Node Reference

Every node available in Tandem workflows, grouped by category. Generated from the platform node registry.

Data

Retrieve, transform, and store data. Use these nodes to set variables, query databases, call integrations, invoke custom functions, or log events.

Invoke LambdaInvokes an AWS Lambda function IntegrationExecute an HTTP request (GET, POST, PUT, DELETE, PATCH) to a pre-configured external integration and optionally save response data to variables.Log EventLogs a custom event message for reporting via the events table.ResponseReturns a custom JSON response from the workflow execution.Set VariableCreate and save variables for this conversation.SharpenDB DELETERun a DELETE query on a table in SharpenDB.SharpenDB INSERTRun an INSERT query on a table in SharpenDB.SharpenDB SELECTRun a SELECT query on a table in SharpenDB.SharpenDB UPDATERun an UPDATE query on a table in SharpenDB.Create Zendesk TicketFiles a support ticket in a connected Zendesk account

Control Flow

Route and time your workflow. Branch with conditions and switches, schedule with time controls, or call subroutines.

ConditionEvaluate one or more conditions (with AND/OR workflow) against a variable and route to a true or false exit.Logic+ SubroutineExecute another Workflow+ as a subroutine within the current conversation, sharing the same conversation variables.LoopRun a block of nodes once for each element of an array.Loop BreakStop the enclosing Loop Group early and take its break exit.Loop GroupWrap a block of nodes and run it once for each element of an array.SwitchEvaluates a variable against a list of conditions and routes to the matching exit path. Similar to a switch/case statement.Time ControlRoute to different nodes on time-based conditions.Time DelayPause workflow execution for a specified duration before continuing.Try / CatchWrap a block of nodes so any unhandled failure inside routes to one shared recovery path.
