CloudTalk

CloudTalk is an AI-powered cloud call center and business phone system (CCaaS) for sales and customer support teams, backed by Point Nine. Its public REST API (served at https://my.cloudtalk.io/api, published as OpenAPI 3.0.1 version 1.7) lets developers automate calls, contacts, agents, groups, phone numbers, campaigns, tags, SMS, blacklists and notes, and read Conversation Intelligence data — transcription, sentiment, topics, talk-listen ratio and smart notes — plus initiate VoiceAgent calls. Authentication is HTTPS-only HTTP Basic Auth using an API Access Key ID and Secret; responses are JSON, paginated with a Collections Envelope, and rate limited to 60 requests per minute per company. Events are delivered through Workflow Automation triggers (native and virtual webhooks) rather than the REST API.

CloudTalk publishes 13 APIs on the APIs.io network, including Agents API, Bulks API, Calls API, and 10 more. Tagged areas include Company, Communications, Voice, VoIP, and Call Center.

The CloudTalk catalog on APIs.io includes 1 event-driven AsyncAPI specification.

CloudTalk’s developer surface includes documentation, API reference, support, engineering blog, pricing, signup flow, authentication, and 24 more developer resources.
