Notification Service: Creating a Slack Workspace

Create a Slack Workspace

To create a Slack workspace, follow these steps:

Visit https://slack.com/get-started#/createnew{:target="_blank"}.
Enter your email address and click Continue, or continue with Apple or Google.
Check your email for a confirmation code.
Enter the code on the Slack website.
Click "Create a Workspace" and follow the prompts.
For detailed instructions how to create a workspace via the Desktop App, on Android or iOS, refer to Create a Slack workspace{:target="_blank"}.

After creating your Slack workspace, you can add channels by following these steps:

Click the '+' icon next to 'Channels' on the sidebar of your Slack workspace.
Choose "Create a channel" and specify the channel name and purpose.
For enterprise grid organizations, refer to Slack's help article{:target="_blank"} for instructions.

To set up a webhook for sending notifications to your Slack workspace:

Create a Slack app{:target="_blank"}, following the instructions by signing in, adding name and workspace to put the app in.
After this, you'll be redirected to the setting pages of your new app. Choose Incoming Webhook and toggle Activate Webhook.
Scroll down to click the option Add New Webhook to Workspace.
The page will give you a link associated with the app you created. This link will be where API requests are sent to send messages to your Slack workspace.
To test if the webhook works as needed, you can try sending an API request to this link to see if the message goes through. I used Postman to test this. Remember that this is an application/json file.
Afterwards, the text channel should have a new message
Go to Slack's webhook documentation{:target="_blank"} to learn more about setting up webhooks.
