Essential Pre-Built Connectors for Facilities & PropTech Tech Stacks

Facilities and real estate operations require seamless data flows across a variety of systems. Key pre-built connectors link CMMS (work order), ERP/finance, CRM/ticketing, IoT/energy, and tenant experience platforms into unified workflows.

This report identifies the high-impact connectors for an FM/PropTech stack. Must-have connectors include CMMS APIs (FMX, JLL Corrigo, Nuvolo on ServiceNow), ERP systems (SAP, Oracle, Yardi, MRI), and CRM/ticketing (Salesforce, Zendesk). High-value connectors cover areas like procurement (Coupa/Ariba), property management data (Yardi/MRI for leases/payments), and IoT sensors (Samsara, Monnit, Zonar).

We map each to common workflows – e.g. an inspection alert from Zonar creating an FMX work order, or a lease in Yardi triggering invoice entries. We also cover technical requirements (auth methods, rate limits), deployment modes (cloud vs on-prem gateways), operational needs (monitoring, retries, SLAs), and security (OAuth2, token vaults).

Each capability is addressed by ConnectorHub’s integration platform: it provides out-of-the-box connectors for these systems along with multi-tenant security, monitoring, and data mapping. Finally, we offer actionable recommendations and a prioritized connector checklist for FM/PropTech outsourcers.

Connector Priority and Common Workflows

Pre-built connectors should be prioritized by impact on core FM workflows:

Must-Have (Tier 1):

CMMS – FMX, Corrigo, Nuvolo: These connect work order management. For example, a failed equipment inspection in Zonar (fleet telematics) auto-creates an FMX work request
. Nuvolo (on ServiceNow) manages the full asset life-cycle and tenant service requests. These connectors handle work order creation, status updates, and attachments.

ERP/Finance – SAP, Oracle ERP, Yardi, MRI: These handle billing, purchase orders, asset accounting and lease data. They enable synchronization of procurement and financial data. E.g., an FMX purchase order can update inventory in SAP, or a Yardi lease renewal can generate an accounting entry.

CRM / Ticketing – Salesforce Service Cloud, Zendesk: Tenant requests often originate here. Integrations pull helpdesk tickets into CMMS or push CMMS status back to tenants. Salesforce APIs (SOAP/REST with OAuth) and Zendesk’s REST API can be connected to synchronize contacts, cases, and work order statuses.

High-Value (Tier 2):

Property Management Systems – Yardi, MRI: Beyond ERP, these handle leasing, resident accounts and facility billing.

Their connectors can automate tenant billing and sync maintenance requests. For example, Supergood’s Yardi API supports creating leases and generating work orders from service requests
.
IoT/Energy Platforms – Samsara, Monnit, Honeywell, Schneider Electric: These feed real-time alerts. Connectors ingest sensor data (e.g. HVAC anomalies or energy meters) and trigger CMMS workflows. A predictive maintenance use case might trigger a Nuvolo work order when a sensor breaches thresholds
.
Tenant Experience Platforms – BuildingLink, HqO, etc.: While proprietary, tenant portals or mobile apps connect to the integration layer, often via the CRM or custom API.
Integrations push tenant service requests into FM systems and send updates back. For example, a tenant-submitted ticket in a mobile app could become a CMMS work order.

Nice-to-Have (Tier 3):

*Vendor/Supplier Systems *– Coupa, Ariba, QuickBooks, Bill.com: Automate procurement flows. For example, FMX purchase orders could create Coupa requisitions.

Building Systems – BMS/BAS (BACnet, Niagara), Access Control: Specialized IoT connectors that feed equipment status or building alarms (e.g. NACOP, Johnson Controls) into work orders.

Analytics & Reporting – BI Tools (PowerBI, Tableau): Data connectors for dashboards; often via the ERP->CMMS connectors.

These connectors map directly to FM workflows:

Work Orders: CMMS connectors (FMX/Corrigo/Nuvolo) to create/update tasks.
Billing/Procurement: ERP connectors (SAP/Oracle/Yardi) to post POs, invoices.
Tenant Requests: **CRM/Ticket connectors (Salesforce/Zendesk) for service tickets.
**Asset Lifecycle: Property management (Yardi/MRI) and CMMS connectors to sync asset data and maintenance histories.
Energy/Alerts: IoT connectors (Samsara/Monnit) for sensor events triggering CMMS jobs.

