The first step is to install Instasent packages from N8n.
​
We must go into N8n and click on the three dots in the bottom left corner

After that, we click on "settings", then "Community nodes" and finally "Install a community node":

Now we have to wait a few minutes to install.
​
Once we have our packages installed, we can go back to Instasent, to the data sources section. and install N8n:

Now we must fill in some basci information, we may add a tag to these contacts coming from N8n and the we click on finish.

Then we will see some credentials that will be useful later in the process:

Now it's time to go back to N8n and start a new Workflow.
For this example, we’ll use an “On form submission” trigger.
In our case, we’re only going to add two fields:

Name and Phone number:

After this, we can do a little test to try our form from here:

We’ll see that a contact is created with the information we just entered in the form.

Now let’s go back to the N8n home page and add another action called: Instasent Data Source.

Here we’ll see three options: Create or update a contact, Delete contact, or Create an event.

In this case, we’ll use Create or update a contact, but you might choose a different action depending on your use case — the logic works the same way.

Once we click on Create or update a contact, we’ll have the option to map the data:

You’ll need to drag the fields from the left into the User ID section, one by one.
In this first case, we’ll map the Full name:

After this, we must configure the credentials to connect Instasent by clicking here:

And here we will have to configure the credentials with the information that Instasent gave us when we connect with N8n through Instasent.

Once we have this information, we can save the workflow.

Once we have all the values mapped, we can check "Instant"

Once everything is seted up, we can click on Test step and verify that everything is correct.

Now we go back to Instasent, finalize the integration with N8n and verify that the text contact is created successfully:

No we can go back to N8n and save the new Workflow, activate it and lastly get the production URL.

With this URL, we can start receiving real contacts.
​
We recommend testing in production to check that everything is working properly.
