Flow Steps

Add a step to a flow (trigger as step 1, actions as step 2+)

Creates either a trigger (only one allowed, must be step 1) or an action. The server picks the position: by default appends to the end, but insert_after_step_uuid puts it mid-chain (downstream steps shift up + their {{stepN.field}} references are rewritten), and parent_step_uuid + branch_key makes it a child of an if_condition branch.

Validation rules:

kind=trigger → flow must not already have a trigger; app must support_trigger=true.
kind=action → flow must already have a trigger; app must support_action=true.
app.category=connect → app_connection_uuid is required and must belong to this tenant + this app.
app.category=builtin → app_connection_uuid must be null.
Agents app actions → agent_uuid required.
Branch child → parent_step_uuid must point to an if_condition step.

Cannot edit a deployed flow — returns 409 unless you POST /undeploy first.

data

object

One step of a flow. The first step in a flow is always a trigger (kind=trigger); subsequent steps are actions. Branch children (under an if_condition) appear flat in the parent flow's steps[] with parent_step_uuid + branch_key populated.
