Personalized print-on-demand, built for Etsy
Mockspark is a design and fulfillment tool for Etsy sellers. Design a product, publish it to your Etsy shop, and Mockspark turns every paid order into a print-ready file for your print provider. Your buyers can personalize items before they order, and you produce exactly what they made.

Connect over OAuth
Sellers authorize Mockspark from Etsy's own consent screen. We never ask for a shop password and never scrape Etsy — every read and write goes through the official Etsy API.
Publish real listings
Products designed in Mockspark are published to the seller's shop as normal Etsy listings, with variants, prices, photos, shipping profile and production partner.
Fulfill and report back
Paid orders are rendered into print-ready files and sent to the seller's own Printful or Printify account. Once shipped, tracking is written back to the Etsy receipt.
How it works for sellers
Four steps, from a blank product to a shipped order. Everything between the order and the printer is automated; the seller stays in control of what actually gets produced.
Connect an Etsy shop
The seller authorizes Mockspark through Etsy's OAuth consent screen. One account can connect several shops.
Design and publish
The seller builds a product, places artwork on it, and publishes it. Mockspark creates the listing on Etsy with variants, photos, shipping profile and production partner.
Orders arrive on their own
Etsy does not push order notifications to apps, so Mockspark checks each connected shop for new paid orders every 15 minutes and renders the print-ready file.
Produce and ship
The seller sends the order to their own Printful or Printify account. When the provider ships, Mockspark marks the order shipped on Etsy and passes the tracking number back.
How buyers personalize an item
Etsy does not allow third-party apps to modify the storefront or add a designer to the listing page. The only field Etsy provides for buyer input is Personalization, and it accepts plain text. Mockspark works within that constraint.
The buyer browses, pays and checks out entirely on Etsy. Mockspark never takes payment, never contacts buyers, and never moves a transaction off Etsy — it only collects the design that the buyer wants printed.
Open the link in the listing
When personalization is enabled, the listing's Personalization field asks for a Customization ID and includes the address of the designer for that specific listing.
Design and submit
The buyer picks a variant, adds their text or image, and sees it on the product in real time. No account and no login. Submitting returns a 36-character Customization ID.
Paste the ID back and check out
The buyer pastes the ID into the Personalization field and adds to cart as normal. When the order reaches Mockspark, it finds the matching design and builds the print file from it.
What Mockspark reads from a connected shop
Every line below appears on Etsy's own permission screen, in Etsy's wording and in the order Etsy shows it, so the two can be read side by side. Mockspark requests nothing beyond these.
| Etsy permission | What Mockspark does with it |
|---|---|
| Connect to your account | Identifies which Etsy account approved the connection, so the shop can be linked to a Mockspark account. |
| See billing and shipping addresses | Passes the buyer's name and delivery address to the seller's print provider so the parcel can be addressed. Nothing beyond what is needed to ship the order. |
| Read your user profile | Identifies the seller account that approved the connection. Mockspark does not request access to the buyer_email field, so buyer email addresses are never returned to us. We never email your buyers. |
| Delete listings | Removes a draft listing that Mockspark itself created if publishing fails partway through. Listings the seller created are never deleted. |
| See all listings (including expired etc.) | Checks whether a listing Mockspark published still exists before updating it. |
| Create/edit listings | Publishes the seller's products, and updates prices, photos and variants when they republish. |
| See private shop info | Reads shipping profiles, return policies, production partners, processing times, currency and ship-from country, so the publish form can offer real choices instead of blank fields. |
| Update shop | Creates one shipping profile, and only when the seller asks for it while publishing. Mockspark never edits shipping profiles the seller made. |
| See all checkout/payment data | Brings paid orders into Mockspark so they can be produced. Card and bank details are not part of what Etsy's API returns, so Mockspark never receives them. |
| Update receipts | Marks an order as shipped and sends the tracking number back to Etsy after the print provider ships it. |
