Follow the steps in Get started before proceeding. Jack Henry Symitar access: An active account in the Jack Henry Symitar production or test environment. Network connectivity: Verify that your network routes traffic between the Jack Henry Symitar environment and Grand Central iPaaS. For supported options, see Network connectivity. Environment details: You need the following environment details from Jack Henry Symitar to configure the connector:

Configuration guide

Follow these steps to initialize and authorize your Jack Henry Symitar Connector.

1. Establish connectivity

Share connectivity details between Grand Central and Jack Henry Symitar as described in Network connectivity.
VPN connectivity to the Jack Henry Symitar environment must be established before proceeding with configuration.

2. Jack Henry Symitar authentication

The Jack Henry Symitar Connector uses SymXChange API authentication for API access. To configure authentication, create a Secrets Operations (SOPS) secret. For more information, see How to create SOPS.
To share credentials between Jack Henry Symitar and Grand Central, consider using 1Password.

3. Environment configuration

To initialize the Jack Henry Symitar Connector, define the required environment variables in your gc-applications-live repository. These variables are stored in values.yaml for common configuration across all connectors and in the following files for connector-specific configuration: For the full property list for each connector, including defaults and descriptions, see Reference.

Define common parameters

These variables are stored in values.yaml and are used across all Jack Henry Symitar connectors: The following example shows the values.yaml configuration:
Place the values files at the following paths:

Define party-v0 connector parameters

The party-v0.values.yaml file contains the basic configuration for the party v0 connector.

Define party-v2 connector parameters

The party-v2.values.yaml file contains advanced configuration including account type mappings, CXF client settings, thread pools, retry configuration, and error code mappings.

Define deposit connector parameters

The deposit-v0.values.yaml file contains configuration for deposit account operations including ShareCode mappings and product ID mappings. Account type mapping patterns:

Define deposit-transactions connector parameters

The deposit-transactions-v0.values.yaml file contains configuration for deposit transaction operations.

Define loan connector parameters

The loan-v0.values.yaml file contains configuration for loan account operations including LoanCode mappings and product arrangement mappings. Account type mapping patterns:

Define loan-transactions connector parameters

The loan-transactions-v0.values.yaml file contains configuration for loan transaction operations.

Define payment connector parameters

The payment-v0.values.yaml file contains configuration for payment operations.
Configure complete ShareCode and product ID mappings based on your institution’s account types. Contact your Jack Henry Symitar administrator for the full list.

Testing your integration

To access the Unified API, include your Grand Central subscription key in the request header. If you don’t have a key, contact the Grand Central Support Team to request one. Test the API using the Postman collection.
For more information about the Grand Central Unified API endpoints that support these features, see Jack Henry Symitar Connector Overview.

Troubleshooting

If your connector isn’t responding as expected, check these common scenarios.
Cause: The Grand Central gateway cannot establish a handshake with the Jack Henry Symitar endpoint. This typically indicates an upstream service outage at Jack Henry Symitar or a network routing failure.Solution: Verify the operational status of the Jack Henry Symitar environment. Check the Jack Henry status page or contact Jack Henry support. If the service is operational, contact Grand Central Support.
Cause: The request to Jack Henry Symitar exceeded the configured timeout period. This may indicate performance issues at Jack Henry Symitar or network latency problems.Solution: Verify the operational status of the Jack Henry Symitar environment and check for any performance degradation. If the service is operational and performing normally, contact Grand Central Support.
Cause: VPN connectivity to the Jack Henry Symitar environment has not been established or has been interrupted.Solution: Verify VPN connectivity and ensure routing is properly configured between Grand Central and Jack Henry Symitar.
Cause: The authentication credentials provided during setup are incorrect, expired, or the user lacks the required permissions in Jack Henry Symitar.Solution: Re-verify your credentials with your Jack Henry Symitar administrator and ensure the user has the required permissions. Contact the Grand Central team to update the connection credentials if needed.
Cause: The number of incoming requests exceeds the defined threshold for your subscription tier. This “429 Too Many Requests” response protects the stability of the Grand Central and Jack Henry Symitar infrastructure.Solution: Review your app’s request patterns to identify unexpected spikes. If you need higher throughput, contact the Grand Central team to request a higher rate limit.
