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.

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.

Trigger Code#

import { DEFAULT_POLLING_SOURCE_TIMER_INTERVAL } from "@pipedream/platform"; import maxBy from "lodash.maxby"; import common from "../common/common.mjs"; import sampleEmit from "./test-event.mjs"; export default { ...common, key: "discord_bot-new-thread-message", name: "New Thread Message", description: "Emit new event for each thread message posted.", type: "source", version: "1.0.0", dedupe: "unique", // Dedupe events based on the Discord message ID props: { ...common.props, db: "$.service.db", timer: { type: "$.interface.timer", default: { intervalSeconds: DEFAULT_POLLING_SOURCE_TIMER_INTERVAL, }, }, ignoreBotMessages: { type: "boolean", label: "Ignore Bot Messages", description: "Set to `true` to only emit messages NOT from the configured Discord bot", optional: true, }, }, hooks: { async deploy() { if (this.ignoreBotMessages) { const { id } = await this.getBotProfile(); this._setBotId(id); } }, }, async run({ $ }) { // We store a cursor to the last message ID let lastMessageIDs = this._getLastMessageIDs(); const botId = this.ignoreBotMessages ? this._getBotId() : null; const { threads } = await this.discord.listThreads({ $, guildId: this.guildId, }); // If this is our first time running this source, // get the last N messages, emit them, and checkpoint for (const channel of threads) { let lastMessageID; let messages = []; const channelId = channel.id; if (!lastMessageIDs[channelId]) { messages = await this.discord.getMessages({ $, channelId, params: { limit: 100, }, }); lastMessageID = messages.length ? maxBy(messages, (message) => message.id).id : 1; } else { let newMessages = []; do { newMessages = await this.discord.getMessages({ $, channelId, params: { after: lastMessageIDs[channelId], }, }); messages = messages.concat(newMessages); lastMessageID = newMessages.length ? maxBy(newMessages, (message) => message.id).id : lastMessageIDs[channelId]; lastMessageIDs[channelId] = lastMessageID; } while (newMessages.length); } // Set the new high water mark for the last message ID // for this channel lastMessageIDs[channelId] = lastMessageID; if (!messages.length) { console.log(`No new messages in thread ${channelId}`); continue; } if (botId) { messages = messages.filter((message) => message.author.id !== botId); } console.log(`${messages.length} new messages in thread ${channelId}`); messages.reverse().forEach((message) => { if (!message.content) { return; } this.$emit(message, { id: message.id, // dedupes events based on this ID summary: `A new message with Id: ${message.id} was posted in thread ${channelId}.`, ts: Date.parse(message.timestamp), }); }); } // Set the last message ID for the next run this._setLastMessageIDs(lastMessageIDs); }, sampleEmit, };

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
Discord Bot	`discord`	`app`	This component uses the Discord Bot app.
Guild	`guildId`	`string`	Select a value from the drop down menu.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
	`timer`	`$.interface.timer`
Ignore Bot Messages	`ignoreBotMessages`	`boolean`	Set to `true` to only emit messages NOT from the configured Discord bot

Trigger 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.

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.

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)"); } const res = await this.postgresql.executeQuery({ text: query, values, errorMsg: "Query not executed due to an error.

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