This mapping ensures end-to-end flows (e.g. inspection → work order → invoice → account reconciliation) are automated. For example, linking Zonar to FMX “ensures every failed inspection automatically generates a work order” and centralizes vehicle maintenance data

Technical Requirements and API Characteristics
Critical technical considerations for these connectors include:

Authentication:

• FMX (REST API): Uses HTTP Basic Auth (Base64-encoded “email:password” header)

• Requires creating a dedicated API user in FMX with proper permissions.
  Corrigo Enterprise: Uses OAuth2 for secure token-based access

• Salesforce/Zendesk: OAuth2 (Salesforce) or OAuth/Token (Zendesk) with configurable scopes.
  SAP/Oracle: Typically OAuth2 or SAML (for cloud editions), or legacy user credentials for on-prem.

• Yardi/MRI: May require API tokens or SSO credentials. (Supergood’s Yardi API even handles MFA via OAuth)

.Rate Limits & Throttling:
Public docs typically outline API limits (e.g. Salesforce ~250k calls/day, etc.). Connectors should respect these. If not specified (e.g. FMX), assume sensible limits to avoid lockouts. Implement exponential backoff.

Data Formats & Models:
All major platforms use JSON for REST APIs. Each has its own data schema (e.g., FMX has “WorkRequests”, “PurchaseOrders”
; Yardi has “leases”, “workorders”). Pre-built connectors encapsulate mapping between these schemas. For generic connectors, supporting JSON schema or Swagger/OpenAPI is essential.

Webhooks & Event Subscriptions:
Real-time triggers improve responsiveness. Corrigo supports webhooks (event-based pushes). FMX does not natively push; one would poll or use scheduled syncs. If available, connectors should subscribe to events (e.g. new work request created).

E.g.

• FMX: No public webhooks – relies on API polling or scheduled calls.
• Corrigo: Official webhook/events API allows receiving updates.
• Salesforce: Supports Platform Events and streaming APIs for real-time updates.
• Zendesk: Webhooks for ticket events.
• IoT: Platforms often push MQTT or Webhook events that connectors can ingest.

Deployment (On-Prem vs Cloud):

• Cloud SaaS: Most connectors are cloud-based and communicate over HTTPS. SAP or Oracle cloud products have public endpoints.

• On-Premises Systems: On-prem CMMS or ERP may require an agent or VPN. For example, connecting to an on-site SAP ERP would use a secure tunnel or on-prem “edge” connector to reach the cloud iPaaS without exposing internal systems.

-Hybrid: Many outsourcers run hybrid. ConnectorHub supports both with optional on-prem agents if needed. (Most FM APIs like FMX and Corrigo are cloud-hosted.)

Operational Considerations:

• Monitoring & Observability: Integrations should log each API call and error. Platforms like ConnectorHub provide dashboards and notifications for failed syncs.
• Error Handling & Retries: As with any integration, transient failures must be retried. E.g. if a CMMS API call times out, the connector should automatically retry or queue the request. If an API returns a 4xx error, it should alert operators.
• **SLAs: **Ensure the connector meets business SLAs. For critical flows (e.g. tenant requests), aim for sub-minute end-to-end latency. Monitoring alerting on missed SLAs is recommended.
• Versioning: API versions change. Use versioned endpoints when possible, and keep connectors updated to avoid breaking changes.

Security & Compliance:

• OAuth2 and Token Vaults: Store credentials (API keys, tokens) securely. ConnectorHub, for instance, encrypts all credentials and supports fine-grained role-based access for each connector account.
• Encryption: All data in transit must use HTTPS/TLS. Sensitive data (like tenant PII) should also be encrypted at rest in the integration layer.
• Tenant Isolation: In multi-client environments, ensure connectors do not cross data between clients. Each customer’s connectors and credentials should be isolated in the integration platform.
• Compliance: Verify that connectors and data flows comply with relevant standards (SOC2, GDPR, HIPAA as needed). Using official APIs helps; avoid screen-scraping or “unofficial” methods in regulated contexts.

ROI/Impact:
Pre-built connectors drastically cut development time. An industry study noted that IoT integration (sensors to maintenance) can reduce energy costs by 15–30% and improve uptime
. Automating just the invoicing workflow between CMMS and ERP can save thousands of staff hours annually. For example, a ConnectorHub customer reported 50% less admin work after connecting Corrigo to their business system
. Though exact ROI depends on context, the impact on operational efficiency is well-documented.

