These are the specific failure types SendPromptly is built for. If the failure pattern is on this page, SendPromptly will detect it. If it is not, you may need a different tool.
Missing access after Stripe checkout
The customer paid, but the app did not unlock the feature, plan, workspace, or account.
The checkout.session.completed event was delivered. Your webhook returned 200. But the user’s account still shows the free tier. This is the most common post-payment support failure for SaaS teams — and it is completely invisible to Stripe’s delivery logs.
Relevant Stripe event: checkout.session.completed
Good fit for:
- Subscription SaaS with gated features
- Membership apps
- Gated dashboards and tooling
- Paid plan upgrades
Long-tail searches this solves: stripe checkout completed but access not granted, saas customer paid but no access, stripe webhook fired but account not upgraded
Related: checkout.session.completed not updating your app and customer paid but has no access.
Missing credits after invoice payment
Stripe says the invoice was paid, but your app did not add the credits.
Your handler accepted the invoice.paid event. The queue job ran. Somewhere between there and the credit column in your database, nothing happened — or the job crashed silently.
Relevant Stripe event: invoice.paid
Good fit for:
- Usage-credit SaaS
- AI credit products (token top-ups, generation credits)
- API quota systems
- Prepaid usage billing
Long-tail searches this solves: stripe invoice paid but credits not added, saas credits not applied after payment, ai credits missing after stripe checkout

Shopify orders paid but never applied in your app
A Shopify orders/paid webhook came in but your app never applied the intended business effect.
This is the same failure pattern as Stripe access failures, but in the Shopify context. The order is confirmed in Shopify. Your app accepted the webhook. But the effect — access unlock, credit grant, fulfillment trigger — never completed.
SendPromptly monitors Shopify flows with the same incident model as Stripe. No separate tooling required.
Relevant Shopify events: orders/paid, orders/fulfilled
Good fit for:
- Shopify apps that provision access or credits after purchase
- Digital goods sold via Shopify
- Membership or subscription products on Shopify
Long-tail searches this solves: shopify order paid but app not updated, shopify webhook not triggering fulfillment, shopify orders/paid incident detection
Related: Shopify orders/paid webhook not working.
Missing result after your app accepted the event
Stripe or Shopify says the event was delivered. Your app says it accepted the work. But no success or failure outcome ever comes back.
This is the quiet failure that hurts small teams most. The webhook returned 2xx, the queue job was dispatched, and nothing obvious broke on the payment provider side. But the effect never finished, so the customer still has the wrong app state until support gets involved.
SendPromptly detects this by waiting for a confirmed outcome after confirmed acceptance. If the timeout expires first, it opens a missing_result incident automatically.
Related: Stripe webhook delivered but nothing happened and how to monitor Stripe webhooks in production.
Good fit for:
- Queue-driven provisioning flows
- Jobs that call other internal services
- Effects that can time out or deadlock
- Teams that need an operator-safe recovery action
Silent background job failures after payment success
Your webhook accepted the event, but the queued job that applies the business effect failed later.
This is the hardest failure to catch. Your webhook returned 200. The payment provider considers the event delivered. Your queue worker picked up the job 40 seconds later — and it failed. Nothing flagged it. No alert fired.
This is why “webhook delivered” is not the same as “effect applied.”
SendPromptly catches this because it waits for your app to report the outcome — not just the acceptance. If the outcome does not arrive within the configured timeout, or arrives as a failure, an incident opens automatically.
Relevant events: checkout.session.completed, invoice.paid, orders/paid

Access revocation failures after cancellation or refund
The subscription was cancelled or a refund was processed, but your app never revoked access.
This is the mirror failure of missing-access-after-checkout. The customer’s account should have been downgraded or locked — and it was not. SendPromptly monitors revocation effects with the same timeout-and-incident model as grant effects.
Relevant Stripe events: customer.subscription.deleted, charge.refunded, charge.dispute.created
When SendPromptly is not the right fit
- You do not use Stripe or Shopify (additional providers are coming — contact us)
- You do not have custom app-side provisioning logic — Stripe Entitlements may be sufficient for simple feature gates
- You only need webhook delivery logging or forwarding
- You need a full entitlements or pricing control plane
- You need generic webhook routing or transformation across arbitrary providers
For webhook delivery and routing needs, Hookdeck or Svix are better fits.
