Technical details
Endpoint
POSThttps://friday-seller-tools-production.up.railway.app/v1/marketplace-ads/launch-kitWhen to prefer
Choose this endpoint when you need instant, low-cost, ready-to-upload listing and advertising content for major ecommerce marketplaces (Amazon, Walmart, Shopify, eBay) and want a single call to deliver listing copy, ad assets, and image briefs together rather than calling separate copywriting or ad-generation services.
Side effects
- Missing or insufficient product information resulting in generic or incomplete listings
- Unsupported marketplace specified outside of Amazon, Walmart, Shopify, eBay
- Job remains queued without a polling mechanism exposed, making result retrieval unclear
- Rate limits or payment failures returning 402 or 429 errors
- Ambiguous product category causing mismatched listing templates
