Hello,

Adding your own logo on the QR Code is one of the basic functionalities of the LinQR API and is very often used by our users.

To do this, you can use at least three different approaches:

1. You can send an image directly with a multipart request along with all other QR Code specification. You can do it by calling any of https://qrcode3.p.rapidapi.com/qrcode… endpoints with

   request body content-type: multipart/form-data
   field image -> content-type: image/png, image/jpeg, etc.
   	your image 
   field metadata -> content-type: application/json
   	{"data":"QR Code data"}
   

2. If you have a server where you store your image, you can give us the URL to the image to be placed on the QR Code. This can also be done by calling any of https://qrcode3.p.rapidapi.com/qrcode… endpoint

   request body content-type: application/json
   {"data":"QR Code data", "image":{"uri":"http://yourserver.com/someimage.png"}}
   

3. The most advanced option is to use our cloud to store images. This option is especially recommended when generating a large number of codes. We store images in a high-availability cache system, which allows us to generate codes much faster than with the other two options. This requires two API requests. The first saves the image into our storage via https://qrcode3.p.rapidapi.com/images

   request body content-type: multipart/form-data
   field image -> content-type: image/png, image/jpeg, etc.
   	your image 
   response: {"id":"image_identifier", ....}
   

   Now you can use your image for any number of consecutive QR Codes. We will keep it until you explicitly request its deletion. You generate the Code with a similar request to any of https://qrcode3.p.rapidapi.com/qrcode… endpoint

   request body content-type: application/json
   {"data":"QR Code data", "image":{"uri":"storage://image_identifier"}}
