Group calling
Kadoink can start group calls for up to 9 people from the homepage flow, and the API exposes call and grid endpoints for conference calls and grid-based calling.
Kadoink
Kadoink is a web, mobile, and desktop communication service for group calls, group texting, and contact-based messaging. It lets users ring people directly by phone and manage related contacts, groups, inbox items, and events through the site or API.
Overview
Kadoink is a social communication service that connects a web interface, mobile phones, and a desktop app around group calling, group texting, and contact-driven messaging. The homepage positions it around a simple prompt to “Say Who. Say Why.” and a call flow that can ring up to 9 people directly on their phones without requiring them to install an app or create an account.
The support pages and API docs show a broader system behind that flow: users can manage contacts and groups, post statuses, read inbox messages, handle calendar events, and run text commands through a versioned JSON REST API. The service is built around phone numbers, bearer-token authentication, and mobile verification, with SMS used for signup and alerts.
Features
Phone-first invitations
The site says invited people do not need apps or logins, because Kadoink rings their phones directly through SMS and voice workflows.
Group texting and commands
The product supports group text messages, contact-based texting, and text-command workflows from mobile or web according to the help pages and API docs.
Account and social workspace
The API docs include profile, contacts, groups, inbox, statuses, feed, calendar, and media endpoints, indicating support for messaging, contact management, status posting, and event management.
Audio and widgets
How-it-works and about pages mention recorded audio, audio sharing, and embeddable widgets as part of the product's communication model.
Use cases
Instant group calls
Use the homepage grid to gather a small group quickly and ring everyone at once, without asking participants to install software or create an account first.
Contact and group-based outreach
Add people as contacts and organize them into groups so you can trigger calls or texts by nickname or group name from the web or by SMS command.
Account and inbox management
Use the API or web dashboard to read inbox items, handle alerts, and manage verified sessions when building around Kadoink as a messaging layer.
Status and audio sharing workflows
Use statuses, feed endpoints, recordings, and media tools when you want a communication workflow that includes updates or shared audio rather than only live calls.
Coordination around events
Create and manage calendar events when the product is being used as part of a wider coordination flow across calls, messages, and scheduled activity.
