Integrate the AirNow API with the Snowflake API

The AirNow API provides access to real-time air quality data from across the United States, offering insights into the AQI (Air Quality Index) for various pollutants. With this data, developers can create applications that inform users about the air quality in their immediate environment or trigger actions based on changes in pollution levels. On Pipedream, one can leverage AirNow's data to automate notifications, integrate environmental data into smart home systems, or even drive data analysis and reporting for health and safety monitoring.

Connect AirNow#

import { axios } from "@pipedream/platform"
export default defineComponent({
  props: {
    airnow: {
      type: "app",
      app: "airnow",
    }
  },
  async run({steps, $}) {
    return await axios($, {
      url: `https://www.airnowapi.org/aq/forecast/zipCode/`,
      params: {
        format: `application/json`,
        API_KEY: `${this.airnow.$auth.api_key}`,
        zipCode: `YOUR_ZIP_CODE`,
      },
    })
  },
})

Overview of Snowflake#

Snowflake offers a cloud database and related tools to help developers create robust, secure, and scalable data warehouses. See Snowflake's Key Concepts & Architecture.

Getting Started

1. Create a user, role and warehouse in Snowflake

Snowflake recommends you create a new user, role, and warehouse when you integrate a third-party tool like Pipedream. This way, you can control permissions via the user / role, and separate Pipedream compute and costs with the warehouse. You can do this directly in the Snowflake UI.

We recommend you create a read-only account if you only need to query Snowflake. If you need to insert data into Snowflake, add permissions on the appropriate objects after you create your user.

2. Enter those details in Pipedream

Visit https://pipedream.com/accounts. Click the button to Connect an App. Enter the required Snowflake account data.

You'll only need to connect your account once in Pipedream. You can connect this account to multiple workflows to run queries against Snowflake, insert data, and more.

3. Build your first workflow

Visit https://pipedream.com/new to build your first workflow. Pipedream workflows let you connect Snowflake with 1,000+ other apps. You can trigger workflows on Snowflake queries, sending results to Slack, Google Sheets, or any app that exposes an API. Or you can accept data from another app, transform it with Python, Node.js, Go or Bash code, and insert it into Snowflake.
