feat: fire signup/checkout PostHog events from the backend - #277
Merged
Conversation
…the backend These 3 PostHog conversion events only fired client-side (useTracking.ts), so ad blockers and cut-short page unloads could drop them the same way they were dropping the GTM/ad-platform click IDs. Moves the PostHog side to the backend, same reliability rationale, same touchpoints already established for the click-id work: - user.signed_up: App\Actions\User\CreateUser, right after SyncUser is dispatched, gated on !is_invite. auth_provider derived from google_id/github_id presence, same values the frontend session-based flow used. - checkout.started: WelcomeController::storeReferralSource, alongside the existing WelcomeEvent::Referral capture, right before checkout starts. - checkout.completed: new TrackCheckoutCompleted job, dispatched from StripeEventListener::handleSubscriptionCreated (webhook-driven — more reliable than the old frontend flow, which depended on the user staying on billing/Processing.vue). Conversion value/currency/transaction_id read from the subscription webhook payload; transaction_id is the Stripe subscription id rather than the old Checkout Session id. Two new enums (UserEvent, CheckoutEvent) follow the existing per-domain PostHog event enum convention (WelcomeEvent, BillingEvent, PostEvent). useTracking.ts keeps its GTM dataLayer pushes (untouched, separate concern) and drops only the captureEvent(...) calls for these 3 events — PostHog already had CreateUser/WelcomeController/StripeEventListener as established backend touchpoints, so this reuses them instead of adding new infrastructure.
All 3 conversion events (sign_up, begin_checkout, purchase) now go to PostHog exclusively from the backend, and PostHog is the single source feeding Meta/Google/LinkedIn/etc ad destinations (not GTM). The dataLayer.push(...) calls in useTracking.ts had no consumer left, so the composable is now fully dead — deleted, along with its 3 call sites. Each call site's surrounding scaffolding that existed only to support the tracking call was simplified alongside it: ReferralSource.vue's submit() no longer needs the onStart/onError/onHttpException/onFinish dance (that was only there to gate trackBeginCheckout), and Processing.vue's completePurchase() no longer reads auth.plan just to pass it to trackPurchase(). datalayer.ts is untouched — it only pushes context variables (user name/ email, account/workspace name) that Crisp reads, not events.
…d / trial.converted checkout.completed used to fire on every customer.subscription.created regardless of the resulting status, conflating two different business events: a card-required trial starting (status trialing, no charge yet) and an immediate paid subscription starting (status active — first-month coupon or no trial). These are now separate PostHog events: - trial.started: subscription created with status trialing. No conversion_value (nothing has been charged) — carries trial_ends_at instead. - checkout.completed: subscription created with status active (coupon or immediate full-price checkout) — unchanged behavior, still carries conversion_value/currency/transaction_id. - trial.converted (new): the trial's first successful charge, detected on customer.subscription.updated via Stripe's own previous_attributes.status transitioning from trialing to active. This is the Stripe-recommended way to detect what changed in an .updated webhook, and doesn't depend on our own DB write ordering — Cashier's WebhookController dispatches WebhookReceived before it syncs the local subscription row, so trusting our own stripe_status here would be fragile. TrackCheckoutCompleted and the new TrackTrialConverted share their plan/interval/persona/conversion_* property computation via App\Support\StripeSubscriptionConversion (same shape, two different moments in the billing lifecycle) instead of duplicating it. Deliberately out of scope per product decision: trial-expired-without- converting tracking (signups minus conversions already gives that number), and the async-payment-method incomplete status edge case (card/debit only, Stripe Checkout resolves 3DS inline before redirecting back — incomplete essentially can't happen in this flow).
…nput array $user already has google_id/github_id populated (they were passed straight into User::create() a few lines above), so re-reading them from $data was redundant — same information, extra indirection.
