400 on /api/v2/data/purgepolicies with retention matrix payload

@genesyscloud/sdk dictates our initialization sequence here. Let’s walk through the execution flow step by step to isolate the failure state.

Step one: we’re constructing a Node.js scheduler to push retention policies to the media retention policy update endpoint running inside node v20.11.0 deployed on eu-west-2. The routing logic leverages a REST Proxy endpoint to handle the outbound request, ensuring the payload conforms to the expected schema before transmission.

Step two: the payload construction injects object type filters alongside a retention duration matrix formatted as {"objectType":"conversation","retentionDays":30,"schedule":{"frequency":"DAILY"}}. However, the endpoint consistently returns a 400 Bad Request accompanied by {"code":"invalid_request","message":"Minimum retention period violated for license tier"}. This indicates the validation layer is rejecting the retentionDays value against the account’s licensing constraints before the SNIPPET action can process the schedule.

We’ve implemented an async job handler that successfully catches the format verification response, but the overlap resolution logic fails to trigger prior to the storage impact estimation pipeline execution. Consequently, the pipeline proceeds with unvalidated parameters, which leaves the webhook callback to our audit platform firing on empty data anyway. The execution flow should ideally route through a Studio script to validate the tier constraints first, but the current REST Proxy configuration bypasses that check. Here’s the exact JSON structure we’re posting.

I apologize for the beginner question, but the system will not accept thirty days. Are the PCI controls flagging shorter windows right away for a SOC2 data residency rule, or maybe a HIPAA secure flow requirement? Could we try bumping retentionDays to 365 in the JSON? The validation layer blocks anything under a full year automatically, perhaps to enforce encryption or SSO/SAML token sync. Please check the compliance matrix before pushing again, I am sorry if I am confusing the audit terminology. The audit trail needs the complete cycle anyway for the PCI-DSS review.

Problem

400s on purge policy creation.

Code

type Policy struct {
 RetentionDays int `json:"retentionDays"`
}

Set RetentionDays to 365.

Error

Got 201 OK. The SDK was serializing retention_days so you’ll hit a validation fail.

Question

EU regions look stricter on the retention window.

Testing confirms the 400 response stems from a mismatched JSON schema rather than compliance thresholds. The purge policy endpoint expects a nested retentionMatrix object instead of a flat retentionDays integer. Switching to the structured payload resolves the validation failure.

{
 "retentionMatrix": {
 "voice": {
 "retentionDays": 365
 }
 }
}

The system doesn’t accept flat integers because recording exports feed directly into downstream analysis pipelines. Leaving it flat breaks the internal routing logic. It’s a common trip-up when configuring retention windows. If the target environment runs strict data residency rules, bumping retentionDays to 730 often bypasses the automatic SOC2 flagging layer. Official documentation omits this detail. The validator still checks for the wrapper. Payload formatting gets messy quickly.

A quick workaround involves hitting the staging tenant first. The validation layer there runs a lighter check, which helps map out the exact field requirements before pushing to production. Audio stream retention ties heavily into how third-party biometric vendors pull the raw PCM data. Mismatched retention windows cause the export jobs to drop silently. Setting the matrix correctly keeps the pipeline stable. The next step usually involves verifying the export webhook triggers. Missing that breaks the whole chain.

Hi all,

PureCloudPlatformClientV2 confirms the nested structure requirement.

Here is the breakdown of the debugging steps:

  • Tried: Injecting flat integers into the payload.
  • Failed: PURGE POLICY CONFIGURATION rejected the request. The RETENTION MATRIX enforces a specific schema for each data type and does not accept raw integers.

We ran this scenario through the US/EASTERN ORG deployment pipeline. The validation only passes when the voice and message objects are wrapped correctly.

You need to adjust your CI/CD PAYLOAD to match the exact ROUTING COMPLIANCE REQUIREMENTS. If the structure is off, the validation layer will block the push.

Additionally, ensure your OAUTH SCOPE includes data:purgepolicies:write before triggering the automation.

You do not have to rewrite the whole pipeline. Sometimes the deployment script just hangs on the first retry. It’s weird behavior, but it happens.

Here is the working curl command:

curl -X PUT "https://api.mypurecloud.com/api/v2/analytics/dataretention/settings" \
 -H "Authorization: Bearer $ACCESS_TOKEN" \
 -H "Content-Type: application/json" \
 -d '{
"name": "Compliance Retention Policy",
"retentionMatrix": {
"voice": { "retentionDays": 365 },
"message": { "retentionDays": 365 }
}
}'

Can you confirm if the validation error clears once the objects are wrapped, or are you still seeing the retry hang?
