# Product Module

## Docs

- [Products](https://tieback.io/docs/product-module/products.md): Browse, search, and edit your product catalogue in tieback, with identity fields, DPP attribute sections, mint readiness, and full identifier history.
- [Custom Fields](https://tieback.io/docs/product-module/custom-fields.md): Extend your product data model with brand-specific custom fields that sit alongside the standard DPP schema across products, mints, and passports.
- [Global Search](https://tieback.io/docs/product-module/global-search.md): Find any product, token, batch, or export across your workspace with Spotlight Search, including GS1 Digital Link and resolver URL paste lookup.
- [Product Identifiers in tieback](https://tieback.io/docs/product-module/identifiers.md): How tieback models SKU, GTIN, EAN, and UPC identifiers, including validation, active and retired status, audit history, and resolver interoperability.
- [Product Import](https://tieback.io/docs/product-module/product-import.md): Import products into tieback from CSV, map source columns to fields, validate rows before committing, and review per-row insert, update, and error results.
- [Bulk Editing](https://tieback.io/docs/product-module/bulk-editing.md): Edit attribute values across many products at once from the Product Library, using the column picker, inline cell editing, and bulk apply actions.
- [Bulk Updates](https://tieback.io/docs/product-module/bulk-updates.md): How tieback processes large product updates as background jobs, with queued and processing states, per-item outcomes, retries, and progress tracking.
- [Resolver and GS1 Digital Link](https://tieback.io/docs/product-module/resolver-gs-1-digital-link.md): How tieback resolves GS1 Digital Link identifiers into a Digital Product Passport, so every printed QR code keeps working for the life of the product.
- [GS1 Digital Link Contract](https://tieback.io/docs/product-module/gs-1-digital-link-contract.md): The GS1 Digital Link URL contract used by tieback resolvers, covering supported application identifiers, path order, normalisation and redirect behaviour.
