# Before You begin Before using the AMQP Consumer step, be aware of the following conditions: * This step uses and requires the AMQP 0-9-1 messaging protocol. * You must have an AMQP 0-9-1 compatible broker (such as [RabbitMQ](https://www.rabbitmq.com/)) available before you configure this step. * Within a transformation, you can use the AMQP Consumer step alone to ingest messages from any AMQP producer or broker. The [AMQP Producer](/pdia-data-integration/9.3-data-integration/pdi-transformation-steps-reference-overview/amqp-producer.md) step is not required. If you want to use both steps together (whether in the same or in a separate transformation), then some of the settings you specify in the Consumer step must match certain settings defined in the Producer step. The Tab sections below explain which settings must match. * Although you can set up this step to work with an existing AMQP message queue, you can also use this step to create a new AMQP message queue. For more information, see [Create a new AMQP Message Queue](/pdia-data-integration/9.3-data-integration/pdi-transformation-steps-reference-overview/amqp-consumer/options-amqp-consumer/create-a-new-amqp-message-queue.md). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
