Is this normal? How do I enable it?
Topic summary
A user discovered their additional scripts section is disabled in Shopify checkout settings.
Root Cause:
Shopify’s checkout extensibility feature has been activated, which disables the traditional additional scripts functionality.
Available Solutions:
- Temporary revert: Navigate to Settings → Checkout and switch back to the old checkout system
- Long-term migration: Implement scripts differently using official/custom apps, customer events, or pixels for analytics
Specific Use Case:
The user needs to maintain a Cryptomus payment integration script that was previously in additional scripts.
Community Sentiment:
Some users view this change as disruptive, encouraging affected merchants to file support complaints to pressure Shopify for better solutions or communication.
Resources:
Shopify’s official documentation on checkout extensibility and upgrade guides are available for merchants needing to migrate their custom code.
You probably activated checkout extensibility. Read about it here:

You can revert it, but in the future, you have to activate it anyway.
Shopify broke everyone’s additional scripts with the checkout extensibility. It is very careless and destructive on their part. After talking to chat for an hour, they did nothing but blow me off. File a complaint with their support. The more people that tell them what they are doing is wrong, the more they will be pressured to fix it.
So what should I do?
You can temporarily revert it to the old one in the settings (settings → checkout), or implement it differently, using official/custom apps or customer events/pixel (for analytic logic). What kind of code is it? There are different possibilities for different logics.

It is the code that connects cryptomus.
