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 10 APIs on the APIs.io network, including Campaigns API, Do Not Contact Domains API, Events API, and 7 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 25 more developer resources.

  note: 'Round 2. Located PersistIQ''s own OpenAPI 3.0.1 document at https://api.persistiq.com/api-docs/v1/swagger.json —
    reachable from the Swagger UI on the API host root, and never linked from the published API reference. It adds four surfaces
    the derived spec did not have (tags, campaign create/duplicate, campaign replies, webhook plugin) and replaced the derived
    spec as the evidence base for authentication, conformance, errors, data-model and conventions. The WellKnown pointer was
    REMOVED: every /.well-known/ path 404s on both hosts, so the pointer asserted a surface PersistIQ does not serve.'
