List Meraki Group Policies for all Organizations and their Networks. Uses Axios and async/await. Good pattern for traversing Meraki Dashboard API.

listGroupPolicies-allOrgs.js

/* Meraki Group Policy Tool

Traverse the Meraki Dashboard API to display IDs for Organizations, Networks and Group Policies

npm install axios json-bigint --save

Run:
$ API_KEY=2f30UseYourOwnAPIkEyd170f node listGroupPolicies-allOrgs.js

Basic Flow using async/await

- get orgs
- for each org, get network
- for each network, get policy
