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, campaigns, activity events, and Do Not Contact domains, authenticated with a company-wide API key sent in the x-api-key header, with cursor pagination and a 100 request/minute per-key rate limit.

PersistIQ publishes 7 APIs on the APIs.io network, including Campaigns API, Do Not Contact Domains API, Events API, and 4 more. Tagged areas include Company, Sales Engagement, Sales, Outbound, and Email Outreach.

PersistIQ’s developer surface includes authentication, documentation, API reference, engineering blog, pricing, signup flow, and 19 more developer resources.
