Stripe integration engineering
We build Stripe integrations where money movement is auditable: signature-verified idempotent webhook consumers, subscription and entitlement lifecycle wiring, metered usage reporting, and payout reconciliation that attributes every variance line to fee, refund, or dispute.
Request a scoping callStripe's API is excellent; most defects live in the integration around it. Duplicate webhook deliveries, half-applied subscription changes, and reconciliation done in a spreadsheet are the recurring three.
We verify before parsing, persist raw events under a unique key, process asynchronously, and reconcile provider state against our own on a schedule.
What we build against in Stripe
Payments and Billing APIs
Customers, subscriptions, prices, invoices, and usage records, written with idempotency keys on every mutating call.
Webhooks
Signature verification on the raw body, unique-constrained event storage, asynchronous processing, and a replayable event log.
Reporting and payout data
Balance transactions and payout reports reconciled against the internal ledger with variance attribution.
Work we are typically engaged for
Subscription and entitlement lifecycle
Plan changes, proration, dunning, and cancellation reflected in product entitlement with a reversal path for every action.
Metered and hybrid pricing
Usage aggregated in an immutable metering core and reported to Stripe per period, with soft limits warned before hard enforcement.
Payout reconciliation
Payout batches matched to internal transactions with every variance attributed to fee, refund, dispute, or unmatched for human review.
What every build includes
- Signature verification on the raw request body, before parsing.
- Idempotency keys on every mutating API call and unique-constrained event storage.
- Asynchronous processing with bounded retries and an inspectable dead-letter store.
- Scheduled reconciliation between provider state and the internal ledger.
Stripe integration questions
How do you prevent duplicate charges or double invoicing with Stripe?
Idempotency keys on every mutating call, unique-constrained webhook event storage, and upsert-based downstream effects, verified with deliberate fault-injection runs.
Can Stripe handle usage-based pricing for a B2B product?
Yes, with a metering core you own that aggregates usage into immutable periods and reports it to Stripe. The aggregation and period-close discipline belong in your system.
