"content": "## Backfill studio product photos for single-image Shopify products with Dreem.ai\n\n### How it works\n\nThis workflow manually backfills studio-style product photos for Shopify products that currently have only a single image. It fetches products, filters for missing shots, loops through each item, generates front and back renders with Dreem.ai, asks for Slack approval on the front shot, and publishes approved/completed images back to Shopify. Slack is also used to notify when items are skipped and when the full run is complete.\n\n### Setup steps\n\n- Configure Shopify credentials and confirm the product query returns the catalog segment you want to backfill.\n- Configure Dreem.ai credentials and set the front/back render prompts or product-image inputs in the Dreem nodes.\n- Configure Slack credentials, the review channel, approval interaction settings, and completion/skipped notification destinations.\n- Review the filter logic in \u201cMissing Product Shots?\u201d so it matches your definition of single-image or missing-photo products.\n- Adjust wait durations and completion checks to match typical Dreem.ai render times and response fields.\n\n### Customization\n\nYou can change the product filter, batch size, Slack approval wording, Dreem.ai render prompts, and whether back shots require a separate approval step before publishing."
