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
Payhere	`payhere`	`app`	This component uses the Payhere 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.
Integration Name	`integrationName`	`string`	Friendly name of your platform, helps with metrics and debugging
Event Type	`resource`	`string`	Select a value from the drop down menu:`{ "label": "Payment Received", "value": "payment_received" }{ "label": "Subscription Cancelled", "value": "subscription_cancelled" }{ "label": "Subscription Created", "value": "subscription_created" }`

Trigger Authentication#

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

You can find your API key in the integrations section of the merchants admin.

For environment, Payhere provides a sandbox site so you can easily test your integration without using your own money. See docs. If you aren't testing, use the production option.

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 {
  ...common,
  key: "aws-dynamodb-query",

    region: common.props.region,
    tableName: common.props.tableName,
    keyConditionExpression: common.props.keyConditionExpression,
    projectionExpression: common.props.projectionExpression,
    expressionAttributeNames: common.props.expressionAttributeNames,
    expressionAttributeValues: common.props.expressionAttributeValues,
  },
  async run({ $ }) {
    const params = {
      TableName: this.tableName,
      KeyConditionExpression: this.keyConditionExpression,
      ProjectionExpression: this.projectionExpression,
      ExpressionAttributeNames: attemptToParseJSON(this.expressionAttributeNames),
      ExpressionAttributeValues: attemptToParseJSON(this.expressionAttributeValues),

    const response = await this.aws.pagination(
      this.query,
      params,
      "ExclusiveStartKey",
      "LastEvaluatedKey",
    );

    const s = response.Items.length === 1
      ? ""
      : "s";
    $.export("$summary", `Query returned ${response.Items.length} item${s}`);
    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
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.
Key Condition Expression	`keyConditionExpression`	`string`	The condition that specifies the key values for items to be retrieved by the Query action. Example: `partitionKeyName = :partitionkeyval AND sortKeyName = :sortkeyval` See the docs
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.
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

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.
