How can I add contacts to a list using API importing?

When using the API to import contacts in Sendx, it's important to understand that contacts cannot be directly imported into a list. Instead, they need to be added to a tag. Don't worry, though!

We will guide you through the process of creating a tag and importing contacts using the API.

Step 1: Creating a Tag

Before importing contacts, let's start by creating a tag where the contacts will be added.

Step 2: Importing Contacts Using API

Now that you have your tag ready, let's move on to importing contacts using the  Rest API. 

Step 3: Creating a List

Next, it's time to create a new List or choose the name of an existing list that you want to add all the contacts from the tag.

Step 4: Create an Automation 

To streamline the process, we can create an automation that will automatically handle the task of adding contacts from the tag to the chosen list. Here's how to do it:


  • Tag Added 
  • Tag name 


  • Confirmed to a List  
  • List name

Submit the automation. We hope this guide has been helpful to you. If you have any additional questions, please let us know.
