Have integrated the API both V1 and V3 since V3 does not have all the features of V1 (ie Sync contact).
But… I need to just check the status of a contact. I have the Actviecampaign ID calling
endpoint
xxx.api-us1.com/api/3/contacts/1212
the issue is that is VERY slow if you have an older contact with LOTS of tracking and automations.
Looking to see if there is an endpoint that I can just check if the contact is not getting our emails from a specific list.
We had to remove the feature from production since the API was taking up to 20 seconds to run some times.
thanks - FYI we can use the older API or the new V3 api - have access to both.
Thanks
Matt
