Securely Managing Genesys Cloud OAuth Secrets in Terraform Using Remote State Encryption

What You Will Build

A Terraform configuration that provisions a Genesys Cloud OAuth Application without storing client secrets in the raw state file.
This tutorial uses the Genesys Cloud Provider for Terraform and AWS S3 with DynamoDB for remote state locking and encryption.
The implementation is written in HashiCorp Configuration Language (HCL).

Prerequisites

Genesys Cloud Account: An account with permissions to create OAuth Applications (admin or oauth_admin role).
Terraform: Version 1.5.0 or later.
Genesys Cloud Provider: Version 1.10.0 or later.
AWS Account: For hosting the encrypted remote state backend (S3 + DynamoDB).
AWS CLI: Configured with credentials that have s3:PutObject, s3:GetObject, dynamodb:PutItem, and dynamodb:GetItem permissions.
Environment Variables: You must have GENESYS_CLOUD_REGION, GENESYS_CLOUD_CLIENT_ID, and GENESYS_CLOUD_CLIENT_SECRET set in your shell for the initial Terraform authentication.

Authentication Setup

Terraform authenticates to Genesys Cloud using the genesyscloud provider block. For this tutorial, we assume you are using the standard OAuth Client Credentials flow.

Critical Note: The provider authenticates you (the developer running Terraform). The resources you create (the OAuth Apps) will have their own secrets. We are not storing your credentials in the state file; we are ensuring the created credentials are not stored in plain text.

# main.tf

terraform {
  required_version = ">= 1.5.0"

  required_providers {
    genesyscloud = {
      source  = "mikesplain/genesyscloud"
      version = "~> 1.10"
    }
    aws = {
      source  = "hashicorp/aws"
      version = "~> 5.0"
    }
  }

  # Define the remote backend for encrypted state storage
  backend "s3" {
    bucket         = "my-tf-state-secure-bucket"
    key            = "genesys-oauth-app/terraform.tfstate"
    region         = "us-east-1"
    dynamodb_table = "terraform-state-lock"
    encrypt        = true
  }
}

provider "genesyscloud" {
  # These values are read from environment variables.
  # Never hardcode these in the .tf files.
}

provider "aws" {
  region = "us-east-1"
}

Ensure your environment is configured before running any Terraform commands:

export GENESYS_CLOUD_REGION="mypurecloud.com"
export GENESYS_CLOUD_CLIENT_ID="your_admin_client_id"
export GENESYS_CLOUD_CLIENT_SECRET="your_admin_client_secret"

Run terraform init to initialize the backend. If your S3 bucket and DynamoDB table do not exist, create them first using the AWS CLI or an existing Terraform module.

Implementation

Step 1: Create the Genesys Cloud OAuth Application

The genesyscloud_oauth_client resource creates the application. By default, if you do not specify a client_secret, Genesys Cloud generates one. However, Terraform needs to track the resource. If the provider returns the secret in the API response, Terraform attempts to store it in the state file to detect drift.

To prevent this, we must use the sensitive argument. However, simply marking the output as sensitive is not enough if the provider inherently stores it in the state. The Genesys Cloud provider handles secrets carefully, but we must explicitly handle the data flow to ensure the secret is never written to the state file in a readable format, or ideally, not stored at all if we are relying on external secret management for retrieval.

In this tutorial, we will create the OAuth client and immediately export the secret to AWS Secrets Manager, then remove the dependency on the state file for the secret value in subsequent runs.

# resources.tf

# Create the OAuth Client
resource "genesyscloud_oauth_client" "my_secure_app" {
  name        = "Terraform-Managed-Secure-App"
  description = "OAuth app managed by Terraform with secret offloaded to AWS Secrets Manager"
  allowed_origins = [
    "https://example.com"
  ]
  redirect_uris = [
    "https://example.com/callback"
  ]
  client_type = "public" # or "confidential" depending on your use case
  # Note: We do NOT set client_secret here. Genesys generates it.
  # The provider will retrieve it on create.
}

Expected Response:
When you run terraform plan, Terraform will show a create action. Upon terraform apply, the Genesys Cloud API returns the client_id and client_secret.

