Allowlist | Fyno Documentation

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	Used for API integrations, callbacks, and delivery reports.
SQS	Used for queue-based integrations and asynchronous processing.

Accessing the Allowlist Module

To access and manage Allowlists:

Navigate to Workspace Settings.
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.
