What Slack gives you
Per-Company Configuration
Configure it independently for each brand on a multi-company install, so every company runs with its own settings.
Fully Translatable
Every staff and client label ships in editable language files, ready to translate into any language or reword to match your brand.
Long Notifications Delivered in Full
A notification too long for one message is split across consecutive messages instead of being cut short, so nothing is silently lost off the end.
Built-In Demo Mode
A built-in demo mode runs the whole extension from bundled sample data, so you can trial every screen and action before you have an account or API key.
Encrypted Credentials
Both the bot token and the Incoming Webhook URL are stored encrypted, so the credentials that can post into your workspace are never sitting in the database in plain text.
Full Request Logging
What it sends and what comes back is recorded in Blesta's own log, with credentials never written to it, so you can see exactly what happened without leaving your admin area.
Mention the Channel on Delivery
Choose whether each notification also pings @here for active members or @channel for everyone, so urgent alerts are impossible to scroll past. Leave it on None for quiet delivery.
One-Click Connection Test
A test button on the settings page checks your credentials against the live service and reports back exactly what it said, without saving half-typed settings or waiting for a real event to fire.
Custom Bot Name and Icon
Override the display name and set an emoji shortcode as the message icon, so Blesta notifications are instantly recognisable in a busy channel. Leave both blank to use your Slack app's own identity.
Separate Staff Channel
In bot token mode, set an optional staff channel and any notification addressed to a staff member is posted there instead, keeping internal alerts out of the channel your team watches for client activity.
Write-Only Credential Fields
Stored credentials are never rendered back into the settings page, and leaving a field blank when you edit keeps the saved value, so a secret is never exposed in day-to-day admin work and cannot be wiped by accident.
Connect With a Bot Token or an Incoming Webhook
Use a Slack app bot token to post into any channel you name, or paste an Incoming Webhook URL to get running without creating a bot at all. Fill in whichever suits your workspace and the messenger uses that mode for both live sends and connection tests.
Properly Formatted Slack Messages
Notifications arrive as a structured Slack message with a heading, the message body and a footer, not a dump of raw HTML. Bold, italics and links from the notification template are converted to Slack's own formatting, and Slack's reserved characters are escaped so nothing renders wrong.

-
Install the Messenger:
- Log in to your admin Blesta account and navigate to Settings > Messengers, then click the Available tab.

Configure the Messenger
-
Manage the Messenger:
- Navigate to Settings > Messengers (
/admin/settings/company/messengers/installed/). - Find the "Slack" Messenger and click on "Manage".
- Choose how the messenger connects to Slack, then click "Update Settings":
- Bot token mode: enter your API Token and the Channel ID to post to.
- Incoming webhook mode: enter an Incoming Webhook URL instead and leave the API Token blank. The webhook posts to the channel it was created for.
- Fill in either the API Token or the Incoming Webhook URL, not both. If you don't know how to find them, refer to the instructions below.
- Navigate to Settings > Messengers (
-
Check the Connection:
- Click "Test Connection" on the same page. It sends one test message using whichever mode you filled in and reports back what Slack said, without saving anything.

-
Messenger Configuration:
- Under "Messengers", click on "Messenger Configuration".

-
Enable Notifications:
- Under "Messengers", go to "Message Templates".
- Ensure the relevant templates are enabled.
Settings Reference
| Setting | Description |
|---|---|
| API Token | Bot token of your Slack app, starting with xoxb-. Used with the Channel ID. Leave blank if you are using an Incoming Webhook URL instead. |
| Channel ID | The channel notifications are posted to in bot token mode. |
| Staff Channel ID | Optional. Notifications addressed to a staff member are posted here instead of the main Channel ID, keeping internal alerts separate from client ones. Bot token mode only. |
| Incoming Webhook URL | Optional alternative to the API Token: a Slack Incoming Webhook URL (https://hooks.slack.com/services/...). The webhook posts to its own channel, so Channel ID and Staff Channel ID are ignored in this mode. |
| Bot Name | Optional display name for the messages. Leave blank to use your Slack app's own name. |
| Bot Icon Emoji | Optional emoji shortcode used as the message icon, for example :bell:. Leave blank to use your Slack app's own icon. |
| Mention on Delivery | Optionally ping the channel when a notification arrives: None, @here (active members) or @channel (everyone). A notification long enough to be split across several messages pings only once. |
| Enable Mock API | Simulates deliveries from built-in sample responses instead of contacting Slack, so you can trial the messenger before you have a token or webhook. Turn it off for live sends. |
The API Token and the Incoming Webhook URL are stored encrypted and are never shown back to you. Leave them blank when you save to keep what is already stored, and type a value only when you want to replace it. Entering one of them clears the other, since the two modes are mutually exclusive.
Finding Your API Token, Channel ID or Webhook URL
-
API Token:
- Follow the Slack guide to create a bot user.
- Add the "chat:write" scope.

