Data Manager API supports AWS KMS wrapped key information with a role ARN, KMS key URI, encrypted data encryption key, and key type. Permission, trust, format, or quota problems can surface only in downstream diagnostics.
Use this for privacy-conscious conversion or audience pipelines that encrypt formatted and hashed user data before upload.
Quick answer
Data Manager API AWS KMS Wrapped Key Permission Checklist should be handled with a narrow evidence-first workflow: validate identifiers, review trust and key policy, check wrapped dek, then verify the result before making broader changes.
What to check first
- Validate the IAM role ARN, AWS account, KMS key ARN, region, and supported key type.
- Review the role trust policy and KMS key policy for the documented Data Manager access path.
- Confirm the encrypted DEK is Base64 encoded and was wrapped by the referenced KMS key.
- Set the request encryption information and encoding to match the encrypted field representation.
- Retrieve diagnostics and classify AWS authentication, key permission, and decryption errors.
Diagnostic table
Use this table to keep the work practical. It connects the symptom to evidence and a verification step.
| Action | Evidence to collect | How to verify |
|---|
| Validate identifiers | Validate the IAM role ARN, AWS account, KMS key ARN, region, and supported key type. | The role and key ARNs point to the intended account, region, and resources. |
| Review trust and key policy | Review the role trust policy and KMS key policy for the documented Data Manager access path. | The KMS key can decrypt the wrapped DEK through the intended role. |
| Check wrapped DEK | Confirm the encrypted DEK is Base64 encoded and was wrapped by the referenced KMS key. | Diagnostics no longer report AWS authentication or decryption errors. |
| Match encoding | Set the request encryption information and encoding to match the encrypted field representation. | No raw user data, plaintext DEK, or long-lived AWS credential enters logs. |
Why this usually happens
- A valid role can still lack KMS decrypt permission on the specific key.
- The key ARN or region can point to a different key than the one that wrapped the DEK.
- Encoding can describe the payload incorrectly.
- KMS quota or trust failures can occur after the ingestion request is accepted.
Useful command or data shape
Adapt paths, IDs, and privacy handling to the site before running commands or storing data on production.
aws kms describe-key --key-id KEY_ARN --profile encryption-audit
aws iam get-role --role-name DATA_MANAGER_KMS_ROLE --profile encryption-audit
encryptionInfo:
awsWrappedKeyInfo:
roleArn: arn:aws:iam::123456789012:role/data-manager-kms
kekUri: aws-kms://arn:aws:kms:us-east-1:123456789012:key/KEY_ID
encryptedDek: BASE64_REDACTED
Safe fix order
Do the work in a sequence that makes each result easy to prove. Stop if a step produces new evidence that changes the incident scope.
- Validate identifiers
- Review trust and key policy
- Check wrapped DEK
- Match encoding
- Read diagnostics
What to tell the client or owner
Share redacted ARNs, policy owner, key version, encoding, request ID, diagnostic reason, and final successful status.
Production verification checklist
- The role and key ARNs point to the intended account, region, and resources.
- The KMS key can decrypt the wrapped DEK through the intended role.
- Diagnostics no longer report AWS authentication or decryption errors.
- No raw user data, plaintext DEK, or long-lived AWS credential enters logs.
Mistakes to avoid
- Do not judge the fix by one browser or the homepage only.
- Do not delete evidence before recording usernames, file paths, timestamps, and response headers.
- Do not add a cache, security, or tracking plugin while the original problem is still unclear.
- Do not leave test users, temporary debug logs, or broad API keys active after verification.
When HandL WP should help
Bring in help when this affects leads, checkout, search visibility, malware risk, paid media reporting, or a client production site. HandL WP can trace the issue through WordPress, hosting, cache, tracking, and Search Console, then verify the workflow after the technical fix.
If this is active on a production site, design a safer encrypted conversion upload.