…f-hosted registration gate Found while reviewing why CreateUser's `! $isInviteRegistration` PostHog gate never actually excluded anyone via Google/GitHub — because is_invite was always false for OAuth registrations, regardless of whether the person arrived from an invite link. Two real, pre-existing bugs: 1. SocialLogin.vue's Google/GitHub buttons linked to the OAuth redirect routes with no query params at all — invite, redirect and email were silently dropped the moment someone clicked "Sign up with Google" instead of using the email form. The person got a brand-new independent account + workspace instead of joining the inviter's account; the invite itself sat unaccepted with zero feedback. 2. /auth/google/redirect and /auth/github/redirect were never wrapped in the `registration.enabled` middleware that gates /register in self-hosted mode — so self-hosted installs could be signed up into via OAuth with no invite at all, bypassing the intended lock. Fix: - New PreservesInviteRedirect trait carries `invite`/`redirect` across the OAuth round-trip via session (PreservesAttributionParameters' pattern, but kept separate since this isn't marketing data). - SocialLogin.vue now forwards `redirect`/`invite` from its parent page onto the Google/GitHub links; Register.vue and Login.vue pass their props through. - registerNewUser() now passes the same `is_invite` semantics RegisterRequest already uses for the email flow, and both registerNewUser()/loginExistingUser() honor the pending redirect (same target AcceptInvite.vue already sends the email flow to), so accepting via OAuth now lands back on the invite page authenticated, exactly like email/password does — no auto-accept, same explicit-consent UX. - The self-hosted gate can only be enforced in registerNewUser() (after the callback resolves an identity) since /redirect is shared with login and can't tell new vs. returning users apart beforehand. New App\Models\Invite::fromId() (safe UUID-checked lookup) and App\Support\SafeInternalRedirect (same-app-path-only check) replace duplicated inline logic in RegisterRequest, RegisteredUserController and AuthenticatedSessionController, and are now shared with the OAuth path too.
… invite redirect Never trust a redirect URL from the client. Login/register/OAuth now only accept an invite id (already validated via Invite::fromId()) and derive the return-to-invite route server-side, eliminating the open-redirect surface instead of validating around it.
Str::isNotEmpty()/toString() replace manual is_string/empty checks. Also cut oversized inline comments down to one line each.
Mirrors the existing Google coverage — GitHubController has the same invite-completion and self-hosted-gate logic but only Google had tests for it.
TrackCheckoutCompleted, TrackTrialStarted, and TrackTrialConverted shared near-identical boilerplate (guard clause, capture call, tries/timeout). Extracted AbstractTrackStripeSubscriptionEvent so each job only declares its event name and properties. StripeSubscriptionConversion now exposes baseProperties() (plan_name/interval/persona) shared by all three, with propertiesFor() adding conversion_* on top for the two charge-backed events.
currentStatus()/wasTrialing()/isNowActive() replace inline data_get() comparisons in trackSubscriptionStart() and trackTrialConversion().
Persona is already set as a person property via identify() during onboarding, so it is joinable on every event without repeating it — sending it again on every billing capture was dead weight.
PostHogService::capture() already injects 'plan' from $account when an account is passed — the manual key was silently overwritten by the identical value.
Lets capture()/identify()/groupIdentify() be verified from laravel.log during local testing (e.g. signup, invite flows) without a real PostHog API key configured. Logging is independent of isEnabled() — the actual dispatch to PostHog stays gated on it as before.
- Fire checkout.started only after the price-ID guard, not before it, so a misconfigured plan can't record a phantom checkout.started for a checkout that never starts (WelcomeController). - Reorder OAuth registerNewUser() so the destructive session pull of attribution parameters happens after the self-hosted invite gate, not before — a rejected attempt no longer discards UTM/click-id attribution (GoogleController, GitHubController). - Delete the SignupSuccess page/controller/route entirely: it only ever displayed a 5s cosmetic transition before redirecting home, its tracking call was already removed, and app.calendar's own middleware handles onboarding redirects regardless of entry point. The 3 post-registration redirects now go straight to app.welcome (was silently dropped to app.home in an earlier pass of this cleanup — welcome is correct, that was the whole point of the intermediate page). - Remove dead code left behind by the useTracking.ts removal: unused persona/conversion props (and the Stripe API call in BillingController that only existed to populate them), unused auth_provider session flash across 3 controllers, unused captureEvent() export in posthog.ts, and unused RegisterRequest::isInviteRegistration(). - Add missing test coverage: login with a valid/unknown invite param (AuthenticatedSessionController's invite-redirect branch had zero coverage), and a regression test locking in the checkout.started ordering fix.
