Question

How to upload an image into the application server project using WebAPI?

Answer

The files can be uploaded by any of the following methods:

AddNewImage
AddNewDocument
AddNewPage

These methods take a File object as one of the arguments. The File object consists of the name of the file and binary data of the file. The binary data is a Base64 bytes sequence.

For the test purpose, you might use an online converter. For example, https://www.base64encode.org/. The result may look like this:

Paste the full text into the field Bytes property of the File object in your API request.

For purpose of automatical conversion, the appropriate libraries or other tools should be used. For example, the C# .NET framework has the following tools built in: https://docs.microsoft.com/en-us/dotnet/api/system.convert.tobase64string?view=net-5.0
