Everything after a scenario exists: running it, switching it on or off, and the run → inspect → drill-down
chain for a failure. Know trigger.kind (from scenario_get) before calling scenario_run — its behavior
depends on it entirely.
Ground rules. A 403 means the whole connection must be re-authorized with every permission — never one
tool. A content remark on a result is an instruction, not decoration. Say what you resolved an ambiguous
value to before the call that acts on it. The refusal contract and the rest: make-scenario-reference, when
something is refused or no tool seems to fit.
Running: scenario_run
- on-demand — runs with
inputskeyed by the declared input names and returns the declared outputs. - polling / scheduled — runs once now;
inputsare rejected, nothing is returned, the run lands in history. - webhook — nothing runs. The response hands back the webhook URL (or names the app event). Do not
report the scenario as "run"; have the user send a real request and check
scenario_execution_list.
An inactive scenario refuses with a pointer to scenario_activate — new scenarios start inactive. A
"pending" status means the run outlived the wait: check scenario_execution_get with the executionId, do
not assume failure. A rejected inputs key comes back naming the declared interface — read it rather than
guessing again. Inputs passed to a scenario with no interface are silently unused; a remark says so — relay it.
Activating and deactivating
Two separate tools, and an already-satisfied request is success, not an error. An activation refusal almost
always means a module still has a configuration error — scenario_get's per-module issues say which.
History: scenario_execution_list → scenario_execution_get
The list carries errorMessage inline for failed runs — often enough for "did it work, why not" without a
second call. A run started moments ago can lag the list by a few seconds (a remark says so; not data loss).
scenario_execution_get is for one run's outcome, outputs and consumption (credits and bytes — usage units,
not money); it has no per-module breakdown, so it answers "did it finish", not "which module broke". The
_show twins only when the user wants a rendered timeline or card.
Debugging a failed run: scenario_execution_inspect → scenario_execution_module_get
scenario_execution_inspect— overall status and error, plus every module that ran with invocation and error counts. Make records one error per run (the one that ended it); other failures show only aserrorCyclescounts. A warning run has no top-levelerrorat all —modules[].errorsis the only signal, so never report "no error found" as "nothing went wrong".scenario_execution_module_geton the suspect module and thecycleinspectreported (usually 1) — the real input and output that module saw. Never pick a cycle independently; a wrong cycle returns unrelated data with no warning.- Cross-check the current
configwithscenario_module_get— but first comparescenario_get'slastEditto the run'sstartedAt. If the scenario was edited after the run, what you read is not necessarily what ran; say so before attributing the bug.
…[truncated] marks a cut payload — text, not JSON to parse. A module with no downstream consumer
(ReturnData, WebhookRespond, a throw) always reports an empty output here even when correct; the scenario's
own output lives in scenario_execution_get's outputs.
A webhook that "isn't receiving data"
scenario_trigger_inspectfirst: it reportsqueueddeliveries — requests stored and waiting because the scenario is inactive, paused, or rate-limited. A non-zeroqueued.countis the answer to "I sent data and nothing happened" far more often than a broken mapping. It also shows the detected structure and recent deliveries, and with adeliveryIdone raw request.scenario_trigger_learnputs the webhook into learning mode: the next request is captured as the structure without running the scenario (safe on an active scenario). Give the user the URL and have them send one real request.
Withheld payloads (confidential or shared webhooks, bodies over 1 MB, binary) are replaced by a placeholder and explained in a remark — not "nothing arrived".
