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 Item From Multiple RSS Feeds on RSS

Description:Emit new items from multiple RSS feeds

Version:1.2.7

Key:rss-new-item-from-multiple-feeds

RSS Overview#

The RSS app allows users to automatically fetch and parse updates from web feeds. This functionality is pivotal for staying abreast of content changes or updates from websites, blogs, and news outlets that offer RSS feeds. With Pipedream, you can harness the RSS API to trigger workflows that enable a broad range of automations, like content aggregation, monitoring for specific keywords, notifications, and data synchronization across platforms.

Trigger Code#

            this.$emit(item, meta);
        });
    },
});

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
RSS	`rss`	`app`	This component uses the RSS app.
	`timer`	`$.interface.timer`	How often you want to poll the feed for new items
Feed URLs	`urls`	`string[]`	Enter one or multiple URLs from any public RSS feed. To avoid timeouts, 5 or less URLs is recommended.
Max per Feed	`max`	`integer`	Maximum number of posts per feed to retrieve at one time. Defaults to 20.

Trigger Authentication#

The RSS API does not require authentication.

Execute Signed Transaction on Overledger

Description:Executes a signed transaction by sending it to a blockchain node via Overledger. [See the documentation](https://developers.quant.network/reference/executesignedrequest)

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 Code#

import overledger from "../../overledger.app.mjs";

export default {
  key: "overledger-execute-signed-transaction",
  name: "Execute Signed Transaction",
  description: "Executes a signed transaction by sending it to a blockchain node via Overledger. [See the documentation](https://developers.quant.network/reference/executesignedrequest)",
  version: "0.0.2",
  type: "action",
  props: {
    overledger,
    environment: {
      propDefinition: [
        overledger,
        "environment",
      ],
    },
    requestId: {
      type: "string",
      label: "Request ID",
      description: "The Overledger identifier assigned to the related transaction preparation request. This should be set to the requestId parameter found in the response object of the 'Prepare a Smart Contract Transaction' Overledger action.",
    },
    signedTransaction: {
      type: "string",
      label: "Signed Transaction",
      description: "The raw transaction bytecode after signing. This should be set to the signed parameter found in the response object of the 'Sign a Transaction' Overledger action.",
      optional: true,
    },
  },
  async run({ $ }) {

    const requestBody = {
      requestId: this.requestId,
      signedTransaction: this.signedTransaction,
    };

    const response = await this.overledger.executeSignedTransaction({
      $,
      environment: this.environment,
      data: requestBody,
    });

    $.export("$summary", `Successfully executed signed transaction with Request ID ${this.requestId}`);
    return response;
  },
};

Action Configuration#

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

Label	Prop	Type	Description
Overledger	`overledger`	`app`	This component uses the Overledger app.
Overledger Instance	`environment`	`string`	Select a value from the drop down menu:`{ "label": "Sandbox", "value": "sandbox" }{ "label": "Overledger", "value": "overledger" }`
Request ID	`requestId`	`string`	The Overledger identifier assigned to the related transaction preparation request. This should be set to the requestId parameter found in the response object of the 'Prepare a Smart Contract Transaction' Overledger action.
Signed Transaction	`signedTransaction`	`string`	The raw transaction bytecode after signing. This should be set to the signed parameter found in the response object of the 'Sign a Transaction' Overledger action.

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
