Print on demand
Three providers, three completely different sets of rules. Printify has a full API. Gelato has one with a hole in the middle of it. RedBubble has none at all, and forbids automating the form instead. SummaGrove works within what each one actually permits rather than pretending they are interchangeable.
Build the product, place the artwork, write the copy
Print-on-demand products and artwork. Products created here stay as drafts in Printify until you publish them there. The app's own description of the screen
Pick a blank, put the artwork where it goes, set the colours, sizes and prices, and write the listing. Nothing goes live on its own: what is created here sits as a draft in Printify until you publish it there yourself.
- Artwork placement you set and adjust, per product, against Printify's own render.
- An artwork check that reports the real numbers — pixel dimensions, the print size those give at 300 dpi, file size, how much of it is transparent.
- Colours, sizes and prices per variant, with a render for each colour where one exists.
- AI listing copy — title, description and tags, informed by what buyers actually search for.
- Apply a field to other products when the same change has to land on a whole range.
- It tells you why — a suggested change comes with the reasoning, not just the replacement text.
The artwork check advises and does not block. It will tell you that a file gives you eight inches at 300 dpi when the blank wants twelve; it will not silently upscale it or refuse the upload. File size is not evidence of resolution, and the report says what the pixels are rather than guessing from the megabytes.
Templates, and a fetch rather than an upload
Print on demand through Gelato, alongside Printify. The app's own description of the screen
Gelato's API creates products from templates you have already built in Gelato's own dashboard. It also has no endpoint for listing those templates, so each one is registered here once — open it in Gelato, copy the address, paste it in — and then stays available. Everything else follows from that: the catalogue, what a product costs to print, where it is in stock, and what Gelato will actually put on paper.
Gelato has no upload API — it fetches the file itself
Rather than accepting an upload, Gelato is given a web address and collects the print file on its own schedule: when the product is built, when an order is placed, and again for every reprint. So artwork stays on this server and stays reachable for as long as a product exists, instead of being deleted after the hand-off.
Each address is unguessable and is listed or indexed nowhere, but it needs no password — anyone holding the address can fetch that file. An address can be changed at any time.
Your Etsy orders are never forwarded to Gelato
Your shop is already connected to Etsy inside Gelato, so Gelato collects those orders itself. Nothing in SummaGrove forwards one, and nothing should: it would print and charge for every sale twice. The only orders raised here are reprints and one-offs, and both start as drafts.
Everything up to the upload, and then it stops
Designs staged for RedBubble, with the copy that goes with them. The app's own description of the screen
RedBubble publishes no upload API, and their agreement prohibits automating the form. So SummaGrove does the part it is allowed to do — stage the designs, draft the listing copy, keep it all together — and then hands you a text file holding the copy and where the artwork lives, for you to upload by hand.
- Nothing is sent to RedBubble — the app has no path to their site and is not trying to find one.
- Reuse artwork you already have from the Printify media library or the Gelato artwork you have uploaded.
- Listing copy drafted per design, and asked about before you navigate away from an unsaved edit.
- Sales recorded by hand, so the designs staged here can still be judged against what they earned.
The mistake that costs real money
Each provider pulls Etsy orders through its own connection, and neither can see the other. If the same Etsy listing has a product on both Printify and Gelato, a single sale can be printed and charged twice — and neither order appears in this app, because both were collected by the provider directly.
So SummaGrove looks for that overlap and says so, on both provider screens, naming the listings and linking to each one on Etsy. The fix is to keep one product per listing and remove the other at the provider that should not have it.
