Performance

Tips

• Reuse HTTP connections (keep-alive). By default, axios/requests/HttpClient clients already do this.
• Enable compression (Accept-Encoding: gzip).
• Preload catalog data when issuing in batches (avoids a lookup per line).
• Process webhooks asynchronously — without blocking the response.

Expected throughput

• A single key: ~120 documents/min (rate limit).
• Multiple keys: linear parallelization up to Hacienda’s saturation point.
