Kernex Uploads

Getting Started

Uploads are a way to store files in Kernex's cloud storage. They are working the same exact way as the Resources, but they are optimized for file storage. Unlike the resources, that are defined by you, the uploads are managed by Kernex and they have a fixed structure.

Please check the Rest API section for more information about how to interact with the API.

Authorization

Please follow the REST API Authorization section for more information about how to authorize your requests.

Upload Structure

The upload structure is the following:

_id (string, readonly): the unique identifier of the upload
url (string, readonly): the absolute URL of the file, that you can use to access the file.This is the URL that you should use when you want to display the file in your website.
title (string): the title of the upload
description (string): description of the upload
name (string, readonly): the name of the file
fileId (number, readonly): an id of the file (used internally by Kernex), in the storage bucket.
ext (string, readonly): the extension of the file
contentType (string, readonly): the content type of the file
createdAt (string, readonly): the date when the upload was created
updatedAt (string, readonly): the date when the upload was updated

Base Endpoint URL

The base endpoint URL for the uploads is:
