Every resource method returns a promise.

waInstance.sendTextMessage(number, message)
  .then(response => {
    // handle success
  })
  .catch(error => {
    // handle error
  });

If you want to use callbacks instead of promises, every resource method will accept a callback function as a last parameter. The callback functions will behave as Error First Callbacks

waInstance.sendTextMessage(number, message),
  (error, response) => {
    if (error) {
      // handle error
    } else {
      // handle success
    }
  }
);

Example - Node.js

// number must start with the country's dialing code

const WAEasyAPI = require('waeasyapi');

const waInstance = new WAEasyAPI({
  acc_id: 'YOUR_ACC_ID',
  acc_secret: 'YOUR_ACC_SECRET',
});

waInstance.sendTextMessage('19876543210', 'Hello WA Easy API!')
  .then(response => {
    // handle success
  })
  .catch(error => {
    // handle error
  });

Example - Typescript or ESNext

// number must start with the country's dialing code

import WAEasyAPI from 'waeasyapi';

const waInstance = new WAEasyAPI({
  acc_id: 'YOUR_ACC_ID',
  acc_secret: 'YOUR_ACC_SECRET',
});

waInstance.sendTextMessage('19876543210', 'Hello WA Easy API!'),
  (error, response) => {
    if (error) {
      // handle error
    } else {
      // handle success
    }
  }
);
