Slack and Webex Integration – Connect Slack and Webex

Connect Slack Webex

Connecting Slack and Cisco Webex needs to be native, seamless, and simple to administer.

Standalone, both these apps have achieved this messaging nirvana.

To go one step further and connect these apps to work across platform, there are several ways to achieve this. Some better than others.

We often hear from customers trying to connect Slack and Cisco Webex to get the most out of each solution.

However, this often results in another chat app being introduced and limited or loss of functionality.

We’ve highlighted 4 ways to connect Slack and Webex then gone out and found a better one for internal and a better one for external.

1- Connect Slack and Cisco Webex via workflows


a. Workflow apps allow IT admins to quickly connect Cisco Webex and Slack. Generally, workflows only take a matter of minutes to set up. If you want to set up a one-off integration or trigger from one platform to the other, this is the ideal solution.

b. Most workflow engines come with intuitive interfaces so no back end coding is required to configure behavior between platforms.


a. Integrations need to be set up one by one and are time-consuming if you need to connect entire organizations.

b.When triggers and actions need to be modified, integrations must be modified one by one.

c. Workflow software is limited by number of integrations.

d. Workflow triggers sometimes only work one way. Communications in Slack could make it to Cisco Webex but not vice versa.

2- Configure webhooks for Slack & Cisco Webex


a. Webhooks are a simple and cost-effective method of joining Slack and Webex together for certain events. If the scenario resides in a single channel, webhooks provide a good solution to connecting Slack and Webex..

b. The Slack API enables you to “make it fancy” with advanced formatting. Interactive buttons and menus are available when using configuring webhooks in Slack.

a. Webhooks require lots of manual configuration. If you have multiple Slack channels or Webex spaces, this means configuring on a one-by-one basis.

b. Events triggered by webhooks in Cisco Webex are only near real-time. Whilst both Slack and Webex are persistent chat tools, the instant messaging experience is no longer instant in only “near real-time”.

News also broke in April 2020 when it was discovered some Slack webhooks has been exposed as potential phishing hooks.

Researchers said there are nearly 131,000 Slack webhook URLs available on the Internet.

3- Connect Slack and Cisco Webex using tubes


a. Tubes provide a two-way, real-time collaboration between Slack and Cisco Webex.


a. In 2017, Slack introduced Shared Channels which provides the functionality that tubes were set out to do. Essentially, this is providing a federation solution so that two different companies using Slack can communicate on the same platform.

b. The company behind these tubes was acquired in 2017 and has been off the radar since.

c. Like webhooks, tubes require lots of manual configuration. If you have multiple Slack channels or Webex spaces, this means configuring on a one-by-one basis. You probably need a full -team sync that will add any new channels created in the future automatically to the other side too, so you don’t have to keep setting up more tubes

d. Tubes are considerably more expensive than any of the other methods mentioned in this post i.e. webhooks, workflows and even the solution below.

4- How do I use Webex in Slack?

The Cisco team knows you use several apps every day. 

This is why Webex technology is adapting to work better with other tools. 

Cisco even produced a video on how teams can combine Slack and Webex:

How do I use Webex in Slack (internal):

If you’re an internal colleague, you can use the Cisco Webex Meetings and Slack integration. This app lets you schedule and join Cisco Webex Personal room meetings. You can also launch scheduled meetings within Slack. 

To start, you’ll need an admin to install the Webex Meetings integration for Slack. 

Search for Webex Meetings in the Slack app directory to install the app. 

After installation, clicking the call button in Slack will launch a Webex meeting. You can also see a list of upcoming Webex meetings in the Meetings list.

Internal users can use shortcuts in Slack like /WebexSchedule List today to see upcoming meetings.

Real-time notifications display when a meeting is about to begin. 

The Cisco Webex Meetings app doesn’t support users outside of your business.

How do I use Webex in Slack (external)

Using Webex in Slack with external team members is more complicated. 

One option is to set up a Slack shared channel

Shared channels let two companies or organizations work together in Slack. Shared channel members can use apps and integrations to start calls. 

If you and your external user have the Webex Meetings integration, you can use it for calls. This only works for Cisco Webex Meetings, not Webex. 

To set up your shared channel:

  • Click the + icon next to Channels
  • Create a channel
  • Add a name and description
  • Tick the box for Share Outside (name)
  • Enter the email address you want to send the invite to
  • Click Finished

Invitation links to shared channels expire in 7 days.

There’s no way to combine Webex with Slack using native integrations.

To message external contacts, you need a third-party solution. Mio syncs Slack and Webex.

With Mio, you stay in Slack, and your colleagues stay in Webex. Mio syncs the messages across both platforms. More on these below!

5 – The better solution for external comms?
Federation for Slack and Cisco Webex

Do you communicate with people outside your organization?

Do they use Slack when you use Webex?

Maybe it’s vice versa.

When this is the case, it becomes extremely unproductive moving out of your preferred app, into your external contact’s choice of app, and starting the conversation again.

Or even worse, end up resorting to email like it’s the 90s. (Okay, email has a purpose but you get the point).

That’s why Mio has created universal channels for Slack and Webex.

You can stay in Slack and send messages to your contractors, suppliers, or clients that use Webex (or vice versa).

Stay in Slack and chat with Microsoft Teams and Webex Teams users

They stay in their platform too and Mio translates the messages across platform.

And it’s not just messages that are supported! GIFs, emojis, channels, DMs, and message edits/deletes are all supported.

If this sounds like something you need, install Mio into your Slack workspace or Webex space.
