Messaging API 429 Rate Limiting on /v2/communications/messages

Encountering 429 Too Many Requests errors on the /v2/communications/messages endpoint. This occurs when our AppFoundry integration attempts to batch-send digital messages via the platform API.

The rate limit headers indicate we are exceeding the 100 requests/second threshold, despite implementing exponential backoff. The issue persists even with a single tenant connection.

Our OAuth2 token refresh logic is functioning correctly, ruling out authentication fatigue. The payload structure matches the documented schema exactly.

Are there specific headers or request patterns required to bypass this limit for premium app partners? We need to process high-volume chat routing updates without throttling.

It’s worth reviewing at the X-Rate-Limit-Remaining header to adjust your batch size before hitting the ceiling. The platform enforces strict throttling on digital communications to prevent abuse, so reducing concurrent requests is the only reliable fix.

Note: Ensure your export jobs do not trigger during peak message volume, as shared tenant limits apply.
