What’s the cleanest way to push DNC compliance flags to a live contact list without breaking the callable time rules? Environment sits in US-East, Architect 2024Q3, Outbound API v2. The Python sync script handles 500 records per POST call. Payload looks standard. Just updating doNotCall to true and touching the customData array. Everything runs smooth for the first two batches. Then the response shifts to a 422 Unprocessable Entity.
Console output shows the error points to callableTimeRules validation. Says the rule set conflicts with the campaign’s default schedule. Got 14 separate callable windows configured for different state jurisdictions. The API can’t handle partial updates. Tries to overwrite the whole schedule block instead. Tried sending an empty array. Tried omitting the field entirely. Same 422 response. Screenshot of the validation error attached below. Took down the morning dialer for two hours while the suppression list backed up. Compliance needs these flags pushed before the 9 AM ET window. The docs mention partial merges but the actual endpoint behaves differently.
{
"message": "Validation failed for callableTimeRules. Overlapping schedule constraints detected for campaign default.",
"code": "VALIDATION_ERROR",
"details": ["Rule set cannot be null when doNotCall is updated without explicit schedule override."]
}
Retry loop is doing jack all. Logs just sit there after the third batch.
maybe you should isolate the DNC_FLAG update before touching the CUSTOM_DATA_ARRAY. the validation layer throws that 422 when CALLBACK_WINDOWS intersect with bulk field mutations. i usually prefer routing these changes through WEM anyway, but if you stick to the Outbound SDK, split the requests. send the compliance flag first. wait for the successful response. then apply the custom attributes in a separate call. the SCHEDULE_RULES checker gets confused when both objects change simultaneously. it’s running the callable time boundary logic twice and failing on the second pass. you’ll avoid the overlap error by staggering the payloads. don’t combine them in the same loop iteration.
PUT requests wipe the existing CALLABLE_TIME_RANGES array, which trips that validation layer. You’ll avoid the 422 error by switching to PATCH for the doNotCall toggle, and the ARCHITECT_FLOWS handle the routing logic much cleaner. Keeps the BATCH_SIZE limits sane.
The suggestion above about swapping to PATCH is fine, but the real culprit is how the outbound engine validates callableTimeRanges when customData gets touched in the same payload. If you’re pushing 500 records at once, the validation layer chokes on overlapping windows before it even checks the doNotCall flag.
Split the request. Push the DNC flag first using a dedicated /api/v2/outbound/contacts PATCH call. Keep the payload lean. Just {"doNotCall": true}. Wait for the 200 OK before firing off the custom data updates. The integration pipeline routes these through a ServiceNow REST endpoint anyway, so the webhook payload needs to look exactly like this:
{
"id": "{{contact_id}}",
"doNotCall": true
}
Don’t include callableTimeRanges at all. The docs explicitly state that omitting the array preserves the existing schedule. If you send an empty array, it wipes the schedule and triggers that 422. Check the outbound contact schema reference under field mutability rules. It saves a lot of headache down the line. The validation timeout still triggers if you exceed the rate limit though. Usually breaks around 450 calls per minute.
