Procore Header-Driven Rate Controller

Overview

Control throughput from the headers on each response instead of a hard-coded request count. Procore exposes whichever spike or hourly window is most likely to bind, and failed requests consume the same budget as successful calls.

Prerequisites

• Central request dispatcher with observable worker concurrency
• Durable queue and a clock synchronized well enough to interpret reset timestamps
• Metrics for status, route, remaining budget, reset time, retries, and backlog age

Instructions

Step 1: Capture every budget signal

Record X-Rate-Limit-Limit, X-Rate-Limit-Remaining, and X-Rate-Limit-Reset from each response. Preserve Retry-After for heavy-load responses.

Step 2: Pace before exhaustion