Error Handling:
If you receive a 403 Forbidden error, verify that the environment variables GENESYS_CLOUD_CLIENT_ID and GENESYS_CLOUD_CLIENT_SECRET have the oauth:client:create scope.

Step 2: Offload the Secret to AWS Secrets Manager

We cannot simply “delete” the secret from the Terraform state if the resource still exists, because Terraform needs to know if the resource has changed. However, we can ensure the secret is not usable from the state file by storing it externally immediately after creation.

We will use the aws_secretsmanager_secret_version resource to store the generated secret.

# resources.tf

# Create the Secret in AWS Secrets Manager
resource "aws_secretsmanager_secret" "genesys_oauth_secret" {
  name                    = "genesys/oauth/${genesyscloud_oauth_client.my_secure_app.id}"
  description             = "Client secret for Genesys Cloud OAuth App ${genesyscloud_oauth_client.my_secure_app.name}"
  recovery_window_in_days = 0 # Immediate deletion when resource is destroyed

  tags = {
    Environment = "Production"
    ManagedBy   = "Terraform"
  }
}

# Store the secret value
resource "aws_secretsmanager_secret_version" "genesys_oauth_secret_value" {
  secret_id     = aws_secretsmanager_secret.genesys_oauth_secret.id
  secret_string = genesyscloud_oauth_client.my_secure_app.client_secret
}

Critical Security Note:
Even with encrypt = true in the S3 backend, the state file contains the decrypted JSON representation of the resource attributes during the Terraform process. By moving the secret to AWS Secrets Manager, we decouple the secret’s lifecycle from the Terraform state file’s readability. While the state file might still contain the secret value depending on provider implementation details, the authoritative source becomes AWS Secrets Manager.

To strictly prevent the secret from appearing in the state file, we rely on the sensitive flag in the provider schema. The Genesys Cloud provider marks client_secret as sensitive. This means it will not appear in the CLI output (terraform plan or apply), but it is still stored in the state file (encrypted by the S3 backend).

If your security policy forbids the secret from being in the state file at all, you must use the “Create Before Destroy” pattern with a null resource or rely on the fact that the S3 backend encryption (KMS) protects the data at rest. For this tutorial, we assume S3 encryption is sufficient for “at rest” protection, but we offload to Secrets Manager for “in use” retrieval by other systems.

Step 3: Retrieve the Secret Without Touching Terraform State

Other systems (CI/CD pipelines, other Terraform modules) should never read the Genesys OAuth secret from the Terraform state file. They should read it from AWS Secrets Manager.

We define an output that points to the secret, but we do not output the secret itself.

# outputs.tf

output "oauth_client_id" {
  value       = genesyscloud_oauth_client.my_secure_app.id
  description = "The Client ID for the Genesys Cloud OAuth Application."
}

output "oauth_secret_arn" {
  value       = aws_secretsmanager_secret.genesys_oauth_secret.arn
  description = "The ARN of the AWS Secret containing the Client Secret."
  sensitive   = true
}

# DO NOT output the client_secret directly
# output "oauth_client_secret" { ... }

Complete Working Example

Below is the complete main.tf file combining the backend configuration, provider setup, and resource definitions.

# main.tf

terraform {
  required_version = ">= 1.5.0"

  required_providers {
    genesyscloud = {
      source  = "mikesplain/genesyscloud"
      version = "~> 1.10"
    }
    aws = {
      source  = "hashicorp/aws"
      version = "~> 5.0"
    }
  }

  backend "s3" {
    bucket         = "my-tf-state-secure-bucket"
    key            = "genesys-oauth-app/terraform.tfstate"
    region         = "us-east-1"
    dynamodb_table = "terraform-state-lock"
    encrypt        = true
    # Optional: Specify a KMS key ID for custom encryption
    # kms_key_id = "alias/my-tf-state-key"
  }
}

provider "genesyscloud" {
  # Authentication via environment variables
}

provider "aws" {
  region = "us-east-1"
}

# 1. Create the Genesys Cloud OAuth Client
resource "genesyscloud_oauth_client" "my_secure_app" {
  name        = "Terraform-Managed-Secure-App"
  description = "OAuth app managed by Terraform. Secret stored in AWS Secrets Manager."
  
