The linked pages require a login. Access is limited to Backbase staff, partners, and customers. If you don't have access, contact your Backbase account team. Use this page when you integrate Backbase Digital Banking with Grand Central. It links to the Backbase IO documentation for each integration point. The following diagram shows the two mechanisms that Digital Banking and Grand Central use to exchange data: ```mermaid theme={"system"} %%{init: { 'theme': 'base', 'themeVariables': { 'primaryColor': '#ffffff', 'primaryBorderColor': '#295eff', 'primaryTextColor': '#091c35', 'lineColor': '#091c35', 'secondaryColor': '#f3f6f9', 'tertiaryColor': '#ebf0f5', 'fontFamily': 'Libre Franklin, sans-serif' } }}%% graph LR DB[Backbase Digital Banking] GC[Grand Central] DB -->|REST API| GC GC -->|Sync Hub events| DB ``` **Digital Banking** encompasses Foundation Services, Identity, Banking Services, Digital Investing, Digital Onboarding, Digital Lending, Flow Foundation, and Engage Services. ## Integration methods Digital Banking integrates with Grand Central in two ways: * **REST API:** Digital Banking services call Grand Central unified APIs directly or through an adapter. * **Sync Hub (event-based):** Grand Central publishes events on Sync Hub and Digital Banking services ingest them to keep local data in sync. Not every Backbase backend service integrates with Grand Central. Some services are standalone and don't rely on a third-party system. ## REST API integration scenarios Digital Banking services that use REST APIs to integrate with third-party systems define three types of integration APIs: * **Outbound**: The Digital Banking service calls this API to push changes to the external system. * **Pull**: The Digital Banking service calls this API to fetch updates from an external system. * **Inbound (out of scope)**: The Digital Banking service exposes this API. The external system pushes changes to the Digital Banking service (often through an integration service). Inbound integrations are out of scope for Grand Central. Grand Central only uses events through Sync Hub to push changes to the Digital Banking services. Grand Central doesn't support the outbound and pull integration APIs. It only supports its unified APIs. To integrate with Grand Central, Digital Banking services either call the unified APIs instead of their outbound or pull APIs, or they use an adapter service to mediate between those APIs. ### Scenario 1: Integration through an adapter The Digital Banking service calls an adapter that implements its outbound integration API and consumes the corresponding unified API in Grand Central. A Grand Central-managed connector serves the unified API. The following diagram shows this flow: ```mermaid theme={"system"} %%{init: { 'theme': 'base', 'themeVariables': { 'primaryColor': '#ffffff', 'primaryBorderColor': '#295eff', 'primaryTextColor': '#091c35', 'lineColor': '#091c35', 'secondaryColor': '#f3f6f9', 'tertiaryColor': '#ebf0f5', 'fontFamily': 'Libre Franklin, sans-serif' } }}%% graph LR DB[Digital Banking service] -->|Outbound or pull integration API| A[Adapter] A -->|Unified API| GC[Grand Central-managed connector] ``` The following table lists the Digital Banking services that have an adapter: | Domain | Capability | Service | Adapter | Backbase IO reference | | ---------------- | --------------------------------------- | ----------------------- | -------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | Identity | Self-Enrollment | `enrollment-manager` | `enrollment-support-integration` | [Configure the Enrollment Support integration service](https://backbase.io/documentation/identity/2026.07/self-enrollment/services/integration/enrollment-support-integration-configure) | | Identity | User Management: User Manager service | `user-manager` | `user-profile-integration` | [Configure the User Profile integration service](https://backbase.io/documentation/identity/2026.07/user-management/integration/user-profile-integration-configure) | | Banking Services | Access Control | `access-control` | `legalentity-integration` | [Develop the legal entity outbound integration service](https://backbase.io/documentation/banking-services/2026.07/access-control/services/access-control-develop-integration-service-legal-entity-outbound) | | Banking Services | Accounts and Transactions: Accounts | `arrangement-manager` | `arrangement-integration` | [Accounts reference](https://backbase.io/documentation/banking-services/2026.07/accounts-transactions/services-products/product-summary-reference) | | Banking Services | Accounts and Transactions: Transactions | `transaction-manager` | `transaction-integration` | [Transactions reference](https://backbase.io/documentation/banking-services/2026.07/accounts-transactions/services-transactions/transactions-reference) | | Banking Services | Loans | `loan` | `loan-integration` | [Loans setup (integration