Blocks allow BOTS to augment the capacities of a chat message. At the moment only one block is available: `actions`, accepting only one type of element: `button`. <img width="708" alt="Screenshot 2024-11-15 at 19 14 02" src="https://github.com/user-attachments/assets/63f32a29-05b1-4f32-9edd-8d8e1007d705"> # Usage ```ruby Chat::CreateMessage.call( params: { message: "Welcome!", chat_channel_id: 2, blocks: [ { type: "actions", elements: [ { value: "foo", type: "button", text: { text: "How can I install themes?", type: "plain_text" } } ] } ] }, guardian: Discourse.system_user.guardian ) ``` # Documentation ## Blocks ### Actions Holds interactive elements: button. #### Fields | Field | Type | Description | Required? | |--------|--------|--------|--------| | type | string | For an actions block, type is always `actions` | Yes | | elements | array | An array of interactive elements, maximum 10 elements | Yes | | block_id | string | An unique identifier for the block, will be generated if not specified.

Discourse is the online home for your community. We offer a 100% open source community platform to those who want complete control over how and where their site is run.
Our platform has been battle-tested for over a decade and continues to evolve to meet users’ needs for a powerful community platform. Discourse allows you to create discussion topics and connect using real-time chat, as well as access an ever-growing number of official and community themes. In addition, we offer a wide variety of plugins for features ranging from chatbots powered by Discourse AI to functionalities like SQL analysis using the Data Explorer plugin.
