The Bot User OAuth Token (xoxb) and the app's Signing Secret. Message search and reminders also need a User OAuth Token (xoxp).

Invite the bot

Type /invite and the bot's name in each channel it should read or post in.

Watch the first run

64 actions in 10 groups. Allow all read operations once per app; approve each kind of write once.

Frequently asked

How do I connect Slack to Letaido? +

Create a Slack app from the manifest Letaido gives you, install it, and paste the bot token and signing secret into Letaido. Then invite the bot to your channels.

Which apps can it use together with Slack? +

The agent can use Slack with any of the 64 other apps it connects to. Checked jobs today include Google Analytics, Salesforce, Google Calendar, Gmail and Ahrefs.

Can I get alerts from other apps in Slack? +

Yes. Letaido can post a report or an alert to any channel the bot is in, on a schedule you set. If you ask, it only posts when something meets your rule.

Will it answer questions in a Slack thread? +

Yes. With the mention event on, someone mentions the bot with a question and Letaido replies in the thread, like the Google Analytics job above.

Does Slack message search work? +

Yes, once you add a User OAuth Token (xoxp). Slack doesn't let bots search messages and files or set reminders, so those need this second token.

What do I approve before it posts in Slack? +

Allow all read operations once per app; approve each kind of write once.

Is it built on the Slack API? +

Yes. It works through a Slack app you create in your own workspace, with 64 actions for messages, channels, canvases, files, reactions, users and reminders, plus 11 events that can start a job.

Is there a Slack MCP server? +

Yes. Slack's MCP server lets AI apps such as Claude and Perplexity search messages, read channels and threads, send messages and work with canvases. Only Marketplace or internal apps can use it, and admins approve each client. Letaido is not an MCP server: it has its own Slack connector, works with your other apps, and runs jobs on a schedule or on a Slack event.

Put an agent in your Slack channels

Connect Slack, then ask for a job like "Summarize the week's customer feedback in Slack every Friday". Leta gets it done on your schedule, or the moment you ask.
