# Flow block in Amazon Connect: Set disconnect flow
Set disconnect flow

This topic defines the flow block for specifying which flow to run when a call is disconnected during a contact.

## Description

+ Specifies which flow to run after a disconnect event during a contact. 

  A disconnect event is when:
  + A chat, or task is disconnected.
  + A task is disconnected as a result of a flow action.
  + A task expires. The task is automatically disconnected when it completes its expiry timer. The default is 7 days and task expiry is configurable up to 90 days. 

  When the disconnect event occurs, the corresponding flow runs. 
+ Here are examples of when you might use this block:
  + Run post-contact surveys. For example, the agent asks the customer to remain on the line for a post-call survey. The agent hangs up and a disconnect flow is run. In the disconnect flow, the customer is asked a set of questions using the [Get customer input](get-customer-input.md) block. Their answers are uploaded using an [AWS Lambda function](invoke-lambda-function-block.md) block to an external customer feedback database. The customer is thanked and disconnected.

    For more information about creating post-contact surveys, see this blog: [Easily create and visualize post chat surveys with Amazon Connect and Amazon Lex](https://aws.amazon.com/blogs/contact-center/easily-create-and-visualize-post-chat-surveys-with-amazon-connect-and-amazon-lex/). And check out this workshop: [Building a contact survey solution for Amazon Connect](https://catalog.workshops.aws/amazon-connect-contact-survey/en-US).
  + In a chat scenario, if a customer stops responding to the chat, use this block to decide whether to run the disconnect flow and call a [Wait](wait.md) block, or end the conversation.
  + In task scenarios where a task may not be completed in 7 days, use this block to run a disconnect flow to determine whether the task should be re-queued, or completed/[disconnected](disconnect-hang-up.md) by a flow action.

**Tip**  
It's not possible to play a audio prompt to the agent or invoke a flow when the customer disconnects. After the customer disconnects, the flow ends and the agents starts After Call Work (ACW) for that contact.
