Simplify Your QR Code Generation with Dowell’s API
Dowell QR Code Generator API involves the creation of QR codes through an API. QR codes are two-dimensional barcodes that can store data such as URLs and other types of information.
To use this API, clients can send HTTP requests to create, retrieve, update, or delete QR codes. The API supports the creation of QR codes with various options such as custom colors, logos, and sizes
Supports creation of QR codes with various options such as custom colors, logos, and sizes.
Returns the details of a QR code, including qrcode_id, qrcode_image_url, logo_url, logo_size, qrcode_color, link, company_id, product_name, created_by, description, and is_active.
Updates various properties of a QR code such as the company ID, QR code image URL, logo URL, logo size, QR code color, link, product name, created by, description, and is_active status.
Authentication: Users authenticate themselves with the API by obtaining an API key or using OAuth tokens for secure access.
Request Creation: Users make an HTTP request to the API endpoint, specifying the data they want to encode into the QR code. This can include URLs, text, contact information, etc.
Customization (Optional): Users can include additional parameters in the request to customize the appearance of the QR code. This may include options such as color, size, error correction level, and even adding a logo or image to the center of the QR code.
API Processing: The API processes the request and generates a QR code based on the provided data and customization options. It encodes the data into a two-dimensional barcode format suitable for scanning
Response Retrieval: Once the QR code is generated, the API returns a response to the user, typically containing the image data of the QR code in a suitable format such as PNG or SVG.
Usage: Users can now utilize the generated QR code in various ways according to their needs.
Scanning: End-users scan the QR code using a smartphone or QR code scanner application. This decodes the information encoded in the QR code, redirecting users to the specified URL, displaying text, adding contact details, etc.
Ease of Integration: With simple HTTP requests, clients can seamlessly integrate the API into their applications or websites, saving time and effort in development and implementation.
Versatility: The API supports the creation of QR codes capable of storing various types of information such as URLs, text, contact details, and more, catering to a wide range of use cases and applications.
Reliability: Dowell QR Code Generator API ensures reliable performance and uptime, providing users with a dependable solution for generating QR codes whenever needed without interruptions.

This React code defines a functional component App
that creates QR codes using a form. It allows users to upload an image (logo), specify details such as company ID, creator, color, link, and description. The component sends a POST request to a specific URL with the form data using Axios when the form is submitted. Successful and failed responses are logged to the console. It also handles input changes and file uploads using state and event handlers. Don’t forget to replace '<your-api-key>'
with your actual API key.

Step 1 : Set up the Dowell QR Code Generator API name and the base url. It’s a prerequisite to have WP-GET API installed in your wordpress API.
Step 2: Set up the api endpoint and the request body. the endpoint should have the api key and request body should have the necessary body post fields.
Step 3: Test endpoint to get JQuery response from the API. Go to the url provided by the API output to confirm that theAPI works as expected and that the QR Code has been generated and is visible. The Data output provided by the API below is a result of calling the API qrcode_image_url is the url of the image created.
This is a GET request that you send to QR Code Generator and what the API does is it fetches all the previous QR codes that you have generated. The screen shot below shows how you should setup the parameters to fetch data from this API.
Below is the data output provided by calling the QR Code generator API with the parameters above.
This is a PUT request that you send to QR code generator that you use to update your previously generated QR Code. You are able to update logo, company_id, created_by, qrcode_color, link and description. The screenshot below will show you how to set QR code generator in your wordpress website.
This is a GET request to find a single qrcode that was previously generated using QR Code generator. on your endpoint you just have to add the id of your QR Code that was previously generated.Below is a screenshot to guide you on how to set the endpoint.
