Hi Christian, I am just looking at this now and trying to get it working.

It works fabulously well sending a HTML email from a Contact. I'm now trying to get it working with a VF Email Template on a Custom Object. It's just not doing the post to Chatter.

My coding skills are very limited so I am not sure how I debug the code to see where the problem lies. (The other actions on the process are working fine - eg it is actually sending the email).

For my inputs I have feedID = the Record ID of the custom object record I'm starting with. templateID is just static like your example - the ID of my VF Email Template. WhoID is the Contact ID (it is a lookup on the custom object). WhatID is the record ID of the custom object record I'm starting with - eg the record that renders the email template.

Is it something to do with email.getPlainTextBody()? Can a VF email be converted to Plain Text after it is rendered?

I suppose I should start with adding some debug statements and see where it is getting to.
And then adding another text segment with some static text to see if that posts.

Any other ideas?

Thank you for doing this, it is really going to help, once I can get it working.

OK, I put some debug statements in there, and this is all it's showing

[26]|DEBUG|ConnectApi.MessageBodyInput[messageSegments=(ConnectApi.TextSegmentInput[text=])]

I added a debug of

System.debug(email.getPlainTextBody());

and it just returned nothing.

The email is actually sending, and the rest of the process is working.

So I'm not sure where to turn next with it. I may have to just give up on this idea for now. So close, yet so far, because it works perfectly well for HTML emails.

@jodim -

Id contactId = '0033600000J3DZ7';
Id accountId = '0013600000QG6qS';
Id templateId = '00X36000001996H'
Messaging.SingleEmailMessage msg = Messaging.renderStoredEmailTemplate(templateId, contactId, accountId);
system.debug(msg.getPlainTextBody());
