HubSpot has an official Slack integration, and for notifications on a deal or a ticket it is usually the right first step: install it and see. The companies that come to us have usually found its edges. They want alerts routed by territory, product line or deal size to different channels, an approval that has to be recorded in HubSpot, an escalation that changes owner after an hour of silence, or a ticket thread that stays attached to the record. Those are rules, and rules are what we build.

The failure we see most is not a missing notification. It is a notification that goes to a channel of two hundred people, gets a thumbs-up emoji from one of them, and then nobody owns it.

What ECOSIRE builds

A custom integration between HubSpot and Slack built on a HubSpot private app (CRM API and webhook subscriptions or workflow actions, depending on your subscription tier) and a Slack app using the Web API and Block Kit. Scope comes from your pipelines and your teams.

Routed alerts with an owner

Events you choose (a deal entering a stage, a deal above a size, a ticket past its SLA, a high-intent form submission, a renewal date approaching) post to the channel or person your routing table names, by territory, product line, segment or amount. Each message carries the fields the reader needs and a link to the HubSpot record, and names a single owner. Where nobody acts within a window you set, the message escalates to a named backup instead of waiting.

Actions that write back to HubSpot

Buttons on the message let the right person claim a lead, change a deal stage, assign a ticket, log a note or approve a discount. A press goes to an endpoint that verifies Slack's request signature, maps the Slack user to a HubSpot user, checks that they are allowed to make that change, applies it through the HubSpot API and updates the message to show who did what.

Approvals with a record

Discount, quote or contract-term approvals are requested in Slack and recorded on the HubSpot deal: approver, decision, time and comment. The deal cannot advance past the approval stage until the decision exists.

Conversations stay with the record

For the cases that need it, a thread in Slack is linked to the deal or ticket, and chosen replies are logged as notes on the record, so the discussion is not lost when the channel scrolls.

Quiet by design

The build includes de-duplication, quiet hours, digest mode for lower-priority events, and queuing for bursts, because Slack rate-limits message posting per channel. A message log with status and retry makes a revoked token or a changed scope visible to an administrator.

Who this is for

Sales, success and support teams that live in Slack and run on HubSpot, and whose alerting rules are specific enough that a standard notification does not fit: routing by territory or product, escalation, and approvals that must be recorded. If the standard integration fits, use it.

How delivery works

1. Scoping call. We review your pipelines, properties, teams, Slack workspace structure and what the standard integration did not do for you. 2. Written quote. Scope, exclusions and the delivery date go to you in writing; building starts after you accept. 3. Build against test accounts. We build against a HubSpot test or developer account and non-production Slack channels. 4. Acceptance. You run your own scenarios, including approvals and escalations, and sign off. 5. Go-live and support window. We install the Slack app, switch on production and stay through your first busy period.

What this is not

It is not a replacement for HubSpot's own Slack integration where that already fits your needs, and it is not an off-the-shelf download. It is written for your HubSpot account and your Slack workspace after a scoping call, against a quote that fixes scope, exclusions and the delivery date, and it leaves your sales process and Slack administration in your hands.
