Details#

This integration uses pre-built, source-available components from Pipedream's GitHub repo. These components are developed by Pipedream and the community, and verified and maintained by Pipedream.

To contribute an update to an existing component or create a new component, create a PR on GitHub. If you're new to Pipedream component development, you can start with quickstarts for trigger span and action development, and then review the component API reference.

New Role on Snowflake

Description:Emit new event when a role is created

Version:0.1.2

Snowflake Overview#

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.

Trigger Code#

import common from "../common.mjs";

export default {
  ...common,
  type: "source",
  key: "snowflake-new-role",
  name: "New Role",
  description: "Emit new event when a role is created",
  version: "0.1.2",
  methods: {
    ...common.methods,
    alwaysRunInSingleProcessMode() {
      return true;
    },
    generateMeta({
      row,
      timestamp: ts,
    }) {
      return {
        id: row.name,
        summary: row.name,
        ts,
      };
    },
    getStatement() {
      return {
        sqlText: "show roles",
      };
    },
  },
};

Trigger Configuration#

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI and CLI.

Label	Prop	Type	Description
Snowflake	`snowflake`	`app`	This component uses the Snowflake app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
	`timer`	`$.interface.timer`	Watch for changes on this schedule

Trigger Authentication#

Snowflake uses API keys for authentication. When you connect your Snowflake account, Pipedream securely stores the keys so you can easily authenticate to Snowflake APIs in both code and no-code steps.

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.

Prepare Smart Contract Transaction on Overledger

Overledger Overview#

The Overledger API by Quant Network allows developers to interact with multiple blockchain networks. It facilitates the creation, reading, and execution of smart contracts and transactions across different blockchains. This API simplifies the complex nature of blockchain interoperability, enabling multi-chain applications (MApps) through a single gateway.

Action Authentication#

Overledger uses OAuth authentication. When you connect your Overledger account, Pipedream will open a popup window where you can sign into Overledger and grant Pipedream permission to connect to your account. Pipedream securely stores and automatically refreshes the OAuth tokens so you can easily authenticate any Overledger API.

Pipedream requests the following authorization scopes when you connect your account:

overledger/read.scope
