Stuck on a bulk export job for a legal discovery request. The Data Action triggers the S3 upload but returns a 403 Forbidden error despite the IAM policy granting PutObject permissions.
The recording metadata includes the correct chain of custody fields, yet the platform rejects the payload before hitting the storage bucket. Any ideas on what permission scope is missing for digital channel recordings?
Make sure you check the resource path constraints in your IAM policy. the 403 forbidden error during s3 put object usually means the policy allows the action but restricts the specific bucket or prefix. in my load tests with high concurrent threads, i see this when the dynamic folder structure generated by genesys cloud doesn’t match the exact resource string in the aws policy. you need to allow arn:aws:s3:::your-bucket-name/* instead of just the bucket root. also, verify that the data action is using the correct aws region endpoint. if your genesys cloud instance is in us-east-1 but the policy points to a global endpoint, it will fail. here is a sample policy snippet that works for bulk exports:
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"s3:PutObject",
"s3:GetObject"
],
"Resource": "arn:aws:s3:::your-legal-hold-bucket/*"
}
]
}
the wildcard at the end is critical. without it, s3 rejects the put request because the recording files are nested in subdirectories based on date and agent id. also, ensure the iam role has a trust relationship with the genesys cloud data action service principal. sometimes the 403 masks a missing sts:AssumeRole permission if you are using role chaining. check the cloudwatch logs for the specific error code, not just the 403 status. it might say AccessDenied due to a missing x-amz-server-side-encryption header if your bucket has default encryption enabled. add the encryption header to your data action configuration if that is the case. this often happens in high-volume scenarios where the default timeout causes the encryption handshake to fail.
Generally speaking, the IAM configuration is only half the battle here. The previous suggestion regarding the arn:aws:s3:::your-bucket-name/* resource constraint is spot on, but there is a secondary layer of validation happening at the Genesys Cloud platform level before the request ever hits AWS.
When building Premium Apps that handle sensitive data like legal hold exports, the platform enforces strict bucket policy validation. Even if your IAM user has PutObject permissions, the S3 bucket policy itself must explicitly allow writes from the Genesys Cloud service principal. This is a common oversight in multi-org deployments where the bucket is shared across environments.
Ensure your bucket policy includes a statement allowing s3:PutObject for the specific principal arn:aws:iam::cloud.genesys.com:root (or the specific service ID provided in your org’s integration settings). Additionally, verify that the bucket does not have a default encryption setting that conflicts with the KMS key specified in the Data Action configuration. A mismatch here will silently trigger a 403 that looks like an IAM failure but is actually a server-side encryption rejection. Check the CloudTrail logs for a Deny event with a Condition element to confirm.
