Many teams building with agents use LangGraph for agent orchestration, together with LangSmith for agent observability.

If you’re one of them, getting started with Synth is now just a few clicks away.

​
Quick Start Guide

​
1. Add Your Langsmith API Keys

Log in, then navigate to your initial in the top right. Click settings, and first go to the ‘Credentials’ tab. There, add your Langsmith API key. NOTE - Langsmith currently only supports Synth integration for users with Pro and Enterprise plans. We will update as that changes!

​
2. Connect Your LangGraph Project

Now, head to the ‘Systems’ tab in the settings page. Click ‘New System’ and select ‘LangSmith’ as the integration type.

Enter in your LangSmith credentials - there are helpful images to guide you in retrieving the credentials from your Langsmith web interface. Langsmith organizes information into Workspaces, under which you can have multiple projects. IDs for both workspaces and projects are easy to copy to clipboard when you click into the respective pages.

​
2. Configure Your Agent Flows

Unless you’ve spoken with our team, we recommend you keep the default cron schedule settings! Next, go to the Agents page to confirm that the configuration succeeded. Go to the system name selector and choose the name corresponding to the Langsmith Project name you entered. If analyses are not yet turned on, go ahead and click the button under the system name to get started.

Congrats! Your AI agent will now be analyzed by Synth.
