At, a conversation intelligence (CI) platform for developers, we recently published the public workspace  on Postman for you to explore our APIs.’s APIs, the vast majority of which operate with the leading internet protocols for real-time communications (RTC) or real-time engagement (RTE)—such as PSTN, SIP, WebSockets, or RTMP—are designed to develop new experiences around conversations through connections, transformations, or visualizations. Now, with our brand-new public workspace, developers can easily test out our APIs and field more ideas in building new conversation-driven experiences with AI.

We created our public workspace to enable developers to try out our APIs for asynchronously uploading voice, video, or text messages for bulk offline processing. For instance,’s new Management API provides you with the ability to create fully customized sets of vocabularies for tracking all words semantically related to those vocabularies lists on conversations. In addition,’s Conversation APIs return analysis on conversation data for such things as topics, follow-ups, questions, action items, and more.’s public workspace Overview page in Postman

To check out these APIs, download the API collection for free or explore the public workspace online in Postman. You will find a total of 35 requests in the following areas:

  • Authentication
  • Async API: Ingest and process video, audio, and text files
  • Telephony API: Connect to VOIP and capture conversations in real time
  • Conversation APIs: Extract contextual insights, and conversation analytics
  • Management API: Create and track custom insights and intents

How to get started

Generating an authentication token and Postman: supporting API developers’s support for APIs is part of a broad initiative to help developers throughout their journeys. Our APIs are designed to facilitate the reduction of what is often described as the “Time to First API Call”—which is how long it takes a user to successfully make an API call with a response.’s public workspace on Postman is meant to help you make that first API call right out of the gate.

As Postman is the GitHub of the API world, another great advantage of’s public workspace is its ability to provide developers with new opportunities to create cross-API playgrounds. With Postman public workspaces, you can fork a workspace. After forking, you can add APIs to that workspace to create your own personalized workspace. Once you fork from’s public workspace, you can pull updates from our public workspace to stay synchronized with our latest APIs.

In addition to the new public workspace, we partnered with to release a collaborative workspace. In the Community public workspace, has assembled a collection for transcribing meetings with Check out Community public workspace.

Postman spotlights as a startup to watch

Postman actively encourages developers to share ideas and build more—now with the help of public workspaces. We are excited to join Postman in this effort, and we are proud that and our public workspace have been included in Postman’s Startups to Watch list spotlighting “promising, young startups who have the potential to disrupt their respective industries.”

Postman provides a wide range of functions and features to assist with API development, testing, and collaboration. Here are some commonly used functions in Postman:

  • Creating and Managing Requests: Postman allows you to create API requests by specifying the request method, URL, headers, parameters, and body. You can manage and organize requests within collections, including creating folders, adding descriptions, and reordering requests.

  • Request and Response Visualization: Postman provides a user-friendly interface to view and analyze request and response data. It supports syntax highlighting for various data formats such as JSON, XML, and HTML, making it easier to understand and validate the data.

  • Environment and Variables: Postman allows you to define variables and environments. Variables enable you to store and reuse dynamic values across requests, making them flexible and easy to maintain. Environments provide sets of variables specific to different environments (e.g., development, staging, production).

  • Tests and Assertions: Postman supports writing test scripts using JavaScript for automated API testing. You can write assertions to validate response status codes, headers, response bodies, and more. Postman's testing framework allows you to assert and validate different aspects of API responses.

  • Pre-request Scripts: Postman enables you to execute scripts before sending API requests using pre-request scripts. These scripts can be used to dynamically generate values, manipulate data, or set variables based on specific conditions.

  • Collection Runner: The Collection Runner allows you to execute a series of requests in a collection. It enables you to perform data-driven testing by iterating over multiple sets of data or environments. You can configure iterations, delays, and data sources for more comprehensive testing.

  • Mock Servers: Postman allows you to create mock servers for simulating API responses without a live backend. Mock servers are useful during development, allowing frontend developers to work independently by providing simulated API responses.

  • Documentation Generation: Postman can automatically generate documentation for your APIs based on your requests and collections. It provides a simple way to share API specifications and details with stakeholders.

  • Collaboration and Teamwork: Postman offers collaboration features such as sharing collections, collaborating on requests, and commenting on specific requests or collections. It also supports version control integration to manage changes and updates effectively.

  • Integration and Automation: Postman integrates with various tools and services, including version control systems (e.g., Git), CI/CD platforms (e.g., Jenkins), and API management solutions. It provides options for integrating with these tools to automate API testing and deployment processes.
