Making API Integrations ReliableWeb App Development
Summary: Integrations between systems fail silently more often than people realise. These practices keep data flowing reliably.

When your store, CRM, accounting system and logistics partners exchange data automatically, the business depends on those integrations working every time.

Expect failures

Networks drop, services go down and limits are reached. Design integrations to retry safely.

Use webhooks wisely

Webhooks deliver real-time updates but can arrive late or twice. Make processing idempotent so duplicates do no harm.

Log everything

Record each request and response so problems can be traced quickly.

Alert people

Notify the right person when an integration fails repeatedly.

Document the flows

Diagrams and runbooks help new team members understand and maintain integrations.

FAQs

How do we know if an integration has failed?

Monitoring and alerts should tell you before customers do.

What is idempotency?

Processing the same message twice without creating duplicates.

Should we build or buy integrations?

Use proven connectors where possible and custom code where needed.