Connector-to-Workflow Mapping

Below is a conceptual mapping of key connectors to FM/PropTech workflows (see also the flowchart):

1. Tenant App ➜ ConnectorHub ➜ CMMS/CRM: A mobile tenant request app or portal sends a request (e.g. a maintenance ticket) to ConnectorHub. ConnectorHub uses the Salesforce or Zendesk connector to create a case, and the CMMS connector (FMX/Corrigo/Nuvolo) to generate a work order. Status updates flow back to the tenant app via the CRM. This automates the “tenant request ➜ work order” loop.
2. CMMS ➜ ConnectorHub ➜ ERP: Upon work order completion, the CMMS connector exports cost and parts usage, and ConnectorHub pushes a purchase invoice or cost record into SAP/Oracle/Yardi. This connects maintenance to finance for billing and asset accounting.
3. **IoT ➜ ConnectorHub ➜ CMMS: **IoT sensors (via Samsara or Monnit) detect anomalies (e.g. high temperature). The IoT connector in ConnectorHub ingests the alert (possibly via MQTT or REST webhook) and instantly creates a maintenance ticket in CMMS, enabling condition-based maintenance
4. ERP ➜ ConnectorHub ➜ CMMS: A change in asset status in ERP (e.g. commissioning a new machine in SAP) can sync to CMMS equipment lists. A ConnectorHub SAP/Oracle connector listens for asset updates and populates the CMMS data.
5. CRM ➜ ConnectorHub ➜ CMMS: Customer issue recorded in Salesforce (CRM) triggers a maintenance task. ConnectorHub’s Salesforce connector reads the case and uses the CMMS connector to log a corresponding work request, uniting customer service with facilities response.

ConnectorHub’s Pre-Built Connectors Address
ConnectorHub provides pre-built connectors for all the systems above. Each critical capability is covered:

Work Orders/CMMS: ConnectorHub includes connectors for FMX, Corrigo, and ServiceNow/Nuvolo (leveraging ServiceNow’s CMDB/work order API). This automates the “maintenance request” and “asset data” flows.
ERP/Finance: It offers SAP and Oracle connectors (via OData/REST) and Yardi/MRI connectors for property/finance data. These cover invoicing, purchase orders, and lease payments.
CRM/Ticketing: **Built-in connectors for Salesforce and Zendesk handle tenant and service tickets. ConnectorHub’s workflow designer links them to CMMS tickets and email/SMS notifications.
IoT/Energy: Connectors for Samsara, Monnit, and generic IoT hubs allow ingest of sensor events. ConnectorHub can transform those into actionable CMMS tasks.
**Data Transformation & Security: Its platform-level features (data mapping, OAuth token management, encryption, RBAC) ensure each integration is secure and data is consistent across systems, without custom coding. For example, ConnectorHub encrypts all API keys and isolates each customer’s data, meeting enterprise compliance requirements.
By covering these systems, ConnectorHub’s platform streamlines FM processes. Instead of building custom scripts, FM outsourcers can deploy these vetted connectors to achieve end-to-end integration: work orders, billing, tenant support, and IoT events all flow through one unified layer.

Recommendations and Connector Checklist

For facility management and PropTech integration projects:

1. Adopt Key Integrations First: Prioritize connectors that feed core workflows. Ensure CMMS, ERP, and tenant support systems are connected. A minimal set includes FMX (or Corrigo/Nuvolo), SAP/Oracle, and Salesforce/Zendesk.
2. Use Standard Auth: Configure each connector with secure credentials. FMX uses Basic Auth
3. others like Salesforce use OAuth2 tokens. Store these in a secure vault.
4. Leverage Scheduling & Webhooks: Where possible, enable webhooks (e.g. in Corrigo) or schedule frequent syncs. This ensures data stays current (e.g. sync asset inventories nightly).
5. Monitor & Test: Implement end-to-end monitoring. For example, verify each new CMMS work request from a tenant app is received in CRM and triggers the right workflow. Use dashboards/alerts on ConnectorHub to watch for failures.
6. Plan for Scale: If clients have on-prem systems, plan edge agents or VPNs. Use multi-tenant isolation to onboard new customers on the fly.
7. ROI Focus: Estimate efficiency gains (reduced manual entry, faster resolution). For instance, automating just the Zonar→FMX flow prevents lost maintenance tickets . Track these benefits. Connector Priority Checklist:

• Tier 1 (Essential): FMX or Corrigo, Salesforce, SAP/Oracle, Zendesk.
• Tier 2 (High-Value): Nuvolo (ServiceNow), Yardi/MRI, Samsara/Monnit.
• Tier 3 (Nice-to-Have): Coupa/Ariba (Procurement), Slack (Ops communication), specialized IoT/BAS.

By deploying these pre-built connectors, FM outsourcers can rapidly integrate their tech stack. This transforms siloed processes into automated pipelines — for example, automatically generating invoices when work orders close, or sending alert texts to technicians from CRM cases. A well-architected integration layer (like ConnectorHub) ensures each of these pieces fits together securely and reliably.
