Configure API integrations

Configure the API integration to fire event emails for abandoned carts. Map the cart-abandon event to the abandoned-cart template, ensure the payload includes cart total, items, and recovery link, and set the retry behavior to three attempts on 5xx responses. Deploy to staging, run three live test events with different cart states, and confirm the emails are received within two minutes.

Before I hand off this integration to engineering, make the API integration easy to approve: show the exact payload keys we require, call out which fields trigger personalization and which are mandatory, list failure modes and retries, and flag anything that would make the product manager hesitate to sign off — rate limits, security scopes, or data retention concerns.

I set up the abandoned-cart webhook to staging and the endpoint returns 200, but no emails appear in the inbox. I don’t know if the integration is mapping the right template ID, if throttling is blocking sends, or if the environment keys are wrong. What sequence of checks will quickly identify whether this is a mapping, authentication, or delivery issue and the best immediate fix to get test emails into inboxes?

Over several sprints we keep getting production incidents where API integrations fail because of wrong template IDs, environment keys, or undocumented payload changes, costing engineering hours and missed emails. I want an operational habit to prevent these regressions. What checklist, naming convention, or automated test should we adopt so integrations are resilient across deploys and handoffs?
