WEM Real-Time Adherence Data Stream Failing - 429 Too Many Requests

Genesys Cloud WFM

The WEM Real-Time Adherence data stream is dropping connections with a 429 Too Many Requests error - happening intermittently but enough to disrupt reporting. It’s impacting the REALTIME Adherence Source, so the data is stale. Seems like the API is throttling, but we haven’t hit any documented rate limits - or so I thought.

Here’s what we’ve checked:

  • Environment: Genesys Cloud US-East-1
  • SDK: Genesys Cloud Python SDK v1.28.0
  • API Endpoint: Historical adherence reporting endpoints (e.g., /api/v2/workforcemanagement/managementunits/{managementUnitId}/historicaladherencequery)
  • Poller Interval: Currently set to 30 seconds - tried bumping it to 60, didn’t resolve.
  • ACTIVE_ROLES configuration: The poller is using an integration user with the proper WEM read permissions.
  • CALL_CENTER_ID: Verified the poller is targeting the correct CALL_CENTER_ID.

The error is happening even when there’s minimal agent activity. Worth a shot checking if anyone else has seen this specific 429 with the adherence stream. The logs show this:

{
 "error": "Too Many Requests",
 "code": 429,
 "message": "Rate limit exceeded. Please try again later.",
 "details": {
 "type": "RateLimitExceeded",
 "retryAfter": 15
 }
}

That 429…it’s almost always the interval…you’re polling too frequently…right? We’ve found the WEM adherence stream isn’t designed for super-tight real-time needs…it’s more “near real-time.” Try bumping your SDK’s poll interval to 60s…it’ll kill the request rate…and the overhead from constant reconnects is significant…like, easily 20-30ms per connection attempt.

i think the API key maybe is wrong? we had same problem with the click-to-dial and the screen pop not work.
the Data Action is need correct permissions - you must to check the wemAdherence scope.

{
 "name": "WEM Adherence Data Action",
 "actionType": "http",
 "url": "/api/v2/workforcemanagement/agents/me/adherence/historical/jobs",
 "method": "POST",
 "headers": {
 "Authorization": "Bearer YOUR_API_KEY",
 "Content-Type": "application/json"
 },
 "scope": ["wemAdherence"]
}

just a hunch - the API token is maybe for wrong user.

are you pulling the adherence data directly from the stream, or are you using a Data Action to query it? we’ve seen this exact 429 thing a bunch - and it’s usually not the poll interval, surprisingly.

we had a similar issue a while back, and it turned out the SDK was aggressively retrying failed connections - hammering the endpoint. it’s almost like it wasn’t backing off enough between attempts. what we ended up doing was building a quick Lambda function to act as a proxy - the SDK hits the Lambda, the Lambda handles the retry logic with exponential backoff, then calls the adherence historical query endpoint.

here’s a super basic CloudFormation snippet for the Lambda - you’ll need to fill in the IAM role, obviously.

Resources:
 WemAdherenceProxy:
 Type: AWS::Lambda::Function
 Properties:
 FunctionName: WemAdherenceProxy
 Runtime: python3.9
 Handler: index.handler
 Role: !GetAtt LambdaRole.Arn
 Timeout: 30

it feels kinda hacky, but it worked around the throttling. the earlier post about the scope is good too - double-check that’s set right.

The retry behavior is almost certainly the issue - the exponential backoff in PlatformClientV2 isn’t aggressive enough for the WEM endpoint. We encountered a similar constraint when integrating real-time transcription - WER degraded by 3.2% when we didn’t implement a custom jittered retry mechanism (RFC 4648 spec applies to network packet reordering).

Consider this pseudo-code for a proxy Lambda:

function fetch_adherence_data():
 attempts = 0
 while attempts < max_attempts:
 try:
 data = call_genesys_cloud_api(**{"url": "/api/v2/workforcemanagement/managementunits/{managementUnitId}/adherence", "method": "GET"})
 return data
 except HTTP 429:
 attempts += 1
 wait_time = 2**attempts * base_delay + random.uniform(0, jitter)
 sleep(wait_time)
 return null # or error

Adjust base_delay and jitter (milliseconds) to tune the backoff.
