General Info

General API Information

The base endpoint is: https://vapi.binance.com
All endpoints return either a JSON object or array.
Data is returned in ascending order. Oldest first, newest last.
All time and timestamp related fields are in milliseconds.

HTTP Return Codes

HTTP 4XX return codes are used for malformed requests; the issue is on the sender’s side.
HTTP 403 return code is used when the WAF Limit (Web Application Firewall) has been violated.
HTTP 429 return code is used when breaking a request rate limit.
HTTP 418 return code is used when an IP has been auto-banned for continuing to send requests after receiving 429 codes.
HTTP 5XX return codes are used for internal errors; the issue is on Binance’s side.
HTTP 504 return code is used when the API successfully sent the message but not get a response within the timeout period. It is important to NOT treat this as a failure operation; the execution status is UNKNOWN and could have been a success.

Endpoint Error Codes

Any endpoint can return an ERROR
Specific error codes and messages defined in Error Codes.

General Information on Endpoints

For GET endpoints, parameters must be sent as a query string.
For POST, PUT, and DELETE endpoints, the parameters may be sent as a query string or in the request body with content type application/x-www-form-urlencoded. You may mix parameters between both the query string and request body if you wish to do so.
Parameters may be sent in any order.
If a parameter sent in both the query string and request body, the query string parameter will be used.

testnet environment

Most of the endpoints can be also used in the testnet platform.
The REST baseurl for testnet is https://testnet.binanceops.com
The Websocket baseurl for testnet is wss://testnetws.binanceops.com

Endpoint Security Type

Each endpoint has a security type that determines the how you will interact with it.
API-keys are passed into the Rest API via the X-MBX-APIKEY header.
API-keys and secret-keys are case sensitive.
API-keys can be configured to only access certain types of secure endpoints. For example, one API-key could be used for TRADE only, while another API-key can access everything except for TRADE routes.
By default, API-keys can access all secure routes.

Security Type	Description
NONE	Endpoint can be accessed freely.
TRADE	Endpoint requires sending a valid API-Key and signature.
USER_DATA	Endpoint requires sending a valid API-Key and signature.
USER_STREAM	Endpoint requires sending a valid API-Key.
MARKET_DATA	Endpoint requires sending a valid API-Key.

SIGNED (TRADE and USER_DATA) Endpoint Security

SIGNED endpoints require an additional parameter, signature, to be sent in the query string or request body.
Endpoints use HMAC SHA256 signatures. The HMAC SHA256 signature is a keyed HMAC SHA256 operation. Use your secretKey as the key and totalParams as the value for the HMAC operation.
The signature is not case sensitive.
Please make sure the signature is the end part of your query string or request body.
totalParams is defined as the query string concatenated with the request body.

Timing security

A SIGNED endpoint also requires a parameter, timestamp, to be sent which should be the millisecond timestamp of when the request was created and sent.
An additional parameter, recvWindow, may be sent to specify the number of milliseconds after timestamp the request is valid for. If recvWindow is not sent, it defaults to 5000.
If the server determines that the timestamp sent by the client is more than one second in the future of the server time, the request will also be rejected.

**Serious trading is about timing. ** Networks can be unstable and unreliable, which can lead to requests taking varying amounts of time to reach the servers. With recvWindow, you can specify that the request must be processed within a certain number of milliseconds or be rejected by the server.

Push Websocket account info

Base URL of the API interface listed in this article: https://vapi.binance.com A User Data Stream listenKey is valid for 60 minutes after creation. You can extend the validity period by 60 minutes by performing a PUT listenKey operation. You can immediately terminate the current data stream by performing a DELETE listenKey operation, which will render that listenKey invalid. Performing a POST operation on an account with a valid listenKey will return the current valid listenKey and extend its validity period by 60 minutes. The baseurl of the websocket interface is: wss://vstream.binance.com User Data Streams are accessed at /ws/ or /stream?streams= Each link can be valid for no more than 24 hours. Please be sure to handle disconnection/reconnection appropriately. Account data stream info is not guaranteed to be in strict chronological order. Please use the E field for sorting.

Data is compressed as a GZIP file by default. After successful connection, send {“method”:”BINARY”, “params”:[“false”], “id”:1} to convert to text data.

Generate Listen Key (USER_STREAM)

Start a new data stream. The data stream will be terminated after 60 minutes unless sending keepalive. If the account has a valid listenKey, the listenKey will be returned and the validity period will be extended by 60 minutes.
