Generate GTIN-14 test values for product feeds with Ecomwith

Description

Quick overview Generate format-valid GTIN-14 test values and map them to SKU prefixes for ecommerce feed QA. Learn more: https://ecomwith.com/tools/gtin How it works Receives quantity and SKU prefix from the GTIN Form. Logs the raw form payload to the n8n run-log Data Table for traceability. Bounds quantity and trims the SKU prefix before creating an idempotent request. Calls the Ecomwith GTIN Generator and formats the returned GTIN-14 values. Maps every generated value to its source SKU prefix for product-feed QA. Returns quota and rate-limit metadata, or a structured error object with troubleshooting links. Setup Create an Ecomwith API key with scope tools:gtin:generate at https://ecomwith.com/settings/apikeys. Store it in an n8n HTTP Header Auth credential named Ecomwith API with header X-API-Key. Confirm the credential is selected by the HTTP Request node and the n8n-creator-run-log Data Table exists. Submit the generated form URL with a small quantity and keep the workflow inactive until the credential and smoke test are verified. Requirements An n8n HTTP Header Auth credential named Ecomwith API; scope tools:gtin:generate; access to the n8n-creator-run-log Data Table; quantity 1–100 and a SKU prefix for each test request. Customization Adjust the form fields, quantity bounds, SKU prefix convention, or result columns for a different product-feed QA process. Keep the format-validation boundary visible in the guide note. Additional info Values generated by this workflow are for format QA and are not official GS1 assignments. Review https://ecomwith.com/tools/gtin before using the output.
