Backfill Shopify product photos with Dreem.ai and Slack

Description

Quick overview
New products get attention; the back catalog doesn't. This workflow sweeps your Shopify catalog, finds every product that still has just one photo, and generates the missing studio product shots with Dreem.ai - one product at a time, so a 300-product store fixes itself while you do something else.

How it works
Run it manually for a one-off sweep, or swap the trigger for a Schedule to run unattended.
Fetches all products from Shopify and keeps only products with exactly one image and without the dreem-shots-added tag.
Processes matching products one at a time and sends the product’s existing image to Dreem.ai to generate the selected studio shot types.
Waits for Dreem.ai to call back via a webhook (up to 20 minutes) and checks whether the render completes successfully.
If completed, updates the Shopify product by appending the generated images and adding the dreem-shots-added tag to prevent reprocessing.
If the render does not complete in time, posts a “skipped” message to Slack and continues to the next product, then posts an “all done” message when the batch finishes.

Setup
Add a Shopify Admin API access token credential with read_products and write_products scopes.
Install the Dreem.ai community node (n8n-nodes-dreem) and add your Dreem API key credential.
Add a Slack OAuth2 credential and choose the channel for the “Skipped” and “All Done” messages.
(Optional) Enable the Slack approval steps and the back-shot generation branch, then update the Shopify image-count filter to include products with both front and back source images.

Requirements
Dreem account + API key, Shopify store with Admin API access, Slack

Customization
Change shot codes, widen the image filter, exclude products by tagging them dreem-shots-added yourself, or add a Schedule trigger.
