Jack Henry SilverLake Integration Guide

Integrate SilverLake with enterprise applications through institution-provisioned jXchange SOAP/XML services, secure workflows, and controlled API façades.

Jack Henry SilverLake integration options at a glance

SilverLake is typically integrated through institution-provisioned Jack Henry interfaces rather than a broadly public developer API. jXchange SOAP/XML services are the primary mechanism to investigate, with available operations, WSDLs, credentials, certificates, and permissions dependent on the financial institution’s contract and environment. A general-purpose SilverLake REST API, webhook platform, bulk API, and direct production database access were not confirmed. File exchange or scheduled processing may exist for selected implementations but requires validation. Martini can consume approved SOAP services, transform XML into JSON or downstream formats, expose controlled REST APIs, schedule polling workflows, apply business rules, and protect endpoint configuration and credentials through secure environment settings.

Integration pointSupported by Jack Henry SilverLake?Common use casesHow Martini supports it
SOAP APIsLimitedjXchange is associated with SOAP/XML integration to Jack Henry core systems, including SilverLake environments. Available services and operations depend on the institution’s contract, WSDLs, and enabled permissions.Martini can consume SOAP APIs from workflows, send approved requests, transform XML responses, handle SOAP faults, and isolate vendor schemas from downstream models.
REST APIsNot confirmedJack Henry provides API products across its portfolio, but a public SilverLake-specific REST API was not verified.If the institution provides REST access through an applicable Jack Henry product or intermediary, Martini can consume it; otherwise jXchange SOAP is the principal route to investigate.
Webhooks / outbound callbacksNot confirmedA general-purpose SilverLake webhook mechanism for customer, account, loan, or transaction changes was not confirmed.Martini can receive a callback if Jack Henry or institution-managed middleware provides one, but event coverage and delivery behavior must be confirmed.
Bulk / async / batch APIsNot confirmedInstitution-specific batch processing may exist, but a standard public SilverLake bulk or asynchronous API was not verified.Martini can orchestrate scheduled or batch-style workflows when an approved service or file process is supplied, including checkpoints and reconciliation.
File exchangeNot confirmedFile-based exchange may be used for selected banking workflows, but a standard SilverLake file API was not verified.Martini can process an institution-approved file flow when format, delivery, encryption, signing, acknowledgements, and replay rules are defined.
Database accessNot confirmedDirect production database access should not be assumed and is not the preferred SilverLake integration approach.Martini can connect to authorized databases in general, but SilverLake integrations should use Jack Henry-supported service interfaces unless direct access is explicitly approved.
AuthenticationLimitedSecure service integration may use institution-specific credentials, TLS, SOAP security values, client certificates, endpoint configuration, and service permissions. OAuth 2.0 should not be assumed for jXchange.Martini can store secrets and endpoint settings securely, configure transport and service authentication, and keep credentials outside workflow logic.
Scheduled synchronizationLimitedPolling may be required when event notifications are unavailable, subject to supported query operations, filters, response limits, and incremental retrieval features.Martini can schedule workflows, persist watermarks, apply bounded concurrency, transform results, and retry or reconcile failed runs.

How Jack Henry SilverLake exposes data and business events

Jack Henry jXchange SOAP APIs

jXchange is the most relevant SilverLake integration mechanism identified in the research. It is associated with SOAP/XML services for Jack Henry core integrations, but service definitions, operations, security, and access depend on the institution’s licensed products and environment.

Martini implementation pattern

Martini implementation pattern: Martini workflows consume the institution-provided WSDL-backed service, create approved SOAP requests, send them over secured HTTPS, parse XML responses or faults, and map vendor-specific structures to canonical or downstream models. SOAP headers, certificates, credentials, namespaces, and endpoint settings remain environment-specific.

Implementation sequence

Obtain the institution’s jXchange WSDLs, endpoints, credentials, certificates, and enabled
Configure secured SOAP access in Martini
Receive an API request or scheduled workflow trigger
Build and send the approved SOAP request
Parse the SOAP response or fault
Map XML fields to the target model and apply business rules for sensitive data and state

Scheduled SilverLake synchronization

Because a general-purpose SilverLake webhook mechanism was not confirmed, scheduled polling may be required for account, customer, loan, or transaction activity. The available service must be checked for date filters, modified timestamps, sequence numbers, or continuation tokens.

Martini implementation pattern

Martini implementation pattern: a scheduler starts a workflow that retrieves bounded data windows from supported operations, transforms the response, writes it to downstream systems, and stores a reliable watermark. Retries and replay must account for duplicate or uncertain processing.

Implementation sequence

Define the supported query, time window, and watermark field
Start the Martini workflow on an approved schedule
Retrieve a bounded SilverLake data set
Map and validate each Customer, Account, Loan, or Transaction item
Write accepted items to the downstream system
Persist the checkpoint and route failures for retry or reconciliation

Institution-provided callbacks or files

No general SilverLake callback platform or standard file API was verified. A specific Jack Henry product, institution-managed middleware flow, or approved file exchange may nevertheless be available under an implementation agreement.

