Integrating PDF Generator API with Your Wix Website

In this article, we will explore how to integrate the PDF Generator API with your Wix website to create custom PDFs. We will cover the step-by-step process of setting up API credentials, installing the necessary npm packages, creating the backend file, and explaining the code. Additionally, we will test the function to ensure everything is working correctly. Finally, we will discuss the next steps and how to use the API with the frontend of your website.

1. Introduction

Integrating the PDF Generator API with your Wix website can enhance the functionality by allowing you to dynamically generate custom PDFs. Whether you need to create invoices, reports, or any other document, this integration will enable you to automate the process.

2. Setting up API Credentials

Before we begin the integration process, we need to save the API key and secret in the secrets manager. This is an important step as it ensures the security of your API credentials. We will follow the specific instructions provided in the documentation to store the API key and secret correctly.

3. Installing npm Packages

To expedite the integration process, we will be using npm packages. Specifically, we need to install the JSON Web Token and PDF Generator API Client packages. These packages will assist us in handling authentication and generating PDFs efficiently.

4. Creating the Backend File

Next, we will create a backend file in Wix where we will add the starter code provided by the integration. This code includes various functions that will be used in the integration process. We will go through each function briefly to understand its purpose and functionality.

5. Explaining the Backend Code

In this section, we will examine the backend code in detail. We will start by discussing the Create JSON Web Token function, which generates the token using the API key and secret. Then, we will explore the Create Client function, which utilizes the JSON Web Token to authenticate the requests.

6. Generating PDFs

One of the key functions we will be focusing on is the Generate PDF function. This function is responsible for creating the custom PDFs. We will delve into the parameters required for this function, such as workspace identifier, template ID, merge data, and merge options. Additionally, we will look at the helper functions provided for generating PDF URLs and PDF binaries.

7. Testing the Function

To ensure that everything is working as expected, we will test the Generate PDF function. We will provide the necessary parameters and check if the function returns a URL to the generated PDF. This step will help us verify that the integration is functioning correctly.

8. Next Steps

Once we have successfully integrated the PDF Generator API with our Wix website, we can explore further possibilities. In the next video, we will learn how to use the PDF URL in different ways on our website. Additionally, we will discuss integrating the function with the frontend to generate PDFs directly from the user interface.
