Uploading

Upload API

Build custom uploading flow using Upload API directly or with an API client.

curl -F "UPLOADCARE_PUB_KEY=demopublickey" \
     -F "file=@sample-image.jpeg" \
     "https://upload.uploadcare.com/base/"bash

Once a file is uploaded, it's available by a URL with the UUID:

https://ucarecdn.com/017162da-e83b-46fc-89fc-3a7740db0a82/

File Uploader

• We’re building the next version of File Uploader. Check out the beta.

We’ve built a UI that uses Upload API so you don’t have to.

npm install uploadcare-widgetbash

import uploadcare from 'uploadcare-widget'javascript

You can get a file uploader instance and configure it with configuration object:

<input id="uploader" type="hidden" />html

const widget = uploadcare.Widget("#uploader", { publicKey: 'YOUR_PUBLIC_KEY' });javascript

Replace YOUR_PUBLIC_KEY with your public API key.

It will appear like this (clickable):

This responsive widget works in all modern browsers, on all devices and it has a plenty of features and customization options.
