17hats

17hats is an all-in-one CRM and business-management platform for service-based small businesses and solopreneurs, built around the idea that a one-person business wears seventeen hats. The platform combines lead capture, client pipelines, contact and project management, online scheduling, quotes, contracts and e-signature, questionnaires, invoicing and online payments, bookkeeping, email and SMS texting, and workflow automation into a single subscription product. 17hats states it serves more than 25,000 business owners across 100+ industries, including photographers, designers, coaches, planners and other service providers. 17hats does not publish a public developer program, API reference, or machine-readable specification; its only documented programmatic surface is an account-level API key issued from Account Settings > Integrations that authenticates its Zapier app, which exposes contact triggers and actions only.

17hats is profiled on the APIs.io network. Tagged areas include Company, CRM, Small Business, Invoicing, and Scheduling.

17hats’ developer surface includes authentication, documentation, support, getting-started guide, engineering blog, pricing, signup flow, 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 could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

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 github.com/api-evangelist/17hats: open an issue to ask a question, or submit a pull request to add artifacts.

  detail: 17hats' only programmatic surface is an account API key issued from Account Settings > Integrations that authenticates
    its Zapier connector (2 contact triggers, 4 contact actions) — there is no 17hats-hosted API reference, and api.17hats.com
    / developer.17hats.com only answer because *.17hats.com is a wildcard catch-all that returns the same app shell for a
    hostname that does not exist.
