How to Protect an API Integration From Duplicate Webhook Events

Webhook providers may retry delivery when acknowledgments are delayed, so duplicate events are normal and should not repeat business actions. Checks to make Store the provider event identifier, acknowledge promptly after durable receipt, and process with an idempotent state transition. Track retries and processing failures, verify signatures, and test...

How to Diagnose an API Integration That Works Until Its Access Token Expires

An integration may fail after token expiry when refresh logic, scope, clock drift, or credential rotation is mishandled. Checks to make Capture status codes without secrets, confirm expiry and refresh behavior, check scopes and server time, test rotation safely, and alert before expiry. When to get help API engineering can improve authentication...

How to Plan an API Version Upgrade Before a Provider Removes the Old Version

An API version upgrade may change fields, error codes, authentication, pagination, or webhook behavior. Waiting until the old version is removed can turn a planned maintenance task into an outage. Inventory the integration surface Search code, configuration, logs, and scheduled jobs for the provider endpoints in use. Record request types, data fields,...

How to Detect When an API Pagination Change Truncates Imported Records

An integration can return HTTP success for every request and still import only part of a dataset if pagination behavior changes. Page size limits, cursor formats, sorting, or snapshot semantics may differ after an API update. Track the complete extraction Record each request cursor, response count, next-page indicator, and final source total where...

How to Process Out-of-Order Webhook Events Safely

Webhook delivery is often asynchronous, so an update event can arrive after a later event for the same record. Applying messages in arrival order may restore an older status or overwrite current data. Integrations need a way to recognize stale events and reconcile current state. Track event identity and version Store each provider event ID, resource...

How to Handle API Tokens That Expire During a Long-Running Job

An API job that runs for hours may succeed initially, then fail when its access token expires. Restarting the entire job can duplicate records or repeat expensive operations. The integration needs a secure refresh flow and a checkpoint that records what has already completed. Check the authentication lifecycle Review token lifetime, refresh-token...

How to Prevent Duplicate Records in an API Integration

When one system sends data to another, a timeout does not always mean the receiver failed to process the request. The sender may retry while the original operation is still completing, creating duplicate customers, invoices, or tickets. Integrations should be designed for repeated delivery rather than assuming every message arrives exactly once. Use a...

How to Version an Internal API Without Breaking Existing Clients

An API change can break consumers that depend on field names, ordering, error formats, or undocumented behavior. Checks to make Inventory clients and usage, define compatibility rules, add contract tests, introduce changes additively, and publish a deprecation period with migration examples. Monitor version usage and remove old behavior only after...
