What value should I use for
I have seen some answers. Which is suggesting, we can set either
Email Address or
Subscriber Key based on your salesforce configuration?
How can I determine, which
SendableSubscriberField is enabled in my salesforce configuration?
While I pass
Subscriber Key in
SendableSubscriberField salesforce throws the following error:
The SendableSubscriberField cannot be SubscriberKey because the SUBSCRIBER_KEY business rule has not been turned on.
So, How to check SUBSCRIBER_KEY business rule has been turned on using SOAP API?
Thanks in advance!
