Blocks

Block types you can add to a workflow, grouped like the builder palette.

Pick a type from the workflow builder palette. Shared rules (handles, variables, channels, nested bodies) are on the Workflows page; each block page covers Config for that type.

Types are grouped the same way as the palette (Output, Input, Context, Condition, Error, Loops, Module, Data Operations, Crypto, Utility, Chat, Table, Knowledge Base, File, Puppeteer, Schedule, User, Form Link, Share Agent, Notification, Gmail, Calendar, Drive, Sheets, Docs, Contacts, Meet, Tasks, WhatsApp, and more as they are documented). Search the list, or open a group to browse only that folder.

Types that need a connected service appear in the palette only when a matching connection exists.
