How to update the content of a website

Question

Can I know how to update a content of your website every single day e.g (blog, news, videos, or images) that needs to be new everyday

Answer 1

it depends of the website...
some engine have dedicated tools, some others provide CRUD API, while most of them are "manually" updated (by uploading files)...

in all cases, for write operations, you'll need credentials for the website ^^
