Edit Mailchimp API to also include Tag in Email Submissions

Currently, I have a cloud function in which I also want to add a tag that I define to email submissions. My current function minus the api keys is the below. I wish to edit this to include tags on submssions: A stock overflow submission about this topic: [login to view URL] CURRENT FUNCTION BELOW: const express = require("express"); const app = express(); const axios = require("axios"); [login to view URL]([login to view URL]()); [login to view URL](function (_, res, next) { [login to view URL]("Access-Control-Allow-Origin", "*"); [login to view URL]("Access-Control-Allow-Methods", "GET,PUT,POST,DELETE,OPTIONS"); [login to view URL]( "Access-Control-Allow-Headers", "Content-Type, Authorization, Content-Length, X-Requested-With" ); next(); }); [login to view URL]("/subscribe", async (req, res) => { try { const email = [login to view URL]; const subscriber = { members: [ { email_address: email, status: "subscribed", }, ], }; await [login to view URL]( "[login to view URL]", subscriber, { headers: { Authorization: "auth MYAUTHEYHERE", }, } ); [login to view URL]({ msg: "success" }); } catch (err) { [login to view URL](err); } }); const PORT = [login to view URL] || 5000; [login to view URL](PORT, () => [login to view URL](`server is running on port ${PORT}`));
