Connector Types & Setup

Connectors in Fastn

Connectors in the Fastn platform enable you to integrate and interact with external systems such as APIs, databases, or custom logic. They act as bridges that bring external data into your flows or send processed data out.

Using Connectors

Connectors are reusable components that simplify the process of integrating third-party services. Once added to a flow, they can perform operations like fetching data, transforming it, or saving it to an external system. Each connector includes input and output schemas to ensure data consistency throughout your flow.

Types of Connectors

In Fastn, connectors let your flows interact with external apps, APIs, and data sources. They act as bridges between Fastn and the outside world, enabling powerful automations across tools and services.

Fastn supports two main types of connectors:

Community Connectors

These are prebuilt, ready-to-use connectors that let you integrate popular apps like Slack, Google Docs, Notion, Salesforce, HubSpot, and many more; with 140+ supported apps and counting.

Community connectors make it easy to connect to tools your team already uses, so you can trigger flows, pull in data, or take actions in those apps without writing any custom code.

For example, a Shopify connector can be used to interact with various Shopify APIs like getAllProducts or createProduct, making it easy to retrieve or update product data directly within your flow.

Custom Connectors

If you need something more specific or want to integrate a system not covered by our community set, Fastn lets you build custom connectors. These include:

i. Function Connector

Function connectors allow you to define custom logic for data processing. You can specify both the input and output schemas, making them ideal for manipulating data within your flow.

ii. HTTP API Connector

This type of connector integrates data from external sources that expose HTTP-based APIs. It enables communication with web services, allowing you to retrieve or manipulate data on remote servers through HTTP requests.

iii. Database Connector

Database connectors enable integration with external databases. They allow you to execute queries, retrieve data, or update records, all within your flow logic.
