Analytics API 429 Throttling on Multi-Tenant Partner App

Does anyone know the exact burst limits for the Conversation Details Query endpoint when operating under a Partner Org context? We are deploying a Premium App via AppFoundry that aggregates historical data across multiple customer orgs. The architecture uses a shared backend service that rotates through partner-specific OAuth tokens to fetch metrics.

During peak sync windows, specifically in the Pacific timezone morning hours, we are hitting consistent 429 Too Many Requests responses on POST /api/v2/analytics/conversations/details/query. The retry-after headers are erratic, sometimes suggesting 5 seconds, other times 60 seconds. We are not hitting the global org limits based on our internal counters, which suggests the throttling is applied at the integration or IP level rather than the tenant level.

“Rate limits for the Analytics API are enforced per organization and per API key. Partner applications should implement exponential backoff strategies to handle transient spikes.”

The documentation mentions per-org enforcement, but does not clarify if there is an additional ceiling for traffic originating from a single AppFoundry integration across multiple tenants. We are currently using the standard retry logic with jitter, but it is insufficient for the volume required. Is there a documented way to request a higher burst allowance for Partner Apps, or is this strictly capped?
