API Ethereum Request Edition at Binance
As a developer who works with Ethereum’s intelligent contracts, you strongly trust APIs to interact with Binance exchange. However, finding an error when making a requirement is not uncommon. In this article, we will explore the problem you are facing when using Universal Transfer Call for Binance’s API.
The problem: the compulsory parameter ‘type’ was not sent
By building your request from the Ethereum API, sems that one of the necessary parameters, ‘type’, has been omitted or missing in your consultation. This supervision can prevent your application from successfully processing the transaction.
To better understand the situation, we will examine how binance deals with the universal transfer call and identify what can be caused by the problem.
Binance API request structure
The Universal Transfer API to the Binance API requires three parameters:
Active: cryptocurrency being transferred (for example, Ethereum).
- Value
: The amount of cryptocurrency to transfer.
- Type
: The type of transaction, which can be one of the following:
*Send: Transfers funds from your account to another user.
*RECEIVING: Transfers funds from another user to your wallet.
The question: Mandatory parameter 'type' was not sent
In your case, it seems that you are missing or sending an empty value to the parameterType. This can be caused by several factors, including:
- Incorrectly formatting the request of the API.
- Understanding Binance's API documentation or user guide.
- Using an outdated or incompatible version of the Binance API customer library.
Solution: Add the compulsory parameter 'Type'
To solve this problem, you need to ensure that the Type parameter is included in your API request. Here is what you can do:
Option 1: Manually specify the type transaction
You can manually specify the type of transaction when requesting the API:
JavaScript
CONST PARAMS = {
'active': 'eth',
'Value': 100, // In Wei
'Type': 'Send' // or any other valid value (eg 'receive', 'Gaslimit')
};
Option 2: Update your Binance API customer library
Make sure you are using the latest version of Binance’s API customer library. You can check if there are updates on Binance’s official documentation.
Additional Tips
- Be aware of the size and structure of your API request. Make sure all parameters are formatted and included correctly.
- Make sure your application is running with enough permissions to make API requests.
- Keep an eye on any change in Binance’s API policies or documentation, which can affect your API call.
Conclusion
The problem you are finding when using the universal transfer call on binance requires attention to detail when creating your Ethereum API request. By adding a mandatory parameter type, you can solve this problem and successfully process transactions. Remember to verify that all the necessary parameters are included in your request and keep an eye on any change in Binance’s API policies or documentation.
Example of case use
To demonstrate how to add the Type parameter, let's create a simple javascript function that sends a transfer:
JavaScript
SENDTRANSFER FUNCTION () {
CONST PARAMS = {
'active': 'eth',
'Value': 100,
'to': '0x ...', // recipient's address
'Type': 'Send' // or any other value (for example, 'Receive')
};
Fetch (' {
Method: 'Post',
Headers: {
'Content-Type': 'Application/Json'
},
Body: Json.Stingify (Params)
})
.Then (Response => Response.Json ())
.Then (data => console.log (data))
.Catch (error => console.error (error));
}
By following these steps, you can ensure that your Ethereum API requests are formatted and performed properly in binance exchange.
