# How to score and tag calls with post-call surveys

Post-call surveys let agents score, tag, and classify calls directly from the dial pad after a call ends. 
The caller hangs up, the agent hears the survey prompt, and pressing a digit triggers an action in Nimbata, such as applying a tag, assigning a rating, or recording a value.

||| Always assign the call flow you create to at least one tracking number for the survey to fire.

### Step 1. Go to Call Flows

* Go to [Tracking > Call Flows](https://app.nimbata.com/tracking/call-flows).
* Click **+ Create** to start a new call flow, or open an existing one you want to add a survey to.

### Step 2. Select From Scratch

* In the Create a New Call Flow menu, select **From Scratch**.

### Step 3. Add a Greeting

* Click the **+** plus sign in the call flow builder.
* Select **Greeting**.
* Choose **Text to Speech** or **Audio File** for your greeting message.

### Step 4. Add a Dial destination

* Click the **+** plus sign again.
* Select **Dial**.
* Choose your preferred destination number.

### Step 5. Add a Call Survey

* Click the **+** plus sign a third time.
* Select **Call Survey** from the menu.

### Step 6. Configure the survey message

* Choose **Audio File** to play a pre-recorded prompt, or **Text to Speech** to type your message.

🎉 Your call survey is set up. After each call ends, agents will hear the survey prompt and can respond by pressing a digit.

### How the survey is triggered

1. The survey starts automatically when the caller hangs up. 
2. The agent can also trigger it early by pressing ***** on the dial pad. 
3. Pressing ***** immediately ends the call and starts the survey.

### Automating tagging with call surveys

To assign tags, ratings, or values to the digits agents press, set up a workflow that listens for the **Digits Pressed by Destination** rule.
