# Use case guide

### How to captue the ticket assigned event?

**Use case:** After creating a ticket and assigning to an agent, we need to invoke an API based on the response stored in the **Raise a Ticket** node.

We recieve ```ticket-assigned-bot event```. To activate this event:

1. Store the response of the [Raise Ticket node](https://docs.yellow.ai/docs/platform_concepts/studio/build/nodes/action-nodes#17-raise-ticket) in a variable.

2. Call the following API from your backend.

 curl --location 'https://cloud.yellow.ai/api/agents/settings/ticketUpdateEventSettings?bot=x1599195792555' \
--header 'x-auth-token: <token>' \
--header 'Content-Type: application/json' \
--data '{
    "chatAssignedBot": true
}'

This is a one-time process. After that, you'll start receiving **ticket-assigned-bot** events, which you can activate in the **Custom Event** section and [use it in your flows](https://docs.yellow.ai/docs/platform_concepts/studio/build/Flows/configureflow#13-trigger-flow-using-event).
