ShareX Configuration

This URL Shortener has fully support with ShareX. To use it, just import the configuration to your ShareX. For that you need to open the Destination settings => Other / Custom uploaders => Import => From Clipboard.

After you've done this, you need to set it as your standard URL Shortener. For that go back into your main menu => Destinations => URL Shortener => Custom URL Shortener.

Curl

HTTP Endpoints:

/api/v1/create POST

Create is the handler for creatng entries, you need to provide only an URL. The responsive will always be JSON encoded and contain an URL with the short link.

There is a mechamism integrated, that you can call this endpoint with the following techniques:

• application/json
• application/x-www-form-urlencoded
• multipart/form-data

In all cases only add the long URL as a field with the key URL and you will get the response with the short URL.

/api/v1/info POST

This handler returns the information about an entry. This includes:

• Created At
• Last Visit
• Visit count

To use this, POST a JSON with the field id to the endpoint. It will return a JSON with the data.
