PersistIQ

PersistIQ is a sales engagement platform for small teams to find new customers, start conversations, and personalize sales outreach at scale from one place. It combines prospect research (Chrome extension), multi-channel outreach (email, calls, tasks), campaign management with A/B testing, performance analytics, and CRM integrations. PersistIQ exposes a REST API (v1) for users, leads (prospects), lead statuses and fields, tags, campaigns (including duplication and inbox replies), activity events, Do Not Contact domains, and a webhook plugin carrying five events. It is specified by PersistIQ's own OpenAPI 3.0.1 document, served from the API host at /api-docs/v1/swagger.json. Authentication is a single company-wide API key sent in the x-api-key header, with page-number pagination and a documented 100 request/minute per-key rate limit.

PersistIQ publishes 12 APIs on the APIs.io network, including Campaigns API, Do Not Contact Domains API, Events API, and 9 more. Tagged areas include Company, Sales Engagement, Sales, Outbound, and Email Outreach.

The PersistIQ catalog on APIs.io includes 1 event-driven AsyncAPI specification.

PersistIQ’s developer surface includes changelog, authentication, documentation, API reference, getting-started guide, support, engineering blog, and 26 more developer resources.

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.

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/persistiq: open an issue to ask a question, or submit a pull request to add artifacts.
