If you only have little experience with custom development, I highly recommend you stick with the official plugin, Google for WooCommerce (formerly Google Listings & Ads). What you’re proposing, building your own API integration, is a much larger stack than you think. You’ll just create ongoing work for yourself maintaining authentication, version updates, API schema changes, error handling, etc., which the WooCommerce dev team is already doing for you. Also, building your own integration won’t fix the issue you’re complaining about. The 24-hour delay isn’t caused by the plugin - it’s caused by Google Merchant Center itself. Google controls when products get reviewed, indexed, and published. Whether you use a feed, the official plugin, or a custom API script, you’re still subject to Google’s processing times. Short version You’re not going to bypass Google’s own rules or timelines, no matter how you push the data. Answer from CodingDragons on reddit.com

Overview | Content API for Shopping | Google for Developers
Although merchants have the ability to load products using a file called a Primary Feed, there are several advantages to creating, updating, and deleting products using the Content API, including faster response time and the ability to update multiple products in real time, without the need to manage multiple supplemental feeds.

r/woocommerce on Reddit: How can I go about integrating the google API to sync my products to Google Merchant Center without using a plugin?
April 28, 2025 -
I am currently using a product feed via a plugin, but I dont like the delay of updates(every 24 hours) and also dont like the google for woocommerce plugin.
I have little experience, in terms of wordpress custom development, but not afraid of getting deep in the sauce.
General guidance is appreciated.

API about fetching products feeds
However, when I click on "Feeds" page on Merchant Center, the "STATUS" is still showing "This feed has never been uploaded.", but in "SETTINGS" and "SCHEDULE", both are correctly showing what I have input on API including fetch time, time zone, fetch url, etc.. When I click on "FETCH NOW", the "STATUS" page will show items has been processed. This is what I need, except the action to click on button "FETCH NOW". Below is my code for calling API to insert product feed:
