED on success. This member MUST NOT exist if there was an error during method invocation. The value of this member is determined by the method invoked on the Server; -
error
— this member is REQUIRED on error. This member MUST NOT exist if there was no error triggered during method invocation. The value for this member MUST be an Object as defined in the "Error Response" section.
Socket Market Data
In order to access market data via WebSocket interface, connect to the endpoint:
wscat -c wss://api.pro.changelly.com/api/3/ws/public
Request
{
"method": "subscribe",
"ch": "orderbook/top/1000ms", // Channel
"params": {
"symbols": [
"ETHBTC",
"BTCUSDT"
]
},
"id": 123
}
From that point on, you will be able to send request messages in JSON format with the following parameters:
Name | Type | Description |
---|---|---|
method |
String | The name of the method to be invoked. Accepted values: subscribe , unsubscribe , subscriptions |
ch |
String | Channel name. |
params |
JSON | Parameter values to be used during the method invocation. The set of parameters may vary depending on the channel chosen. |
id |
String | Optional. Request identifier as assigned by sender. |
Response
{
"result": {
"ch": "orderbook/top/1000ms", // Channel
"subscriptions": [
"ETHBTC",
"BTCUSDT"
]
},
"id": 123
}
Any valid and successfully processed request will result in a JSON-formatted response message containing the following fields:
Name | Type | Description |
---|---|---|
result |
Result | Details about resulting subscription status. |
id |
String | Optional. Request identifier as assigned by sender. |
Result model consists of:
Name | Type | Description |
---|---|---|
ch |
String | Channel name. |
subscriptions |
[]String | List of active subscriptions. |
Subscriptions
In case of a successful subscriptions, the server will send:
- for
price/rate/{speed}
,ticker/price/{speed}
,ticker/{speed}
,orderbook/{depth}/{speed}
,orderbook/top/{speed}
,futures/info
: data notifications (data
) with a specified rate.{speed}
— the period of updating data which embraces the changes that have occurred if any; - for
trades
,orderbook/full
,candles/{period}
: snapshot (snapshot
) and update (update
) notifications.
In the second case, the first snapshot comes right after the response if the
limit
parameter is greater than 0. Snapshot gives a full account of the market
within the defined scope, and an update contains only recent changes which are
being sent immediately.
Batch Notifications
If a market data request includes a number of subscriptions, a choice of channel will determine the distribution of updates over incoming notifications.
In the basic scenario, a single notification will contain data on a particular
symbol only. Subscription to "batch" channels (ones ending with /batch
) allows
notifying via combined updates per multiple symbols.

Socket Trading
Trade via socket has some major differences compared to REST:
- quickness. The time to place a new order is a bit higher than network latency;
- the Server notifies you of any order updates;
- FIFO. Your requests are executed on a First In First Out basis.

Socket Wallet Management
Description
WebSocket Account API uses the same authorization approach as described in the Socket Session Authentication section.
API provides the following tools to manage a general account:
- a subscription to the transactions:
- any sequenced transaction changes such as creating or updating.
- a balance request;
- a transaction history request.
Subscribe to Transactions
Method: subscribe_transactions
and the corresponding unsubscription
method: unsubscribe_transactions
Income method: transaction_update
A full transaction model description can be found in the "Get Transactions History" section.
A subscription to the transactions has to be used rather than the transaction polling.
A transaction notification occurs each time the transaction has been changed, such as creating a transaction, updating the pending state (e.g., the hash assigned) or completing a transaction. This is the easiest way to track deposits or develop real-time asset monitoring.
