thirds.ai for Zapier
A Zapier PDF generator for files that look designer-made.
A Zap can pass an order along, but someone still has to make the invoice look good. Add one thirds.ai step, and each run fills a design you saved, so the file comes back finished in your logo and colours.
Free to start, and no card needed.

How do I create a PDF in Zapier?
Three steps, and from then on every Zap in your account can make PDFs and images from the designs you save.
Zapier
Add the thirds.ai app
thirds.ai joins Zapier by invite, so it isn't in the app search. Accept the invite from this button, and Make a PDF and Make an Image show up when you add a step.
Paste in an API key
Click Create a key on thirds.ai and copy it. Zapier asks for this key, a kind of password, the first time you add a thirds.ai step.
Get an API keyPick your design in the Zap
Add a thirds.ai step, pick the design you saved, and fill each blank in it from an earlier step, like the customer's name or the total.
Read the setup guide
Each of these can leave your Zap ready to send.

A real design beats a Google Docs template.
A design you saved on thirds.ai comes out of every Zap as polished as the template you picked, and the hundredth certificate looks as good as the first. If you've tried a Google Docs template in a Zap, you know that PDF looks like a form letter with a logo pasted on top.
- Your fonts, colours, and logo come out right on every page, with nothing to check before it goes out.
- Change the design on thirds.ai and save it, and every Zap sends the new version from then on.
Images from a Zap
A Zapier image generator for posts and coupons in your brand.
When a product goes live in your shop, a Zap can make its post too, and a sale date in your spreadsheet can become a coupon. An AI picture generator gives you something a little different each try, and someone has to check it. A design you saved comes out the same every time, so the picture can go straight to your feed.
- Every new product gets its post without anyone opening a design tool.
- Pick PNG, JPEG, or WebP, at the exact size your post needs.

Questions people ask before they add thirds.ai to a Zap
Add thirds.ai to ZapierHow do I add thirds.ai to Zapier?
Click Add thirds.ai to Zapier at the top of this page and accept the invite. The app is invite-only, so it won't show in Zapier's app search until you accept it. Then get an API key from your thirds.ai account, add a thirds.ai step to a Zap, and paste the key in when Zapier asks for it. Set up the Zapier app step by step.
Which apps can start the Zap?
Any app Zapier connects. A new form reply, a new row in Google Sheets, or a paid order in your shop can all start it. After the thirds.ai step, send the file anywhere Zapier reaches, like Gmail or Google Drive.
What does a PDF or image from Zapier cost?
One finished file costs one credit, and a file that fails costs nothing. A verified free account gets 50 credits a month, so you can run a real Zap before you pay.
Can Zapier make images too, or only PDFs?
Both. Make an Image gives you a PNG, JPEG, or WebP at the size you designed. It fills a design you saved, so the words and colours come out right every time.
Where do I make the design?
In the thirds.ai studio, or ask your AI assistant, like ChatGPT or Claude, to make one for you. Zapier fills it in from then on, so you never open a design tool for a single file. Use thirds.ai with Make or n8n instead.
