# Your first service
> Connect Synthetiq to an external system from a chat message — describe the service you need, review the plan, and configure the connection.
Connect Synthetiq to an external system from a chat message. In this tutorial, you describe a Snowflake data warehouse connection to Synthetiq, review the plan, and view the finished service.
## Prerequisites
* Synthetiq installed, signed in, and your Claude API key saved (see [Set Up Synthetiq and Set Your API Key](/quickstart/setup-and-api-key))
* Access credentials for the external system you want to connect (for this tutorial, a Snowflake account identifier, username, and password)
## Steps
Click the **chat icon** in the left menu, or press **⌘]**, to open the chat panel.
Type a description of your service into the chat. Include the system you want to connect to and what you need it to do.
For this tutorial, type:
> Create a service that connects to my Snowflake data warehouse so I can list databases, browse tables, and run queries
Press **Enter** to send your message.
The Workspace agent recognizes that you want to build a service and hands off to the **ServiceWriter** agent. A mode-switch indicator appears in the chat showing the transition.
The ServiceWriter agent presents a plan for your service. The plan card covers the service's tools, authentication method, and connection settings. Read through it to make sure it matches what you had in mind.
If the plan looks good, click **Accept & Proceed** at the bottom of the plan card. The ServiceWriter agent begins building your service.
If something needs changing, click **Request Revisions** instead and describe what you want adjusted.
The ServiceWriter agent creates your service's connection logic, tools, and authentication setup. You can watch progress as tool calls appear in the chat. This usually takes a minute or two.
When the build finishes, open the **Services** panel by clicking the **cable icon** in the left menu. Find your new service and click it, then go to the **Connection** tab to enter your Snowflake credentials — account identifier, username, and password.
Click the **Tools** tab to see everything your service can do. Each tool represents an action — like listing databases, browsing tables, or running queries.
You can ask the agent to make changes after the service is built. For example, "Add a tool to my Snowflake service that checks query history" — the agent will update the service without starting from scratch.
