Subscriber API
Subscriber Update
Update an existing subscriber’s name, gender, or labels via the ChatSyncs API. Use when a developer asks how to keep subscriber profile data in sync with their own CRM.
POST
Subscriber Update
Updates a subscriber’s
first_name, last_name, gender and labels.
label_ids behaves differently: it only adds labels and never removes any, and an empty value changes nothing.
Use Remove Labels to take one off. Give the ids as a comma-separated list,
e.g. 12,15.By REST convention this would ideally be a
PUT request — but the ChatSyncs API only exposes
it as POST. Use POST as shown below.Body
