Fetch dynamic dropdown options for a step's field
Mirrors every ‘Refresh’ dropdown in the Studio Setup tab. Used to resolve human references like ‘#general’ or ‘Contacts module’ into the actual identifiers the action config requires. Always ask the user to pick from the response — never silently auto-select, even when only one option exists.
Per-app supported kind values:
- Slack:
channels,private_channels,users - Zoho CRM / Freshworks / Salesforce / Microsoft Dynamics:
modules,module_fields(params.module),records(params.module) - Airtable:
bases,tables(params.base_id),fields(params.base_id, table_id),records(params.base_id, table_id) - Apify:
actors,tasks - Gmail:
labels,messages - Google Calendar:
calendars,events(params.calendar_id) - Google Sheet:
spreadsheets,worksheets(params.spreadsheet_id),columns(params.spreadsheet_id, worksheet_title) - Notion:
databases,pages,database_properties(params.database_id),users - Twilio:
phone_numbers - Logic (builtin, no connection needed):
operators,joiners,delay_units - Tables (builtin, no connection needed):
tables,columns(params.table_id),operators,operators_for_type(params.type),aggregates,order_directions - Telegram: returns 422 — Bot API has no list endpoint
