Messaging Integrations: Slack, Discord, Twilio, and Telegram
Krom Automation Pro connects to four messaging platforms: Slack for team communication, Discord for community channels, Twilio for SMS and voice calls, and Telegram for bot-based notifications.
Each integration is configured independently with its own credentials in Krom Automation settings, and each platform’s actions are available across all workflows once connected.
This page covers all four integrations in one place since each is focused on notification delivery rather than complex data syncing.
Slack #
Slack is a team messaging and collaboration platform. Krom Automation’s Slack integration gives you one trigger and four actions covering channel messages, direct messages, rich block messages, and channel topic updates.
Configuration
Required credentials:
- Bot Token — An OAuth bot token from your Slack app. It starts with
xoxb-. - Signing Secret — Required only for the Slash Command trigger. Found in your Slack app’s Basic Information page.
Setting up a Slack app:
- Go to api.slack.com/apps and click Create New App.
- Choose From scratch, give it a name like
Krom Automation, and select your Slack workspace. - Go to OAuth and Permissions and add the following bot token scopes:
chat:write,chat:write.public,im:write,channels:manage. - Click Install to Workspace and authorise the app.
- Copy the Bot User OAuth Token (starts with
xoxb-). - In your WordPress admin, go to Krom Automation > Settings > Slack and paste the bot token.
- If you want to use the Slash Command trigger, also copy the Signing Secret from the app’s Basic Information page and paste it into the Signing Secret field.
- Click Save.

Troubleshooting #
Slack messages aren’t sending. Check the execution log for the error. The most common cause is incorrect bot token scopes. Confirm chat:write and chat:write.public are added in your Slack app’s OAuth and Permissions settings. Also confirm the bot has been added to the channel you’re sending to — a bot cannot send to a channel it isn’t a member of.
Discord messages aren’t sending. Confirm the webhook URL is copied correctly and hasn’t been deleted in Discord. Webhook URLs are unique per channel. If you deleted and recreated the webhook, update the URL in your Krom Automation action configuration.
Twilio SMS isn’t arriving. Check that the recipient phone number is in E.164 format (+ followed by the country code and number). Also confirm your Twilio account has credit balance and that the from number is verified and active in your Twilio account.
Telegram messages aren’t sending. Confirm your bot has been added to the group or channel you’re sending to and has permission to post messages. Group chat IDs are negative numbers (e.g. -100123456789) — confirm you’re using the correct format.