…eak, null interval bug - Reject OAuth registration (Google/GitHub) when the invite's email doesn't match the authenticated provider account's email, mirroring the check RegisterRequest already enforces for the web form. Previously an invite for one email could be completed by signing in with a different Google/ GitHub account, leaving a permanently workspace-less orphaned account (AcceptInvite's WrongEmail path never runs the shell-account cleanup, since that only fires on Result::Accepted). - Fix PreservesInvite::storeInvite() to always overwrite the session value (matching PreservesAttributionParameters, which it claimed to mirror but didn't). It previously only wrote when the invite param was present, so a stale invite id from an aborted OAuth attempt could leak into a later, unrelated login/registration in the same session. - Fix StripeSubscriptionConversion::baseProperties() mislabeling a conversion as 'yearly' when both the webhook price id and the plan's stripe_yearly_price_id are null (null === null) — now requires the plan price id to be non-null before comparing, matching the equivalent guard in App\Support\BillingCycle::intervalMonths(). - Remove the fully dead fromCheckout/Cache::add mechanism in BillingController::processing() — its only consumer (the frontend trackPurchase call) was already deleted earlier in this PR. - Drop the unused owner eager-load in AbstractTrackStripeSubscriptionEvent and TrackBilling — neither reads $account->owner, only owner_id.
…e via container - CreateInvite::execute() now lowercases the invite email before storing it. Invite acceptance/decline/registration all compare it verbatim against User.email (itself always lowercase), so a mismatched-case invite created before this fix could otherwise never be accepted by its own recipient. - CreateUser::execute() resolves PostHogService from the container instead of `new PostHogService`, matching the DI pattern used by every other PostHog call site added in this PR.
…der toggles server-side; count past_due recovery as a trial conversion - EnsureRegistrationEnabled, GoogleController, and GitHubController now require the invite param to resolve to a real Invite (Invite::fromId()) instead of just checking presence. Previously any random string/UUID satisfied the self-hosted "invite required" gate and produced a fully functional account with its own workspace, defeating the restriction entirely. - google_auth_enabled/github_auth_enabled were only ever read on the frontend to show/hide the login button — the actual OAuth routes (GoogleController/GitHubController::redirect(), and the settings connect-provider endpoint) had no backend check, so a disabled provider could still be used end-to-end by hitting the URL directly. Both are now gated with abort_unless(..., 404). The settings Authentication page also stops rendering a "Connect" button for a disabled, not-yet-connected provider. - StripeEventListener::trackTrialConversion now also fires trial.converted on a past_due -> active recovery (a trial's first charge attempt failing and then succeeding on retry), not just the immediate trialing -> active transition. Guarded by trial_end being set so a long-time paying customer's unrelated payment-method recovery is never miscounted as a trial conversion.
google/github were each hand-checked against config("trypost.{provider}_auth_enabled")
independently in GoogleController, GitHubController, AuthenticationController
(3 different shapes: hardcoded config key, in_array against a private const
array, and a duplicated string list for labels), plus a fourth copy of the
enabled flags in HandleInertiaRequests. Adding a provider meant touching all
of them by hand.
App\Enums\Auth\SocialAuthProvider is now the single source of truth: cases()
replaces the PROVIDERS const array everywhere it was iterated, label()
replaces the hand-written label map, and isEnabled() replaces every direct
config() call. AuthenticationController::connectProvider() collapses its two
abort_unless checks into one via tryFrom()?->isEnabled().
