OptinMonster is a lead-generation and conversion-optimization SaaS from Awesome Motive that serves on-site campaigns — popups, floating bars, slide-ins, fullscreen fills, inline forms and gamified spin-to-win wheels — targeted by display rules such as Exit Intent, page-level targeting, geolocation, referrer and on-site behavior. Campaigns are built in a hosted visual builder at app.optinmonster.com and rendered on customer sites by a JavaScript embed served from the a.omappapi.com CDN. The platform exposes a private-key REST API at api.optinmonster.com (v1 and v2) and a mirror at api.omwpapi.com used by the first-party WordPress plugin, covering campaigns, leads, sites, integrations, revenue attribution and templates; a client-side JavaScript Events API of roughly sixty `om.*` lifecycle events for hooking campaign display, conversion and analytics; and an outbound webhook that POSTs captured lead data to a customer endpoint. Leads are routed to more than sixty marketing platforms through built-in integrations.
OptinMonster publishes 3 APIs on the APIs.io network. Tagged areas include Company, Lead Generation, Marketing, Conversion Optimization, and Email Marketing.
The OptinMonster catalog on APIs.io includes 1 event-driven AsyncAPI specification.
OptinMonster’s developer surface includes documentation, getting-started guide, support, engineering blog, pricing, signup flow, changelog, and 15 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Horizontal (data, software, accessibility, platform) 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/optinmonster: open an issue to ask a question, or submit a pull request to add artifacts.

Authenticated with an account API key supplied in the `X-OptinMonster-ApiKey` header (legacy `omapi-key` + user pairing
is still accepted). Responses are JSON; errors use a consistent `{error, code, message, status}` envelope with numeric
OptinMonster codes.

name: OptinMonster JavaScript Events API
description: A client-side event API exposed by the OptinMonster embed script (served from a.omappapi.com/app/js/api.min.js).
Roughly sixty documented `om.*` events fire across campaign initialization, display-rule evaluation, show/close, view
changes, form validation, conversion success/error, analytics impressions and conversions, and campaign actions. Handlers
are bound with `document.addEventListener` and receive the campaign object, letting integrators suppress campaigns, mutate
markup, or forward conversions to their own analytics.

x-coverage:
state: covered
reason: null
detail: A real, live REST API was found and mapped by probe (api.optinmonster.com v1/v2 plus the api.omwpapi.com mirror
named in the first-party WordPress plugin source), along with a provider-published llms.txt, a documented outbound webhook,
a dated plugin changelog and published pricing. OptinMonster publishes no OpenAPI and no public API reference, so the
contract here was recovered from live probes and first-party plugin code rather than from a spec.
