Trigger conditions
The Trigger tab lets you enable one or more condition cards, combined with OR logic (the survey fires when any enabled condition qualifies):- App event — one or more event keys your app fires with
MicroSurvey.trigger("checkout_completed"). - Screen visit — one or more screens, optionally with an “after N visits” threshold.
- App open — after a minimum number of app starts (cold launches by default; can include foreground resumes).
- Set delay — wait N seconds after a condition qualifies before showing.
Frequency and throttling
Below the conditions, the Trigger tab controls how often the survey can appear:- Minimum days between shows (
throttle_days, default 7) — the project-wide throttle window. See throttling. - Max shows per user — a hard cap on how many times this survey is ever
shown to one user, counted from the
impressionstable.
Confirming a trigger is wired
After shipping a version that fires a new key, watch for it to appear in the Auto-discovered list under Settings → [your app] → Events (or Screens). If nothing shows up after some production traffic, check:- The key in the dashboard matches the string in your app exactly (keys are case-sensitive; there’s no server-side normalisation).
MicroSurvey.identify()ran before the trigger.- The SDK is initialised (turn on
debug: truein development).
A survey only shows if throttling passes, a condition matches, the survey’s
response limit isn’t reached, audience filters pass, and the per-user show cap
isn’t hit — evaluated in that order. See
Triggers (concepts) for the full evaluation flow.
Targeting by audience
A trigger decides when a survey is evaluated; the Audience tab decides who qualifies. Audience filters run against two kinds of properties:- Device properties — auto-captured by the SDK on every
identify()(platform,app_version,locale,timezone,osVersion,sessionCount,daysSinceInstall,environment). No setup required. - User properties — custom, business-level attributes you send via
identify({ properties }), discovered into the User Properties registry.
plan equals "free" and daysSinceInstall ≥ 7.
Screen triggers
If you use screen tracking, the SDK reports visited screens (and firesscreen_viewed:<pathname>). Reported screens show up
under Settings → [your app] → Screens and in the project’s
Screen map view, where you approve the ones you want to
use as Screen visit trigger conditions.
