Marker.io API

marker.io

No public REST API exists; it is the top-voted request on Marker.io's own feedback portal. What ships today is an open-source browser SDK for the feedback widget, one-way outbound webhooks, and 40+ native integrations plus Zapier. Nothing supports server-side reads or bidirectional sync.

SCORECARD

ExistenceFAILNo public REST API; the browser SDK is client-side widget embedding, not a data surface.
AccessFAILThere is nothing to request: no developer portal, OAuth app registration, or key issuance exists.
CoveragePOORIssues flow outbound only via webhooks and native integrations; nothing lists or exports them in bulk.
AuthFAILNo API auth exists; the SDK uses a per-project destination ID and webhooks lack documented signing.
Docs & DXFAILOne official JavaScript browser SDK; no server-side SDKs and no API reference because there is no API.
StabilityMIXED
MCPGOODMarker.io ships an official remote MCP server hosted at connect.marker.io/mcp, available to all customers at no extra cost with OAuth or token auth. Setup guides live in the Marker.io help center and a companion skills repo under the vendor's GitHub org was updated in June 2026. help.marker.io ↗ VERIFIED 2026-08

Tried to integrate with Marker.io?
SOURCES
No public REST API at all, integrators cannot programmatically create projects, fetch/list issues, or build custom workflows beyond Webhooks and Zapier help.marker.io ↗
Webhooks are one-way only, external systems cannot push status/comment updates back into Marker.io via an API; bidirectional sync depends on Marker.io's hand-built native integrations feedback.marker.io ↗
No documented HMAC signing/verification on webhook payloads in public docs, receivers must trust the endpoint or implement IP allow-listing help.marker.io ↗
No bulk export endpoint, full-history extraction for migrations or analytics requires per-page UI export or webhook back-fill feedback.marker.io ↗
No OAuth app registration or developer portal, third-party ISVs cannot publish a one-click 'Connect Marker.io' install for their users marker.io ↗
Native integrations into Jira/Asana/ClickUp/Linear are first-party and not a public API, custom integrators building into less common destinations have to fall back on Zapier (with its own rate limits and latency) marker.io ↗
Browser SDK is client-side only and exposes no server-side hooks, any backend automation (e.g., post-process issues server-side before they reach Jira) must be implemented via Webhooks github.com ↗
Custom metadata passed via the Browser SDK is not queryable later via any API, useful for context in a single ticket but invisible to analytics tooling help.marker.io ↗
Zapier and Webhooks rate limits/latency are governed by those platforms, not Marker.io, debugging delivery failures is split across multiple vendors marker.io ↗
AI translation/rewrite/title-generation features (beta) call out to LLM providers from Marker.io's backend; there is no documented per-project opt-out or audit log of LLM calls feedback.marker.io ↗
No published SLA or rate-limit contract for Webhook delivery, failures and retries are not documented in public docs help.marker.io ↗
Browser SDK examples in GitHub README are minimal, community has filed issues asking for fuller framework integration guides (React, Vue, Angular, Next.js) github.com ↗
No public REST API, the single most-voted feature request on Marker.io's own public feedback portal; integrators cannot programmatically create projects, fetch issues, or sync custom systems feedback.marker.io ↗
Limited two-way sync, although Marker.io pushes tickets out to Jira/Linear/etc., status updates back from those systems can lag or miss fields; integrators have asked for true bidirectional API-driven sync help.marker.io ↗
No pinned/anchored comments on parts of a page (a feature BugHerd has), leads to duplicate feedback on the same UI element marker.io ↗
Pricing scales aggressively past Starter, entry tier $39/mo covers only a handful of seats; mid-market teams find themselves on Team/Company plans quickly marker.io ↗
Some users report a learning curve for non-technical client reviewers, the widget UI and login/guest flow can confuse first-time users g2.com ↗
Video feedback / longer screen recordings have been requested but are limited in scope/length compared to session replay g2.com ↗
Mobile/responsive bug capture is weaker than desktop; reporting from mobile breakpoints is fiddly getapp.com ↗
Browser-extension vs JS-snippet setup choice confuses first-time admins; documentation requires several clicks to disambiguate help.marker.io ↗
Reporter-vs-seat licensing model is unusual, internal collaborators pay, end-user reporters are free; misunderstood at procurement time marker.io ↗
SAML SSO and advanced security features are gated to higher tiers (Company/Enterprise) marker.io ↗
Some users report widget conflicts with host-site JavaScript frameworks (Vue/React shadow DOM, z-index, event-handler collisions) in edge cases help.marker.io ↗
Reporting/analytics dashboard is thin, limited cross-project dashboards, no native time-in-status, no SLA reporting capterra.com ↗
AI features (translation, rewrite, title-generation) are in beta and not configurable per-project; some teams want to disable LLM processing on regulated content feedback.marker.io ↗
