Bot Transcript Export 403 Forbidden with S3 Integration for Legal Hold

Architect & Flows

{ "error_code": "403", "message": "Access Denied", "details": "Pre-signed URL generation failed for bucket: legal-archive-eu-west-1" }

Encountering a persistent block when attempting to export digital channel transcripts via the Genesys Cloud Recording API. The workflow involves triggering a bulk export job for chat transcripts tagged with a specific legal hold identifier. The environment is EU-West-1, utilizing Genesys Cloud v2 APIs. The integration point is an S3 bucket configured with a specific IAM role that has been granted s3:PutObject permissions via a trust policy.

The issue manifests specifically when the export job attempts to generate the pre-signed URL for the destination bucket. The job status transitions to FAILED immediately after the URL generation step. The error log indicates a 403 Forbidden response from AWS, despite the IAM role being correctly attached to the Genesys Cloud integration profile. The bucket policy explicitly allows Principal: * with a condition on the aws:SourceVpc matching our VPC endpoint, which is standard for our chain of custody requirements.

The query parameters for the recording export request include the include_metadata flag set to true, ensuring all session details are captured for audit trails. The timestamp of the failure correlates exactly with the API call to /api/v2/recordings/jobs/{id}/export. Previous exports for voice recordings succeed without issue, suggesting the problem is isolated to digital channel transcript handling or the specific metadata payload size.

Has anyone encountered similar restrictions when exporting chat transcripts with extensive metadata? The S3 bucket region matches the Genesys Cloud environment, ruling out cross-region latency issues. The IAM role ARN is verified and active. The request payload includes the correct content_type of application/json. Looking for insights on whether there is a hidden quota or a specific permission scope required for digital channel transcript exports that differs from voice recordings.

  • Check if the IAM role attached to the export job has s3:GetObject permissions for legal-archive-eu-west-1.
  • Verify the pre-signed URL policy isn’t expiring before the export completes.
  • Ensure the bucket policy allows access from the Genesys Cloud EU-West-1 service principal.
  • 403s usually mean permission mismatch, not rate limits.

it depends, but generally… the issue isn’t just the IAM role permissions as mentioned above, but rather how the pre-signed URL is being generated and consumed within the integration flow. from a vendor perspective, we see this 403 frequently when the client application doesn’t respect the HTTP method constraint in the policy document. the default policy often allows only GET requests, but if your export workflow attempts to initiate a multipart upload or uses a different verb, S3 rejects it immediately.

also, check the bucket policy for IP-based restrictions. genesys cloud’s EU-West-1 endpoints egress from specific CIDR ranges. if your bucket policy has a Condition block limiting source IPs, it will block the request even if the IAM role is correct. you need to allow the genesys cloud service principal or the specific VPC endpoint if you’re using a private link setup.

here is a sample policy snippet that usually resolves this. ensure the Principal is set correctly and the Action matches your export method:

{
 "Version": "2012-10-17",
 "Statement": [
 {
 "Sid": "AllowGenesysExport",
 "Effect": "Allow",
 "Principal": {
 "AWS": "arn:aws:iam::123456789012:role/genesys-export-role"
 },
 "Action": [
 "s3:GetObject",
 "s3:PutObject"
 ],
 "Resource": "arn:aws:s3:::legal-archive-eu-west-1/*"
 }
 ]
}

if you are using a custom integration via appfoundry, make sure the oauth token used to generate the pre-signed url has the recordings:export:read scope. missing scopes can also manifest as 403s if the api call fails before reaching s3. verify the token claims in the developer portal.

The way I solve this is by defining the s3 policy in terraform. check the principal matches the eu-west-1 service account.
