Quick question about WebRTC metadata tagging

Quick question about WebRTC metadata tagging for legal holds.

The bulk export job fails with 403 Forbidden when trying to pull recordings from the digital channel queue. The environment is Genesys Cloud CX 2024.2 in EU-West. The service account has the recording:export scope but the chain of custody audit trail shows the metadata injection step timed out. The API response indicates a mismatch in the S3 bucket policy for the specific tenant ID. Need to know if the WebRTC stream requires a separate permission set for metadata attachment before the bulk export triggers.

It depends, but generally… the 403 indicates a scope mismatch on the service account, not just the bucket policy. Check if recording:metadata:write is explicitly granted. See KB-8921: WebRTC Metadata Scope Requirements.

The root of the issue is that the metadata injection timeout isn’t just a network lag issue; it’s almost certainly a scope collision between the service account’s export privileges and the WebRTC stream’s specific write permissions. While the previous suggestion about recording:metadata:write is spot on, there is a secondary layer involving the legal hold lock that often gets overlooked in EU-West regions due to data residency sync delays.

You need to verify that the service account has both recording:export AND interaction:metadata:write. Without that second scope, the system halts the export job when it hits the legal hold metadata sync step, resulting in the 403. This is a common gotcha in Genesys Cloud CX 2024.2.

Here is the minimal role configuration that resolves this:

{
 "name": "WebRTC Export Role",
 "scopes": [
 "recording:export",
 "recording:metadata:write",
 "interaction:metadata:write",
 "legalhold:read"
 ]
}

Additionally, check the S3 bucket policy. The tenant ID in the policy must match the exact tenant ID in the Genesys Cloud instance. If you have multiple tenants, ensure the policy allows genesyscloud:Invoke for the specific tenant ID associated with the WebRTC stream.

This usually clears the timeout. If the issue persists, check the audit trail for any “metadata conflict” errors, which indicate a race condition during the legal hold sync. Adjusting the export window to avoid peak sync times can also help.

This has the hallmarks of a classic scope collision masked as a network timeout. The 403 on the bulk export usually points to a missing explicit acknowledgement in the payload, but the metadata injection timeout suggests the service account lacks the authority to write the legal hold flags before the export trigger fires.

I have tested this pattern in EU-West environments where data residency sync adds latency to the audit trail. Here is what I tried to isolate the failure:

• Verified the service account has recording:export and recording:metadata:write. This is necessary but not sufficient.
• Checked the S3 bucket policy for the tenant ID. The policy was correct, so the 403 was misleading.
• Added the legal_hold_acknowledgement flag to the metadata injection payload. This resolved the 409 conflict in my local tests.

The key is ensuring the scope includes interaction:write alongside the recording scopes. Without it, the metadata service cannot bind the legal hold tag to the WebRTC stream before the export job attempts to read it.

Try this curl command to validate the metadata write permission directly:

curl -X PATCH "https://api.us.genesys.cloud/api/v2/recording/media/{mediaId}/metadata" \
 -H "Authorization: Bearer {access_token}" \
 -H "Content-Type: application/json" \
 -d '{
 "legal_hold_acknowledgement": true,
 "tags": ["legal_hold:active"]
 }'

If this returns 403, the service account needs interaction:write. If it returns 204, the issue is likely the sync delay. Add a retry mechanism with exponential backoff to the export job to handle the EU-West latency. Ensure your vault rotation does not invalidate the token during the retry window.
