Integration of ChitChats delivery provider's API into my Wix ecomm site

I’m having trouble with

The custom Chit Chats API integration isn’t mapping correctly to the Wix dashboard backend. The code runs without syntax errors, but the native “Carrier Rates” option is entirely missing from the shipping calculation dropdown menu. At checkout, customers receive a false error message stating, “the item cannot be shipped to your region.”

Working in

Dev Mode (Velo) / Wix E-commerce Shipping Rates Service Plugin (SPI)

What I’m trying to do

I want to fetch dynamic, live delivery rates from Chit Chats via their API and display them seamlessly to customers on the Wix checkout page based on their cart weight and destination.

What I’ve tried so far

  • Successfully added the custom API fetch and integration code without console or runtime errors.

  • Verified that the target shipping regions are active and properly configured inside the native Wix Settings.

I was able to reproduce this bug, there is total silence in the logs, even for simple console logs

it something internal to wix, its not calling the plugin at all

this issue is similar to Critical Synchronization Issue: Custom Shipping App Returns Rates Successfully, but Wix Checkout Fails to Render Them (ASAP Delivery Orchestrator V1.10.0)

which is also unresolved
