Introduction
Welcome to the Crypto.com Exchange V2 API reference documentation.
The Crypto.com Exchange provides developers with a REST and websocket API.
The majority of API calls are available across both mediums in the same request and response formats, allowing smooth transition and a reduced learning curve between the two platforms.
Where applicable, all API calls come with detailed information on both the request and response parameters, all in a simple JSON format, as well as sample requests and code snippets in JavaScript, Python, C#, and Java which can be viewed on the right.
Documentation for the old REST API V1 can be found here.

Generating the API Key
Before sending any requests, you'll need to generate a new API key.
This can be done in the Exchange website under User Center - API.
After generating the key, there are two things you need to carefully note down:
- API Key
- Secret Key
API Key and Secret are randomly generated by the system and can not be modified. Default settings will be set to "Can Read" only, and you have the option of adding or removing certain permissions for your API Key via Web UI.
You can optionally specify a whitelist of IP addresses when generating the API Key.
If specified, the API can only be used from the whitelisted IP addresses.
Rate Limits
REST API
For authenticated calls, rate limits are per API method, per API key:
| Method | Limit |
|---|---|
private/create-orderprivate/cancel-orderprivate/cancel-all-ordersprivate/margin/create-orderprivate/margin/cancel-orderprivate/margin/cancel-all-orders |
15 requests per 100ms each |
private/get-order-detailprivate/margin/get-order-detail |
30 requests per 100ms |
private/get-tradesprivate/margin/get-trades |
1 requests per second |
private/get-order-historyprivate/margin/get-order-history |
1 requests per second |
| All others | 3 requests per 100ms each |
For public market data calls, rate limits are per API method, per IP address:
| Method | Limit |
|---|---|
public/get-bookpublic/get-tickerpublic/get-trades |
100 requests per second each |
Websocket
| Websocket | Limit |
|---|---|
| User API | 150 requests per second |
| Market Data | 100 requests per second |
private/get-trades and private/get-order-history is rate limited at 5 requests per second on the Websocket
We recommend adding a 1-second sleep after establishing the websocket connection, and before requests are sent.
This will avoid occurrences of rate-limit (`TOO_MANY_REQUESTS`) errors, as the websocket rate limits are pro-rated based on the calendar-second that the websocket connection was opened.
REST API Root Endpoint
REST API v1 and v2 have separate endpoints.
Future versions will share the same endpoint as v2, but with the version incremented.
Documentation for the old REST API V1 can be found here.

Common API Reference
Most of the APIs for REST and Websockets are shared, and follow the same request format and response, allowing users to easily switch between the two methods.
The Applies To section under each API allows you to see which platform supports the API.
Naming Conventions
All methods and URLs in dash-case
All parameters in snake_case
Enums in full uppercase and snake_case

For REST API, only the private methods require a Digital Signature (as "sig") and API key (as "api_key") to be passed in. These private endpoints are only accessible by authenticated users.
For Websocket (User API), the public/auth command has to be invoked ONCE per session, with the Digital Signature (as "sig") and API key (as "api_key") as part of the request. Once authenticated, you will gain access to user-specific commands, and no longer need to use the pass in the Digital Signature and API key anymore for the duration of the session.
The authentication is based on the pairing of the API Key, along with the HMAC-SHA256 hash of the request parameters using the API Secret as the cryptographic key.
The algorithm for generating the HMAC-SHA256 signature is as follows:
If "params" exist in the request, sort the request parameter keys in ascending order.
Combine all the ordered parameter keys as
key+value(no spaces, no delimiters). Let's call this theparameter stringNext, do the following:
method+id+api_key+parameter string+nonceUse HMAC-SHA256 to hash the above using the API Secret as the cryptographic key
Encode the output as a hex string -- this is your Digital Signature
Digital Signature Issues
Based on the language, and the way data-types are handled, the digital signature may be incorrectly calculated for certain values.
One known case is if parameters contain numbers, and the value passed in is a whole numbers that still has decimal suffixes, e.g. 8000.000 instead of 8000.
When the JSON request is sent to the server, the client (when parsing as JSON) may cast the number 8000.000 as 8000 automatically, which is what the server would see.
However, the digital signature may have been calculated using 8000.000 in the payload, which would result in a digital signature mismatch.
If this scenario happens in your case, there are three options:
Don't allow whole number values to have decimals
Ensure the payload casts number values properly before concatenating
Wrap the values in quotation marks to make them strings -- this is allowed by the server even if the parameter is marked as a number data type