Slack Messenger by Blesta.Club - Updating Guide
To keep your Slack Messenger up-to-date, follow the steps outlined below:
Updating Guide
-
Obtain the Updated Messenger:
- Download the latest version of the Slack Messenger from the download section of my.blesta.club.
-
Upload to Blesta:
- Upload the updated Slack Messenger to your Blesta messenger directory:
/var/www/html/blesta/components/messengers/slack/
- Upload the updated Slack Messenger to your Blesta messenger directory:
-
Update the Messenger:
- Log in to your Blesta admin account.
- Navigate to Settings > Messengers.
- Find the Slack Messenger and click the "Update" button.
-
Blesta version (updating to 3.0.0):
- From 3.0.0 the Slack Messenger is built for Blesta 6.0 and newer and no longer runs on Blesta 5. Upgrade Blesta first; if you must stay on Blesta 5, keep the last 2.x release.
- Nothing else changes on update: your saved settings carry over exactly as they are, and the Manage page only picks up the Blesta 6 admin styling.
-
Re-save your settings once (only if you are coming from 1.0.0):
- The API Token has been stored encrypted since 1.1.0. If your last version was 1.1.0 or newer there is nothing to do here. A token saved by 1.0.0 remains readable and keeps working, but it stays in plain text until the settings are saved again, so open Manage on the Slack Messenger and click "Update Settings" once to have it re-stored encrypted.
- From 2.0.0 the API Token and the new Incoming Webhook URL are both masked and are never shown back to you. Leave them blank when you save to keep what is already stored, and type a value only when you want to replace it.
-
New optional settings in 2.0.0 (no action required):
- 2.0.0 adds a Bot Name, Bot Icon Emoji, a Mention on Delivery option, a separate Staff Channel ID, and an Incoming Webhook URL mode. They all default to off/blank, so existing installs keep behaving exactly as before until you choose to fill them in on the Manage page. Notifications are now sent as richer Block Kit messages automatically.
No other changes are needed outside of updating the files. Any breaking changes will be communicated to clients by the Blesta.Club team prior to it being made available for download!
Keep your Slack Messenger up-to-date to ensure you have the latest features and improvements.

Slack Messenger by Blesta.Club - Usage Guide
Once your Slack Messenger is installed and updated, you'll want to configure it to suit your needs. Follow the steps below for a comprehensive setup.
Settings
All settings live on Settings > Messengers (/admin/settings/company/messengers/installed/),
under "Manage" on the Slack Messenger.
Choosing How to Connect
The messenger talks to Slack in one of two modes. Fill in one or the other, not both:
- Bot token: enter your API Token (it starts with
xoxb-) and the Channel ID to post to. This mode can route staff notifications to their own channel. - Incoming webhook: enter an Incoming Webhook URL and leave the API Token blank. The webhook posts to the channel it was created for, so Channel ID and Staff Channel ID are ignored. Only
https://hooks.slack.com/...addresses are accepted, because that is the only place Slack issues webhooks.
Both credentials are stored encrypted and are never shown back to you. Leave them blank when you save to keep what is already stored, and type a value only when you want to replace it. Entering one of them clears the other.
Optional Settings
- Staff Channel ID: in bot token mode, notifications addressed to a staff member post here instead of the main channel, so internal alerts stay out of the channel your team watches for client activity. Leave it blank to send everything to one channel.
- Bot Name and Bot Icon Emoji: override the name and icon the messages appear under, for example
:bell:. Leave them blank to use your Slack app's own identity. - Mention on Delivery: ping the channel when a notification arrives -
@herefor active members or@channelfor everyone. Leave it on "None" for quiet delivery. A notification long enough to be split across several messages pings only once. - Enable Mock API: runs the messenger from built-in sample responses instead of contacting Slack, so you can trial it before you have a token or webhook. Turn it off for live sends.
Testing Your Settings
Click Test Connection to send one test message using whichever mode you filled in. The result appears next to the button and shows exactly what Slack said, so a wrong channel or an expired token is obvious immediately. A test never saves anything - click "Update Settings" afterwards to keep what you typed. Because the credential fields are never shown back to you, re-enter your API Token or Webhook URL before running a test on an already-configured messenger.
Notification Formatting
Notifications are posted as Slack messages with a heading, the notification body and a footer. Bold, italics and links from your message templates are converted to Slack's own formatting, and a notification too long for one Slack message is split across several rather than being cut short. What was sent and what Slack answered is recorded in Blesta's messenger log under Tools > Logs.

v3.0.0 - 2026-09-15
PHP 8.2 - 8.4 · Blesta 6.x
Now built for Blesta 6: the messenger installs and runs on Blesta 6.0 and newer, and no longer supports Blesta 5
The settings page is rebuilt for the Blesta 6 admin theme: related settings now sit two per row so the page is shorter, and the "Test Connection" button and result messages match the new look in both light and dark mode
No settings change on update: everything you already saved carries over as it is
v2.0.0 - 2026-09-11
PHP 7.2 - 7.4, 8.1 - 8.4 · Blesta 5.x
Notifications are now sent as rich Block Kit messages (a titled header, the body, and a footer) instead of plain text
Added optional Bot Name and Bot Icon Emoji settings so notifications can be branded per company
Added an optional Mention on Delivery setting to ping @here or @channel when a notification arrives
Added an optional Staff Channel ID so staff notifications can be routed to a separate channel from client ones
Added Incoming Webhook URL mode as a simpler alternative to creating a bot and API token
Fixed the API Token being displayed in readable text on the settings page; it is now masked, and leaving it blank keeps the token you already saved
The Incoming Webhook URL is masked on the same terms as the API Token: it is never shown back to you, and leaving it blank when you save keeps the URL you already stored
Slack rate limits are now retried once, and a message Slack still refuses is named as rate limited in the messenger log rather than blending in with other delivery failures
Fixed connection problems all being recorded the same way; the messenger log now names the reason, such as a DNS failure, a TLS failure or a timeout
v1.0.0 - 2024-09-22
PHP 7.2 - 7.3, 8.1 - 8.4 · Blesta 5.x