Martini implementation pattern

Martini implementation pattern: when an institution provides a callback or file process, Martini receives or retrieves the agreed payload, validates authenticity and format, transforms it, and records acknowledgements and replay identifiers. Delivery, encryption, signing, duplicate handling, and schedules must be defined before implementation.

Implementation sequence

Confirm the institution-provided callback or file contract
Configure the approved endpoint or delivery location
Receive the notification or file and validate its identity
Parse the payload and reject invalid or duplicate deliveries
Map data to the downstream model and apply business rules
Record acknowledgement, processing status, and replay information

Common Jack Henry SilverLake integration patterns

Pattern 1: Expose a controlled SilverLake lookup API

When to use this pattern

Use this pattern when applications need customer, deposit account, or loan information but should not connect directly to jXchange. Availability depends on the institution’s enabled read operations and permissions.

Integration direction
External application
Martini
Jack Henry SilverLake
Example Mapping
Jack Henry SilverLake FieldCanonical FieldTarget Field
CustomerNumbercustomerIdrequest.customerId
AccountNumberaccountIdresponse.accountId
CurrentBalancecurrentBalanceresponse.balance
Martini implementation pattern

A Martini REST API validates the lookup key, calls the applicable SilverLake SOAP operation, maps the XML response into a controlled JSON contract, filters sensitive fields, and returns a consistent error model. Timeouts, SOAP faults, and unknown outcomes are logged with correlation identifiers rather than exposing raw payloads.

Martini capabilities used
  • APIs
  • workflows
  • SOAP API consumption
  • data mapping
  • business rules
  • error handling

Pattern 2: Synchronize SilverLake transactions to digital channels

When to use this pattern

Use this pattern when Q2, Alkami, Salesforce, or another approved downstream system requires account activity and no suitable SilverLake event mechanism is available. Incremental query support must be confirmed.

Martini implementation pattern

A scheduled workflow retrieves a bounded transaction window through an approved service operation, applies date or watermark criteria, maps XML into a canonical activity model, and writes downstream changes idempotently. The workflow persists its checkpoint, uses bounded concurrency, and routes duplicates or uncertain writes to reconciliation.

Martini capabilities used
  • scheduled workflows
  • SOAP API consumption
  • data mapping
  • transformation
  • idempotency rules
  • retry and reconciliation

Pattern 3: Process loan servicing requests

When to use this pattern

Use this pattern when MeridianLink, nCino, or another lending application must submit approved customer or loan information to SilverLake. Write operations and permissions must be confirmed before implementation.

Integration direction

Martini implementation pattern

Martini receives and validates the lending request, enriches it with approved customer data when necessary, constructs the institution-specific SOAP request, and records the response. State-changing operations use request identifiers, conservative retry rules, and a reconciliation path for timeouts or indeterminate outcomes.

Martini capabilities used
  • API exposure
  • workflow orchestration
  • validation
  • data mapping
  • business rules
  • error handling

Pattern 4: Reconcile SilverLake accounts and ledger activity

When to use this pattern

Use this pattern for periodic comparison of SilverLake Customer, Deposit Account, Loan Account, Transaction, or General Ledger Account data with a downstream finance or reporting process.

Martini implementation pattern

A scheduled Martini workflow retrieves approved data sets, normalizes identifiers and numeric formats, compares source and target values, and emits discrepancy results. It stores checkpoints, avoids direct database assumptions, and routes material mismatches or incomplete responses to controlled review queues.

Martini capabilities used
  • scheduled workflows
  • SOAP API consumption
  • mapping and transformation
  • comparison rules
  • exception routing
  • monitoring

Applications commonly integrated with Jack Henry SilverLake

Financial institutions can use Martini to mediate between SilverLake and adjacent banking, lending, customer-engagement, and digital-channel products. These relationships are architectural patterns rather than confirmation of turnkey SilverLake interfaces; supported operations and permissions must be validated for each institution.

Application Scenario Direction Martini Pattern
Salesforce Synchronize customer profiles, account relationships, service context, and selected financial activity for relationship management. Jack Henry SilverLake → Martini → Salesforce A scheduled or API-led workflow retrieves approved Customer/CIF, Deposit Account, and Transaction data through jXchange, maps it to Salesforce objects, applies field-level filtering, and records failures for retry or review.
Microsoft Dynamics 365 Provide customer and account information to customer-engagement, sales, and service workflows. Jack Henry SilverLake → Martini → Microsoft Dynamics 365 Martini exposes a controlled API or runs scheduled synchronization, calls the available SilverLake services, transforms SOAP/XML into the Dynamics 365 model, and restricts reverse updates to institution-approved operations.

Authentication and security considerations

Institution-specific access

SilverLake access depends on the financial institution’s Jack Henry deployment, licensed services, enabled operations, and security approvals. Obtain the applicable WSDLs, endpoints, credentials, certificates, and permissions before implementation.

