I have previously created and have been using one app to perform triggered sends with messageDefinitionSends. I now have the additional requirement of creating more sends that are defined under another business unit(we will call it busUnt2).
When I make the post to any trigger in busUnt2 https://www.exacttargetapis.com/messaging/v1/messageDefinitionSends/key:TEST_EXTERNAL_TRIGGER_ID/send?access_token=******r5afcz
I get a 404
error
{
"message": "Not Found",
"errorcode": 0,
"documentation": "https://code.docs.exacttarget.com/rest/errors/404"
}
I created a new app linked to busUnt2 to test and the trigger and it sends fine.
How can I configure my original app to send triggers built in any business unit?
