▣ OUTPUT KIT

Generate QR Code as SVG/PNG API

What it does

QR Code Generator creates a QR code image from text, URLs, Wi‑Fi settings, vCards, or TOTP auth data. Send your payload in the request body and get back a binary QR code you can render, download, or embed.

You control the code’s appearance with bg and fg hex colours, ecc error correction level, size in pixels, margin, and output format (png or svg). The type field selects the payload format: text, url, wifi, vcard, or otpauth.

For contact and network codes, include the matching fields such as vcard_name, vcard_email, vcard_phone, vcard_org, vcard_url, or wifi_ssid, wifi_password, wifi_encryption, and wifi_hidden. For authenticator codes, supply otp_issuer, otp_account, and otp_secret.

Use QR Code Generator when you need branded QR assets for receipts, posters, onboarding flows, login setup, or share links. It returns a binary image, so you can place the generated code directly into a page, email, or PDF workflow.
