What is Retry Pattern?
Turkish: Retry Deseni
The Retry pattern handles transient network or service failures by repeating an operation with controlled timing and limits.
What is the Retry Pattern?
The Retry pattern repeats an operation after a temporary failure, following defined rules. If a payment provider fails to answer because of a brief network issue, the request may be attempted again after a short delay instead of being treated as permanently failed.
Retry is not meant to hide permanent errors. Wrong credentials, missing authorization, and invalid data will not become valid because the same request is sent again.
How Does it Work?
A reliable retry policy answers three questions:
- How many attempts? Unlimited retry can block queues and overload services.
- How long between attempts? Exponential backoff increases the wait after each failure.
- Which errors qualify? Responses such as
408,429,500,502, and503may be treated differently from validation errors.
Busy systems often add jitter so every client does not retry at the same moment. For write operations, idempotency keys help prevent duplicate payments, orders, or records.
Business Use
In API integrations, retry softens temporary interruptions in shipping label creation, payment status checks, accounting record delivery, and notification sending. Poorly configured retry can also overload the failing service and make the outage worse.
When failures continue, a circuit breaker can stop new calls for a while. Retry should therefore be designed together with monitoring, timeouts, and idempotency.
