One approval covers the whole program and branches; credentials, activation and real tests have separate approvals.
Agent step
Full auto: tools normally set to Ask execute without asking. Off tools remain blocked.
Tool step identity
Account-owned connection or credential profile, selected per step; never a member's personal account.
Workspace
Workflows reach the common tree; protection blocks and system-entry rules still apply.
App functions
A manager's workflow save authorizes the apps used; callers share that access. See app access.
Rule — Workflows cannot pause for tool approval. Grant workflow agents only tools you trust to execute unattended.
Limits
Limit
Value or behaviour
Concurrent runs of one workflow
1; manual or scheduled starts during a run are refused. External deliveries queue.
Steps
20 across the complete workflow.
Declared inputs
20.
Nested conditions
8 levels.
Rules in one condition
10.
Prompt output fields
20.
Repeat cap
Required, 1–20 items; exceeding it fails the run.
Repeat execution
Reads and prompts parallel; writes and agents sequential. Item failures are collected by default.
Minute interval
5–1,440 minutes.
Hour interval
1–24 hours.
Recent deliveries
Latest 50; delivery data retained for 30 days.
Sample data
16,000 bytes.
Webhook request body
256,000 bytes.
Webhook rate
120 requests per minute per webhook.
Queued external deliveries
200 per workflow.
Automatic failures
Situation
Result
Failed scheduled, webhook or event run
Failure email to the workspace owner.
Third consecutive automatic failure
Workflow switches off; a final email reports the disablement. The UI shows Off after failures.
Failed manual run or user stop
Does not count toward automatic failures.
Successful run, including manual
Ends the failure streak.
Save or switch the workflow on
Restarts the failure count.
Account runs out of Sparks
Scheduled runs are skipped and incoming events dropped, without workflow failure emails.
For recovery, inspect the failed step in Runs, correct the workflow and use Switch back on, or enable it in Settings. Saving resets the count but does not itself reactivate a disabled workflow.
Costs and retry safety
Operation
What to account for
Prompt or agent work
Uses Sparks; each repeated agent item is a complete agent run.
Sample test
Real actions and normal Spark usage.
List's daily projection
Enabled schedules on active workflows only; external and manual traffic is excluded.
App write with an uncertain result
The change may have happened; inspect the app before retrying.
New app publication changes a function contract
Save the workflow again and review arguments and dependent outputs before retrying.
