Get document from the third party system

Question

Hi All, 
 There is a requirement to a get document from the third party system, 
 Can someone suggest a way what is the best way to get the document from the third party system? 
 
 Below is the implementation that I know, Apart from these any plugins or any other things? 
 1. Third party systems will return url where the file is located. As soon as user clicks the document can be downloaded into the local system. 
 2. Thir party systems will return the document in binary format and Integration can convert binary to document from the respsonse. 
 Apart from this Do we have any other way to get the document from the third party systems? 
 
 My Next question is 
 If other systems want to post a document into appian, how exactly web appi will configure it, how the request hader document format will be? 
 
 Thanks in Advance!

Hi Hemaashri , Commonly we get files into Appian in certain ways:

Direct URL

Binary response

Base64 response

SFTP download

Email polling

RPA

Webhook

If you want other systems to post documents into appian using Web API, Header could be: 
 Content-Type: multipart/form-data; boundary=----WebKitFormBoundary
 
 Body you need to send is : ------WebKitFormBoundary
Content-Disposition: form-data; name="file"; filename="example.pdf"
Content-Type: application/pdf

(binary content)
------WebKitFormBoundary--
 
 Use a!startProcess() inside the Web API to call a Process Model that stores the file in a Appian folder. Hope this helps you!!!
