How to Get Started with Slack on Zapier#

The first thing you'll need to do to get started with hooking up Slack with Zapier and the hundreds of apps we work with is adding your Slack account to Zapier. When the time is right, we'll ask you to add your Account:

Get started with adding your account!

You should then get a pop-up window from Slack asking you which Slack Team account you'd like to connect:


You'll then be asked to authorize the connection between Slack and Zapier.


After authorizing, you'll get sent back to Zapier where you now have your Slack account connected!

Message Text Formatting#

To format your message's text with styling (such as bold, italic, block quotes, code blocks and lists) you'll simply need to enter these in the same way you would do on Slack.

For example entering this:

You can read more on formatting the text on messages on Slack's formatting help guide here.

Formatting Links#

Slack will recognise normal links and make sure they're clickable on your post.

If you want to make text into link, simply enter your link in the following format into the text field:

<http://www.zapier.com|Text to make into a link>

Like this:

link in Zapier

Which will look like this in Slack:

Slack Announcements.#

For special announcements such as @channel, @group, @here and @everyone, you'll need to enter those in the following format:

<!channel>, <!group>, <!here> and <!everyone>

Like this:

If you want to pass on an Emoji as part of your message, you'll just need to use the colon version of it for example:

Like this:

Common Problems with Slack#


Right now sending attachments within Slack messages through Zapier are not supported.

My triggers aren't picking up the messages I need!#

The message you're looking to trigger off of might be sent as a message attachment in Slack. If the message is proceeded by an indent, then it's a message attachment:

Slack Message Attachment Example

Normally these are messages sent by bots, slash commands, or other Slack integrations. Unfortunately, none of our triggers are currently able to trigger on content in message attachments.

Sending direct messages as a user#

This only applies to the legacy app (named Slack (Legacy). If you're creating a new zap, you can safely ignore this

Right now it is not possible to send direct messages to one user, from another user. Direct Messages will always be sent to the recipient via their Slackbot direct message.

Sending channel messages as a user#

There are no special actions needed to send messages as yourself. If you're seeing errors, please write in at contact@zapier.com.

Slash commands are not executing#

Unfortunately, it's not possible to post slash commands to Slack via their API, so if you send /giphy cute cats it'll just show up with that text.

If you'd like to use Zapier to build a slash command, check out this helpful guide.

Error: Could Not Add Service#

If you see this error, it means that your team's free Slack account is at the limit of 10 integrations. You'll need to upgrade your Slack account or disconnect another integration.

Channel names are posting as text rather than link#

If you see this:

But want this:

Make sure that the "Send @mentions notifications?" field is set to "Yes."

My New Mention trigger is not finding any messages#

You must specify either a User Name or a Highlight Word for this zap to work. If you specify both, then both the user name and the highlight word will need to be included in a single message in order to trigger the zap.

If you've specified one or both and the trigger, click the Continue button, then click "Connect & Continue". Once you see the spinning wheel, go into Slack and post a message with the trigger criteria in any public channel. Zapier will receive that message and you'll see the trigger marked as Test Successful:

When testing a "new message" trigger, the test says it can't find any messages even though there are plenty!#

When testing message triggers, we only look for messages from humans (not apps or bots). Human users have profile information that you might want to map (while bot users don't), so we want that to be available in the editor. If Listen for Bots is true, then we'll trigger properly during actual runs.
