Idempotency
Idempotency is the property of an operation that produces the same result whether it is executed once or multiple times. In AI automation systems, idempotent API calls and message handlers ensure that retries after network failures or timeouts do not cause duplicate actions — duplicate payments, duplicate records, or duplicate AI-triggered workflows.
Idempotency is implemented through idempotency keys: unique identifiers sent with each API request that the server uses to deduplicate retries. For AI agents operating in agentic loops with tool calls that modify state (write to database, send email, initiate payment), non-idempotent operations are a production reliability risk. Design tool calls to be idempotent by default; use idempotency keys for external API calls.
Idempotency in practice
Where it bites in business automation: an agent that retries after a timeout and books the same appointment twice, or a webhook delivered twice that creates two invoices. The fix is a unique key per business event, stored with the result, and a check before any action that changes state. That check belongs in any AI workflow automation that writes to other systems.
