Getting Started#

This integration creates a workflow with a Line trigger and PostgreSQL action. When you configure and deploy the workflow, it will run on Pipedream's servers 24x7 for free.

Select this integration
Configure the New Message Received trigger
1. Connect your Line account
2. Configure Channel Access Token
Configure the Find Row With Custom Query action
1. Connect your PostgreSQL account
2. Configure SQL Query
3. Optional- Configure Values

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 Message Received on Line

Description:Emit new event for every received message in a channel. [See docs here](https://developers.line.biz/en/docs/messaging-api/building-bot/#page-title)

Line Overview#

The Line API facilitates interaction with Line's messaging platform, enabling developers to send messages, manage user data, and leverage Line's rich social features within their applications. By using Pipedream, an integration platform, you can automate interactions with the Line API, connect to countless other services, and orchestrate complex workflows without managing servers.

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
Line	`line`	`app`	This component uses the Line 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.
Channel Access Token	`channelAccessToken`	`string`	The access token of a group or room. Please refer to the Line doc here to get the channel access token

Trigger Authentication#

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

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

PostgreSQL Overview#

On Pipedream, you can leverage the PostgreSQL app to create workflows that automate database operations, synchronize data across platforms, and react to database events in real-time. Think handling new row entries, updating records from webhooks, or even compiling reports on a set schedule. Pipedream's serverless platform provides a powerful way to connect PostgreSQL with a variety of apps, enabling you to create tailored automation that fits your specific needs.

Action Code#

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

export default {
  name: "Find Row With Custom Query",
  key: "postgresql-find-row-custom-query",
  description: "Finds a row in a table via a custom query. [See the documentation](https://node-postgres.com/features/queries)",

    query: {
      propDefinition: [
        postgresql,
        "query",
      ],
    },
    values: {
      propDefinition: [
        postgresql,
        "values",
      ],
    },
  },
  async run({ $ }) {
    const {
      query,
      values = [],
    } = this;

    if (!Array.isArray(values)) {
      throw new Error("No valid values provided. The values property must be an array.");
    }

    if (this.values) {
      const numberOfValues = query?.match(/\$/g)?.length || 0;
      if (values.length !== numberOfValues) {
        throw new Error("The number of values provided does not match the number of values in the query.");
      }
    }

    if (!query.toLowerCase().includes("select")) {
      throw new Error("Need be a `SELECT` statement query. Read more about [SELECT queries here](https://www.w3schools.com/sql/sql_select.asp)");
    }

    try {
      const res = await this.postgresql.executeQuery({
        text: query,
        values,
      });
      $.export("$summary", "Successfully executed query");
      return res;
    } catch (error) {
      let errorMsg = "Query not executed due to an error. ";
      errorMsg += `${error}`.includes("SSL verification failed")
        ? "This could be because SSL verification failed. To resolve this, reconnect your account and set SSL Verification Mode: Skip Verification, and try again."
        : `${error}`;
      throw new Error(errorMsg);
    }
  },
};

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
PostgreSQL	`postgresql`	`app`	This component uses the PostgreSQL app.
SQL Query	`query`	`string`	Your custom SQL Query using `$1`, `$2`... to represent values (eg. `INSERT INTO users(name, email) VALUES($1, $2)`
Values	`values`	`string[]`	List of values represented in your SQL Query above

Action Authentication#

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

Connecting to Restricted Databases

Either enable the shared static IP for this account below, or configure a VPC to deploy any workflow in your workspace to a private network with a dedicated static IP. Learn more in our docs.

SSL Setup

Configure SSL on your PostgreSQL database by providing the CA (Certificate Authority), and choosing between Full Verification, Verify Certificate Authority (CA), or Skip Verification. Skipping verification is not recommended as this has serious security implications.
