Configuration guide
Follow these steps to initialize and authorize your FIS IBS Connector.1. Establish connectivity
Share connectivity details between Grand Central and FIS IBS as described in Network connectivity.VPN connectivity to the FIS IBS environment must be established before proceeding with configuration.
2. FIS IBS authentication
The FIS IBS Connector uses Basic Authentication for API access. To configure authentication, create a secret using Secrets Operations (SOPS). For more information, see How to create SOPS.To share credentials between FIS IBS and Grand Central, consider using 1Password.
3. Environment configuration
To initialize the FIS IBS Connector, define the required environment variables in yourgc-applications-live repository.
These variables are stored in values.yaml for configuration common to 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 invalues.yaml and are used across all FIS IBS connectors:
The following example shows the
values.yaml configuration:
Define deposit connector parameters
For the deposit connector, configure the following parameters: Deposit configuration (deposit-v0.values.yaml):
Define deposit-transactions connector parameters
For the deposit-transactions connector, configure the following parameters: Deposit transactions configuration (deposit-transactions-v0.values.yaml):
Define loan connector parameters
For the loan connector, use the following configuration: Loan configuration (loan-v0.values.yaml):
Define party connector parameters
For the party connector, configure the following parameters based on the version you’re using: Party v0 and v2 configuration (party-v0.values.yaml, party-v2.values.yaml):
These parameters apply to both party v0 and party v2 connectors.
Testing the connector
After configuration, test the connector using the API key authentication:
Test the API using the Postman collection.
Troubleshooting
If your connector isn’t responding as expected, check these common scenarios.5XX: Internal server error / Core system is down
5XX: Internal server error / Core system is down
Cause: The Grand Central gateway cannot establish a handshake with the FIS IBS endpoint. This typically indicates an upstream service outage at FIS or a network routing failure.Solution: Verify the operational status of the FIS IBS environment with FIS. If the service is operational, contact Grand Central Support.
5XX: Timeout from core / Read timeout / SocketTimeoutException
5XX: Timeout from core / Read timeout / SocketTimeoutException
Cause: The request to FIS IBS times out before receiving a response. This may indicate high latency or an unresponsive endpoint.Solution: Verify the operational status of the FIS IBS environment. If the service is operational, contact Grand Central Support.
Invalid OAuth token
Invalid OAuth token
Cause: The
client-id or client-secret provided during setup is incorrect.Solution: Verify your credentials with FIS and contact the Grand Central team to update the connection.429: Rate limit exceeded
429: Rate limit exceeded
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 FIS IBS 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.
