I will stop stripe duplicate charges with webhook idempotency


Sobre este Serviço
Seeing duplicate charges or duplicate invoices in Stripe? This is usually caused by webhook retries, missing idempotency, or non-atomic processing.
I will implement deterministic idempotency (evt_ + business keys), safe retry handling, and logging so each action happens once and only once.
Common problems I fix:
Duplicate charges / double billing
Duplicate invoice posting or fulfillment
Webhook retries causing repeated side effects
Race conditions / concurrency issues around payment events
What you get:
Root-cause analysis from Stripe event IDs and logs
Clean, testable fix (code/config)
Verification steps + short prevention checklist
Not included: UI work, full rewrites, open-ended consulting.
To start: share evt_/ch_/pi_/in_ IDs, webhook events list, and logs (secrets removed).

Perguntas frequentes
What do you need to start?
Please share Stripe IDs (evt_/ch_/pi_/in_), timestamp of the duplicates, and webhook/log screenshots (remove secrets). If possible, provide test mode or restricted access.
Do you need full admin access to Stripe?
No. Restricted access is usually enough. Live access only if strictly required to reproduce/verify.
Can you fix duplicate charges without code access?
Sometimes I can identify the cause, but a reliable fix usually requires access to the webhook handler / backend logic that processes Stripe events.
What causes duplicate charges most often?
Webhook retries, missing idempotency, processing the same event twice, race conditions/concurrency, or retrying non-idempotent operations.
Do you support WooCommerce/Shopify plugins?
Only if the issue is reproducible and you can provide staging access or clear logs. Plugin debugging outside Stripe/webhook scope is not included.
Will you redesign my checkout or UI?
No. This gig is backend reliability only (webhooks, idempotency, retries, logging).
Do you rebuild my whole billing system?
No. I deliver targeted fixes + minimal hardening for the defined flow. Full rewrites are out of scope.
Do you guarantee duplicates will never happen again?
I guarantee idempotency and safe retry handling for the specific flow/event types we implement and verify. New flows or unhandled event types may require an additional task.
