If you're using Shopify's New Customer Accounts (NCA) and have custom blocks in your Tapcart app that depend on customer metafields (like membership tiers, loyalty status, or club pricing), there's an additional configuration step required in Shopify to make those metafields accessible.
Why This Matters
Tapcart's existing metafields setup guide walks through enabling Storefront API access for product, collection, and order metafields. However, customer metafields work differently. They're tied to the authenticated customer session and require a separate access setting to expose them to the app.
When NCA is enabled, Tapcart uses Shopify's Customer Account API to fetch the logged-in customer's data. If your customer metafields don't have Customer Account API access enabled, that data won't pull through and any custom blocks relying on it (membership checks, gated content, personalized pricing, etc.) will not work as expected.
How to Enable Customer Account API Access for Customer Metafields
In your Shopify Admin, go to Settings and select Metafields and metaobjects
Choose Customers
Select the metafield definition you want to use in app
Scroll down to the Access section
Under Customer Account API access, select Read
Save the metafield definition
Repeat for any other customer metafields used in your app
Note: Read access is sufficient for Tapcart to fetch and use the metafield value in custom blocks. Write access is not required.
Common Symptom
If logged-in customers aren't being recognized by a custom block and you've recently enabled NCA, missing Customer Account API access on your customer metafields is the most likely cause.
