Python script hitting 429 on Genesys Cloud SMS receipt polling

Problem

We’re trying to pull SMS delivery receipts from Genesys Cloud using a Python script. The setup needs to query the Messaging API, parse carrier routing indicators, and map HTTP status codes to permanent blocks versus temporary network faults. Everything runs fine in staging until the production RETENTION WINDOW gets involved. Weird how the backoff logic starts choking. We’d rather stick to raw API integration than wrestle with the SDK again. We’ve also got latency tracking for the external gateway sync, but that’s falling behind.

Code

import requests
import time
import random

endpoint = "https://mydomain.genesyscloud.com/api/v2/messaging/sms/receipts"
headers = {"Authorization": f"Bearer {token}", "Content-Type": "application/json"}
payload = {"messageIds": [msg_id], "status": "DELIVERED", "carrierRouting": "TMOBILE"}

response = requests.post(endpoint, headers=headers, json=payload)
if response.status_code == 429:
 delay = 2 ** attempt + random.uniform(0, 1)
 time.sleep(delay)

Error

The endpoint keeps returning a 429 Too Many Requests after three cycles. The CIRCUIT BREAKER trips way too fast. We can’t get consistent receipts for the multi-carrier verification step. The POLLING INTERVAL is set to 5 seconds. The audit logs show massive polling latency.

Question

Does the receipt query payload need a specific timestamp range to bypass the RATE LIMITS? The jitter calculation looks right on paper. It’s just dropping heavy queries.

The 429 throttle usually kicks in when the polling interval matches the retention window flush cycle. Genesys Cloud treats rapid receipt queries a lot like a registration storm on a primary trunk. The platform drops requests faster than the failover pool can absorb them. You’ll want to inject exponential backoff with randomized jitter so the script doesn’t hammer the same endpoint during peak Eastern routing hours. Carriers like Twilio or Bandwidth also drop messages when the callback loops too tight.

Try swapping the linear retry logic for something like this:

import time
import random

def poll_receipts_with_backoff(base_delay=2, max_delay=30):
 delay = base_delay
 while True:
 try:
 response = fetch_sms_receipt()
 if response.status_code == 200:
 break
 except Exception as e:
 print(f"Retry needed: {e}")
 jitter = random.uniform(0, delay)
 time.sleep(delay + jitter)
 delay = min(delay * 2, max_delay)

Keep the delay ceiling under thirty seconds. The Ohio failover path drops packets the same way when the queue backs up. Usually clears up on its own. Just let the script breathe.

• The genesys-cloud-python SDK defaults to unauthenticated polling when you skip scope: messaging:conversation:read, which is exactly why you’re hitting the 429.
• Switch to a fixed polling interval instead of exponential backoff, since we tried the standard retry decorator, it failed on the retention flush boundary, and the Retry-After headers kept overriding our jitter, so doesn’t your client already disable connection pooling?
