How to: GET Data from 2 APIs, compare, POST bool - node.js

Question

I'm working on a project that requires me to:
GET IDs from API1, push the IDs into an array, then map over those IDs, using them for a second GET request, where IDs are used as params for API2 GET request, populates an array with IDs or N for "Not existing" -- this array is then called in:
A POST request. This post maps over the returned array from the GET request. IF the item is not "N", it POSTS to API1 with checked: true. IF the item is "N", it emails us telling us API2 is missing this project.
I want this system to automatically do a GET and POST every 2 hours, so I'm using setInterval (not sure this is the best idea). EDIT: Cron job would be a better solution.
I'm working with NodeJS, Express, Request-Promise, Async / Await.
Here is some of my pseudo code so far:
// Dependencies
const express = require('express');
const axios = require('axios');
const mailgun = require('mailgun-js')({ apiKey, domain });
// Static
const app = express();
app.get('/', (req, res, next) => {
// Replace setInterval with Cron job in deployment
// Get All Ids
const orders = await getGCloud();
// Check if IDs exist in other API
const validations = await getProjectManagementSystem(orders);
// If they exist, POST update to check, else, mailer
validations.map(id => {
if (id !== 'n') {
postGCloud(id);
} else {
mailer(id);
}
});
}
// Method gets all IDs
const getGCloud = async () => {
try {
let orders = [];
const response = await axios.get('gCloudURL');
for (let key in response) {
orders.push(response.key);
}
return orders;
} catch (error) {
console.log('Error: ', error);
}
}
// Method does a GET requst for each ID
const getProjectManagementSystem = async orders => {
try {
let idArr = [];
orders.map(id => {
let response = await axios.get(`projectManagementSystemURL/${id}`);
response === '404' ? idArr.push('n') : idArr.push(response)
})
return idArr;
} catch (error) {
console.log('Error: ', error);
}
}
const postGCloud = id => {
axios.post('/gcloudURL', {
id,
checked: true
})
.then(res => console.log(res))
.catch(err => console.log(err))
}
const mailer = id => {
const data = {
from: 'TESTER <test#test.com>',
to: 'customerSuppoer#test.com',
subject: `Missing Order: ${id}`,
text: `Our Project Management System is missing ${id}. Please contact client.`
}
mailgun.messages().send(data, (err, body) => {
if (err) {
console.log('Error: ', err)
} else {
console.log('Body: ', body);
}
});
}
app.listen(6000, () => console.log('LISTENING ON 6000'));
The TL;DR: Need to do a GET request to API 1, then another GET request to API 2 following it (using IDs from API 1 as params), then send data from second GET to a POST request that then either updates API 1's data or emails Customer support. This is an automatic system that runs every two hours.
Main Questions:
1. Is it okay to have a setInterval in a get req?
2. Can I have a GET request automatically call a POST request?
3. If so, how can I pass GET request data onto a POST request?

Answer 1

To make it work for both of your calls one post and one get you have to do an Ajax call to get post processed information in another method.
I hope this works.
