hello

Slack is a flexible instant messaging platform for organizations. It allows you to connect with your colleagues, share documents, and organize teams. It also allows teams to collaborate with images, videos, voice messages, and huddles across teams, time zones, and physical spaces. Slack’s API has allowed it to become a highly integrated productivity tool.

In this course, you’ll become efficient at automating chats, managing channels, and making interactive messages using the API. Learn how to share and manage files on Slack using the API. At the end of the course, you’ll use Slack’s Bolt for Python framework for building a small, custom application and integrating with Slack directly.

# Overview

There are instances where we may have to update a message already sent on the channel. For instance, we might want to update previous messages regarding the weather forecast with better, updated, and more accurate predictions. To update such messages, we'll use the `chat.update` endpoint. We could also run a script with `chat.scheduledMessages.list` to update some already scheduled messages we might have set.

Let’s look at the following endpoints in this lesson:
1. `chat.update`: This endpoint updates a message. 
2. `chat.scheduledMessages.list`: This endpoint returns a list of scheduled messages. 

# Update a message

To update a message, we'll access the `https://slack.com/api/chat.update` endpoint. To update a message, we specify a previously sent message using its timestamp. There are multiple ways to obtain a message's timestamp. However, for now, we'll use the timestamp which is sent back to us as a response to posting a message using the `chat.postMessage` endpoint.

Some important query parameters for the `chat.update` endpoint are the following:
