There are three pieces of data (From Name, From Email and HTML Body) we have to screen scrape from the UI as they are not in the API.

We screen scrape the data out from https://podX.ibmmarketingcloud.com/ux/#/sentMailing/[MAILINGID], to use in our in-house reporting platform. We use to use https://engageX.silverpop.com/mailingsSummary.do?action=displayHtmlBody&mailingId=[MAILINGID] which does still work.

Add From Name, From Email and HTML Body to GetSentMailingsForOrg

It's unclear if this will be possible once IBM ID is required, as we use the jsessionid to login.
