Has anyone figured out why the /api/v2/messaging/conversations endpoint is throwing 429 Too Many Requests even though we are strictly adhering to the documented rate limits for our AppFoundry integration? the issue started after the latest platform update in the US-EAST-1 region and only affects high-volume inbound channels while standard outbound flows seem unaffected. we have verified the oauth token refresh logic and confirmed no rogue background processes are hammering the api but the throttling persists regardless of request spacing.
You need to examine the queue activity and conversation detail views to identify if the volume spike is genuine or an artifact of flow logic. The 429 errors often correlate with rapid retry loops in Architect flows when a webhook fails, rather than simple API limit breaches. Check the Flow Error Handling settings in your messaging block. If the flow retries immediately upon a 429 status, it creates a thundering herd effect that exceeds the rate limit further.
A common fix is to implement exponential backoff logic within the flow itself. Use a Delay Block with a jittered wait time before any retry attempt. This smooths out the request rate and aligns with the platform’s throttling mechanisms. Additionally, verify the Queue Capacity settings. If the queue is saturated, the system may generate excessive status update calls, indirectly impacting the messaging endpoint load. Review the Performance Dashboard for queue depth spikes during the error windows. Adjusting the Agent Allocation Strategy to prioritize active conversations can reduce the overhead on the messaging API.