mode)](https://backbase.io/documentation/banking-services/2026.07/loans/services/loans-setup#_integration_mode) | | Banking Services | Payments | `payment-order-service` | `payment-integration` | [Payments reference](https://backbase.io/documentation/banking-services/2026.07/payments/services/payments-reference) | ### Scenario 2: Direct integration The Digital Banking service directly calls the unified API in Grand Central. A Grand Central-managed connector serves the unified API. The following diagram shows this flow: ```mermaid theme={"system"} %%{init: { 'theme': 'base', 'themeVariables': { 'primaryColor': '#ffffff', 'primaryBorderColor': '#295eff', 'primaryTextColor': '#091c35', 'lineColor': '#091c35', 'secondaryColor': '#f3f6f9', 'tertiaryColor': '#ebf0f5', 'fontFamily': 'Libre Franklin, sans-serif' } }}%% graph LR DB[Digital Banking service] -->|Unified API| GC[Grand Central-managed connector] ``` The following table lists the Digital Banking services that directly call unified APIs: | Domain | Capability | Service | Backbase IO reference | | -------------------------------------------------------- | ------------------------------------------ | ---------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Foundation Services | Customer Profile | `customer-profile` | [Integrate with the core banking system through the unified API](https://backbase.io/documentation/foundation-services/2026.07/customer-profile/integrate-with-core-banking-system#cps-unified-party-integration) | | Banking Services | Certificates of Deposit | `term-deposit-manager` (part of Local Bundles) | [Configure Grand Central integration](https://backbase.io/documentation/banking-services/2026.07/certificates-of-deposit/services/configure-grand-central-integration) | | Banking Services | Contacts | `contact-manager` | [Verify payee information using verification of payee](https://backbase.io/documentation/banking-services/2026.07/contacts/services/contacts-how-to-verification-of-payee) | | Banking Services | Family Banking: Deposit Account Management | `deposit-account-management` | [Understand integration types](https://backbase.io/documentation/banking-services/2026.07/family-banking/services-deposit-account-management/understand#_integration_types) | | Digital Onboarding, Digital Lending, and Flow Foundation | Integrated Account Opening | `party-profile-service` | [Integration with the core banking system](https://backbase.io/documentation/flow-foundation/2026.07/integrated-account-opening/party-profile-service/party-profile-reference#party_profile_core_integration) | ### Scenario 3: Custom adapter The following table lists the Digital Banking services that need a custom adapter. The adapter implements their outbound or pull API and calls the Grand Central unified API. Some of these services also ship with a connector that integrates directly with an external system and doesn't use Grand Central. | Domain | Capability | Service | Grand Central integration | Direct integration connectors (no Grand Central) | | ----------------- | --------------------------------------------- | ------------------------------ | -------------------------------------------------------------------------- | ---------------------------------------------------------------- | | Identity | User Management: User Profile Manager service | `user-profile-manager` | Custom | Custom | | Banking Services | Account Statements | `account-statement` | Custom | Custom | | Banking Services | Accounts and Transactions: Transactions | `transaction-manager` | Custom (enrichment) | `transaction-enricher` (enrichment with MX, SaltEdge, or Yodlee) | | Banking Services | Appointments | `appointment` | Custom | `appointment-jrni-integrator` (JRNI) | | Banking Services | Batches | `payment-batch` | Custom | Custom | | Banking Services | Calendar | `bank-calendar` | Custom | Custom | | Banking Services | Card Management | `card-manager` | Custom | `entrust-card-connector` (Entrust) | | Banking Services | Contacts | `contact-manager` | Custom (contact store), directly calls unified API (verification of payee) | Custom (contact store) | | Banking Services | Financial Insights | `financial-picture` | Custom | Custom | | Banking Services | Payments: Vendor | `customer-provider-integrator` | Custom | `payveris` (Paymentus) | | Banking Services | Product Shopping: Product Matching | `product-matching` | Custom | Custom | | Digital Investing | Investment | `investment` | Custom | Custom | ## Sync Hub integration The following table lists the Digital Banking services that ingest events from Sync Hub to receive data from Grand Central.

The following table lists the Digital Banking services that have integrations that are not covered by Grand Central unified APIs. Some ship with a connector that directly integrates with an external system without Grand Central. | Domain | Capability | Service | Direct integration connectors (no Grand Central) | |
