This means that column headers, required fields, and accepted values may vary across retailers, or even between product categories. To ensure your proposal is accepted and processed correctly: * Always use the template provided by the merchant. Don't reuse templates from other merchants or modify the column headers. * Don't rename, remove, or reorder columns. * Fill out all required fields as defined by the merchant. These may not be visibly marked in the file, so refer to any instructions or notes included in the template. * Use consistent formatting for values such as prices, dates, and SKUs. Merchants may validate inputs against expected formats. * Contact your merchant partner if you're unsure how to fill out a field, or if you're working with a template that lacks formatting guidance. If your merchant partner has defined custom formatting for product attributes, you may need to select a transformer during import. This ensures your product data is automatically adjusted to meet the merchant’s formatting or mapping requirements.

If you're unsure whether a transformer is needed or how to configure one, please file a ticket with fabric Support. ## Procedure 1. From the top menu in Dropship, click **Products**.
