About Slack

Slack is a channel-based messaging platform. With Slack, people can work together more effectively, connect all their software tools and services, and find the information they need to do their best work - all within a secure, enterprise-grade environment.

What an agent can do in Slack

Every Slack action is classed by the platform as a read, a change or a send. Reads run at once. Changes and sends are held for a person by default.

How approvals work

Slack questions

Can an agent change data in Slack on its own?

Not by default. Changes and sends in Slack are held for a person's approval. The approval is recorded, and the action is sent once, never twice, with 10 seconds to undo.

What can an agent read in Slack?

This connector lists 70 read actions. Reads run at once, without waiting for approval.

How does Slack connect?

It connects with OAuth 2.0. Connectors are built and maintained by third-party developers; availability is confirmed during scoping.
