CANVA API

Canva API: what you can build with it, and what you can't

A developer's guide to the Canva Connect API and Apps SDK: the 14 endpoint groups, why neither one embeds a design editor in your product, when Canva's API is the right choice, and what to use when it isn't.

Canva has two developer products, and most teams pick the wrong one because the names do not say which direction the integration runs. This page explains what each one does, what neither one does, and how to tell within five minutes which you need.

Quick disclosure: we build Polotno, an editor SDK, so we are one of the answers at the bottom of this page. That only works if the rest is accurate, so everything below is checked against Canva's own developer documentation and linked so you can verify it.

The short answer

Connect API

Your system talks to Canva. Upload assets, create designs from brand templates, export finished files back. Users still design in Canva.

Apps SDK

Your app runs inside Canva. It loads in an iframe in the Canva editor's object panel, next to Canva's own tools.

Neither embeds an editor

No Canva product puts a design canvas inside your product's UI, under your branding, for users without Canva accounts.

Both official routes point the same way: toward Canva. That is a deliberate product decision, not a gap they forgot to fill. If your requirement is "our users design inside our app", the Canva API is not the tool, and no combination of its endpoints becomes one.

What the Connect API actually does

The Canva Connect APIs are a REST API with OAuth, covering fourteen groups:

Designs

Create designs, list a user's designs, read metadata and pages.

Autofill

Push data into a brand template's named fields to produce a finished design.

Brand templates

Publish designs as templates, list them, and inspect which fields are autofillable.

Exports

Asynchronous export jobs that return a downloadable file link.

Assets

Upload by file or URL, then read, update, and delete.

Design imports

Bring designs in from an external application.

Folders

Create and manage folders, list contents, move items.

Comments

Create threads and replies, read thread metadata.

Merges and resizes

Asynchronous jobs to merge designs or resize them.

Analytics

Design views, viewers, page and link analytics over time.

Webhooks

Events for access requests, approvals, comments, suggestions, and sharing.

Users and auth

Current user profile, account capabilities, and OAuth token lifecycle.

That is a capable workflow API. If your product manages marketing assets and your users already live in Canva, it does real work: sync an asset library, generate a thousand localised variants from one brand template, pull exports back into your CMS, and get a webhook when someone comments.

What it does not do

No embeddable editor

No endpoint returns an editor you can mount in your own page. Editing happens on Canva's site, in Canva's interface.

No white labelling

Your users see Canva's brand, Canva's UI, and Canva's feature set, because they are using Canva.

Users need Canva accounts

The API authorises through OAuth against a Canva user, so every person who designs needs an account and has to grant access.

The data model is Canva's

Designs live in Canva's format and storage. You can export renders and import files, but you do not own the document as structured data you can query or transform.

Distribution is gated

A private integration is limited to your own team and requires a Canva Enterprise plan. A public integration has to pass Canva review.

The last one surprises people late in a project. Building an integration your customers will use means shipping a public app through Canva's review process, on Canva's timeline.

The Apps SDK runs the other way

The Canva Apps SDK is often suggested when the Connect API turns out not to embed an editor. It does not solve that problem — it inverts it.

An app built with the Apps SDK is a JavaScript bundle that runs inside an iframe in the Canva editor's object panel. Your interface appears as a side panel next to Canva's own tools, and it can drive the canvas programmatically. Distribution is either the Canva Apps Marketplace or a private team workspace.

So the Apps SDK puts your product inside Canva. The Connect API pipes data between your product and Canva. Neither puts Canva inside your product, which is the thing most teams searching for "Canva API" are actually trying to do.

When Canva's API is the right choice

Genuinely often. Use it when:

Your users already work in Canva and like it — fighting that is a bad trade
You need bulk generation from brand templates marketing already maintains in Canva
The integration is asset flow, not editing: assets in, renders out, CMS in sync
You want Canva's template library, stock content, and AI features without building them
You are on Canva Enterprise already and the integration is internal

In those cases an editor SDK is the wrong answer and would cost you more work for a worse result. Start at canva.dev and check the current plan requirements on Canva's own pages, since those change.

When you need an editor instead of an API

The requirement is different when any of these is true:

Users design inside your product, and never see another brand
Users must not need a third-party account to create something
You need the design as structured data you own — to validate, price, generate, or print it
You control the surface: which tools appear, what fonts and templates exist, how export works
You cannot send customer artwork to a third party for legal or compliance reasons

That is a design editor SDK, which is a different category of product from a workflow API.

What that looks like

This is our answer, so weigh it accordingly. Polotno is a JavaScript SDK that renders a full design editor inside your application. The editor below runs in this page:

Every design is plain JSON, so you can generate one from your own data, store it in your own database, and render it yourself. There is no Canva account, no review process, and no other brand in front of your users.

The honest trade: you do not get Canva's stock library, its template catalogue, or its brand recognition, and you take on integration work that a hosted API does not ask of you. If Canva's ecosystem is the point, the Connect API is the better tool.
