# Slack API

> Discover, navigate, and call Slack Web API methods (the family.method endpoints at slack.com/api like chat.postMessage, conversations.history, users.info, views.open). Use this skill whenever the developer asks which Slack API method does something, needs a method's required OAuth scopes or token type, wants to call or test a Web API method, is handling cursor pagination (nextcursor), hitting rate limits (tier/ratelimited/Retry-After), or debugging API errors like missingscope, invalidauth, or channelnotfound. Also trigger when they paste a slack.com/api/ URL or a docs.slack.dev/reference/methods link, or ask how to list/fetch/post/update Slack resources via the API. This skill covers the Web API method layer: finding the right method, reading its contract (scopes, arguments, errors), and calling it over raw HTTP with curl or through a Slack SDK.
