Issue to accessing backend

My website on Netlify: is deployed by a Fiverr user: This user has the backend for my website and I can’t get a hold of him. Is there a way to gain access to my website’s backend files without having to access his account?

The short answer: No

The long answer: Withdrawing previous answer. See short answer above.

Would you kindly explain how if there is a way Sir?

Have withdrawn part of my previous answer.

You’ve made a terrible business decision. I hope you’ve learned a valuable lesson.

We have no way of giving you access to the site with proof of ownership. You will need the creator to give you access.

Even if I own the Netlify account? Sorry if it’s a stupid question Sir

If you manage the Netlify account you can download a deployed site. But that doesn’t the source files.

Is the backend even hosted on Netlify?
