*URGENT* fetch car data/images from autoscout api(graphQL) into wordpress website

I have an ongoing project
previous developer/freelancer had to automate car data from
autoscout api (graphQL) and import them into the website (wordpress/ vehica theme)

There was an issue with fetching car images/ downloading and showing them on the website.
freelancer made me upgrade the server because there was a server resource problem.
Problem still exists. with images not showing on the website.

Code for fetching the data/ api connection already exist. Now I am searching for someone that can solve this problem.

if car is sold on autoscout and removed, it also has to be updated on the website and change the field from
"te koop" to "verkocht" ( for sale -> sold )

daily there has to happen a pull to see if new cars are uploaded
OR automatically detect when there are cars uploaded to autoscout
OR visit link/ press button to fetch newly added cars to the website

website is hosted at Godaddy
