I am beginner WordPress Developer. I need experts help. I am currently working on WooCommerce Store where my client wants to automate its store by fetching and showing digital products on their store by a Supplier like (G2A.com). I try many solutions but no one was working that’s the problem any experts of WordPress can help me!

When i do a put request using the WP API to the following endpoint i get an error (but only sometimes) and i can’t figure out what the issue is. Could it be a race-condition, caching issue (we’re using w3 cache) or something else?
