- apply_actionsValidate and apply a batch of flow-builder actions — the single write path for editing flows, blocks, variables, broadcasts, sequences, and folders. Call this directly; a separate validate_actions ca…
- create_applicationCreate a new application (workspace) owned by the caller. Requires a personal API key (usr_...) — application-scoped keys cannot create applications. Seeds default flows unless skipDefaultFlows is tr…
- create_contactCreate a contact manually — for imports or externally-sourced audiences; contacts who message a bot are created automatically. Requires the manage_broadcasts permission. platformId must be unique wit…
- create_follow_up_taskCreate a follow-up reminder for a person to get back to a contact. Creates persistent state and is NOT idempotent: calling it twice creates two reminders. Nothing is sent when it comes due — it is a …
- deploy_applicationPublish the workspace to its bots — the API equivalent of the dashboard's Deploy button. This is the step that makes edits live. apply_actions writes to the DRAFT graph. Until this runs the connected…
- execute_telegram_operationSubmit one supported read operation on the connected telegram_mtproto account. Call list_telegram_operations for the input schema. Returns a requestId; poll get_telegram_operation until completed, er…
- get_action_schemaReturn the action-authoring contract that apply_actions batches are validated against. Read-only, needs no API key. Called with NO arguments it returns a compact INDEX: every creatable block type, ac…
- get_application_contextReturn the full application-level automation context in one read-only call: every flow (with folders), connected bots, variables, sequences, and operations. This is the broad orientation call — prefe…
- get_block_detailsReturn the complete contents of one block: block data, action configs, HTTP request bodies, custom-code files, triggers, menu payloads, and media paths. Read-only. This is the heaviest read in the AP…
- get_broadcast_analyticsReturn engagement analytics for a broadcast: delivery breakdown by status plus per-message-block sent and clicked counts for its flow, over an optional date window. Read-only. Sent counts reflect mes…
- get_broadcast_detailsReturn full details for a single broadcast: status, schedule, recurrence rule, linked flow, and delivery breakdown by status. Read-only. Call list_broadcasts first to find the broadcastId. For per-me…
- get_contactReturn one contact's full profile plus every contact-variable value stored for them. Read-only. Values may hold personal data; variables of type SECRET are always redacted. Call list_contacts first t…
- get_contact_activityReturn one contact's engagement history: goals they achieved and buttons they clicked, newest first, plus all-time goal totals. Read-only. This is the per-contact companion to get_broadcast_analytics…
- get_design_guidelinesReturn the flow-design rules that validation does NOT enforce: when to split a branch into its own flow, how navigation and menus must be wired, and worked examples. Read-only, takes no arguments, an…
- get_flow_analyticsMeasure how NAMED flows are actually used over the last 30 days: how many contacts entered each one, where inside it they stop (per block, with the stop RATE), how many were answered by a human agent…
- get_flow_contextReturn one flow's graph topology: its blocks, how they link, and a short summary per block. Read-only. Deliberately omits block data and action configs to stay cheap — once you know which block matte…
- get_flow_exampleReturn one reusable flow example by id, optionally with a complete action batch you can adapt and pass to apply_actions. Read-only, needs no API key. Call search_flow_examples first to find the id.
- get_funnel_analyticsReturn the measured conversion funnels of the workspace's ENTRY flows over the last 30 days, busiest first: how many new contacts entered, which blocks they reached, the share who stop at each block,…
- get_module_catalogReturn a compact index of both installed and available marketplace modules, with each module's key, versions, description, actions, and triggers. Read-only. Start here when you need a capability the …
- get_module_detailsReturn everything needed to use one module: action input fields and their types, trigger configuration, manual setup fields (credentials an operator must fill in the dashboard), and references to alr…
- get_pulse_itemReturn one Pulse item in full: the measured evidence, the ids of the conversations and execution-log rows behind it, and the change Apply would build if the item carries one. Read-only. Call list_pul…
- get_telegram_operationRead a Telegram operation status and result using its requestId and the same applicationId/botId used for submission. Requires manage_broadcasts for the owning application. Poll every two seconds. Re…
- get_variable_contextSearch variable definitions by scope and keyword. Read-only. Returns { variables, total, returned, truncated } — compare returned against total to detect a cut-off result set and re-call with a highe…
- get_website_importStatus of a website import started by import_website_knowledge or an import_website_into_knowledge_base action: stage, progress, counters, warnings and the pages that were not imported. Read-only. Po…
- get_workspace_summaryReturn a compact application, flow, sequence, operation, and bot summary — the cheapest way to orient in a workspace. Read-only, no side effects. Deliberately omits variables and full flow graphs: us…
