# What are common reasons my products are not syncing to my website?

Products may fail to sync for several reasons. Common issues include:

* Incorrect or unauthorized store credentials, which prevent Stock Sync from accessing product data.
* Missing required columns in your feed file, such as TITLE or PRODUCT NAME, causing products to be skipped.
* Using the wrong file format (e.g., XML instead of JSON) for your feed setup.
* Supplier-side filters that block product data from being returned.
* Shopify variant limits being exceeded.
* Metafield validation mismatches where values in the feed do not match the metafield definition choices.
* Image field mapping pointing to a nested image group instead of direct image URLs, which can cause the import to fail halfway.
* Feed processes being cancelled automatically when more than 80% of products in the feed show zero quantity, depending on threshold settings.

Reviewing these items often resolves most syncing issues quickly.
