CustomerIOSharp 1.0.0.26

Customer.io API C# implementation

Implementation of Customer.io's write-only API for .NET.

Installation

Using Nuget:

Install-Package CustomerIOSharp

Usage

We recommend you implement the ICustomerFactory interface yourself. Here is a suggested implementation used in one of my projects:

    public class CustomerFactory : ICustomerFactory
    {
        public ICustomerDetails GetCustomerDetails()
        {
            var user = MembershipHelper.GetCurrentUser();
            return user == null 
                ? null 
                : user.AsCustomer();
        }

        public string GetCustomerId()
        {
            var user = MembershipHelper.GetCurrentUser();
            return user == null
                ? null
                : user.UserId.ToString();
        }
    }

Then instantiate CustomerIo and call IdentifyAsync():

var customerIo = new CustomerIo(
    "siteid", 
    "apikey", 
    new CustomerFactory());
await customerIo.IdentifyAsync();

You should most likely only call IdentifyAsync() whenever the user logs in or is changed.

If you do not want to implement ICustomerFactory, you can simply provide the required details to each call:

await customerIo.IdentifyAsync(User.AsCustomer());

Whatever you do, you will have to provide customer data implementing ICustomerDetails. It has only two required properties, but any properties you supply in your implementation will be forwarded to customer.io:

public class Customer : ICustomerDetails 
{
    // these two fields are required:
    public string Id { get; set; }
    public string Email { get; set; }
    // these are my custom fields:
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

Custom events

Track a custom event by calling TrackEvent(). It takes an event name as the first parameter, the second parameter is any serializable object. Note that it automatically posts using the correct customer (using ICustomerFactory), but you can also supply your own.

await customerIo.TrackEventAsync("signup", new {
	UserGroup = "trial",
	Referrer = "email campaign"
});

// this event has no data and uses a different customer
await customerIo.TrackEventAsync("signup", customerId: "foo");

Note that these two variables will be camelcased before being sent to customer.io, so userGroup and referrer will be available in your transactional campaigns.
