Balsio

Deletes a personal channel for the integration user.

channels_delete

Removes the avatar of a bot integration.

integrations_avatar_delete

Deletes a message visible to integration user.

messages_delete

Deletes a scheduled message.

scheduled_messages_delete

Fetches a single channel visible to integration user.

channels_get

Fetches a single integration visible to the caller.

integrations_get

Fetches a single message visible to integration user.

messages_get

Fetches a single scheduled message.

scheduled_messages_get

Fetches a single thread visible to integration user. Each thread includes a `settings` object of boolean flags; every key except `is_sharing_enabled` is omitted when false, so treat missing keys as false. Key semantics (all defaults are false): `is_sharing_enabled: true` — thread has an active public share link; `is_email_digests_disabled: true` — the default ~5-minute batched digest emails stop; group threads get a weekly summary instead (one-on-one threads have no weekly digest); digest emails only go to members not reached by push; push notifications, including @mentions, are NOT affected; `is_participant_notifications_disabled: true` — membership system messages (joined/left/added/removed) are suppressed, along with the notifications those system messages would have generated; regular message notifications are not affected; `disable_participant_messaging: true` — only owners can post messages; `disable_participant_sub_thread_messaging: true` — only owners can post in this thread's sub-threads; `hide_participants: true` — non-owner viewers see only owners in `users`/`user_ids`, and `users_count` stays the true total; applies to regular top-level threads only (sub-threads and workspace-channel threads always return empty user fields and `users_count: 0`); `participants_can_add_users: true` — non-owner members may also add users. Full details: call capabilities_thread_types.

threads_get

Returns one-on-one vs group thread behavior, tool applicability, and the meaning of every key in the thread `settings` object.

capabilities_thread_types

Fetches a single user profile by id.

channels_list

Lists integrations visible to the caller.

integrations_list

Lists messages in a thread visible to integration user.

messages_list

Lists pending scheduled messages for integration user.

scheduled_messages_list

Lists threads for integration user (defaults to inbox channel). Pass parent_thread_id to list sub-threads of a given thread. Each thread includes a `settings` object of boolean flags; every key except `is_sharing_enabled` is omitted when false, so treat missing keys as false. Key semantics (all defaults are false): `is_sharing_enabled: true` — thread has an active public share link; `is_email_digests_disabled: true` — the default ~5-minute batched digest emails stop; group threads get a weekly summary instead (one-on-one threads have no weekly digest); digest emails only go to members not reached by push; push notifications, including @mentions, are NOT affected; `is_participant_notifications_disabled: true` — membership system messages (joined/left/added/removed) are suppressed, along with the notifications those system messages would have generated; regular message notifications are not affected; `disable_participant_messaging: true` — only owners can post messages; `disable_participant_sub_thread_messaging: true` — only owners can post in this thread's sub-threads; `hide_participants: true` — non-owner viewers see only owners in `users`/`user_ids`, and `users_count` stays the true total; applies to regular top-level threads only (sub-threads and workspace-channel threads always return empty user fields and `users_count: 0`); `participants_can_add_users: true` — non-owner members may also add users. Full details: call capabilities_thread_types.

threads_list

Returns the users for the given user ids.

users_list

Marks thread as read (or unread when message_id is null).

threads_mark_read

threads_users_roles_remove

Removes users from a group thread by user id (not supported for one-on-one threads).

threads_users_remove

Revokes an integration, permanently disabling its token.

integrations_revoke

Sends a scheduled message immediately.

scheduled_messages_send

Snoozes threads for integration user.

threads_snooze

Updates a personal channel for the integration user.

channels_update

Updates an active integration. A webhook_signing_secret is returned only when setting a webhook_url on an integration that has none yet; an existing secret is never rotated.

integrations_update

Updates a visible message. Use message.body for message text.

messages_update

Updates a scheduled message's delivery time or content.

scheduled_messages_update

threads_update

Updates settings of a group thread. Requires the owner role in the thread. Group threads only — one-on-one threads and sub-threads return an error. Only the provided keys are changed; omitted keys keep their current value. Each thread includes a `settings` object of boolean flags; every key except `is_sharing_enabled` is omitted when false, so treat missing keys as false. Key semantics (all defaults are false): `is_sharing_enabled: true` — thread has an active public share link; `is_email_digests_disabled: true` — the default ~5-minute batched digest emails stop; group threads get a weekly summary instead (one-on-one threads have no weekly digest); digest emails only go to members not reached by push; push notifications, including @mentions, are NOT affected; `is_participant_notifications_disabled: true` — membership system messages (joined/left/added/removed) are suppressed, along with the notifications those system messages would have generated; regular message notifications are not affected; `disable_participant_messaging: true` — only owners can post messages; `disable_participant_sub_thread_messaging: true` — only owners can post in this thread's sub-threads; `hide_participants: true` — non-owner viewers see only owners in `users`/`user_ids`, and `users_count` stays the true total; applies to regular top-level threads only (sub-threads and workspace-channel threads always return empty user fields and `users_count: 0`); `participants_can_add_users: true` — non-owner members may also add users.
