Analytics API Throttling on Queue Summary Endpoint

General Discussion
1

The reporting dashboard freezes when the analytics API hits 45 requests per second. Ran a methodical test against /api/v2/analytics/queues/summary on v11.2.1 Tokyo org and throttling kicks in way before the documented 100 RPS ceiling. Token rotation doesn’t help. Sorry for the rookie question, but the payload cuts off mid-stream.

{"statusCode": 429, "error": "Too Many Requests", "details": "Rate limit exceeded. Burst closed. Threshold: 42/s. Retry: ..."}

Logs stop there.

Cause:
terraform-provider-cxascode wraps the underlying PureCloudPlatformClientV2 client, which handles rate limiting pretty aggressively when you hit burst thresholds. The platform actually splits that 100 RPS ceiling across tenant-wide analytics buckets, so when you start hammering /api/v2/analytics/queues/summary, the burst bucket drains way faster than the steady-state limit. You’re seeing that 429 because the SDK’s internal retry queue isn’t configured for exponential backoff by default. Token rotation won’t fix it since the limit is tied to the org ID and endpoint, not the bearer token. The payload cuts off because the HTTP stream gets terminated mid-response when the rate limiter flips the circuit breaker. Happens all the time when you ignore the burst window.

Solution:
You’ll need to inject a custom retry policy into the platform client config before the analytics service makes its calls. Here’s how you set it up in the Terraform provider block so the CX-as-Code layer respects the throttle window:

provider "genesyscloud" {
 client_config = {
 retry_max_attempts = 5
 retry_base_delay = "500ms"
 retry_max_delay = "5s"
 retry_backoff = "exponential"
 }
}

When terraform-provider-cxascode initializes, it passes those settings straight to PureCloudPlatformClientV2. The client then intercepts any 429 response, parses the Retry-After header, and backs off before firing the next batch. If you’re calling the API outside Terraform, you’ll want to mimic that exact flow in your script. Something like this curl wrapper handles the backoff manually:

#!/bin/bash
ENDPOINT="/api/v2/analytics/queues/summary"
TOKEN="your_oauth_token"
ATTEMPT=0
MAX_ATTEMPTS=5

while [ $ATTEMPT -lt $MAX_ATTEMPTS ]; do
 RESPONSE=$(curl -s -w "\n%{http_code}" \
 -H "Authorization: Bearer $TOKEN" \
 "https://api.mypurecloud.com$ENDPOINT")
 HTTP_CODE=$(echo "$RESPONSE" | tail -n1)
 BODY=$(echo "$RESPONSE" | head -n -1)
 
 if [ "$HTTP_CODE" == "429" ]; then
 ATTEMPT=$((ATTEMPT + 1))
 DELAY=$(( 2 ** $ATTEMPT ))
 echo "Rate limited. Retrying in ${DELAY}s..."
 sleep $DELAY
 else
 echo "$BODY"
 break
 fi
done

The key here is letting the retry logic handle the burst window instead of forcing synchronous requests. State drift usually shows up when the provider skips that backoff and half the queue configs get partially applied. Just drop that config block in your main.tf and let the client manage the queue. State drift stops showing up once the backoff kicks in.
