Add a client contact in Harvest from Slack

Carry a confirmed client introduction into Harvest while the right contact details are in the conversation.

Trigger

Channel Message Received

Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.

Action

Create Client Contact

Tool to create a new client contact. use when you need to add a contact under an existing client. call after you've retrieved or confirmed the client id.

Why this helps

Contact details can be scattered across messages, making it harder to keep client records current.

  • Keep confirmed contact details with the existing client record.
  • Reduce manual copying from Slack conversations.
  • Avoid attaching a contact to the wrong client when context is unclear.

Setup

Build it in a few focused steps.

  • 1Connect Slack and Harvest to Notis once in the portal.
  • 2Create an automation in the portal, or ask Notis in plain language to add a confirmed Slack contact to the specified existing Harvest client.
  • 3Tell Notis to create the contact only when the client and contact details are clear, and to report uncertainty about the client match.
  • 4Pick the Slack channel message trigger and choose a channel for run reports.
  • 5Test with one real contact introduction and verify the contact appears under the correct client.

Questions about this workflow

Does the client need to exist first?

Yes. The Harvest contact action requires an existing client, so the client should be confirmed first.

Will a name-only introduction be enough?

Have Notis report missing contact details rather than create a partial or incorrectly matched record.
