AMQP Component

Send and receive messages on an AMQP-based message broker

Component key: amqp

Description

The Advanced Message Queuing Protocol (AMQP) is a standard protocol for interacting with message brokers and queueing platforms. It is used by many common message broker services like Azure Event Hubs, Apache Qpid, RabbitMQ and more.

This component allows you to manage messages on an AMQP-based queue.

AMQP Connections

Actions

Acknowledge Message

Acknowledge a previously fetched message | key: acknowledgeMessage

Input	Notes
Input Connection connection / Required	Notes
Input Message string / Required	Notes An AMQP message. This must reference the results of a previous 'Get Message' step

Check AMQP Connection

Verify that an AMQP server is available, and return the server's connection information. This is helpful for debugging purposes. | key: checkConnection

Input	Notes
Input Connection connection / Required	Notes

Output Example Payload

{  "data": {    "host": "amqp.example.com",    "copyright": "Copyright (c) 2007-2022 VMware, Inc. or its affiliates.",    "information": "Licensed under the MPL 2.0. Website: https://rabbitmq.com",    "platform": "Erlang/OTP 24.2.1",    "product": "RabbitMQ",    "version": "3.9.13",    "connection": {      "host": "amqp.example.com",      "port": "5672",      "vhost": "example/vhost",      "password": "myPassword",      "protocol": "amqp",      "username": "myUsername"    }  }}

Get Message

Receives a message from an AMQP-based queue | key: getMessage

Input	Default	Notes	Example
Input Acknowledge Message boolean	Default true	Notes Automatically mark the message received as "Acknowledged"	Example
Input Connection connection / Required	Default	Notes	Example
Input Queue Name string / Required	Default	Notes Provide the name of the queue you would like to interact with.	Example myQueue

This action will return a message from a given queue, if a message is available to get. If no message is available, this action will return null.

Use a Branch on Expression step to branch based on whether or not a message was fetched. You can check if the results of this step are non-null using the exists operator.

You have two options for marking a message "acknowledged":

1. You can set the Acknowledge Message input to true. This will cause the message to be acknowledged immediately, and the message will be removed from the queue.
2. You can choose to not acknowledge the message immediately, but instead process the message and then pass the message to a Acknowledge Message step instead. This option is helpful if you would like to ensure the message is processed completely before removing it from the queue.

Output Example Payload

{  "data": {    "fields": {      "deliveryTag": 1,      "redelivered": true,      "routingKey": "classic",      "messageCount": 10    },    "properties": {      "contentType": "text",      "contentEncoding": "",      "deliveryMode": "exampleMode",      "priority": "High",      "correlationId": "exampleId",      "replyTo": "",      "expiration": "",      "messageId": "exampleId",      "timestamp": "Fri, 06 Aug 2021 00:00:00 GMT",      "type": "Buffer",      "userId": "exampleId",      "appId": "exampleId",      "clusterId": "exampleId"    },    "content": {      "type": "Buffer",      "data": [        69,        120,        97,        109,        112,        108,        101      ]    },    "message": "Example Message Content"  }}
