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.
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.
