That is definitely possible! Let’s take a look at how to go about accomplishing it 
.
There are two ways to achieve this. Using Webhooks, or using Subscenarios:
Using Webhooks
To make things easier for us, let’s start from the end, i.e. from the second scenario that you’ll want to trigger after the first scenario successfully ran.
First of all, you’ll need to create a webhook. That will be the starting module of the scenario that you want to trigger. In order to set everything up, use the “Copy address to clipboard” button.
​
​
Secondly, put an HTTP module “Make a request” at the end of the first scenario and paste the URL of the Webhook to the “URL” field:
​
And that’s it! 
Now, every time your scenario gets to the HTTP module, the module will send an HTTP request and trigger the custom webhook at the start of the second scenario 
Using Subscenarios
In the Make documentation, you will find interesting articles that explain in details what are subscenarios, and how to use them. Here
In Make, you can build a scenario and then call it from another scenario using a dedicated App called “Scenario”.
It allows you to call any other scenario, sending data, receiving data, waiting for the subscenario to finish execution or not, etc.
Using subscenarios is now the recommended way to call other scenarios.
