# Allowlist

> Understand Fyno Allowlist configurations. Securely register, verify, and map external HTTP URLs and AWS SQS queues to capture delivery report callbacks and execute custom API integrations from Workflows.

## Overview

The **Allowlist** is a registry of verified external destinations, such as Webhook URLs and SQS queues, that can securely interact with Fyno. These destinations must be added and verified before they can be used inside workflows, delivery reporting, or other integrations within the platform.

The Allowlist module helps ensure that only trusted and validated endpoints can exchange data with Fyno, improving security and reducing the risk of unauthorized communication.

## Why is an Allowlist Required?

Fyno uses Allowlists to securely manage communication between the platform and external systems. You need to configure an Allowlist in the following scenarios:

| Use Case                              | Description                                                                    |
| :------------------------------------ | :----------------------------------------------------------------------------- |
| **Receive Delivery Reports**          | Receive notification delivery updates, callbacks, or event statuses from Fyno. |
| **Call External APIs from Workflows** | Trigger APIs hosted outside Fyno from within workflows.                        |
| **Third-Party Integrations**          | Send or receive data from external applications or services.                   |
| **Workflow Event Updates**            | Exchange workflow execution events and callbacks securely.                     |

## Supported Allowlist Types

Fyno currently supports the following Allowlist types:

| Type                    | Description                                                    |
| :---------------------- | :------------------------------------------------------------- |
| [HTTP](./allowlist-url) | Used for API integrations, callbacks, and delivery reports.    |
| [SQS](./allowlist-sqs)  | Used for queue-based integrations and asynchronous processing. |

## Accessing the Allowlist Module

To access and manage Allowlists:

1. Navigate to **Workspace Settings**.
2. Open the **Allowlist** tab.

This section allows you to create, verify, edit, and manage all configured endpoints for your workspace.

## Active and Inactive Status

Allowlist entries can exist in different operational states:

| Status       | Description                                                        |
| :----------- | :----------------------------------------------------------------- |
| **Active**   | Endpoint is verified and available for workflows and integrations. |
| **Inactive** | Endpoint is disabled and cannot be used.                           |

> :::NOTE:
> Only **Active** Allowlists can be selected during workflow configuration or delivery report setup.
> :::

## Prerequisites

Before creating an Allowlist URL, ensure the following requirements are met:

| Requirement         | Description                                                                      |
| :------------------ | :------------------------------------------------------------------------------- |
| **Public Endpoint** | The endpoint must be publicly accessible over the internet.                      |
| **HTTPS Support**   | HTTPS is strongly recommended to guarantee secure, encrypted data communication. |
