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 Collection Events on OpenSea

Description:Emit new filtered events. [See docs](https://docs.opensea.io/reference/retrieving-asset-events)

Version:0.0.3

OpenSea Overview#

The OpenSea API provides a plethora of endpoints that lets you tap into the rich world of NFTs. From fetching detailed asset information to looking up user-specific items, the possibilities for crafting custom Pipedream workflows are vast. This allows you to automate alerts, synchronize NFT collections with external databases, or even analyze market trends programmatically.

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
OpenSea	`opensea`	`app`	This component uses the OpenSea app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
	`timer`	`$.interface.timer`
Contract Address	`contractAddress`	`string`	Collection contract address
Event Type	`eventType`	`string`	Select a value from the drop down menu:`saleslistings`

Trigger Authentication#

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

To connect your OpenSea account to Pipedream, request an API key from OpenSea here.

About OpenSea#

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.

Action Code#

import common from "../../common/common-dynamodb.mjs";
import {
  toSingleLineString,
  attemptToParseJSON,
} from "../../common/utils.mjs";

export default {

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
AWS	`aws`	`app`	This component uses the AWS app.
AWS Region	`region`	`string`	Select a value from the drop down menu.
Table Name	`tableName`	`string`	Select a value from the drop down menu.
Projection Expression	`projectionExpression`	`string`	A string that identifies one or more attributes to retrieve from the specified table or index. If no attribute names are specified, then all attributes will be returned. If any of the requested attributes are not found, they will not appear in the result.
Filter Expression	`filterExpression`	`string`	A string expression that determines which items should be returned. See the docs
Expression Attribute Names	`expressionAttributeNames`	`string`	One or more substitution tokens for attribute names in an expression. Example: `{ "#execs": "execs" }` See the docs
Expression Attribute Values	`expressionAttributeValues`	`string`	One or more values that can be substituted in an expression. Use the : (colon) character in an expression to dereference an attribute value. Example: `{ ":echo": { "S": "echo" }, ":oneh": { "N": "100" } }` See the docs
Limit	`limit`	`integer`	The maximum number of items to evaluate (not necessarily the number of matching items)

Action 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.
