SCORECARD

ExistenceFAILNo REST API, documented endpoints, or developer portal; the surface is one outbound webhook and a Zapier trigger for comments.
AccessFAILOnly the account owner's personal token exists; no partner program, developer signup, or app registration is available.
CoverageFAILOnly surface is an outbound comment export webhook and a Zapier trigger; no canvas CRUD, comment retrieval, or user endpoints.
AuthFAILWebhook POSTs carry no HMAC signing, and the single personal API token forces rewiring every Zap on rotation.
Docs & DXFAILDocumentation is two help-center articles; no API reference, event taxonomy, retry semantics, SDKs, or OpenAPI spec.

Supergood: Pastel isn't going to ship an API, so we did: stable endpoints, normalized JSON, managed auth.

SOURCES
No public REST API reference, usepastel.com has no /docs, /developers, or /api documentation site; apitracker.io's profile is largely empty apitracker.io ↗
Webhook documentation does not specify any authentication or HMAC signing mechanism, receivers can't cryptographically verify Pastel-origin POSTs help.usepastel.com ↗
Webhook delivery is only documented for the comment-export event; no published event taxonomy for canvas-created, canvas-approved, user-added, etc. help.usepastel.com ↗
No documented retry/backoff or `Retry-After` semantics on webhook failures, integrators must guess delivery behavior help.usepastel.com ↗
No OAuth app flow or scoped developer tokens, Zapier auth uses a single personal API token from the profile page, so rotation requires updating every connected Zap by hand help.usepastel.com ↗
Native integration set is one platform deep (Asana), every other PM/messaging destination requires Zapier or a custom webhook receiver asana.com ↗
No SDKs in Node/Python/Ruby/Go/.NET; no community libraries on GitHub for Pastel's surface; integrators write raw HTTP handlers from scratch apitracker.io ↗
No OpenAPI/Swagger spec published, API clients can't be code-generated, and there is no canonical schema for the webhook payload apitracker.io ↗
Zapier's per-task billing creates hidden marginal cost, high-volume comment streams (busy agency portals) burn Zapier Task quota and force expensive Zapier tier upgrades help.usepastel.com ↗
No developer portal or app-marketplace registration model, third parties cannot publish a one-click 'connect Pastel' OAuth app usepastel.com ↗
Webhook payloads include sensitive screenshot URLs and user metadata of in-progress client sites; no documented PII redaction or DLP controls before egress help.usepastel.com ↗
Comment-export is the only documented outbound data path, there's no documented way to programmatically read canvas state, approval history, or audit trail back out for migration/archive help.usepastel.com ↗
Free plan is restricted to 1 active canvas at a time; agencies juggling multiple client projects hit the wall immediately feedbucket.app ↗
72-hour commenting window on the free plan forces upgrade for any real client cycle medium.com ↗
Per-user pricing scales aggressively, $29/user/mo on top of base plan; agencies with 5–10 reviewers see bills jump quickly huddlekit.com ↗
Solo plan ($29/mo) capped at 3 premium canvases; jump to Studio ($99/mo) is steep with little middle tier commentblocks.com ↗
Lacks deep technical features (no built-in Kanban, no time-in-status, no SLA reporting); teams outgrow it as projects mature feedbucket.app ↗
Limited dashboard and reporting, hard to get cross-canvas visibility for agencies running 20+ active client projects commentblocks.com ↗
Comment list becomes unwieldy past 30–40 comments per canvas; preview text is insufficient to distinguish them, forcing repeated open/close g2.com ↗
Performance can be slow, canvas loading and comment-list scrolling lag on heavy projects g2.com ↗
Proxy-based snapshot approach struggles with auth-gated staging environments, SPAs with aggressive client routing, and sites that block iframe-style embedding bugherd.com ↗
Mobile/responsive feedback is functional but weaker than desktop; some breakpoints render inconsistently inside the canvas snapfeed.app ↗
No built-in task management / Kanban board, feedback has to be exported to Asana/Trello/ClickUp to be actionable bugherd.com ↗
Native integration set is thin, only Asana is first-party; other PM tools require Zapier glue help.usepastel.com ↗
No enterprise-grade plan tier or custom pricing publicly advertised; large agencies are forced into seat sprawl capterra.com ↗
Audit trail and approval-history features are usable but lighter than Filestage/Ziflow for regulated creative workflows huddlekit.com ↗
