An Intermediate Message Catch Event object pauses a [Request](/v1/docs/requests-and-cases#what-is-a-request) until that object receives a specific message. The purpose of the message transfer is to send data between Requests running from the same Process model since each Pool object represents its own Request with its own distinct Request data.

The message may originate from any of the following:

- **Intermediate Message Throw Event object:** An [Intermediate Message Throw Event](/v1/docs/intermediate-message-throw-event) object sends a message to the Intermediate Message Catch Event object that has paused its in-progress Request until the Intermediate Message Catch Event object receives its message. Use this functionality to resume workflow to the Request using the Intermediate Message Catch Event object from another Request. If the Intermediate Message Catch Event object is in the same Process model as the Intermediate Message Throw Event object for which it listens for its message, these objects must be in separate Pool objects since each Pool object has its own Request.
- **Message End Event object:** A [Message End Event](/v1/docs/message-end-event) object sends a message to the Intermediate Message Catch Event. Use this functionality to resume workflow to the Process Request using the Intermediate Message Catch Event object when the Request that sends the message completes. If the Intermediate Message Catch Event object is in the same Process model as the Message End Event object for which it listens for its message, these objects must be in separate Pool objects.
- **Third-party service:** A third-party service such as a CRM may send a message via [our API](https://developers.processmaker.com/v/api/) to the Intermediate Message Catch Event, thereby resuming workflow for that Request.

A Message Flow object can connect from the object sending the message to the Intermediate Message Catch Event object. Ensure that Intermediate Message Catch Event object and its triggering object are in different Pool objects. When configuring the Intermediate Message Catch Event object during Process modeling, select which message from the triggering object sends to the Intermediate Message Catch Event object.

An Intermediate Message Catch Event object functions as follows during a Request:

1. Workflow in the Request using the Intermediate Message Catch Event object pauses when it reaches this event. The Intermediate Message Catch Event object waits for a message based on that message's name. The message name is a placeholder for the message.
2. The Intermediate Message Throw Event object or Message End Event object triggers.
3. That triggering object sends its message containing Request data to the Intermediate Message Catch Event object.
4. If the message name matches that for which the Intermediate Message Catch Event object is listening, then that object triggers; workflow resumes in that Request. Otherwise, the Intermediate Message Catch Event object ignores the message.

Consider the following example how the Intermediate Message Catch Event object functions. This example uses the Intermediate Message Throw Event object in an overly simple purchase request and order fulfillment Process model. The Process model contains two Processes, each within its own Pool object. Each Process may potentially run its own Request.

Simple Process model example to demonstrate how an Intermediate Message Catch Event functions

The Intermediate Message Catch Event object (labeled "Catch from Order") is in the second Pool, "Purchase Fulfillment."

After the "Purchase Fulfillment" Request starts, the following occurs:

1. Workflow delays after the "Preparation" Form Task object.
2. When the Intermediate Message Throw Event object triggers from the "Purchase Order" Request (labeled "Throw to Fulfillment"), it sends its message to the Intermediate Message Catch Event object in the "Purchase Fulfillment" Request. Workflow continues in the "Purchase Order" Request to the End Event object.
3. In the "Purchase Fulfillment" Request, the Intermediate Message Catch Event object triggers and receives the Intermediate Message Throw Event object's message.
4. Workflow resumes in the "Purchase Fulfillment" Request.

3. In the **Name** setting, edit the selected object's name and then press **Enter**.

#### Select the Object from Which to Listen for a Message

An Intermediate Message Catch Event object pauses a Request until that object receives a message from either an Intermediate Message Throw Event object or a Message End Event object (but not both) located in a different Pool object than the Intermediate Message Catch Event object receiving the message. After the Intermediate Message Catch Event object receives its message, that object triggers. Select from which object to listen for a message based on the Intermediate Message Throw Event or Message End Event object's **Message Name** setting value.

Follow these steps to select the object from which to listen for a message:

1. Select the Intermediate Message Catch Event object from the Process model in which to configure how it is triggered.
2. Ensure that the **Configuration** panel displays. If not, [show it](/v1/docs/show-configuration-settings-for-a-process-model-object). Panels to configure this object display.
3. Expand the **Configuration** panel if it is not presently expanded, and then locate the **Listen For Message** setting. ![](https://cdn.document360.io/2d311614-fcb7-4424-8b4c-d4d3091eebeb/Images/Documentation/d7e23b73-6404-401c-a8d5-b36eb55705e3.png)

### Advanced Panel Settings

#### Edit the Node's Identifier Value

Process Modeler automatically assigns a unique value to each Process node added to a Process model. However, a node's identifier value can be changed if it is unique to all other nodes in the Process model, including the Process model's identifier value.

All identifier values for all nodes in the Process model must be unique.

Follow these steps to edit the identifier value for an Intermediate Message Catch Event object:

1. Select the Intermediate Message Catch Event object from the Process model in which to edit its identifier value.
2. Ensure that the **Configuration** panel displays. If not, [show it](/v1/docs/show-configuration-settings-for-a-process-model-object). Panels to configure this object display.
3. Expand the **Advanced** panel if it is not presently expanded. The **Node Identifier** setting displays. This is a required setting.
