Digital Channel Bulk Export Job Failing with 403 on S3 Put Object

General Discussion
1

My current config is completely failing as expected when initiating a bulk export for a legal discovery request involving digital channel transcripts. The goal is to secure the chain of custody by moving raw JSON payloads directly to an S3 bucket via the Genesys Cloud Export API.

The export job starts successfully but fails at the transfer stage. The logs indicate a 403 Forbidden error from AWS S3 when Genesys attempts to write the files. The IAM role attached to the S3 bucket has s3:PutObject permissions, and the bucket policy allows access from the Genesys Cloud EU1 region.

Here is the relevant configuration snippet from the data action:

export_config:
 source: digital_transcripts
 filter:
 date_from: "2023-10-01T00:00:00Z"
 date_to: "2023-10-01T23:59:59Z"
 destination:
 type: s3
 bucket: "legal-hold-archive-eu1"
 region: "eu-west-1"
 prefix: "discovery/2023-10-01/"
 metadata:
 include_audit_trail: true

The include_audit_trail flag is critical for compliance. I have verified the bucket exists and the region matches. Is there a specific permission required for the Genesys service principal to assume the role, or is the issue related to the payload size of the digital channel metadata? Any insights on debugging the S3 integration for bulk exports would be appreciated.

This looks like a standard IAM policy mismatch or bucket policy restriction.

The export job starts successfully but fails at the transfer stage. The logs indicate a 403 Forbidden error from AWS S3 when Genesys attempts to write the files.

The 403 indicates the Genesys Cloud service principal lacks explicit permission to perform s3:PutObject on the target bucket. Even if the IAM role has broad permissions, bucket policies often override them. Ensure the bucket policy explicitly allows genesyscloud.com or the specific account ID as a principal.

Also check the KMS key policy if server-side encryption is enabled. The KMS key must allow kms:Decrypt and kms:GenerateDataKey for the Genesys principal. A common fix is adding a specific condition in the bucket policy:

{
 "Sid": "AllowGenesysPut",
 "Effect": "Allow",
 "Principal": { "AWS": "arn:aws:iam::123456789:role/GenesysExportRole" },
 "Action": "s3:PutObject",
 "Resource": "arn:aws:s3:::your-bucket/prefix/*"
}

Verify the region matches too. S3 endpoints are region-specific.
