Voice and text, one feed.
Calls and SMS conversations run on the same Bland agents, so one set of triggers keeps Slack current on voice and text alike.
Bland + Slack
Bland posts call and SMS events to Slack, from summaries to transfers to tool failures, and agents can message a channel mid-call when a lead is ready.
What Bland does inside Slack.
Posts when something happens.
Triggers post to Slack on Bland events: a call ending with its summary, voicemail detected, a warm or cold transfer starting, an SMS received, a batch completing.
Messages built from the event.
Insert field drops values from the event payload into the message, like the caller's number, the summary, or the disposition.
Mid-call Slack tools.
A Slack tool lets the agent send a message or create a channel during the conversation, for example to flag a hot lead while the caller is still on.
Hears about problems first.
Tool failure and Knowledge gap detected events can post to Slack, so the team learns about a failing API or an unanswered question the same day.
Filters the noise.
Conditions on the event payload keep a channel to the calls that matter, such as transfers only, or calls with a given outcome.
How it deploys.
Connect your Slack workspace in Bland under Tools, then Connections.
Under Dispatch, then Triggers, pick the event and add conditions.
Choose the Slack message action, pick the workspace and channel, and insert event fields into the text.
Save (new triggers start Paused), test with Conditions only off, then set the trigger to Active.

Frequently asked questions.
How do I send AI call summaries to Slack?
Create a Bland trigger on the Post-call webhook event with a Slack message action. Pick the workspace and channel, then use Insert field to drop the summary, caller number, or any other payload value into the message.
Can the voice agent post to Slack during a call?
Yes. Build a Slack integration tool with the send message action and tag it in the agent's prompt. The agent posts when the moment in the tool's description happens, such as a caller asking to talk to sales.
Which Bland events can post to Slack?
All of Bland's own trigger events: post-call webhook, call started, inbound call received, voicemail detected, warm and cold transfer started, pathway node reached, SMS received, post-SMS webhook, batch completed, eval completed, knowledge gap detected, and tool success or failure.
Can Slack alert my team when calls go wrong?
Yes. Trigger on Tool failure to hear about a failing API, or set up Alerts on metrics like call length or API errors and deliver them through a custom tool that posts to Slack.
How do I test a Slack trigger before it goes live?
New triggers save as Paused, so nothing posts until you are ready. Test with Conditions only on to check your filters, turn it off to post a real test message, then switch the trigger to Active.
