Generate Minecraft Block Textures with MapMC via Webhook

Generate Minecraft block texture PNGs using MapMC AI—triggered by an n8n form or Webhook

This n8n automation takes a Minecraft block texture prompt, sends it to the MapMC AI Textures API, waits for the async job to finish, and returns a JSON response with generated PNG asset URLs and job metadata—fully webhook-ready.

What this workflow does

• Receives a texture request from an n8n form submission or an inbound webhook call.
• Normalizes the input into a consistent payload (including prompt, resolution, and outputCount) and creates an idempotency key for the run.
• Creates an async MapMC job by sending a POST request to the MapMC API to generate a Minecraft block asset.
• Polls for completion: waits 10 seconds, then repeatedly checks the MapMC job status URL until it completes.
• Returns results on success by formatting job details and the asset list into a JSON payload containing the generated PNG URLs.
• Fails fast on terminal errors: if the job ends in a terminal failure state (e.g., failed, refunded, or deleted), the workflow stops and returns an error message.

Use cases

• Build an AI texture generator page where users submit a prompt and instantly receive Minecraft-ready textures as PNG URLs.
• Automate texture requests from a SaaS backend—send prompt + resolution + output count via webhook and store the returned asset URLs.
• Generate consistent block variations for modpacks by rerunning prompts with different resolutions or output counts.
