Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this could be related to a recent deployment. Has there been any significant update or change to the API in the last 1-2 weeks?

Why it matters: Recent changes often correlate with performance issues. Expected answer: Yes, there was a minor update last week. Impact on approach: If confirmed, we'd focus on regression testing and code review.

• Considering the scale of the drop, I'm wondering about system-wide issues. Are we seeing similar drops in other API endpoints or just this specific marketplace integration?

Why it matters: Helps determine if it's an isolated or systemic problem. Expected answer: It's primarily affecting the marketplace integration API. Impact on approach: If isolated, we'd focus on that specific API's components.

• Given the nature of marketplace integrations, I'm curious about partner changes. Have any major partners updated their systems or integration methods recently?

Why it matters: Partner changes can significantly impact API performance. Expected answer: One major partner did update their integration last week. Impact on approach: We'd prioritize investigating that partner's integration specifically.

• Thinking about potential data issues, has there been any change in how we're measuring or defining "successful calls" in the past week?

Why it matters: Ensures we're not dealing with a measurement anomaly. Expected answer: No changes to measurement methods. Impact on approach: If confirmed, we can rule out data collection issues.
