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

Description:Emit new event each time a Telegram message is created or updated.
Version:0.1.3
Key:telegram_bot_api-message-updates

Telegram Bot Overview

With the Telegram Bot API, you can build bots that perform a variety of tasks,
including:

  • Sending and receiving messages
  • Social networking
  • Content management
  • File sharing
  • Location sharing
  • Bot administration
  • And more!

Trigger Code

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

export default {
  ...base,
  key: "telegram_bot_api-message-updates",
  name: "New Message Updates (Instant)",
  description: "Emit new event each time a Telegram message is created or updated.",
  version: "0.1.3",
  type: "source",
  dedupe: "unique",
  methods: {
    ...base.methods,
    getMeta(event, message) {
      return {
        id: event.update_id,
        summary: message.text,
        ts: new Date(message.edit_date ?? message.date),
      };
    },
    getEventTypes() {
      return [
        "message",
        "edited_message",
      ];
    },
    processEvent(event) {
      const message = event.edited_message ?? event.message;
      this.$emit(event, this.getMeta(event, message));
    },
  },
};

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.
LabelPropTypeDescription
Telegram BottelegramBotApiappThis component uses the Telegram Bot app.
N/Adb$.service.dbThis component uses $.service.db to maintain state between executions.
N/Ahttp$.interface.httpThis 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.

Trigger Authentication

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

To use the Telegram Bot API, you must first create a new bot by chatting with the BotFather.

After you create your bot, copy the bot token and add it below.

Action

Description:Executes a custom query you provide. [See Docs](https://node-postgres.com/features/queries)
Version:0.0.7
Key:postgresql-execute-custom-query

PostgreSQL Overview

Assuming you want a few paragraphs on what you can do with the PostgreSQL API:

The following examples demonstrate some of the things that can be done with the
PostgreSQL API:

  • Developing a custom storage engine for PostgreSQL
  • Adding a new data type to PostgreSQL
  • Creating a new function for PostgreSQL
  • Building a graphical user interface for PostgreSQL
  • And much more!

Action Code

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

export default {
  name: "Execute Custom Query",
  key: "postgresql-execute-custom-query",
  description: "Executes a custom query you provide. [See Docs](https://node-postgres.com/features/queries)",
  version: "0.0.7",
  type: "action",
  props: {
    postgresql,
    query: {
      propDefinition: [
        postgresql,
        "query",
      ],
    },
    values: {
      propDefinition: [
        postgresql,
        "values",
      ],
    },
    rejectUnauthorized: {
      propDefinition: [
        postgresql,
        "rejectUnauthorized",
      ],
    },
  },
  async run({ $ }) {
    const {
      query,
      values = [],
      rejectUnauthorized,
    } = this;

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

    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.");
    }

    try {
      const res = await this.postgresql.executeQuery({
        text: query,
        values,
      }, rejectUnauthorized);
      $.export("$summary", "Successfully executed query");
      return res;
    } catch (error) {
      throw new Error(`
        Query not executed due to an error. ${error}.
        This could be because SSL verification failed, consider changing the Reject Unauthorized prop and try again.
      `);
    }
  },
};

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.

LabelPropTypeDescription
PostgreSQLpostgresqlappThis component uses the PostgreSQL app.
SQL Queryquerystring

Your custom SQL Query using $1, $2... to represent values (eg. INSERT INTO users(name, email) VALUES($1, $2)

If not false, the server certificate is verified against the list of supplied CAs. If you get the error Connection terminated unexpectedly try to set this prop as false

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.

Before you connect to your PostgreSQL database from Pipedream, please make sure your database is either:

  1. Accessible from the public internet (You may need to add a firewall rule on 0.0.0.0/0 on port 3306), or

  2. Accessible from an SSH server that you route PostgreSQL requests through

After that, enter the following values:

  • host: The hostname or IP address of your PostgreSQL server
  • port: 3306, unless you run PostgreSQL on a different port
  • username: The account username to log in
  • password: The account password to log in
  • database: The name of the PostgreSQL database to run queries against
