Salesloft API
Salesloft documents a REST API at developers.salesloft.com covering people, cadences, calls, and webhooks over OAuth 2.0. Production OAuth apps are partner-gated via partners@salesloft.com, and even a plain API token means emailing support. Team-wide limit: 600 cost units a minute.
Frequently asked questions
Salesloft scores D on the API Report Card. Salesloft documents a REST API at developers.salesloft.com covering people, cadences, calls, and webhooks over OAuth 2.0. Production OAuth apps are partner-gated via partners@salesloft.com, and even a plain API token means emailing support. Team-wide limit: 600 cost units a minute.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
Salesloft is a cloud-based revenue orchestration platform (originally a sales engagement / 'cadence' tool) that sits between a CRM (Salesforce, HubSpot, Dynamics) and the front-line revenue team.
Vertical: Sales engagement / revenue orchestration (horizontal SaaS, not industry-specific). SDRs and AEs work out of Salesloft all day: they import target accounts and contacts (often from Salesforce or a data provider like Cognism/ZoomInfo), enroll prospects into cadences that mix email steps, call tasks, LinkedIn touches, and manual research, and dial through call tasks via the integrated dialer.
Salesloft reports 4,000+ customers and holds 4.5/5 across 11,129 verified reviews on G2, making it one of the two most-reviewed sales engagement platforms on the site (alongside Outreach).
Yes, for any B2B revenue org that runs on Salesloft, the platform is the system of record for the entire prospecting + outreach + early-funnel dataset: the full people and account database, every cadence definition and enrollment, every outbound email send/open/reply with full thread content, every call attempt with recording and AI-generated transcript and summary, every meeting recording and coaching note, deal records and engagement scores, forecast submissions and roll-ups, and, via Drift, every website chat conversation, qualified lead, and intent signal.
Founded 2011 in Atlanta by Kyle Porter, Rob Forman, and Tim Dorr; pivoted from a sourcing tool to the modern cadence/sales engagement product around 2014.
Drift OAuth tokens were stolen and used against 700+ downstream tenants in Aug 2025; Salesloft revoked all active Drift OAuth + refresh tokens, forcing every integrator to re-auth. 600 cost-units/minute rate limit is team-wide, not per-integration, multiple internal tools compete for the same budget.

Common alternatives include Outreach, Apollo.io, HubSpot Sales Hub, Salesforce Sales Cloud / Agentforce Sales, Gong, Groove (Clari). Graded alternatives appear under "More from the report card" below.
Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
