SFTP (key-based auth)
Interact with an SFTP (SSH File Transfer Protocol) Server using a private key for auth
Integrate the SFTP (key-based auth) API with the Snowflake API
Setup the SFTP (key-based auth) API trigger to run a workflow which integrates with the Snowflake API. Pipedream's integration platform allows you to integrate SFTP (key-based auth) and Snowflake remarkably fast. Free for developers.
Popular Ways to Connect SFTP (key-based auth) with Snowflake#
Popular SFTP (key-based auth) and Snowflake Triggers#
Emit new events when files get created, changed or deleted from a remote directory. See the docs
Run a SQL query on a schedule, triggering a workflow for each row of results
Popular SFTP (key-based auth) and Snowflake Actions#
Uploads a file or string in UTF-8 format to the SFTP server. See the documentation
Overview of SFTP (key-based auth)#
The SFTP (key-based auth) app on Pipedream allows you to securely transfer and manage files over a network. It uses SSH for data transfer and provides the same level of security as SSH, without requiring password authentication, making automation workflows more secure and less prone to human error. You can automate file uploads, downloads, synchronization tasks, and efficiently manage your remote files in a serverless environment. Integrating this with other Pipedream-supported apps enables you to craft powerful and secure data flow systems.
Connect SFTP (key-based auth)#
module.exports = defineComponent({
props: {
sftp: {
type: "app",
app: "sftp",
}
},
async run({steps, $}) {
const Client = require('ssh2-sftp-client');
const {
host,
username,
privateKey,
} = this.sftp.$auth
const config = {
host,
username,
privateKey,
}
const sftp = new Client()
await sftp.connect(config)
this.cwd = await sftp.cwd();
return await sftp.end();
},
})
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.
