node-aws-acm/ACMDeleter.js

A lightweight npm package to interact with AWS Certificate Manager (ACM) using Node.js.

const AWS = require("aws-sdk");
const dotenv = require("dotenv");

  // Input can be either a domain name or a certificate ARN
  // Calls the provided callback function with an error or data object

    let params = {};

    // If input is an ARN, use it as the CertificateArn parameter in deleteCertificate API
