2. Select a AWS Region
3. Select a S3 Bucket Name
4. Configure Ignore Delete Markers
Configure the Prepare Smart Contract Transaction action
1. Connect your Overledger account
2. Select a Overledger Instance
3. Select a Location Technology
4. Configure Signing Account ID
5. Configure Smart Contract ID
6. Configure Function Name
7. Optional- Configure Input Parameters

Send a test event to validate your setup
Turn on the trigger

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.

Trigger#

New Deleted S3 File on AWS

Description:Emit new event when a file is deleted from a S3 bucket

Version:0.1.2

Key:aws-s3-deleted-file

AWS Overview#

The AWS API unlocks endless possibilities for automation with Pipedream. With this powerful combo, you can manage your AWS services and resources, automate deployment workflows, process data, and react to events across your AWS infrastructure. Pipedream offers a serverless platform for creating workflows triggered by various events that can execute AWS SDK functions, making it an efficient tool to integrate, automate, and orchestrate tasks across AWS services and other apps.

Trigger Code#

import base from "../common/s3.mjs";

export default {
  ...base,
  type: "source",
  key: "aws-s3-deleted-file",
  name: "New Deleted S3 File",
  description: "Emit new event when a file is deleted from a S3 bucket",
  version: "0.1.2",
  dedupe: "unique",
  props: {
    ...base.props,
    ignoreDeleteMarkers: {
      type: "boolean",
      label: "Ignore Delete Markers",
      description: "When ignoring delete markers this will only emit events for permanently deleted files",
      default: false,
    },
  },
  methods: {
    ...base.methods,
    getEvents() {
      return [
        this.ignoreDeleteMarkers
          ? "s3:ObjectRemoved:Delete"
          : "s3:ObjectRemoved:*",
      ];
    },
    generateMeta(data) {
      const { "x-amz-request-id": id } = data.responseElements;
      const { key } = data.s3.object;
      const { eventTime: isoTimestamp } = data;
      return {
        id,
        summary: `Deleted file: '${key}'`,
        ts: Date.parse(isoTimestamp),
      };
    },
  },
};

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
AWS	`aws`	`app`	This component uses the AWS app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
N/A	`http`	`$.interface.http`	This component uses `$.interface.http` to generate a unique URL when the component is first instantiated. Each request to the URL will trigger the `run()` method of the component.
AWS Region	`region`	`string`	Select a value from the drop down menu.
S3 Bucket Name	`bucket`	`string`	Select a value from the drop down menu.
Ignore Delete Markers	`ignoreDeleteMarkers`	`boolean`	When ignoring delete markers this will only emit events for permanently deleted files

Trigger Authentication#

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

Follow the AWS Instructions for creating an IAM user with an associated access and secret key.

As a best practice, attach the minimum set of IAM permissions necessary to perform the specific task in Pipedream. If your workflow only needs to perform a single API call, you should create a user and associate an IAM group / policy with permission to do only that task. You can create as many linked AWS accounts in Pipedream as you'd like.

Enter your access and secret key below.

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 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" }`

Signing Account ID	`signingAccountId`	`string`	The blockchain account ID/address that will be sending this transaction
Smart Contract ID	`smartContractId`	`string`	The ID/address of the smart contract to interact with.
Function Name	`functionName`	`string`	The name of the function to call on the smart contract.
Input Parameters	`inputParameters`	`string[]`	The input parameters for the smart contract function, in JSON format.

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