  # Define allowed origins and redirect URIs based on your application needs
  allowed_origins = [
    "https://your-frontend-app.com"
  ]
  
  redirect_uris = [
    "https://your-frontend-app.com/callback"
  ]
  
  client_type = "confidential"
  
  # Scopes required for the application
  scopes = [
    "conversation:call:view",
    "user:profile:read"
  ]
}

# 2. Create the AWS Secret Container
resource "aws_secretsmanager_secret" "genesys_oauth_secret" {
  name                    = "genesys/oauth/${genesyscloud_oauth_client.my_secure_app.id}"
  description             = "Client secret for Genesys Cloud OAuth App ID: ${genesyscloud_oauth_client.my_secure_app.id}"
  recovery_window_in_days = 0

  tags = {
    Environment = "Production"
    ManagedBy   = "Terraform"
    GenesysAppId = genesyscloud_oauth_client.my_secure_app.id
  }
}

# 3. Store the Generated Secret Value
resource "aws_secretsmanager_secret_version" "genesys_oauth_secret_value" {
  secret_id     = aws_secretsmanager_secret.genesys_oauth_secret.id
  secret_string = genesyscloud_oauth_client.my_secure_app.client_secret
}

# 4. Outputs
output "oauth_client_id" {
  value       = genesyscloud_oauth_client.my_secure_app.id
  description = "The Client ID for the Genesys Cloud OAuth Application."
}

output "oauth_secret_arn" {
  value       = aws_secretsmanager_secret.genesys_oauth_secret.arn
  description = "The ARN of the AWS Secret containing the Client Secret. Use this to retrieve the secret in your applications."
  sensitive   = true
}

How to Run:

Initialize the backend:
```
terraform init
```
Plan the changes:
```
terraform plan
```
Note: You will see [sensitive value] where the secret would appear.
Apply the changes:
```
terraform apply
```

Verify the secret in AWS Secrets Manager:

aws secretsmanager get-secret-value --secret-id genesys/oauth/<YOUR_CLIENT_ID> --query SecretString --output text

Common Errors & Debugging

Error: 403 Forbidden on OAuth Client Creation

Cause: The credentials provided in the environment variables (GENESYS_CLOUD_CLIENT_ID and GENESYS_CLOUD_CLIENT_SECRET) do not have the necessary permissions to create OAuth clients.

Fix: Ensure the admin client used for Terraform authentication has the oauth:client:create scope. You can verify this by checking the OAuth client settings in the Genesys Cloud Admin UI.

Code Check:

# Verify the scopes of your admin client
curl -X POST "https://api.mypurecloud.com/api/v2/oauth/token" \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "grant_type=client_credentials&client_id=$GENESYS_CLOUD_CLIENT_ID&client_secret=$GENESYS_CLOUD_CLIENT_SECRET"

Inspect the scope field in the response JSON. It must include oauth:client:create.

Error: S3 Bucket Not Found or DynamoDB Table Not Found

Cause: The backend configuration references an S3 bucket or DynamoDB table that does not exist.

Fix: Create the infrastructure before initializing Terraform.

# Create S3 Bucket
aws s3api create-bucket --bucket my-tf-state-secure-bucket --region us-east-1

# Create DynamoDB Table
aws dynamodb create-table \
    --table-name terraform-state-lock \
    --attribute-definitions AttributeName=LockID,AttributeType=S \
    --key-schema AttributeName=LockID,KeyType=HASH \
    --billing-mode PAY_PER_REQUEST \
    --region us-east-1

Error: State Lock Timeout

Cause: Another process is currently running Terraform against the same state file, or a previous run crashed and left a stale lock.

Fix: Check the DynamoDB table for existing lock items. If you are sure no other process is running, you can force unlock.

# Get the Lock ID from DynamoDB
aws dynamodb scan --table-name terraform-state-lock --query "Items[0].LockID.S"

# Force unlock (Replace <LOCK_ID> with the actual ID)
terraform force-unlock <LOCK_ID>

Error: Secret Not Found in AWS Secrets Manager

Cause: The genesyscloud_oauth_client resource was created, but the aws_secretsmanager_secret_version resource failed to apply.

Fix: Check the Terraform logs. Ensure the AWS provider has the secretsmanager:PutSecretValue permission.
