Generate Printful mockups for new designs

You finished a design and need product photos for the listing. Each template means a trip through the mockup download page, and a new collection can have a dozen templates. The styles you pick for one product are easy to forget on the next.

Cotlet does it in your own Printful account with list_product_templates and generate_mockups, called by your AI agent, an n8n workflow or a script.

Can Printful do this on its own?

Printful has a Mockup Generator in the Dashboard and in the API, with a limit of 10 requests per 60 seconds for established stores and 2 for new ones (checked 17 Oct 2026). The API needs a task, then polling for the result. Neither the Dashboard nor the API runs a batch of templates from one instruction.

How you do it in Printful today

  1. You open Product templates in the Dashboard, or My products and then Product templates.
  2. You hover over the template and choose Download mockups from the menu.
  3. On the mockup page you select the mockup styles.
  4. You click Generate files, then Download mockups.
  5. You repeat the steps for every template and every product, and pick the same styles again each time.

How to generate Printful mockups for new designs

Prompt

Take my product template "Autumn tote" and generate mockups in all available styles. Give me the download links.
  1. 01

    Find the template

    list_product_templates returns your templates with ID and name. The agent matches the name you gave to one template and asks if two names are close.

  2. 02

    Generate

    generate_mockups starts generation for the template and the styles you asked for, then waits for Printful to finish the files before it answers.

  3. 03

    Return the links

    The agent lists each mockup with its style and its download link, and flags a style that Printful did not produce. It reports a template that has no design on it instead of returning an empty set. You download the files from the links, since mockup URLs do not last.

What you get back

Example data

Template: Autumn tote (ID 7723)
Mockups generated: 4
- Front, flat
- Front, on model
- Back, flat
- Lifestyle
Download links attached, one per image.

Other ways to ask

  • Generate only the flat mockups for every template that has "tote" in its name.
  • Generate mockups for my 5 newest templates and report which ones failed.

What Printful allows, and what to know first

  • In the Dashboard you reach mockups through Product templates or through a published product.
  • Printful has a Mockup Library on each product page under View all mockups.
  • The API caps the Mockup Generator at 10 requests per 60 seconds for established stores and 2 for new stores.
  • Generated mockup URLs are temporary, so download them when the agent returns them.

generate_mockups changes only your own Printful data and reach no one else, so it runs without asking first.
