Act-On

Act-On Software is a cloud-based marketing automation platform used by B2B and B2C marketing teams for email marketing, lead generation and nurturing, landing pages and forms, website visitor tracking, lead scoring and segmentation, custom data, and campaign reporting. Act-On publishes four OpenAPI 3.1 documents through its developer portal covering 158 operations on one gateway host (https://api.actonsoftware.com, with an EU region at api-eu.actonsoftware.com): the legacy form-encoded /api/1 surface, the newer JSON Act-On Contacts layer at /ucl/v2, a transactional email endpoint at /ete/v1, and a separately versioned Custom Objects Service at /custom-objects/v1 that is in request-only beta. Authentication is OAuth 2.0 with password, refresh_token and authorization_code grants and no scopes. Act-On also ships a signed outgoing-webhook event surface with nineteen documented event types. Added to the API Evangelist network from a Norwest Venture Partners portfolio lead and enriched from Act-On's public developer surface.

Act-On publishes 25 API contracts indexed on the APIs.io network, including Account API, Campaigns API, Custom Data Dataset API, and 22 more. Tagged areas include Company, Marketing, Marketing Automation, Email Marketing, and Email.

The Act-On catalog on APIs.io includes 1 event-driven AsyncAPI specification, 1 JSON-LD context, and 1 Spectral governance ruleset.

Act-On’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, changelog, and 40 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 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):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too
Pagination +5 pts — share of collection GETs (an array, or one wrapped in data/items/results ...) that declare a page/limit/offset/cursor parameter, a Link header or a next/cursor field; na with no collection GETs

3 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Governance scores 22.0 — up to +9.4 composite points
Developer Ergonomics scores 66.1 — up to +6.8 composite points
Contract Quality scores 73.0 — up to +6.8 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.

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
Salesforce AppExchange (CRM, outbound, business-process automation)	builds-on	15.9	-	-
Zoom App Marketplace and Partner Ecosystem (builders and partners on Zoom)	builds-on	15.9	-	-
Pipedrive Marketplace (CRM integrations from third-party publishers for the SMB sales CRM)	builds-on	15.9	-	-

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 2

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.
