When you encounter issues with your API usage, follow these steps:
1. Identify the Problem: Use your monitoring tools to pinpoint the exact issue. Is it a spike in API requests, slow response times, or a high error rate? 2. Investigate the Cause: Look into the root cause of the problem. It could be due to a recent change in your email marketing strategy, an issue with the API provider, or a problem with your integration. 3. Take Action: Once you have identified the cause, take appropriate action to resolve the issue. This could involve optimizing your API requests, contacting your API provider, or fixing bugs in your integration.
