Last update I've seen was from over a year ago: Exact Target Triggered Send using REST API with Data Extension

Only documentation I've found: https://code.exacttarget.com/apis-sdks/rest-api/v1/messaging/messageDefinitionSends.html

Is it still not possible to update a data extension during a triggered send call?

Is anyone still working on Exact Target?

  • Either an expired token or a comma at the end of a property caused a 400. Adding the data to subscriber attributes updated the data extension tied to the triggered send.

I'm not sure what data you want to update during a Triggered Send, however there are a couple of options for you:

  1. Select a "Triggered Send" Data Extension in the Subscriber Management section when configuring the Triggered Send. Note that this will only work with Triggered Send Data Extensions. Use the "Triggered Send" Data Extension template when creating the Data Extension
  2. Include UpdateDE(), UpsertDE() or InsertDE() AMPScript functions in your email template to update, upsert or insert records in a Data Extension at send time.
  • UpsertDE() doesn't work for us. Causes the send to error out. Added a function to look and see if the user is in the data extension, if user does exist -> UpdateDE(), else -> InsertDE(). That didn't work either.
