# Connection with a trigger

## The tr**igger field**

This field specifies the trigger for transitioning to another block.

<div data-with-frame="true"><figure><img src="/files/Dh5JeTdxYwxloIBqBiHn" alt="" width="563"><figcaption></figcaption></figure></div>

{% hint style="success" %}
The transition trigger can be set by a keyword (callback). You can read more about [Triggers and match type **here**](/chatbot/builder/setting/trigger/type.md).
{% endhint %}

{% hint style="info" %}
If the **Trigger** field in the connection is left empty, the transition will occur on any word or phrase from the user.
{% endhint %}

### Connection triggers

An connection with a trigger is a connection that activates a transition only if a certain trigger is met.

<div data-with-frame="true"><figure><img src="/files/EcStN9l6iR499rPqM6KI" alt="" width="563"><figcaption></figcaption></figure></div>

The connections's triggers can be set:

* By a certain word (callback) — specified in the **Trigger** field.\
  For example, when the **NO** button is pressed, the bot replies with **"Have a nice day!"**. You can read more about this **here**.\
  At the same time, words (callbacks) that the arrow should ignore can be specified (mostly used when the **Trigger** field is empty).
* By analyzing variable values — specified in the **Variable** field. You can read more about this **here**.

Additionally, it is possible to create keyboard (reply) buttons. To do this, simply enter the button text in the **Trigger** field and enable the **Display as button** toggle.

You can also specify a check for user input in the connection trigger using regular expressions:

<div data-with-frame="true"><figure><img src="/files/P3YAXNTsKMs5kYWE8pwo" alt=""><figcaption></figcaption></figure></div>

You can also use a variable for comparison:

<div data-with-frame="true"><figure><img src="/files/IOI9gD3XClCrnWypKNY3" alt=""><figcaption></figcaption></figure></div>

<mark style="color:$warning;">**However, according to the syntax rules, you cannot specify multiple comparison triggers  for the same variable in a single trigger.**</mark>

<div data-with-frame="true"><figure><img src="/files/b8pqzUAfOosrhesfSLqa" alt=""><figcaption></figcaption></figure></div>

If you need to check multiple values in a condition, use the operators **and (&&)**, **or (||)**, and others.

{% hint style="info" %}
[You can read more about variable comparison in the article of the same name.](/chatbot/functions/variables.md)
{% endhint %}

### Match type

By default, **"Fuzzy match"** is selected.&#x20;

In MaviBot, there are five types of trigger matching:

1. Fuzzy match;\
   The condition will be checked for partial matches with the user’s input. This means that if the user enters a word or phrase with mistakes or different endings, the condition will still trigger.
2. Keyword match;\
   If this option is selected, the transition will trigger if the user’s response contains at least one keyword from the "Trigger" field.
3. RegEx match;\
   The condition checks the user’s response against the regular expression you specify.
4. Exact match;\
   This condition checks the word or phrase for an exact match, without errors or modifications.
5. Semantic search.\
   This is the smart search for semantic in a client message with AI.

<div data-with-frame="true"><figure><img src="/files/wLr70mHWH1yKR8jCyJoC" alt="" width="563"><figcaption></figcaption></figure></div>

{% hint style="info" %}
For example: validating phone number format, email, input of digits only, etc. You can read more about [regular expressions **here**.](/chatbot/functions/regex.md)
{% endhint %}

### **Advanced connection settings**

To open the Advanced settings, click on **"Advanced settings"** below the **Match type** field, as shown in the image below.

<div data-with-frame="true"><figure><img src="/files/6kC7cNlB1BSdeboRFOFo" alt="" width="563"><figcaption></figcaption></figure></div>

### Ignore triggers

Enter the "negative words" here — words or phrases that the bot should not respond to when checking the trigger.

<div data-with-frame="true"><figure><img src="/files/WWhha9Lpz09x73qdLU3s" alt="" width="563"><figcaption></figcaption></figure></div>

### Variable

The variable for comparison works together with the trigger or the "Ignore triggers" stroke. That is, both the trigger and the trigger in the variable must be met.

<div data-with-frame="true"><figure><img src="/files/nz4buIsQ54ASgfUAaLOw" alt="" width="563"><figcaption></figcaption></figure></div>

If you specify only the variable name in the comparison variable field, without an expression, the condition will be compared with the variable’s value instead of the user’s input.

{% hint style="warning" %}
You should specify it without `#{}`, using only the variable name.
{% endhint %}

In the example shown in the image below, the transition will occur if the value of the "AGE"variable:

<div data-with-frame="true"><figure><img src="/files/PE01h8eOXwvwzJI8lGH8" alt=""><figcaption></figcaption></figure></div>

The example created four blocks:

1. A **Start block** for entering the bot: this block asks the client's age.
2. A **second block** with a connection that collects the client's data into a variable (this variable will help route the client through the funnel).
3. **Two blocks** connected to the previous block:
   * If the client is **over 18**, the message "The second message" will be sent.
   * If the client is **under 18**, the message "I'm sorry, you can't text to the bot" will be sent.

<div data-with-frame="true"><figure><img src="/files/gjxGE8ZQdDMHeyAzCjLf" alt="" width="563"><figcaption></figcaption></figure></div>

{% hint style="success" %}
Learn more about data collection connections in the article "[Connection with a data collection](/chatbot/builder/connections/data.md)".
{% endhint %}

Step 1. Create four blocks.

<figure><img src="/files/4JFFo5hZkr5asQjUIYzo" alt="" width="375"><figcaption></figcaption></figure>

Step 2. Connect the "Start" block to the second "Chat" block.

<div data-with-frame="true"><figure><img src="/files/PZCQVIL0dhhXH9DSI32N" alt="" width="563"><figcaption></figcaption></figure></div>

Step 3. Go to the connection settings and activate the "Data collection" checkbox.

<div data-with-frame="true"><figure><img src="/files/Cc3r4m2DhXxX8GaHLr3v" alt="" width="563"><figcaption></figcaption></figure></div>

Step 4. Enter the variable in the "Input data" field and save the connection settings.

<figure><img src="/files/3AiFq2FNL7zAZ3kA61PU" alt="" width="563"><figcaption></figcaption></figure>

Step 5. Connect the second block to the remaining blocks.

<div data-with-frame="true"><figure><img src="/files/o7EeivqAyYrRjKLsrp9u" alt="" width="563"><figcaption></figcaption></figure></div>

Step 6. Go to the connection settings and enter 'age ≥ 18' in the "Variable" field.

<div data-with-frame="true"><figure><img src="/files/nH6Ir4Lyj150vdrmCDqj" alt=""><figcaption></figcaption></figure></div>

Step 7. Set the timer to "0 seconds" on the same connector.

<div data-with-frame="true"><figure><img src="/files/OFWn00iUicCnYUIerR7z" alt=""><figcaption></figcaption></figure></div>

Step 8. Set the value to "age < 18", and configure the connector similarly to the previous one.

<div data-with-frame="true"><figure><img src="/files/GxMHSAUXARppZcAgnuSg" alt=""><figcaption></figcaption></figure></div>

{% hint style="success" %}
Done! You have now learned how to create a bot that checks a client's age and sends a message based on their age!
{% endhint %}

### Priority

By default, the priority value is set to 10. The higher the priority of the condition, the earlier it will be checked.

<div data-with-frame="true"><figure><img src="/files/WJkg8dOjUcA40oZc0dz2" alt="" width="563"><figcaption></figcaption></figure></div>

### Callback-Only trigger

If this toggle is activated, the client will only proceed to the next block connected by the arrow if a callback is received by the system.
