Hi All

I am trying to send a pdf file through REST Request however the file sent to the destination is broken and invalid. I have the below header values and esql code for MIME. Can some one please let me know what is missing?

I think you might have more luck asking ACE questions in the AppConnect community rather than the APIConnect one? :-)

Hi All

I am trying to send a pdf file through REST Request however the file sent to the destination is broken and invalid. I have the below header values and esql code for MIME. Can some one please let me know what is missing?

SET OutputRoot.HTTPRequestHeader."Content-Type" = 'application/pdf';

SET OutputRoot.Properties.ContentType = 'multipart/form-data; boundary=' || myBoundary; (myBoundary is UUID value)
SET OutputRoot.HTTPRequestHeader."Content-Disposition" = 'attachment; filename=' || InputRoot.MQRFH2.usr.fromFile;

CREATE FIELD OutputRoot.MIME TYPE Name;

DECLARE M REFERENCE TO OutputRoot.MIME;

CREATE LASTCHILD OF M TYPE Name NAME 'Parts';

CREATE LASTCHILD OF M.Parts TYPE Name NAME 'Part';

DECLARE P1 REFERENCE TO M.Parts.Part[1];

CREATE FIELD P1."Content-Disposition" TYPE NameValue VALUE 'form-data; name="attachment"; filename=' || InputRoot.MQRFH2.usr.fromFile;

CREATE FIELD P1."Content-Type" TYPE NameValue VALUE 'application/pdf';

CREATE FIELD P1."Content-Id"   TYPE NameValue VALUE 'p1';

CREATE LASTCHILD OF P1 TYPE Name NAME 'Data';

CREATE LASTCHILD OF P1.Data DOMAIN('BLOB') VALUE InputRoot.BLOB.BLOB;

The swagger file has below for the request body

"requestBody": {
          "content": {
            "application/pdf": {
              "schema": {
                "type": "string",
                "format": "binary"
              }
            }
          }
        }

Hi Naveena, I have to side with Chris

Please repost this in the ACE community: https://community.ibm.com/community/user/groups/community-home/digestviewer?communitykey=77544459-9fda-40da-ae0b-fc8c76f0ce18

That beeing said, I have setup mime emails with attachments by ussing multipart messages. But let's continue this in the proper community
