How to Get Started with Integrations in Fastn

Fastn makes it simple to connect your app with tools your users already use—like Slack, HubSpot, Shopify, and more. Whether you're automating workflows or embedding integrations into your platform, Fastn helps you do it without heavy backend setup.

Here’s a quick look at how it works:

1. Choose a Connector

Start by selecting a third-party app (like HubSpot or Slack) from Fastn’s Connector Catalog. These connectors are pre-built, so you don’t have to code from scratch.

2. Connect Your Account

Once you’ve selected a connector, sign in to your account (like HubSpot or Slack) to link it with Fastn. You can also use your own app credentials if needed.

3. Create a Flow

Now build a flow to define what should happen. For example, you can:

• Get contacts from HubSpot

• Send a message to Slack

• Sync products to a database

These flows run automatically and help your tools work together without extra effort.

4. Embed the Integration

Want to let your users connect their accounts? Add a widget or button inside your app using Fastn’s UI components. You can:

• Show “Connect” / “Disconnect” buttons

• Run flows directly from your UI

• Track integration status in your dashboard

5. Monitor & Manage

Use the Fastn dashboard to have complete visibility into your integrations and workflows:

• See which users are connected

• Track flow runs, latency, and errors

• Filter data by tenant or connector

What This Means for You

You don’t need to build integrations from scratch or manage OAuth complications. Fastn gives you the infrastructure, templates, and tools—all ready to plug in.
