Automatically revoke promotional entitlements

Hello Guys,

I have third party platform and every hour user data get from that platform using CRON JOB.

That data valid and if data valid then grant-a-promotional-entitlement api and give lifetime access after some time or next time same data get then automatically revoke-promotional-entitlements call. all data valid and already verified. 

package used Axios(https://www.npmjs.com/package/axios) for grant-a-promotional-entitlement

I will provide below sample code

import axios from "axios";
import config from "config";

const grantPromotionalEntitlements = async (app_user_id: string, cronName: string) => {
  const PayloadObject = {
    url:
      revenueBaseAPI +
      `subscribers/${app_user_id}/entitlements/${"All_Features"}/promotional`,
    method: "POST",
    headers: {
      "content-type": "application/json",
      Authorization: `Bearer ${SECRATE_KEY}`,
    },
    data: {
      duration: "lifetime",
    },
  } as any;


  const res = await axios(PayloadObject)
    .then((res) => {
      return res.data;
    })
    .catch((err) => {
      //console.log("grantPromotionalEntitlements", err);
      return null;
    });

  return res;
};

let me know if anything i missed this
