Heyzine API
Application programming interface for developers or NoCode tools to integrate flipbooks in applications or workflows.
Getting started
Heyzine provides a comprehensive and flexible API to manage flipbooks in your account. It allows you to create, list and delete flipbooks, manage the access list with password, get embed codes and receive leads via webhooks. The API uses either a Client ID or an API key for authentication. When the API Key is required, you must provide it in a header this way:
Authorization: Bearer API_KEY
PDF to Flipbook Conversion
Link Conversion
Create a link with parameters pointing to your pdf file and use it in anchors, iframes, dialogs, or anywhere else. The link will redirect to the final flipbook url. The conversion process starts with the first access, so it can take some time to load the first time you open it. To convert server-side and avoid revealing the original url, you can use the /rest endpoint and get a json response.
Link format
https://heyzine.com/api1?pdf={pdf url}&k={client id}
Basic example
https://heyzine.com/api1?pdf=https://codingfocus.com/sample.pdf&k=d3m0
Titles and controls
https://heyzine.com/api1?pdf=https%3A%2F%2Fcodingfocus.com%2Fsample.pdf%3Fexample2&t=Test%20title&s=Test%20subtitle&d=1&k=d3m0

REST API Conversion
Call the Sync REST endpoint client or server-side, to convert the PDF and get a JSON response with the links to the flipbook, thumbnail, and PDF. The endpoint will send the response right after the conversion ends. You have to make sure the client has a long enough time out for the largest documents.
Call the Async REST endpoint to get the JSON response immediately in case you don't want to wait for the conversion process. Subsequent calls to the endpoint with the same parameters will return the current state of the conversion. (started, processed, or failed). During the conversion time, flipbook links will show a not-found page.

jQuery PDF to flipbook
jQuery plugin to convert all the PDF links on your site to flipbooks.
Usage steps:
1.-Include jquery and the plugin through a CDN or download and include them in your project:
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script type="text/javascript" src="https://cdnc.heyzine.com/release/jquery.pdfflipbook.4.js"></script>
2.-Call the plugin with the Client Id to convert all the links:
$('a').pdfFlipbook({ key: 'd3m0' });
3.-Optionally, you can use DOM attributes to customize the resulting flipbook and presentation:
| Parameter | Required | Description | Example |
|---|---|---|---|
| flipbook | Optional | When the element has an href, this attribute will be ignored, otherwise defines the url of the pdf file and binds a click event for navigation. | <span flipbook="/link-to-pdf.pdf">This is a flipbook</span> |
| title | Optional | Title for the page | <a flipbook="/link-to-pdf.pdf" title="title">This is a flipbook</a> |
| subtitle | Optional | Subtitle for the page | <a flipbook="/link-to-pdf.pdf" subtitle="subtitle">This is a flipbook</a> |
| showdownload | Optional | Show the download button on the flipbook page | <a flipbook="/link-to-pdf.pdf" showdownload>This is a flipbook</a> |
| showmodal | Optional | Opens the flipbook in a simple modal over the page | <a flipbook="/link-to-pdf.pdf" showmodal>This is a flipbook</a> |
See the jquery demo here: Demo
oEmbed API
oEmbed is an API that allows third-party websites and apps to fetch an Html embed code to display Heyzine flipbooks.
Discovering oEmbed URIs
Most flipbooks support oEmbed. Your application can discover the corresponding oEmbed URI by searching the flipbook for a element with the type "application/json+oembed".
For example, the flipbook sample here, includes the following link tag:
<link rel="alternate" type="application/json+oembed" href="https://heyzine.com/api1/oembed?url=https%3A%2F%2Fheyzine.com%2Fflip-book%2Fdce36e099f.html&format=json" title="PDF to Flipbook | Heyzine" />
Using oEmbed data from Heyzine in your app or website
Send a GET request to /api1/oembed, with the url parameter set to a flipbook link to get his oEmbed data.
Heyzine supports the standard oEmbed 1.0 parameters (url, format, maxwidth, and maxheight).
Request
