RabbitMQ bindings for Azure Functions overview

Note

The RabbitMQ bindings are only fully supported on Premium and Dedicated App Service plans. Flex Consumption and Consumption plans aren't yet supported.
RabbitMQ bindings are only supported for Azure Functions version 3.x and later versions.

Azure Functions integrates with RabbitMQ via triggers and bindings. The Azure Functions RabbitMQ extension allows you to send and receive messages using the RabbitMQ API with Functions.

Prerequisites

Before working with the RabbitMQ extension, you must set up your RabbitMQ endpoint. To learn more about RabbitMQ, see the getting started page.

Install extension

The extension NuGet package you install depends on the C# mode you're using in your function app:

Isolated worker model

Functions execute in an isolated C# worker process. To learn more, see Guide for running C# Azure Functions in an isolated worker process.

Add the extension to your project by installing this NuGet package.

In-process model

Important

Support will end for the in-process model on November 10, 2026. We highly recommend that you migrate your apps to the isolated worker model for full support.

Functions execute in the same process as the Functions host. To learn more, see Develop C# class library functions using Azure Functions.

Add the extension to your project by installing this NuGet package.

Install bundle

The RabbitMQ extension is part of an extension bundle, which is specified in your host.json project file. When you create a project that targets version 3.x or later, you should already have this bundle installed. To learn more, see extension bundle.
