Create an API for receiving files

Hi Community,

i want to create an api which is able to receive files into a table with a blob column.

Solution Example:

An external webservice will do a html post to my website to send files (more than one) with credentials. Theses files must be stored into a table with blob column and a file name column.

Which kind of API should be generated ?

Is there a simple solution guide to work with ?

Thanks
