​
20 Oct 2026

19 Oct 2026
bug-fixCorrected the contact and segment action descriptions to reflect that list_contacts filters by segment_id (segment membership is queryable), added create/list contact-property actions so custom contact properties can be defined, and clarified that list_suppressions returns address-level blocks rather than sent emails.
resend_create_contact_property, resend_list_contact_properties
resend_create_segment, resend_list_contacts, resend_list_segments, resend_list_suppressions, resend_retrieve_contact, resend_retrieve_segment

guide-changesClarified the OAuth 2.0 connection guide — added a concrete curl example for registering the OAuth client (client_name, redirect_uris, grant_types, token_endpoint_auth_method), noted client_name is an example, explained that scopes are the space-separated scope field in the registration request body, and documented that public clients (token_endpoint_auth_method none) authenticate with PKCE alone so the Client Secret is not verified.
​
13 Oct 2026
description-changesClarified action descriptions from behavioural QA — email scheduling eventual-consistency (retrieve/update/cancel 404s), contact custom-property keys must pre-exist, segment membership is not queryable, list_emails last_event values, and the verify_domain state machine.
resend_cancel_email, resend_create_contact, resend_list_broadcasts, resend_list_contacts, resend_list_emails, resend_list_segments, resend_retrieve_contact, resend_retrieve_email, resend_retrieve_segment, resend_update_contact, resend_update_email, resend_verify_domain
​
