In a nutshell: QR Code APIs enable developers and businesses to programmatically generate, customize, and manage QR Codes at scale. Platforms like Scanova QR Code Generator offer comprehensive API solutions with dynamic code creation, real-time analytics, custom branding, and enterprise-grade security. This guide covers implementation steps using a reliable tool, best practices, and how to choose the right QR Code API for your business needs.
QR Codes have evolved from simple black-and-white squares to powerful business tools that bridge offline and online experiences.
With over 11 million households scanning QR Codes, businesses need robust QR Code APIs to generate, customize, and manage these codes at scale.
If you are a business owner or a developer planning on using QR Codes in your information systems or business applications, you’d want QR Codes in bulk. Plus, you would want to be able to generate QR Codes in real-time for your end-users.
And here’s the thing: To do that, it’s not feasible for you to head on to your QR Code generator every time you need to create a QR Code.
A QR Code API allows developers to programmatically create and manage QR Codes without manual intervention, enabling seamless integration into existing business systems.
Whether you’re building a ticketing platform, managing inventory, or creating marketing campaigns, the right QR Code API can transform how you handle data transmission and customer engagement.
In this guide, we’ll discuss in detail QR Code APIs, their best practices, and how you can choose the right QR Code API for your business needs.
Let’s begin!
A. What makes QR Code APIs essential for modern businesses?
QR Code APIs solve critical business challenges that manual QR Code generation simply cannot address.
Traditional static QR Code creation becomes almost impossible when you need to generate hundreds or thousands of codes, track performance metrics, or update destination content after deployment.
Now here’s what you should understand: Static vs Dynamic QR Code APIs:
- Static QR Codes contain fixed information encoded directly into the code structure
- Dynamic QR Codes redirect to a URL that can be updated post-creation, enabling content changes without reprinting
The power of QR Code APIs lies in their ability to create dynamic codes that provide analytics, enable content updates, and integrate with existing business workflows.
B. What are some popular use cases of QR Codes API?
QR Code API can be used in practically any use case where you need to generate QR Codes in real-time. Here are some popular and common use cases:
1. Document authentication
QR Codes are now being extensively used for document authentication purposes.
You can generate the QR Codes that link to information in your database and add them to required documents.
2. Coupons
It is common for businesses to hand out coupons to give discounts. They help attract customers. But here’s the problem: customers have a hard time remembering the coupon codes due to the randomness of encoded characters.
But with QR Codes, they no longer need to remember the code. And with API, you can generate these coupon codes in real-time.
3. Visitor pass
Many institutions and organizations use visitor passes to allow visitor entry. And it’s common to spot a QR Code on them for security and authentication purposes.
For example, QR Code on a boarding pass. With QR Code API, you can enable QR Code generation smoothly for your visitor management process.
4. Product tags
You would’ve seen QR Codes on product packaging. Ever wondered what these are for?
They usually serve one of the two major purposes. The first is to provide product information that cannot be added to the limited printing space on the packaging.
The second is to encode product ID or serial number for inventory tracking and logistical operations.
Now, before we learn more about what QR Code APIs can do for your business, let’s compare some of the best QR Code API solution providers of 2025.

F. Type of QR Codes that can be generated via API
You can generate various types of static QR Codes programmatically via API. Here is a list of them:
1. Website URL QR Code
Do you want to take the end-users to a website when they scan the QR Code? Then Website URL QR Code is your way to go.
2. Text QR Code
As the name suggests, Text QR Code encodes text and numbers. It is used in a variety of use cases such as encoding the serial number of the product, product information, coupon codes, and terms and conditions.
3. Vcard QR Code
A Vcard or business card QR code API allows you to encode contact details. For example, your name, company name, contact number, email address, and fax number. When scanned, it shows the encoded content details to the end-users.
4. WiFi QR Code
The WiFi QR Code API helps create QR codes that, when scanned, allow end-users to join a particular Wi-Fi network.
It eliminates the need for end-users to manually type the password to access the WiFi network.
5. Google Maps QR Code
With Google Maps QR Code API, you can encode location coordinates into the QR Code in bulk.
When end-users scan it, they’ll be redirected to the location on the maps application on the phone.
6. Phone Call QR Code
Phone QR Code allows you to encode a phone number in it. When end-users scan it, they can readily give a call on the encoded number rather than having to manually type it.
7. Email QR Code
An email QR Code API allows you to encode the recipient’s email address in bulk and generate QR codes in real-time.
When end-users scan it, the email gets generated on their phone with the recipient’s address in the required field. They can then write the subject and email body to hit the send button.
8. SMS QR Code
Want your users to send a pre-drafted SMS to you? An SMS QR Code API can help you do it. When scanned, it loads a pre-drafted SMS along with the recipient’s phone number. It also allows the end-users to edit the SMS before sending it out.
9. Social Media QR Code
Whether you’re an employer, teacher, or agency, you might need to create bulk social media QR codes.
These codes can link to multiple social media profiles for different brands or people. In such cases, it’s a good idea to use an API for social media QR codes.
G. How to generate QR Codes via API
Now you know the types of QR Codes you can generate via API and their design potential. The next question is – how to create one?
To do that, you’ll need a suitable online bulk QR Code provider. Using Scanova’s QR Code API, here’s how you can proceed:
1. Log in to your Scanova account and go to Settings → API.

5. In the request body, add the content you want to encode and specify design options like size, error correction level, logo, or colors.
6. Click Execute to send the API request. You’ll receive a response that shows cURL, Request URL, Response Body, and a preview image of the generated QR Code.
7. Copy the Response URL, which points to the QR Code image. Use it in your system or app to display or save the code.
8. Always scan-test the generated QR Code to ensure it works before integrating it into your production workflows.
