It’s part of the string you get here in the officerList response.
"links" : {
"officer" : {
"appointments" : "string"
}
}
items[].links.officer.appointments (Link to the officer appointment resource that this appointment is associated with).
Mark, this has come up a couple of times recently. The appointmentList call requires an officer_id as the part of the call. This ID is part of the string returned by the the officerList call. But it doesn’t appear outside of that string and is not explicitly referred to as the “officer_id” in any of the documentation or resources… which makes things a bit confusing!
