What is QR & Barcode?
The QR & Barcode API creates standard QR codes along with multiple barcode types such as Code 128, EAN-13, Data Matrix, and PDF417, returning results as either SVG or PNG images.
It is useful for developers building applications that require on-demand code generation for inventory tracking, product labeling, ticketing, or document workflows.
What you can build with QR & Barcode
Inventory label generation
Developers call the API to create EAN-13 or Code 128 barcodes for physical products, receiving PNG files that are printed directly onto warehouse labels.
Event ticketing system
Integrate the API to produce unique QR codes for digital tickets, embedding the SVG output into web pages or mobile apps for scanning at entry points.
Shipping and logistics docs
Generate PDF417 or Data Matrix barcodes containing tracking data and embed the PNG images into invoices or packing slips generated by backend services.
