Content extensions

What are content extensions? Why create one?
A content extension imports third-party content, such as photos and illustrations, into Canva. Users can access this content via the side panel and add it to their designs.
To create a content extension from scratch, check out the Quick start guide.

How content extensions work

At its most basic, a content extension is a REST API.
Canva expects this API to have the following endpoint:
As a user interacts with a content extension via Canva's UI, Canva sends requests to this endpoint and expects to receive responses in a format that it understands. Based on these responses, Canva knows what content to render in the side panel.

Supported content types

A content extension can provide users with two types of content:
  • Images, such as JPEG, PNG, and SVG files.
  • Embeds, such as animated GIFs, YouTube videos, and Instagram photos.

Request-response cycle

This is the request-response cycle of a content extension:
Canva sends additional requests if the extension supports authentication.


const axios = require("axios");
const express = require("express");
const app = express();
app.use(express.static("public"));"/content/resources/find", async (request, response) => {
const { data } = await axios.get("");
const resources = => {
return {
type: "IMAGE",
name: ||,
thumbnail: {
url: resource.download_url,
url: resource.download_url,
contentType: "image/jpeg",
type: "SUCCESS",
app.listen(process.env.PORT || 3000);
