activate_integration_pixel
Install the Shopify storefront tracking pixel on the connected store, or repoint an existing one at this account. This is what turns on product views, cart activity, and browse abandonment - the data every browse-abandonment and cart-recovery sequence depends on. Idempotent: an already-live pixel returns changed: false. Events start flowing on the next storefront visit and nothing is backfilled for the period the pixel was off, so run it before, not after, building the sequence. If the store granted an older permission set, this fails with a message naming the reconnect step rather than silently doing nothing. Shopify only.
