I'll set up webhooks for event exchange between services

I set up webhooks so your services learn about each other's events instantly, not once every few minutes on a polling schedule. When a client pays for an order, leaves a request, or cancels a subscription, the receiving system gets a signed HTTP request within seconds — and the process reacts immediately, without extra server load and without delays from periodic checks.

I work in both directions: I set up sending events from your platform to external CRMs, payment systems, or internal services, as well as receiving webhooks from third-party platforms into your backend. I design the structure of the payload, add signature verification so you can trust every incoming call, build retry logic with increasing delays in case the recipient is temporarily unavailable, and set up logging so failed deliveries are visible, not silently lost.

I also handle deduplication separately: systems sometimes send the same event twice, so I add idempotency keys so a retry doesn't create a duplicate entry in the database or duplicate charges for the customer. Before delivery, I test the pipeline on real and corrupted events and leave documentation on endpoints and secrets so the team can maintain everything independently.

What's included in the work:
— design of endpoints and signature verification;
— retry strategy for delivery failures;
— deduplication and idempotent processing;
— logging of missed events;
— documentation for your team.
