# Link scenario step

![](/files/-MYuPaKuTTmPlFBqM1rh)

**Link scenario** step throws an object (or a few objects) to scenario.

{% hint style="info" %}
Hint: That step is a great way to use a scenario as a reusable micro-service
{% endhint %}

### Step settings:

#### Choose the object/objects to send

* **Current object**. The object from the scenario will be sent
* **Linked object**. Pick the field type of `link` with the ID of the object to send
* **Array of linked objects**. Pick the field type of `arrayLink` with the array of IDs of the objects to send.

#### Pick the link/arrayLink field (for the 2nd and 3rd options above)

The `link/arrayLink` may be stored among the object fields or in the context variables.

#### Pick the scenario to call

We'll throw the object (objects in case of arrayLink option) to that scenario.

{% hint style="info" %}

1. Note that the called scenario has to be **published** and **started**
2. You choose the scenario that processes the objects of the sent object's structure
   {% endhint %}

#### Set the sync/async mode

If you want, you may run the called scenario [synchronically](/scenarios/synchronic-scenarios-1.md). In the sync mode the step will wait until the linked scenario is finished.

#### Context parameters

If the called scenario has context variables, you'll be able to set the values of those parameters in the **Link scenario** step (using [templating system](/template-system/basics-of-template-system.md) and [JS-evaluation](/template-system/evaluating-as-js-expression.md))