Error Response Format
Due to the asynchronous nature of websocket requests, a robust and consistent error response is crucial in order to match the response with the request.
To ensure API consistency for websocket error responses, if the id and method is omitted in the original request, id will have a value of -1 and method will have a value of ERROR.
The original request will be returned as an escaped string in the original field.
public/auth
Request Sample
{
"id": 11,
"method": "public/auth",
"api_key": "api_key",
"sig": "d0267b151db609885bad2e4f8ad07610f7913e166c35adaf5697d59a64e3755a",
"nonce": :1587846358253
}
Response Sample
{
"id":11,
"method":"public/auth",
"code":0
}
To access user-specific websocket methods, public/auth has to be invoked with a valid API key and Digital Signature (refer to the Digital Signature section).
REST API calls do NOT need to do this.
We recommend adding a 1-second sleep after establishing the websocket connection, and before requests are sent.
This will avoid occurrences of rate-limit (`TOO_MANY_REQUESTS`) errors, as the websocket rate limits are pro-rated based on the calendar-second that the websocket connection was opened.

Gets the order history for a particular instrument
If paging is used, enumerate each page (starting with 0) until an empty order_list array appears in the response.
Users should use user.order to keep track of real-time order updates, and private/get-order-history should primarily be used for recovery; typically when the websocket is disconnected.
Request Params
| Name | Type | Required | Description |
|---|---|---|---|
| instrument_name | string | N | e.g. ETH_CRO, BTC_USDT. Omit for 'all' |
| start_ts | long | N | Start timestamp (milliseconds since the Unix epoch) - defaults to 24 hours ago |
| end_ts | long | N | End timestamp (milliseconds since the Unix epoch) - defaults to 'now' |
| page_size | int | N | Page size (Default: 20, max: 200) |
| page | int | N | Page number (0-based) |
Note: If you omit all parameters, you still need to pass in an empty params block like params: {} for API request consistency
Maximum Duration
The maximum duration between start_ts and end_ts is 24 hours.
You will receive an INVALID_DATE_RANGE error if the difference exceeds the maximum duration.
For users looking to pull longer historical order data, users can create a loop to make a request for each 24-period from the desired start to end time.

Websocket Subscriptions
Introduction
Request Sample
{
"id": 11,
"method": "subscribe",
"params": {
"channels": ["user.order.ETH_CRO"]
},
"nonce": 1587523073344
}
Response Sample (Initial)
{
"id": 11,
"code": 0,
"method": "subscribe"
}
One of the powerful features of a websocket is the ability to subscribe to incremental updates in particular channels.
This section covers the available channels that can be subscribed or unsubscribed for both the Websocket (User API) and Websocket (Market Data Subscriptions)
Market Data Subscriptions include features such as order book depth, all trades and ticker data. Market data information is pushed every 100 milliseconds.
Websocket subscriptions involve two responses:
An initial response to the subscribe command, which can subscribe to one or more channels
Periodic channel data for the specified channel
We recommend adding a 1-second sleep after establishing the websocket connection, and before requests are sent.
This will avoid occurrences of rate-limit (`TOO_MANY_REQUESTS`) errors, as the websocket rate limits are pro-rated based on the calendar-second that the websocket connection was opened.
Request Params
| Name | Type | Required | Description |
|---|---|---|---|
| method | string | Y | subscribe, unsubscribe |
| channels | array of strings | Y | Channels to be subscribed |

Common Issues
TOO_MANY_REQUESTS After Websocket Connects
Websocket rate limits are pro-rated based on the calendar-second that the websocket connection was opened.
This means, depending on the fraction of the calendar-second that the connection was established, the rate limit could be pro-rated to a small number.
By adding a 1-second sleep after establishing the websocket connection, and before requests are sent, this will ensure the rate limit is properly reset and sync'd to your session.
This will avoid occurrences of rate-limit (TOO_MANY_REQUESTS) errors.
INVALID_NONCE On All Requests
The nonce should be the UTC Unix timestamp in milliseconds.
If this has been carefully checked, then the issue occurs when the system clock of the client machine is greater than 1 second in the future, or 30 seconds in the past.
Usually, re-syncing with the NTP time server on the client machine will correct the issue.
If the issue persists, you can try deliberately subtracting 5 seconds from the nonce to force it to be 5 seconds in the past, which is still within the 30-second past tolerance.
