Create Printify products from designs with AI

You have twenty new designs, and each one needs the same product built again in the Printify Product Creator: blueprint, print provider, colors, sizes, price, title and tags.

Cotlet does it in your own Printify account with upload_image, list_blueprints, get_blueprint_variants and create_product, called by your AI agent, an n8n workflow or a script.

Can Printify do this on its own?

Printify has no bulk creation inside the dashboard that builds products from a list of designs (checked 17 Oct 2026). The public API v1 creates products and uploads images, but it needs a token and your own code: you choose the blueprint, the print provider and every variant ID yourself. There is no official MCP server.

How you do it in Printify today

  1. In the Printify dashboard you open the Product Creator and pick a product from the catalog.
  2. You upload the design, place it on the print area and choose the print provider.
  3. You enable the colors and sizes you want to sell and set a retail price for them.
  4. You write the title, description and tags, then save the product under My Products.
  5. The routine repeats for every design and every product type, so a new collection means the same clicks many times over.

How to create Printify products from designs with AI

Prompt

Upload the three PNG files from this folder URL to my Printify media library, then create a draft unisex t-shirt for each one in sizes S to XL, priced at $24.99. Do not publish anything.
  1. 01

    Upload each design once

    upload_image sends every file by URL to your Media Library. The agent keeps the returned image ID and reuses it for every product type made from that design.

  2. 02

    Pick blueprint and provider

    list_blueprints finds the product type you named, for example a unisex t-shirt. get_blueprint_variants then returns the variants one print provider offers, so the agent only uses sizes and colors that are in stock.

  3. 03

    Build the variant list

    The agent keeps the sizes you asked for, S to XL, and sets one price on all of them. Prices go out as integers in cents, so $24.99 becomes 2499.

  4. 04

    Create the draft

    create_product sends title, description, tags, variants and the print area with the image. Nothing reaches your store: the product stays in My Products until a separate publish call.

  5. 05

    Report what was built

    The agent lists each new product with its ID, the variants enabled and the price, so you check the batch before publishing any of it.

What you get back

Example data

Uploaded 3 designs to the Media Library
Created 3 draft products, 5 variants each (S to XL), $24.99:

- "Coffee First Tee" (prod 6641ab13)
- "Plant Parent Tee" (prod 6641ab14)
Published: 0

Other ways to ask

  • Make the same design as a tee, a hoodie and a mug, each at its own price, and keep them as drafts.
  • Create products for every new image in my Media Library that has no product yet.
  • Copy the title, tags and prices of my "Night Owl Club Tee" onto these two new designs.

What Printify allows, and what to know first

  • Printify requires title, description, variants and print areas to create a product, and blueprint_id and print_provider_id cannot change after creation.
  • A variant needs only its id and price at creation, and prices are integers in cents.
  • Printify accepts an image upload by URL or as base64 content, and recommends the URL for files over 5 MB.
  • The Printify API allows 100 catalog requests per minute per account, on top of the global limit of 600 requests per minute.
  • A new product is not on your sales channel until it is published, so a mistake in a draft reaches no customer.

upload_image and create_product change only your own Printify data and reach no one else, so they run without asking first.
