Frequently asked questions
Dialpad scores A on the API Report Card. Dialpad runs a self-serve developer portal at developers.dialpad.com with REST APIs for calls, SMS, contacts, stats, and routing, plus OAuth 2.0 and WebSocket event subscriptions. AI Virtual Agent and Digital Engagement APIs are gated to Pro and Enterprise contracts.
Dialpad has a workable official integration path. Most engineering teams can build against it directly. Open API: self-serve, documented, with SDKs
Dialpad is the AI-first cloud business-communications platform founded in 2011 by Craig Walker, the same operator who built Grand Central (acquired by Google and rebuilt as Google Voice) and the original 'Dialpad Communications' consumer VoIP service sold to Yahoo in 2005.
Vertical: AI Cloud PBX / Business Communications, horizontal UCaaS + CCaaS infrastructure, not industry-specific. Admins provision DIDs and toll-free numbers, port numbers from legacy carriers, configure auto-attendants and IVR call flows, build call routing groups, assign extensions and departments, set up offices/sites, manage e911 locations, and grant role-based admin permissions.
Dialpad discloses ~50,000 business customers (including 65%+ of the Fortune 500), >$100M committed ARR, ~700+ employees (some sources cite 1,000–5,000), a ~$2.2B private valuation reached in 2021–2022, and operations across 19+ locations in six countries.
Yes, severely, Dialpad is the system of record for a customer's entire business communications stream: every inbound and outbound call with timestamps, duration, ANI/DNIS, dispositions, and routing decisions; full call recordings (audio); Dialpad Ai-generated transcripts, summaries, action items, and sentiment scores on every recorded call; SMS/MMS message history; voicemail audio and AI transcriptions; Dialpad Meetings video recordings, transcripts, in-meeting chat, and Ai Recap summaries; fax history; contact-center queue state, agent disposition codes, IVR routing trees, CSAT/NPS survey responses, QA scorecards, Real-Time Assist coaching events, and DID/toll-free inventory; omnichannel customer-interaction history across voice/SMS/webchat/email/social; Dialpad Sell deal-risk signals, call summaries, and CRM-sync logs; and skills-based routing rules + WFM forecasting/scheduling data.
~14 years old, founded 2011 by Craig Walker in San Francisco / San Ramon, CA as the spiritual successor to his prior Dialpad Communications (acquired by Yahoo in 2005) and Grand Central (acquired by Google in 2007 and rebuilt as Google Voice).
Reporting and data-export ergonomics are weak, Capterra/G2 reviewers report 'awful' export formatting, no ability to choose which fields appear in reports or what order, and entire KPIs disappearing when multiple contact centers are combined, forcing repetitive exports and manual merging. Stats APIs are siloed by product line (Connect vs Support vs Sell) and by contact-center grouping; customers consolidating cross-product analytics must stitch responses client-side because no single 'unified call log' endpoint exists.

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.
