Ethereum: I am trying to understand what exactly is signature query parameter in binance
Understanding the signature overview of the Binance -api
**
If you try to use the endpoint “User information” with the parameter Signature Survey, it is necessary to understand the concept of this function. This article divides what the Survey parameter is and how it implemented.
What is the parameter signature survey?
The parameter signature survey is a mechanism that is used in API inquiries that contain further information or information about your request. By defining this parameter as part of the URL questionnaire, you can transmit sensitive or non-standard information that is not included in the standard requirement.
In the case of the Binance user data endpoint, the parameter signature survey is used to access user -specific data without displaying it via the Standard API answer.
How to use the signature elevation parameter
Using the signature overview of the Parelia at the end of the “user information” at Binance:
- ** Add the parameter in URL: The format is:
&
2
Example request:
Here is an example of an inquiry that contains both the “SIG” frail delivery and some standard data:
`Json
`
Implementation in your code
Here is an example of the parameter for the processing of the code:
`Python
Bring your inquiries with you
Class Binnindatapi:
Def __init __ (self, base_url, api_key, api_secret):
Self.base_url = base_url
Self.api_key = api_key
Self.api_secret = api_secret
DEF GET_USER_DATA (yourself, symbol, quantity, time temple, page):
Create a requirement -URL with Signature Survey Parameter
url = f "{self.base_url}/api/v3/spot/userdata? sig = {selfet.get_signature ()} &"
Add other parameters to the request -OURL address
params = {
"Symbol": a symbol,
"Quantity": quantity,
"Time Temple": Time Temple,
"Page": page,
}
Answer = Requests.Get (url, params = params)
return response.json ()
DEF GET_Signature (self):
Create a signature based on your API key and your secret
Replace them with their real values
Api_key = self.api_key
Api_secret = self.api_secret
Signature = f "{api_Key}: {api_secret}"
Return the signature
Use example:
binance_user_data_api = binkuserdapi (" "your_api_key", "your_api_secret")
Symbol = "ETH"
Quantity = 1000.00
TIMESTAMP = 1643723903
Page = "offer"
User_data_Response = binance_user_data_api.get_user_data (symbol, quantity, time temple, page)
Print (user_data_response)
