SlackKit is a newly launched suite of embeddable UIs and APIs designed to simplify the integration of products with Slack, enhancing user engagement by delivering notifications directly within the workspace environment. This suite, developed by Knock, manages OAuth connections and tokens, provides customizable UI components for channel selection, and offers a robust set of Slack-specific APIs to facilitate seamless integration. It addresses the complexities of building Slack integrations by offering ready-to-use components like <SlackAuthButton /> and <SlackChannelCombobox />, which streamline the process of OAuth management and channel selection. With a focus on accessibility, internationalization, and customization, SlackKit allows developers to effortlessly adopt Slack notifications into their applications, improving visibility and responsiveness while freeing up time for further product development. The suite is available to all Knock customers, with the option to start with a free account offering a monthly allowance of 10,000 notifications.
