Generate QR Code via API

The Generate QR Code endpoint creates a QR code image from a string of data you provide. You can customise its appearance by changing the color or embedding a logo directly in the centre. The generated QR code is saved as an asset in your library, making it easy to reuse across multiple documents.

Key parameters include:

• content – The text or URL you want to encode.
• color – The colour of the QR code in hexadecimal format (e.g., #000000 for black).
• logo_url or logo_base64 – A URL or base64 string for an image to be placed in the centre of the QR code.
• output - The format for the response, which can be a URL or a base64 string.
