If you have the request data stored in property you can use 'Map From Clipboard' in methods tab of connect-REST rule otherwise 'Map From Constant'

Hi,
if your Passing the request as attachment the following steps can be used.
Analysis of the Connect-REST multipart functionality (attachments )
In general we have four properties to be set on pyRequestAttachmentPage(Data-ServiceMessage)
The generation of multipart request depends on the four properties which is present in Data-ServiceMessage class
1)pyAttachFileNames
Hi,

Analysis of the Connect-REST multipart functionality (attachments )
In general we have four properties to be set on pyRequestAttachmentPage(Data-ServiceMessage)
The generation of multipart request depends on the four properties which is present in Data-ServiceMessage class
1)pyAttachFileNames
2)pyAttachTypes
3)pyAttachValues
4)pyAttachNames
UseCase-1 (Setting all the properties)-Generates the following message
POST / HTTP/1.1
Content-Length: 220
Content-Type: multipart/form-data; boundary=QHdb-kDg6LLU0cJOgInu1ExR_GY95o
Host: google.com:8877
Connection: Keep-Alive
User-Agent: Apache-HttpClient/UNAVAILABLE (java 1.5)
--QHdb-kDg6LLU0cJOgInu1ExR_GY95o
Content-Disposition: form-data; name="attachname"; filename="santy.txt"
Content-Type: application/json
Content-Transfer-Encoding: binary

--QHdb-kDg6LLU0cJOgInu1ExR_GY95o--
Here is the summary of each type
Value of pyAttachTypes is content type –see highlighted in blue
Value of pyAttachNames and pyAttachFileNames is a part of content disposition header-see highlighted text in yellow
Over all content type of the message is multipart/form-data-highlighted in red
Usecase-2 Not setting pyAttachTypes - content type of individual part is defaulted to application/octetstream
POST / HTTP/1.1
Content-Length: 248
Content-Type: multipart/form-data; boundary=Qj8f74fBMDunqoRSdJqh38KRUxJIzXMN6hLe2njS
Host: google.com:8877
Connection: Keep-Alive
User-Agent: Apache-HttpClient/UNAVAILABLE (java 1.5)
--Qj8f74fBMDunqoRSdJqh38KRUxJIzXMN6hLe2njS
Content-Disposition: form-data; name="attachname"; filename="santy.txt"
Content-Type: application/octet-stream
Content-Transfer-Encoding: binary

Usecase-3Not setting pyAttachFileNames
pyAttachFileNames is defaulted to pyAttachnames
POST / HTTP/1.1
Content-Length: 229
Content-Type: multipart/form-data; boundary=b4S38RrAPScj8swlzOyPRB79OzD0f6Uxhy
Host: google.com:8877
Connection: Keep-Alive
User-Agent: Apache-HttpClient/UNAVAILABLE (java 1.5)
--b4S38RrAPScj8swlzOyPRB79OzD0f6Uxhy
Content-Disposition: form-data; name="attachname"; filename="attachname"
Content-Type: application/json

Not setting pyAttachname and pyAttachFileNames - No data is sent as binary attachment, at least attachname is mandatory
POST / HTTP/1.1
Content-Length: 37
Content-Type: multipart/form-data; boundary=q75QKTzvoo0A_ZoTMqSZhaDh3AVQgua
Host: google.com:8877
Connection: Keep-Alive
User-Agent: Apache-HttpClient/UNAVAILABLE (java 1.5)
--q75QKTzvoo0A_ZoTMqSZhaDh3AVQgua--
Conclusion: pyAttachname,pyValues is mandatory to be set, pyAttachtype and pyAttachFilename is also optional
pyAttachtype generates content-type of the part
if not given falls back to default application/octetstream
pyAttachname generates the content-disposition header where name is the parameter
if pyAttachname option is not given the file name is defaulted to whatever value is specified in attachname

We have tried the configuration step as mentioned in the PDN article. But we are not able to see if the request that is getting triggered is actually having the content we are setting or not. We are not able to see it in the tracer, please let us know if this will be logged somewhere or is there anyway this can be traced? We would like to see the content of the attachment that is being formed.

Did you figure this one out?
We are also have similar requirement, however even after using the steps mentioned above we are getting 400 response code and are not able to set the content type as expected.

Hi, we also have a similar requirement wherein we need to send .html file as an attachment included in the request for Connect-Rest.
I tried setting the base 64 encoded value of html stream in pyRequestAttachmentPage.pyAttachValues(1) but still getting response code as 400.
Did you get anything how to pass attachments in the request for Connect-Rest ?

Please note that REST Connector has a "log data if it's a string" behavior which may be making it so people do not see the request/response in the logs for multipart data.
Check if the string data gets logged correctly and we can enter an enhancement request on your behalf for multipart type.
