Workspace messaging API for sending messages, reading channel history, and managing channels. Use when a workflow needs to post results, notify a team, or pull conversation context from Slack. Requires a bot token with appropriate scopes — most actions need the channel ID, not the channel name. 4 example endpoints available through Lava’s AI Gateway. See the Slack API docs for full documentation.
This provider requires your own credentials — connect your API key or OAuth account before use.
This is a catch-all provider — any valid URL under https://slack.com is supported. 200+ Slack Web API methods. Construct URL as https://slack.com/api/{method_name}. See https://api.slack.com/methods for full reference. The endpoints below are curated examples.
