Hi,
Is there an endpoint to opt-in contacts? I tried it from the docs: https://api.infusionsoft.com/crm/rest/v2/emailAddresses/{email}/status, but keap didn’t allow. Opt-Out: Admin is not allowed to be changed via API?
Yes, the PATCH endpoint (/crm/rest/v2/emailAddresses/{email}/status), but even with that you cannot change a contact from Opt-Out (unsubscribed) back to Opt-In via API. Keap locks true unsubscribes for compliance reasons, so any attempt to override that status is blocked.
