Password Reset Email API Request Timeout Guide (2 Ownership Guards)
Short answer: issue one reset token, record that decision atomically, and let retries reuse the same send operation. A timeout is an unknown result, not permission to mint another token or fire another email. For a fintech contact flow, keep the reset template owned by the authentication path; the support router may classify the contact and select a queue, but it should never become a second…
The guide explains best practices for handling password reset email API requests, particularly in situations where requests may time out. It emphasizes using a single reset token and atomic record of the decision to avoid issuing new tokens or sending multiple emails. The reset template should remain under the control of the authentication flow, with the support router classifying the contact but not becoming a secondary sender.
The design should have two layers: one for deduplication and another for idempotency key-based retries. A timeout should be treated as an unresolved state, with a reset-request record stored before calling the mail API. If the call times out, the same record and idempotency key should be reused for a retry. It is important to validate payloads against a schema and gate the creation of new tokens by user and recent token issuance.
Additionally, the DNS configuration must remain verified after any changes, and this state should dictate whether deployment or sending occurs. The TypeScript code provided demonstrates how to implement these principles, including a function to handle POST requests with idempotency keys and retry logic for handling timeouts.
