Integration with IBM Sterling Intelligent Promising for enhanced pre-purchase experience

Sterling™ Intelligent Promising delivers intelligent omnichannel fulfillment through modular, cloud-native services that enable accurate order promising, real-time inventory visibility, and optimized fulfillment decisions.

You can integrate IBM® Sterling Selling and Fulfillment Suite with IBM Sterling Intelligent Promising for pre-purchase capabilities like Get EDD and Get Checkout Shipment Plan by synchronizing inventory availability into SIP.

Integrating with Sterling Intelligent Promising for pre-purchase

In this integration, inventory changes that are identified by Realtime Availability Monitor (RTAM) in Order Management System are synchronized to IBM Sterling Intelligent Promising asynchronously. IBM Sterling Intelligent Promising then uses this inventory information to support pre-purchase experiences such as estimated delivery dates and sourcing decisions.

Enabling integration with Sterling Intelligent Promising for pre-purchase

To enable this integration, configure the properties:

sip_integration.promising.syncNodeAvailability.enable
sip_integration.promising.syncNodeAvailability.impl

Additionally, following properties are used by the integration and are set by default to required value:

sip_integration.promising.baseUrl
sip_integration.promising.nodeAvailability.service
sip_integration.promising.nodeAvailability.apiUrl

These properties define the SIP base URL and the service/API configuration used by the integration.

Syncing the availability

The sync happens only when Real Time Availability Monitor (RTAM) raises event REALTIME_AVAILABILITY_CHANGE_LIST and can be triggered as part of below processes:

RTAM Full Sync
RTAM Activity Sync
RTAM Quick Sync
monitorItemAvailablity API

To sync the availability, IBM Sterling® Order Management System provides an interface com.yantra.shared.sip.SIPNodeAvailabilitySync that is used to publish information related to node availability events. A default reference implementation, com.ibm.iv.adapter.SIPNodeAvailabilitySyncDefaultImpl is provided out-of-the-box as part of the integration.

This interface is configured via the sip_integration.promising.syncNodeAvailability.impl property.

By overriding this property, a custom implementation of the interface can be plugged in to handle extended node availability synchronization as required. The specified class must implement the interface com.yantra.shared.sip.SIPNodeAvailabilitySync.

To update the availability in SIP, this integration uses the Define node inventory availability API in IBM Sterling Intelligent Promising:

PUT /promising/{tenantId}/v1/availabilityWindows/nodes/{nodeId}

Note:

This integration does not support advanced inventory dimensions and use cases, such as:
- Segment-specific inventory
- Tag-specific inventory
- Availability synchronization is performed asynchronously and does not interfere with RTAM transactional processing. Any errors that occur during the synchronization are logged for reference, but they do not cause the RTAM process to fail.
The integration assumes the configurations required for IBM Sterling Intelligent Promising API have been done prior to executing this step. For more information, see Promising service.

Validations for availability sync to Sterling Intelligent Promising

In addition to the configured properties, the integration verifies certain runtime conditions before synchronizing node-level inventory availability to IBM Sterling Intelligent Promising. These conditions include:

Valid client information

SIP Integration Adapter has valid tenantId, clientId and secret information.
IV_INTEGRATION_PHASE

The rule IV_INTEGRATION_PHASE should be 0.0.

When iv integration is enabled (IV_INTEGRATION_PHASE >0), availability is already synced to Sterling Inventory Visibility and any further synchronization to other systems is expected to happen through Sterling Inventory Visibility.
REALTIME_ATP_MONITOR.REALTIME_AVAILABILITY_CHANGE_LIST

The IBM Sterling Order Management System event, REALTIME_ATP_MONITOR.REALTIME_AVAILABILITY_CHANGE_LIST must be enabled.

If these conditions are not met, the sync is skipped.