Transport and service security

  • Use TLS-secured HTTPS and validate certificates.
  • Configure institution-approved service credentials and SOAP security values.
  • Use client certificates or other certificate-based trust controls where required.
  • Do not assume OAuth 2.0 for jXchange.
  • Store secrets and endpoint configuration in secured Martini environment settings.

Sensitive data controls

  • Apply least-privilege service permissions.
  • Mask account numbers and customer data in logs.
  • Avoid retaining complete SOAP payloads unless required and protected.
  • Separate test and production credentials and endpoints.

Operational considerations for Jack Henry SilverLake integrations

Contracts and schemas

Track WSDL and XML schema versions, namespaces, required headers, enumerations, optional elements, date formats, decimal formats, and institution-specific extensions.

Polling and capacity

Public SilverLake rate limits were not verified. Confirm request, concurrency, response-size, timeout, maintenance-window, and batch-window limits. Use bounded concurrency and backoff.

Incremental synchronization

Confirm support for date filters, modified timestamps, sequence numbers, continuation tokens, or other watermarks. Persist checkpoints and design replay behavior before enabling scheduled retrieval.

Idempotency and reconciliation

Identify request identifiers and safe retry behavior for every state-changing operation. Do not automatically retry postings or other financial writes when the remote result is unknown; route them to reconciliation.

Testing and monitoring

Test representative XML payloads, SOAP faults, schema changes, duplicate messages, timeouts, and partial failures in a non-production environment. Monitor workflow outcomes without exposing sensitive payloads.

Why use Martini instead of scripts or point-to-point integrations?

Centralized orchestration

Martini provides a maintainable workflow layer between SilverLake and enterprise applications, coordinating SOAP calls, validation, enrichment, downstream writes, and exception paths.

Controlled API access

Martini can expose a controlled REST API so consuming applications do not need direct access to jXchange. The façade can enforce authorization, field filtering, consistent responses, and business rules.

Reusable transformations

Explicit mappings isolate SilverLake XML schemas from downstream models and make changes easier to test, version, and reuse across applications.

Operational reliability

Compared with isolated scripts, Martini centralizes secure configuration, scheduling, retries, logging, correlation, and reconciliation patterns for institution-specific integrations.

Frequently asked questions

How can Jack Henry SilverLake be integrated with enterprise systems?

SilverLake is generally integrated through institution-provisioned Jack Henry interfaces, most notably jXchange SOAP/XML services where available. The institution must provide the applicable WSDLs, endpoints, credentials, certificates, permissions, and operation list. Scheduled polling, approved callbacks, or file exchange may be used when specifically supported, but a public SilverLake REST API and general webhook platform were not confirmed.

Can Martini integrate with Jack Henry SilverLake?

Yes. Martini can integrate with SilverLake by consuming institution-approved jXchange SOAP services, transforming XML into controlled downstream formats, orchestrating multi-step workflows, exposing REST APIs, scheduling synchronization, and handling validation, retries, logging, and reconciliation. The exact integration depends on the financial institution’s licensed services and environment.

Do I need a connector to integrate Jack Henry SilverLake with Martini?

No. A dedicated Jack Henry SilverLake connector is not required. Martini can use the confirmed native integration mechanism—normally institution-provisioned jXchange SOAP/XML services—and can also use a specifically approved callback or file process if one is provided. A native Martini connector was not verified in the supplied research.

Is there any extra Lonti cost to integrate Jack Henry SilverLake with Martini?

Lonti does not charge an additional per-connector or per-vendor fee to integrate Jack Henry SilverLake. The integration is subject to the provisioned capacity of the Martini environment. Separate costs may apply from Jack Henry, the financial institution, cloud infrastructure, certificates, network services, or other third parties depending on the licensed interface and deployment model.

Which Jack Henry SilverLake integration method should be used?

jXchange SOAP/XML is the primary mechanism to investigate because it is associated with Jack Henry core integrations. A SilverLake-specific REST or GraphQL interface was not confirmed, and GraphQL should not be assumed. The institution should validate service operations, WSDL versions, security requirements, and permissions before selecting the final design.

Does SilverLake support webhooks or event notifications?

A general-purpose SilverLake webhook mechanism was not confirmed. Event coverage should not be assumed for customer, account, loan, or transaction changes. If no approved event or callback product is available, Martini can run scheduled polling workflows using supported service operations and reliable incremental criteria.

How does synchronization and data mapping work?

Martini can retrieve approved SilverLake data, map SOAP/XML structures into canonical JSON or target application models, apply validation and business rules, and write to downstream systems. Incremental synchronization depends on whether the available operation supports date ranges, modified timestamps, sequence numbers, continuation tokens, or another watermark mechanism.

How are errors, retries, and duplicate financial operations handled?

Martini can handle SOAP faults, validation errors, timeouts, logging, retries, and reconciliation workflows. State-changing operations should not be retried automatically until their idempotency and unknown-outcome behavior are confirmed. Correlation identifiers, request identifiers, bounded backoff, duplicate detection, and manual review may be needed for financial operations.
