To ensure accurate tracking and a seamless setup, it's essential to use the same content ID format in your setup as the one in your Facebook catalog. The Content ID helps Facebook match your products with ad events, improving tracking accuracy and campaign performance.
In Analyzify, you should use the same format as in your catalog to avoid mismatches. Follow these steps to find content ID in Facebook / Meta:

Verify Your Content ID Format
Now that you've found your content ID in Facebook, it's time to check Shopify's side by debugging your live website. You can verify your ID format in two ways:
- Through Shopify Admin
- Through Developer Tools
Through Shopify Admin
To verify your content ID in Shopify, go to the Products section and find the same product you checked in your Facebook Business Manager. Then, click on it, and you can compare all the IDs associated with that product.

Through Developer Tools
