setting soap request properties from T-sql - sql-server

Question

Below is the code I am using to connect to my api server. All works fine for other calls, but when it comes to uploading images, it's not working. If I copy the code into SoapUI and run from there, it does work but in SoapUI I have to change the request property "Enable inline files" to true.
Does anyone knows how I can pass that property value in my below code?
declare
#Url varchar(1024),
#HttpMethod varchar(10),
#ParamsValues varchar(1024),
#SoapAction varchar(8000)
DECLARE #t table (ID int, strxml xml)
set #Url = 'https://api.my.com/api.asmx'
set #HttpMethod = 'soap'
set #SoapAction = '<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:apic="http://apiconn.com">
<soap:Header/>
<soap:Body>
<apic:AddBook>
<apic:addbookID>18</apic:addbookID>
<apic:data>file:C:/temp/Book2.csv</apic:data>
<apic:dataType>CSV</apic:dataType>
</apic:AddBook>
</soap:Body>
</soap:Envelope>'
