Check it yourself

How do you check a Stripe integration before hiring anyone?

Stripe’s own docs warn that without signature verification an attacker could send fake webhook events to your endpoint, and that the same event can arrive more than once. These 3 checks need only your code.

CheckRun thisA pass looks like
Does the webhook check Stripe’s signature?grep -rnE "constructEvent|construct_event|parseEventNotification|parse_event_notification|Stripe-Signature" . --exclude-dir=node_modules --exclude-dir=.gitA match inside your own webhook route, called on the raw request body with the whsec_ signing secret. No match in your code means the route may accept fake events: look for another verification call before you rely on it.
Does it skip events it has already handled?grep -rnE "(evt|event|stripeEvent)(\.id|\[.id.\])|event_id" . --exclude-dir=node_modules --exclude-dir=.gitA match only starts the check: the handler should store each event ID it processes and return early on a repeat, so a retried event can’t grant access or send an email twice. Stripe adds that two separate events can describe the same change, so key on the object ID and event type as well.
Is a secret or restricted key anywhere it shouldn’t be?grep -rnE "[sr]k_(live|test)_[A-Za-z0-9]+" . --exclude-dir=node_modules --exclude-dir=.git --exclude-dir=distNo matches in committed code. A hit in a local .env file is fine if that file is never committed. Only the publishable pk_ key is safe in front-end code.

FAQ

Questions before you start

How much does it cost to hire a Stripe developer?

App369 publishes fixed prices: Stripe Billing Fix and Setup is $950, delivered 5 business days after repo access and a test-mode key arrive, and one named Stripe bug is an App Fix Ticket, a $450 diagnosis credited toward the $1,200 fix. Lemon.io’s hiring guide lists $60 to $140 an hour for mid-level and senior Stripe developers.

What do I need to hand over?

Access to the repository and a test-mode restricted API key with only the permissions the work needs. Simon never needs your live keys or your Stripe login.

Will you touch my live Stripe data?

No. All work runs in test mode, and the fix comes as a pull request with notes. Switching your account to live mode is a step you take yourself.

What isn’t included?

Stripe Connect marketplaces (quoted separately), tax registration or accounting advice, moving existing subscribers to new prices, switching your account to live mode, and calls, except paid consultations ($100 per 15 minutes, paid upfront).

Who does the work?

Simon Dziak, who founded App369, does the work himself, in writing by email. He built and runs the Stripe subscriptions, webhooks and payment links behind Workspace369’s billing.
