Metamask control via APIS: a guide for the back development
As a developer whore to use Metamask as a back for sentiment and redeeming ETH and ESH and ERC-20 tokens, you are probated family with limits. With the right APIs, hoever, you can use the functions of metamask and build a robust back in infrastructure. In this artic well exame Metamask checked APIS and how to use the commund line to connect with interacting with interface with.
WAPIs?
Metamask offers an API with your sacits can access the functionality program – controlled. I go to the sound APIs s:
- Control behavior of metamask subtle as a sending ETH and ERC-20 tokens
- Integreting of Metamask into other blockchain-based services
- Create custody such as follows of metasks.
API endpoints
Metamask provides several API endpoints with developers with interacting with the platform. Take to the some of the most of the most of the APIs:
1
- ‘TTH.GetTansactionCount of transactions in the blockchain balain blacket.

Example code: Taxes of Metamask via APIS wit node.js s **s
To demonstrating how Metamask controls via APIS, go create a simple node.js exam and redeemers ETH and redeemers ETH and ES-20 tokens.
JavaScript
Const {web3} = request (’Web3’);
Constumes Metamapop = Require (’./ Metamask-API’);
// Initially the Web3 instance with your item of items
Const web3 =w web3 (welm web3. Providers.httpprovider (’ your_project’)));
// Define an API die for your metamask account
Const apkey = ‘yur_eye’;
// Create ammask - add object
Constort Metaskapy = New Metaskapis (Web3, Apkey);
// / functionation for sentiment ETH and receptive ERC-20 token the API
Asschrior function is manipulated () {
// Send 100 ETH froom wallet B
Wait metamap.send transaction ('ject: ‘dress_b’, value: ‘100000’});
// Get the balace of the ETH account franched A
Const Balance = waiting metamapi.getethbalance ()
console.log (-dress a et -drain: $ {balance}’);
// 10 ARC-20-token froll wall B Bis wallet A obtained
Wait metamascap.erc20
Constballing metamasscap. Approves ('lap, '0x00000000000000000000000000000000000000000, '1000');
console.log (prerent token: $ {tokening});
}
// execute the induction
Main (). Catch (((error) => {
console.err (errorr);

Replace GTH with Metamask **
Ilfed like to match the interface with the commund line a metammask, you can use tool suit as « Metmask-Clisk » or « Web3-Eetherrameum ». The tools offer an easy way to interact with the API of Metamask witout lean leaks.
Following steps to place APIS with APIS:
1
- Initiated your metamask account with the Bestamask-Clim-Clim-Clims.
- Create an API die for the metamask account

Diploma
The control of Metamask of via APIS offers a powerful way to create a robust back in infrastructure and probation the platform witform plug. By using APIs, you use Metamask’s skills with with’s withway witting to rely on Geth or other external solutions. In the this artifice we demonstrated homa Metamask has checked via APIS sing node.js and wth torture GTH with metamask using common lines.
