This guide explains how to embed ebooks into external websites.

​
Getting started

  • Ebook digital product ID
  • Fermion API key
  • Access to your website’s codebase

​
Step 1: Obtain the ebook digital product ID

Each ebook on fermion has a unique identifier. For example 6779080e80ec97e953a17971. First, go to Manage features tab on your instructor dashboard and enable Digital products After that, go to eBooks inside Digital products to create and upload an ebook if you haven’t. You can find the ebook digital product ID in the URL.

​
Step 2: Generate an Embed Token

You’ll need to generate a JWT (JSON Web Token) to authenticate the embed. Here’s how to create one using the jsonwebtoken package: 
import jwt from 'jsonwebtoken'

const payloadObject = {
	/* ... see the valid schema of the object below ... */
}

const jwtToken = jwt.sign(payloadObject, 'FERMION_API_KEY', {
	expiresIn: '10h',
})
The payloadObject must conform to the following zod schema: 
z.object({
	ebookDigitalProductId: z.string().min(1),
	userEmail: z.string().email(),
	userId: z.string().min(1),
	userPhoneNumber: z.string().min(1).or(z.null()),
})
Important notes:
  • Replace FERMION_API_KEY with your actual API key and provide a unique user ID for each viewer.
  • Make sure to set a validity on JWT token (recommended validity is 10h-20h)
Fermion uses the same zod schema as above internally to validate your JWT payload.

​
Step 3: Embed the ebook

Add this iframe to your website where you want to embed the ebook: 
<iframe
	width="1280"
	height="720"
	src="https://acme.fermion.app/embed/ebook?token=your_token_here"
	title="Ebook"
	frameborder="0"
	allow="allow-same-origin; camera *;microphone *;display-capture *;encrypted-media;"
	referrerpolicy="strict-origin-when-cross-origin"
	allowfullscreen
>
</iframe>
Make sure you replace acme.fermion.app with your fermion school URL.
This should embed your ebook and display it on your website.
