ExistenceGOODFour documented API surfaces: Engage, Feedback, Web Agent, and the Aggregation API behind Pendo's own charts.
AccessGOODSelf-serve with no partner approval; integration keys are created in Settings. Bulk warehouse export is a paid add-on.
CoverageGOODVisitors, accounts, events, guides, segments, and aggregations; large exports hit 4GB and 5-minute caps.
AuthMIXEDStatic non-expiring integration key with only a read or write bit; no OAuth or scoped tokens, though keys are self-serve in settings.
Docs & DXGOODPublic docs, SDKs for every major web and mobile framework, and an MCP server for AI clients.

SOURCES
Authentication is a single static integration key (x-pendo-integration-key header), no OAuth, no expiration, no scoped tokens, no per-endpoint permissions beyond read/write; rotation must be enforced manually stitchflow.com ↗
Undocumented but enforced ceiling of 100 requests/sec to any single API endpoint per integration key, HTTP 429 returned silently when exceeded stitchflow.com ↗
Aggregation API response sizes hard-capped at 4GB and a 5-minute server-side timeout, large historical exports fail with no streaming or cursoring stitchflow.com ↗
Aggregation pipeline has 'undocumented result-size limits' for very large datasets, Pendo's own recommendation is to use Data Sync (paid add-on) instead of the public API for bulk extraction stitchflow.com ↗
API timeouts are common enough that Pendo maintains a dedicated support article on them, implies routine throttling/degradation at scale support.pendo.io ↗
Data Sync (the only reliable bulk-export path) is a paid add-on SKU separate from the analytics tier, real-time programmatic access to your own event stream is not in the standard plan support.pendo.io ↗
Engage API and Feedback API are documented on separate subdomains (engageapi.pendo.io, feedbackapi.pendo.io) with inconsistent shape and authentication coverage between them pendo.io ↗
Lost integration keys cannot be recovered, rotation requires re-credentialing every downstream integration support.pendo.io ↗
Aggregation API requires customers to construct nested JSON pipeline queries (Pendo Aggs) by hand, steep learning curve, easy to mis-shape and trigger 4GB/5-min timeouts developers.pendo.io ↗
Native mobile SDK API documentation is fragmented across the developer portal, support center, and per-framework GitHub repos with inconsistent coverage support.pendo.io ↗
Quote-only pricing, no public rate card, every paid plan says 'Request pricing' and requires sitting through a 45-minute sales demo to get a number userguiding.com ↗
MAU-based pricing scales 3-4x as your product grows; Vendr median is ~$48,500/yr, enterprise commonly $120,000/yr with mandatory 3-year terms ($360K TCV) vendr.com ↗
MAU overages billed at roughly double renewal rate and Pendo does not notify customers in-term, customers must self-monitor to avoid surprise bills support.pendo.io ↗
Annual auto-renewal price hikes routinely 5-20%; customers report needing multi-year contracts just to cap escalators quackback.io ↗
No monthly billing, annual contracts only, and the free tier is capped at 500 MAU which is too low for most real products pendo.io ↗
Data accuracy is among the top 5 most-cited complaints across 1,489 G2 reviews userguiding.com ↗
Guide builder and reporting UI are widely described as fragmented, slow, glitchy, and 'hard to navigate'; steep learning curve userguiding.com ↗
'Contract negotiation feels like a court settlement', multiple meetings, opaque concessions, lock-in language oreateai.com ↗
Manual page/feature tagging creates ongoing maintenance overhead vs. autocapture-first competitors like Heap contentsquare.com ↗
Post-login focus misses upstream marketing/acquisition friction; bundled platform charges for capabilities (roadmaps, feedback, guides) that many teams don't need contentsquare.com ↗
