MoEngage

Subsets supports syncing data to MoEngage using the bulk customer import endpoint. Each call carries a batch of customer updates. Subsets fetches campaign details from the Email Campaign Details core-services/v1/campaigns/search endpoint to link campaigns to experiments.

The following customer attributes are created on each user in MoEngage:

{
  'subsetsExperimentId',
  'subsetsExperimentName',
  'subsetsExperimentAddedAt',
  'subsetsSubscriberChurnRisk',
  'subsetsExperimentAssignment'
}

Authentication

MoEngage uses dual authentication on every request:

1. Basic Auth header — Authorization: Basic base64(workspace_id:api_key)
2. App key header — MOE-APPKEY: {app_id}

Customer export uses the Data API key as the Basic Auth password; campaign lookups use the Campaign API key.
