Although these APIs are publicly documented, the management of Event Subscriptions is currently handled by Heuristics staff due to the complex templating that is involved.

Overview

Publisher data is not publicly accessible to prevent it from being scraped, and to give Publishers controls over their data.

Therefore, Subscribers must “subscribe” to a Program in order to pull its data from the Hub.

Heuristics staff establish these relationships partially to manage the complex templates that are required, but also to ensure that the Subscriber has a legitimate need to access that Publisher’s data.

Data model

SUBSCRIPTION

A Subscription is a relationship from a Subscriber to a Publisher that allows the Subscriber to receive the Publisher’s data.

Field

Type

Notes

ProgramId

string (25 char)

The identifier of the Subscriber

PublisherProgramId

string (25 char)

The identifier of the Publisher

LastSyncUtc

UTC date/time

UTC timestamp of the last time the Subscriber pulled data from this Publisher

SyncEnabled

boolean

Whether or not the subscription supports the nightly sync process. (LB subscribers only)

Setting this to TRUE does not automatically enable the nightly sync, it just allows the nightly sync to process this subscription.

LbApiPayloadTemplate

string

Handlebars template that will convert the Publisher’s EventData into a payload for LearningBuilder’s WorkflowImportQueue/CreateBatch API.
