Hitting 503 Service Unavailable on POST /api/v2/analytics/details when querying screen recording metadata under 50 concurrent threads. The standard voice recording endpoints hold up fine, but the screen recording metadata requests fail consistently. Using JMeter 5.4.1 against the US1 org. Is there a specific rate limit for screen recording analytics queries that isn’t documented?
This 503 behavior usually indicates that the analytics aggregation service is overwhelmed by concurrent read requests, rather than a hard-coded rate limit on the endpoint itself. The /api/v2/analytics/details endpoint performs heavy joins on screen recording metadata, which is significantly more resource-intensive than standard voice recording lookups.
When integrating this with ServiceNow for ticket creation, avoid real-time polling during high-concurrency events. Instead, implement a Data Action that triggers on the screen_recording_complete event. This pushes the metadata directly into ServiceNow via a single REST call, bypassing the need to query the analytics API under load.
If you must query the API, implement exponential backoff in your JMeter script. Start with a 1-second delay and double it on each 503 response. Also, ensure your query filters are as narrow as possible. Broad date ranges combined with high concurrency will almost certainly trigger the 503.
