Automation & workspaceUSSlack as the team's alert desk: leads, deals and calls from the CRM land in a channel, and the team acts on them without leaving the chat
Your team already lives in Slack, but the news about a new lead, a signed deal or a missed call still comes by email or gets noticed only when someone opens the CRM. Slack officially lets outside programs post messages, put buttons into them, listen to what people write and answer commands. We use that to bring the CRM into the channel where the team already works: the right message reaches the right people at once, and one click in the message updates the record.
Before the manager sees the request in the CRM only when he opens it, sometimes an hour later.
After a message with the lead's name and source lands in the sales channel within seconds, the first available manager presses «Take it», and the card gets an owner right away.
Before the missed call sits in the phone system log and is found the next day.
After the responsible manager gets a direct message in Slack with the client's name and the deal, presses «Call back», and the CRM records the task and the outcome.
Before the head of sales collects yesterday's picture by hand from several CRM reports.
After at the chosen time the channel receives one digest — new leads, deals that moved forward, deals that have not moved for several days, overdue tasks — and the meeting starts from it.
Before the team hears about it at the weekly meeting, and finance learns about the invoice from an email.
After the moment the stage changes to «Won», the general channel gets a message with the deal and the manager, and the finance channel gets its own notification to issue the invoice.
Before on the road the manager opens the CRM app, searches for the company, scrolls the history.
After he types a command with the client's name in Slack, and the bot replies in the same thread with the stage, the last contact and the next step.

Slack's Web API is the official interface for reading information from a workspace and making changes in it, such as posting messages.
Source: docs.slack.dev ↗ checked 2026-09-27Incoming webhooks are the simplest way to post messages from an outside app into Slack: a unique URL receives the message text as JSON.
Source: docs.slack.dev ↗ checked 2026-09-27The Events API lets an app react to what happens in Slack: Slack itself calls the app's server when an event occurs, so there is no polling.
Source: docs.slack.dev ↗ checked 2026-09-27Block Kit lets a message carry interactive elements such as buttons and menus; a message can hold up to 50 blocks.
Source: docs.slack.dev ↗ checked 2026-09-27An app may post about one message per second per channel, whichever way it sends them; short bursts above that are allowed.
Source: docs.slack.dev ↗ checked 2026-09-27Slack signs every request it sends to an app with a secret unique to that app, so the app can verify the request is authentic.
Source: docs.slack.dev ↗ checked 2026-09-27Slack allows an app about one message per second per channel; above that it answers with an error and a pause to wait, so we queue and group messages instead of posting each one. Slack must get a reply within three seconds both for events and for button clicks, so slow CRM operations run in the background and the user sees the result a moment later. Event delivery is best-effort: it may lag during Slack incidents, and events older than two hours are dropped, so key records are re-checked directly in the CRM. A simple posting address always writes to one fixed channel and cannot edit or delete a message; editing and posting to several channels need a full app. Scheduled messages can be set at most 120 days ahead and no more than 30 per five minutes per channel. Commands cannot be typed inside threads. Slack's no-code Workflow Builder is listed as available on paid plans only; the custom app we build does not depend on it.
Three steps from a first message to work on your project.
Describe the task in the form — in text or by voice. Budget and timing are optional.
A developer studies the brief, asks about anything unclear and sends an estimate.
Once scope and price are agreed, the work begins.