- import_website_knowledgeCrawl a website into a knowledge base so an AI_TOOL_ROUTER can answer from it. Creates a new base (named after the host) unless knowledgeBaseId is given. Honours robots.txt, skips junk and duplicate …
- install_moduleInstall an exact marketplace module version into an application and create any missing installed-template actions. Requires the manage_automation permission. Call get_module_catalog first to select t…
- list_applicationsList the applications this API key can access, with the caller role and the permissions it grants. Start here when using a personal API key (usr_...): every other tool needs an explicit applicationId…
- list_broadcastsList broadcasts in the application with status, schedule, and delivery counts. Read-only. Filters combine as AND. Note that delivery counts report messages attempted, not confirmed deliveries. Use ge…
- list_contact_tagsList the contact tags in use in the application (or one bot) with how many contacts carry each, most-used first. Read-only. This is the attribution view: UTM tags ("utm: <slug>", set by ?start=utm--<…
- list_contactsList and search contacts in the application, paginated, newest first. Read-only. Filters combine as AND; search matches name, username, email, phone, and platformId; `tags` / `tagIds` keep only conta…
- list_event_contactsThe reverse lookup: which contacts triggered one analytics event — achieved a goal (kind GOAL + goalKey), clicked a button (BUTTON_CLICK + blockId, optionally buttonId/buttonIndex), were sent a block…
- list_follow_up_tasksList follow-up tasks — reminders for a person to get back to a contact. Read-only, ordered by due time so overdue work comes first. A follow-up sends nothing by itself. Scopes: `mine` needs a persona…
- list_pulse_itemsList Pulse items — the workspace attention queue. Two kinds: `attention` is an observed problem a detector found (failing flows, a failed broadcast, an unsubscribe spike), `recommendation` is a propo…
- list_telegram_operationsDiscover supported Telegram MTProto account operations, input schemas, permissions and limits. Requires manage_broadcasts. All current operations read public data; this catalog does not connect to Te…
- list_watched_groupsList the group/channel chats a telegram_mtproto userbot monitors. Read-only. The watched list is the single source of truth for which chats the userbot processes: messages from unlisted group/channel…
- query_flow_logsRead the bot execution log (flow_execution_log) — the record of what the runtime actually did, and the only place that separates "the action ran" from "the action produced output". Read-only; require…
- read_messagesRead the message transcript: what users sent the bot and what the bot sent back, newest first. Source is the runtime's own message ledger, written by the bot as it handled each turn — inbound message…
- run_flow_autotestRuns deterministic behavioural tests against flows that are ALREADY applied (compiles them to an AST and simulates a user). Call after apply_actions to verify a build; read `summary` and the failed c…
- search_flow_examplesSearch the library of reusable flow examples covering common business cases (lead capture, onboarding, payments, reminders). Read-only, needs no API key. Returns compact matches — id, title, summary,…
- search_flowsFind every flow and block whose contents contain a keyword. Read-only. Searches message text and its translations, button labels and URLs, action names and configs, action input/output field paths an…
- send_flow_to_contactsRun an EXISTING interactive flow for each listed contact right now, outside any trigger — as if each of them had just triggered it. Use it when the WHOLE message is the flow — its first block's text,…
- send_messageSend a message to ONE contact right now, outside any flow. For reaching many contacts use a broadcast instead. Target the contact with contactId (globally unique — preferred), or with platformId (the…
- set_watched_groupsReplace a telegram_mtproto userbot's watched-groups list — the chats it monitors. Requires the manage_settings permission. SET semantics: send the COMPLETE desired list every time (call list_watched_…
- sync_dialog_contactsImport a telegram_mtproto userbot's existing chats as contacts — DM partners, groups, and channels — so everything the account already talks to becomes a valid send_message target without waiting for…
- update_applicationUpdate application-level settings (name, active state, default language, incoming-message behavior). Requires the manage_settings permission in that application. Only the fields you pass are changed;…
- update_contactUpdate a contact's profile fields and/or contact-variable values. Requires the manage_broadcasts permission. Only the fields you pass are changed — omitted fields keep their current value — so the ca…
- update_follow_up_taskClose, reopen, snooze, or reschedule one follow-up task. Completing it records that a person handled the reminder — it does not message the contact. Snoozing moves the due time too, so the task reapp…
- update_pulse_itemChange one Pulse item's state. Every action changes the queue for the WHOLE workspace — an item belongs to the workspace, not to whoever called the tool, so dismissing a recommendation hides it from …
- validate_actionsDry-run validation of a proposed batch of flow-builder actions. Mutates nothing and is safe to repeat. OPTIONAL: apply_actions runs this exact validation itself and applies nothing when invalid, so c…
