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.

New ERC20 Transfer (Instant) on l3mbda

Description:Emit new event when a new ERC20 transfer is detected by [l3mbda.](https://l3mbda.com/)

l3mbda Overview#

The l3mbda API provides a platform to run JavaScript functions in the cloud, allowing you to execute code without setting up servers. On Pipedream, you can leverage the l3mbda API to create dynamic, serverless workflows. This enables you to run custom JavaScript functions as part of an automated process, integrate with other APIs, manipulate data, and respond to webhooks.

Trigger Code#

import common from "../common/webhook.mjs";
import events from "../common/events.mjs";
import sampleEmit from "./test-event.mjs";

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
l3mbda	`app`	`app`	This component uses the l3mbda 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.
Sender (Address)	`from`	`string`	Enter to filter transactions by their from (sender) field. Accepts ENS.
Recipient (Address)	`to`	`string`	Enter to filter transactions by their to (receiver) field. Accepts ENS.
Token Contract (Address)	`token`	`string`	Enter to filter transactions by token.
Amount (Token)	`amount`	`string`	Enter to filter transactions by their minimum amount in tokens.

Trigger Authentication#

l3mbda uses OAuth authentication. When you connect your l3mbda account, Pipedream will open a popup window where you can sign into l3mbda and grant Pipedream permission to connect to your account. Pipedream securely stores and automatically refreshes the OAuth tokens so you can easily authenticate any l3mbda API.

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

MySQL Overview#

The MySQL application on Pipedream enables direct interaction with your MySQL databases, allowing you to perform CRUD operations—create, read, update, delete—on your data with ease. You can leverage these capabilities to automate data synchronization, report generation, and event-based triggers that kick off workflows in other apps. With Pipedream's serverless platform, you can connect MySQL to hundreds of other services without managing infrastructure, crafting complex code, or handling authentication.

Action Code#

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

export default {
  key: "mysql-execute-query",
  name: "Execute Query",
  description: "Find row(s) via a custom query. [See the docs here](https://dev.mysql.com/doc/refman/8.0/en/select.html)",
  type: "action",
  version: "2.0.5",
  props: {
    mysql,
    table: {
      description: "The table where the query will be executed",
      propDefinition: [
        mysql,
        "table",
      ],
    },
    condition: {
      propDefinition: [
        mysql,
        "whereCondition",
      ],
    },
    values: {
      propDefinition: [
        mysql,
        "whereValues",
      ],
    },
  },
  async run({ $ }) {
    const {
      table,
      condition,
      values,
    } = this;

    const numberOfQuestionMarks = condition?.match(/\?/g)?.length;

    if (!numberOfQuestionMarks) {
      throw new Error("No valid condition provided. At least one question mark character ? must be provided.");
    }

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

    if (values.length !== numberOfQuestionMarks) {
      throw new Error("The number of values provided does not match the number of question marks ? in the condition.");
    }

    const result = await this.mysql.findRows({
      table,
      condition,
      values,
    });

    $.export("$summary", `Successfully found ${result.length} row(s) from table ${table}`);

    return result;
  },
};

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
MySQL	`mysql`	`app`	This component uses the MySQL app.
Table	`table`	`string`	Select a value from the drop down menu.
Where condition	`condition`	`string`	In this expression you can write your own conditions (eg. `column1 = ? or column2 = ?`). Depending on the number of `?` symbols likewise you need to add the same number of values.
Values	`values`	`string[]`	This is the list of values that will match every `?` symbol in the where expression. If you want to build yourself the values (eg. `{{["string1", "string2"]}}`)

Action Authentication#

MySQL uses API keys for authentication. When you connect your MySQL account, Pipedream securely stores the keys so you can easily authenticate to MySQL 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 MySQL 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.