…nDisconnect()
The same "{$provider}_id" dynamic-property pattern was hand-written in three
places in AuthenticationController (disconnectProvider's column lookup,
getConnectedAccounts' connected flag, canDisconnect's loop). User::isConnectedTo()
centralizes it, and canDisconnect() now reads as a single collection pipeline
("is there some other connected provider or a password") instead of a
counter-then-compare loop. disconnectProvider() also switches to the
already-resolved SocialAuthProvider throughout instead of re-deriving from
the raw string, and its flash message now uses ->label() instead of
ucfirst($provider) (which mis-cased "github" as "Github" instead of "GitHub").
REDIRECT_DELAY_MS existed to give a client-side PostHog/ad-pixel capture call time to flush before navigating away. That call was removed earlier in this PR (checkout.completed now fires from the Stripe webhook, server-side, independent of this page), so the delay had nothing left to wait for — navigate immediately once the poll confirms subscriptionActive.
…e' | 'github' union
GoogleController/GitHubController flash OAuth failures (wrong invite email,
GitHub email unavailable) via redirect()->route('login')->withErrors([...]).
That lands as page.props.errors (Inertia's page-level error bag), not as
the <Form> component's own local submission errors — so the InputError
bound to errors.email never showed it, silently swallowing the redirect's
whole point. Falls back to usePageErrors() (already used elsewhere in the
app for this exact scenario) when the form's own errors are empty.
Pest feature tests can only assert session state, not what actually renders — this drives a real browser through the OAuth invite-email-mismatch redirect and asserts the error text is visible on /login. Confirmed it fails without the Login.vue fix (assertSee fails at the expected point) and passes with it restored.
…pre-checks signup, trial, and billing events never reached PostHogService::capture() locally because CreateUser and StripeEventListener short-circuited on isEnabled() before the local-logging path in capture() could run. Added shouldTrack() (isEnabled() || local environment) and applied it at every dispatch/handle guard in the chain, while the real API call in SendEvent stays gated on isEnabled() alone so production behavior is unchanged.
…er unrelated payment retry convertedFromTrial() used trial_end being non-null to detect a past_due -> active recovery as a trial conversion, but Stripe never clears trial_end once set, so the guard could never actually exclude a long-time paying customer's unrelated card-decline recovery months later — it would fire trial.converted again, double-counting conversion_value. Now compares the subscription item's current_period_start against trial_end, which only match for the trial's own first billing period. Also reverts the CreateInvite.php Str::lower() normalization added earlier in this branch — invite emails are stored and compared as submitted, with no manual casing normalization anywhere. Adds a diagnostic log in trackTrialConversion() (unconditional, not gated on shouldTrack()) to verify this against a real Stripe webhook payload via a test-clock walkthrough.
…ctually exists; drop diagnostic logging WelcomeController::storeReferralSource captured checkout.started before calling StartSubscriptionCheckout::redirect(), so a failure creating the Stripe session (e.g. the coupon/promo-code conflict ConfigureSubscription Checkout throws on, or any Stripe API error) still left a false-positive conversion event in PostHog. redirect() now runs first; the capture only fires once the checkout session was actually created. Also removes the unconditional Log::info() added to trackTrialConversion() for the manual Stripe test-clock verification — the current_period_start fix it was added to confirm has now been validated against a real webhook payload, so it's no longer needed and shouldn't keep logging on every production subscription.updated event.
…sInvite GoogleController and GitHubController each duplicated the same self-hosted registration gate and invite-email-mismatch check verbatim. Moved both into resolveInviteForRegistration() and inviteEmailMismatchRedirect() on the shared PreservesInvite trait so a future OAuth provider (or an edit to one controller) can't silently drift from the other on these security-relevant checks.

Summary
user.signed_up,checkout.started,checkout.completedonly fired client-side (useTracking.ts→posthog-js) — ad blockers and cut-short page unloads could drop them, same reliability problem the ad-platform click-id work (#276) fixed. This moves the PostHog side to the backend, and splitscheckout.completedinto three distinct billing-lifecycle events since it was firing on every subscription creation regardless of whether the customer was actually charged. It also fixes an unrelated bug found along the way: OAuth signups were silently dropping pending invites.Signup/checkout events → backend
