mParticle Platform Help

Step 1 — Gather context

If references/learnings.md exists, read it first for accumulated platform knowledge.

1. What's your situation?

   • A) Setting up mParticle for the first time
   • B) SDK or API integration issues (events not sending, errors)
   • C) Identity resolution problems (wrong merges, duplicate profiles)
   • D) Audience/segmentation not working as expected
   • E) Connection to a destination failing or delayed
   • F) Data planning / schema validation issues
   • G) Privacy / DSR / compliance questions
   • H) Pricing, plan limits, or cost optimization
   • I) Migrating to/from mParticle
   • J) Other — describe it

2. Which APIs/SDKs are you using?

   • A) Web SDK
   • B) Mobile SDK (iOS, Android, React Native, Flutter)
   • C) Events HTTP API (server-side)
   • D) Platform API (account/workspace management)
   • E) Profile API (querying user profiles)
   • F) Data Planning API
   • G) IDSync API
   • H) Not sure / haven't started yet

3. What's your mParticle pod?

   • A) US1 (default)
   • B) US2
   • C) EU1
   • D) AU1
   • E) Not sure

Skip-ahead rule: if the user's prompt already contains enough context, skip to Step 2.

Step 2 — Route or answer directly

| Problem domain | Route to | |---|---| | Choosing between CDPs (mParticle vs Segment vs others) | /sales-cdp {user's question} | | CRM data dedup without a CDP | /sales-data-hygiene {user's question} | | Connecting mParticle to email platforms | /sales-integration {user's question} | | Retargeting with mParticle audiences | /sales-retargeting {user's question} | | Contact enrichment before feeding to mParticle | /sales-enrich {user's question} |

When routing, provide the exact command.

Step 3 — mParticle platform reference

Read references/platform-guide.md for the full platform reference — modules, pricing, integrations, data model, API overview, workflows.

Read references/mparticle-api-reference.md for detailed API endpoints, authentication, request/response formats.

Answer the user's question using only the relevant section. Don't dump the full reference.

Step 4 — Actionable guidance

You no longer need the platform guide — focus on the user's specific situation.

Quick decision framework:

• First-time setup: Start with one data source (web or mobile SDK) → one destination. Get events flowing end-to-end before adding more sources.
• SDK issues: Check pod-specific endpoint, API key/secret pair, and that the SDK is initialized before logging events.
• Identity problems: Review your Identity Strategy in the dashboard. Test with /identify endpoint before relying on automatic resolution.
• Audience sync delays: Connections can take up to 48 hours on initial setup. Check connection status in the dashboard. Real-time forwarding ≠ real-time destination processing.
• Cost optimization: Monitor event volume in Usage dashboard. Use Data Plans to filter noise events before they count toward billing.

If you discover a gotcha, workaround, or tip not covered in references/learnings.md, append it there.

Gotchas

Best-effort from research — review these, especially items about plan-gated features and integration gotchas that may be outdated.

1. Connection setup can take up to 48 hours — the UI shows "connected" but backend provisioning may still be running. Only a CSM will tell you this; it's not documented in-product.

2. Calculated attributes are very basic — no multiply, divide, or arithmetic operations. If you need complex computed fields, do them in your warehouse and sync back.

3. Token expiry is 8 hours with no revocation — Platform/Profile API OAuth tokens can't be revoked, only expire. Cache them and refresh proactively; initial token requests take 1-3 seconds.

4. Pod-specific endpoints are required — using the wrong regional endpoint (US1 vs US2 vs EU1 vs AU1) silently drops events. Verify your pod in Workspace Settings.

5. Bulk events endpoint accepts up to 100 batches — but returns 202 even if individual batches fail. Validate batch structure before sending; check quarantine for failures.

6. Events API rate limit is 250 events/sec — contact support for higher limits. No self-serve rate limit increases.

7. Profile API has 15 RPS limit — intended for testing, not production. Implement a backend personalization service as intermediary.

8. No self-serve pricing — enterprise-only, typically $40K-$375K+/year (avg ~$156K). Now uses value-based pricing (VBP) with "mParticle Credits" consumed by event volume (Connect/Preserve/Personalize tiers), profile/feature usage, storage, and real-time audiences. mParticle merged with Rokt (~$300M, announced Jan 2025) — now branded "mParticle by Rokt."

Examples

Example 1: Events not reaching destination

User says: "I set up a Facebook connection in mParticle but no events are showing up in Facebook" Skill does: Checks connection status (may take up to 48 hours), verifies pod-specific endpoint, confirms data filter settings aren't blocking the events, reviews connection configuration for correct Facebook credentials. Result: User identifies that the connection was still provisioning and events flow after backend setup completes.

Example 2: Identity resolution merging wrong profiles

User says: "mParticle is merging two different customers into one profile because they shared a device" Skill does: Reviews Identity Strategy configuration, explains deterministic vs probabilistic matching, recommends switching to a stricter strategy that prioritizes authenticated identifiers over device IDs. Suggests testing with the /identify and /search endpoints. Result: User adjusts their Identity Strategy to prevent false merges from shared devices.

Example 3: Server-side event ingestion

User says: "How do I send purchase events from my backend to mParticle?" Skill does: Walks through Events API setup — pod-specific endpoint, Basic auth with API key/secret, batch structure with commerce events, product actions. Recommends using /v2/bulkevents for efficiency and explains the 128KB batch size limit. Result: User has working server-side event ingestion with proper authentication and batch formatting.

Troubleshooting

Events API returning 403

Symptom: Server-side events return 403 Forbidden Cause: Wrong API key/secret pair, or using Platform API credentials instead of Events API credentials Solution: Events API uses separate credentials from the Platform API. Go to Setup > Inputs > select your platform > copy the API Key and Secret specifically for that input. Use Basic auth, not OAuth.

Audiences not syncing to destination

Symptom: Audience created in mParticle but destination shows no members Cause: Connection provisioning delay, data filter blocking audience attributes, or destination credentials expired Solution: Check connection status (allow up to 48 hours for new connections). Verify data filters aren't blocking user attributes or identities the destination needs. Re-authenticate the destination connection if credentials expired.

Data Plan validation rejecting valid events

Symptom: Events quarantined even though they look correct Cause: Schema mismatch between Data Plan version and actual event structure — often a property type mismatch or missing required field Solution: Check quarantine for specific validation errors. Compare your event payload against the Data Plan's JSON Schema. Use the /validate endpoint to test batches before sending. Rate limits: 3,000 req/min per account, 6,000 req/min per org.
