Bulk Export Job Failing with 403 on S3 Put

Could someone explain why our recording bulk export jobs are failing with a 403 error when pushing to our S3 bucket? The IAM policy allows PutObject but the Genesys Cloud service account seems to be missing permissions for the specific region endpoint. We are using the Recording API v2.1. More details at Genesys Docs.

Ah, yeah, this is a known issue when migrating permissions from Zendesk’s simpler bucket access to Genesys Cloud’s stricter S3 integration. The 403 error usually stems from the IAM policy lacking explicit s3:PutObjectAcl permissions, which Genesys Cloud requires even if PutObject is granted. Unlike Zendesk where file uploads were often handled via basic API tokens, Genesys Cloud service accounts need granular S3 rights. Check that your bucket policy explicitly allows the specific region endpoint and includes both PutObject and PutObjectAcl.

Ensure the S3 bucket policy also allows s3:GetBucketLocation to prevent silent failures during the initial handshake. Coming from Zendesk, where storage was abstracted away, this level of IAM configuration feels overwhelming at first. A quick fix is to add a conditional block in your IAM role allowing s3:* for the specific bucket prefix used by the export job. This mimics the broad access Zendesk macros had, but keeps it contained within the Genesys Cloud environment.

This seems like a standard IAM scope mismatch. The suggestion above correctly identifies s3:PutObjectAcl. When managing cross-region BYOC trunks, I also verify the bucket policy explicitly permits the Genesys service principal.

Check the bucket policy syntax carefully.
