HoneyBook

HoneyBook is an all-in-one clientflow management platform for independent, service-based businesses - photographers, event planners, designers, consultants, coaches, and similar creative entrepreneurs. It combines CRM/lead capture, proposals, contracts and e-signature, invoicing and payments, scheduling, automations, and client communication in one product. HoneyBook does not publish a self-serve public developer API or a developer portal; third-party connectivity is offered through a limited set of native integrations (QuickBooks Online, Zoom, Calendly, Flodesk, Canva, Meta Leads, Slack, Asana, monday.com) and, most broadly, through Zapier. An internal API host (api.honeybook.com) is live and clearly powers the Zapier integration and native connectors, but HoneyBook has never published a self-serve technical reference, OAuth client registration flow, or endpoint documentation for outside developers, and community requests for direct API access date back to at least January 2024 with no roadmap commitment as of this review.

HoneyBook publishes 4 API contracts indexed on the APIs.io network, including Projects API, Contacts API, Pipeline API, and 1 more. Tagged areas include CRM, Clientflow, Proposals, Contracts, and Invoicing.

The HoneyBook catalog on APIs.io includes 1 Spectral governance ruleset.

HoneyBook’s developer surface includes authentication, documentation, engineering blog, and 10 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too
Agent Skills +5 pts — skills artifact present, graded by who authored it

Contract Quality scores 34.2 — up to +16.5 composite points
Developer Ergonomics scores 23.8 — up to +15.2 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from the provider profile at artifacts.apis.io/honeybook/apis.yml: open an issue on github.com/api-evangelist/honeybook to ask a question or point us at an artifact you publish.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Zoom App Marketplace and Partner Ecosystem (builders and partners on Zoom)	builds-on	19.4	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 5

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
