SCORECARD

ExistenceGOODA public REST API with v1.0 and v2.0 versions is documented on readme.io, including a machine-readable llms.txt index.
AccessMIXEDFull API and webhooks require the Unlimited plan at $149 per user per month; lower tiers get Zapier and native connectors.
CoverageGOODThe API spans the operational model: items, BOMs, stock lots, manufacturing, customer and purchase orders, shipments.
AuthMIXEDStatic HTTP Basic with a long-lived api-key and access-key pair; no OAuth, so vendors hold permanent credentials.
Docs & DXMIXEDDocs live on readme.io and webhooks exist, capped at 5 per account on status events; support will not help with API issues.
StabilityMIXED
Supergood: MRPeasy has an API, with gaps. We cover what it's missing: stable endpoints, normalized JSON, managed auth.

SOURCES
Full REST API and webhooks are paywalled behind the top-tier Unlimited plan ($149/user/month), Starter, Professional, and Enterprise customers cannot programmatically access their own operational data without upgrading the entire seat count mrpeasy.com
Webhooks are capped at 5 total per account and cover only a narrow set of object/event types (Customer Order, Manufacturing Order, Purchase Order, Shipment status; Payment status where applicable), large swaths of operational changes (BOM edits, stock adjustments, lot QC decisions, employee time entries) require polling mrpeasy.com
Authentication is static HTTP Basic with a long-lived api-key + access-key per account, no OAuth flow, which forces brands to share permanent credentials with third-party vendors and complicates multi-tenant SaaS integrations mrpeasy.readme.io
MRPeasy's Support Department explicitly will not help with API issues and requires customers to engage their own "highly qualified software development partner," creating a real services tax on programmatic access mrpeasy.readme.io
Zapier integration coverage is described by users and competitors as limited compared to Katana or NetSuite, many real-world automations fall back to raw REST API work g2.com
Bulk reporting and export are weak in-product, users routinely build external dashboards and BI pipelines (Power BI, Tableau, Google Sheets, Snowflake via Omnata/Portable) on top of the REST API just to get their own data out at scale portable.io
EDI is not native, companies needing supplier/customer EDI must layer third-party middleware (e.g., Crossfire) on top of the REST API, adding cost and complexity crossfireintegration.com
Maintaining two parallel API versions (v1.0 and v2.0) means partners must read carefully which endpoints/fields exist in each, some object types and features are only on one version, creating migration and feature-parity friction mrpeasy.readme.io
Bi-directional accounting sync with QuickBooks Online and Xero is reported to occasionally break (auto-sync failing on invoices), affected customers turn to API extraction + custom reconciliation outside MRPeasy trustpilot.com
Native reporting and analytics are shallow, users routinely report needing to export to Google Sheets or BI tools for advanced reporting, trend analysis, COGS roll-ups, and bottleneck analysis g2.com
Customization options are restricted, limited ability to tailor fields, workflows, dashboards, or document templates for non-standard manufacturing models getapp.com
Costs rise quickly with additional users and advanced features, API, webhooks, B2B portal, and Approval System are paywalled across tiers, pushing real-world deployments toward $99-$149/user/month mrpeasy.com
Auto-sync with invoices (Xero/QuickBooks Online) reportedly breaks, requiring manual syncing; support unable to provide root-cause fixes trustpilot.com
Stock does not decrement at manufacturing-order release, only at MO completion, creating planning blind spots during in-flight production g2.com
Support is ticket/email only with no phone option; some users report generic or templated responses that don't resolve complex configuration questions trustpilot.com
Zapier connection is described as limited, fewer triggers/actions than competitors, forcing custom REST API work for many real workflows g2.com
Integration capabilities are narrower than enterprise ERPs, gaps for EDI, advanced 3PL, shop-floor IoT, and certain regional accounting systems force third-party middleware (Crossfire, Make, Tulip, Omnata, Portable) crossfireintegration.com
UI is functional but considered "basic" by reviewers compared to Katana's polish, limited ability to control how data is displayed in lists and dashboards capterra.com
MRPeasy's Support Department explicitly states it cannot help with using the API, customers must have their own "highly qualified software development partner" to use API/webhooks mrpeasy.readme.io
