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 for every received message in a channel. [See docs here](https://developers.line.biz/en/docs/messaging-api/building-bot/#page-title)
Version:0.0.2
Key:line-new-message-received

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.
LabelPropTypeDescription
LinelineappThis component uses the Line 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.
Channel Access TokenchannelAccessTokenstring

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:

About Line

Line is a communication app that connects people, services, and information.

Action

Description:Assign a role to a user. Remember that your bot requires the `MANAGE_ROLES` permission. [See the docs here](https://discord.com/developers/docs/resources/guild#add-guild-member-role)
Version:0.0.12
Key:discord_bot-add-role

Discord Bot Overview

The Discord Bot API unlocks the power to interact with Discord users and channels programmatically, making it possible to automate messages, manage servers, and integrate with other services. With Pipedream's serverless platform, you can create complex workflows that respond to events in Discord, process data, and trigger actions in other apps. This opens up opportunities for community engagement, content moderation, analytics, and more, without the overhead of managing infrastructure.

Action Code

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

const { discord } = common.props;

export default {
  ...common,
  key: "discord_bot-add-role",
  name: "Add Role",
  description: "Assign a role to a user. Remember that your bot requires the `MANAGE_ROLES` permission. [See the docs here](https://discord.com/developers/docs/resources/guild#add-guild-member-role)",
  type: "action",
  version: "0.0.12",
  props: {
    ...common.props,
    userId: {
      propDefinition: [
        discord,
        "userId",
        ({ guildId }) => ({
          guildId,
        }),
      ],
    },
    roleId: {
      propDefinition: [
        discord,
        "roleId",
        ({
          guildId, userId,
        }) => ({
          guildId,
          userId,
          isAddRole: true,
        }),
      ],
    },
  },
  async run({ $ }) {
    const response = await this.discord.addGuildMemberRole({
      $,
      guildId: this.guildId,
      userId: this.userId,
      roleId: this.roleId,
    });

    if (!response) {
      return {
        id: this.roleId,
        success: true,
      };
    }

    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.

LabelPropTypeDescription
Discord BotdiscordappThis component uses the Discord Bot app.
GuildguildIdstringSelect a value from the drop down menu.
UseruserIdstringSelect a value from the drop down menu.
RoleroleIdstringSelect a value from the drop down menu.

Action Authentication

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

This app allows you to use the Discord API using your own Discord bot. If you don't want to use a custom bot, and you just need to use the Discord API, exit this screen and use the Discord app, instead.


If you want to use your own Discord bot, but haven't created one yet, see these instructions or watch this video. You'll need to add this bot to your server(s) to make successful API requests.

Once you've created your bot, you'll find the Bot token within the Bot section of your app. Enter that token below.
