Mparticle

mParticle is an enterprise Customer Data Platform with a strong focus on identity resolution — stitching together customer data across devices, sessions, and channels into unified customer profiles. For agents in enterprise data infrastructure, mParticle's server-side events API enables event ingestion directly from backend services and agents, bypassing client-side collection. The identity management capabilities are a distinctive enterprise feature: agents can contribute to the unified customer identity graph alongside client-side data.

Authentication uses API key and secret pairs for the server-side API. The key/secret pair is used for request signing rather than simple bearer token auth — agents must sign requests appropriately. Teams integrating mParticle should use the official SDKs where available to handle request signing correctly, or implement the signing algorithm carefully for direct HTTP integration.

Documentation covers the server API with appropriate depth for enterprise integrations. The identity management documentation explains the identity priority and resolution model clearly, which is necessary for correctly attributing server-side events to customer profiles. Teams building enterprise customer data pipelines with agent-generated events will find the documentation thorough.

The Server API covers event batching, user attribute updates, and identity management. The batch event submission model is important for server-side integrations — events are submitted in batches for efficient processing rather than one-at-a-time, which is the appropriate pattern for agent-generated event data. The identity API enables agents to associate backend events with the correct customer profiles using available identifiers (email, customer ID, device IDs).

Reliability is enterprise-grade for production customer data infrastructure. mParticle maintains the data durability guarantees appropriate for customer data that feeds downstream analytics, advertising, and marketing platforms where data loss has direct revenue impact.
