5 best platforms to connect AI agents to enterprise software (2026)

Enterprise SaaS and AI-agent integrations with systems such as NetSuite, SAP, ServiceNow, Workday, and Dynamics 365 often require support for tenant-specific custom objects, permissions, business rules, large backfills, API limits, and separate customer configurations. The comparison evaluates Nango, Merge, Paragon, Prismatic, and Apideck based on extensibility, synchronization reliability, missing API support, onboarding, deployment options, and volume-based costs. Nango is positioned for deeply customized integrations with managed execution, reusable code, customer-specific metadata, and self-hosting or BYOC options, while Merge and Apideck emphasize unified HRIS and accounting models, Paragon combines visual workflows with code, and Prismatic focuses on configurable per-customer deployments and private-network connectivity. The discussion also stresses verifying actual endpoint coverage and testing customized customer tenants before adoption, including custom-field access, authentication, pagination, interrupted sync recovery, credential rotation, and rate limits. Platform selection should account for each enterprise application’s distinct API architecture, such as NetSuite REST, SuiteQL, and SOAP; SAP product-specific OData APIs; ServiceNow Table API and Integration Hub; Workday SOAP, REST, and RaaS; and the separate APIs used across Dynamics 365 products.
