We send text messages from a campaign using an HTTPS post. We’d like to be able to set the text of the message as a parameter for the campaign, using something like a Campaign merge field (Campaign Merge Fields | Max Classic ).
However the HTTPS post configuration doesn’t give the option of Campaign merge fields, and entering ~Campaign.MergeFieldName~ doesn’t work either.
What could we use as a configurable field - that’s not specific to a contact - instead?
