# Conversion Tracking
Storyly increases user conversion but you do not need to take our word for granted. Here we explain how to create a conversion action to track customer actions on your application so that you can measure the performance of your stories. Conversion can be any valuable customer activity on your application, such as subscriptions, purchases and form submissions.
Whenever there is a valuable customer activity you can send it by making a post request to below endpoint
https://trk.storyly.io/traffic/<STORYLY_INSTANCE_TOKEN>
with the below json body. Note that the detail can be any property of the conversion event; such as the value of a purchase, subscription period, etc.
{
"custom_parameter": {<VALUE_USED_DURING_INITIALIZATION>},
"payload": {
"event_type": "Conversion",
"detail": {
...
...
}
}
}
WARNING
You have to give same value for custom parameter during SDK initialization and conversion tracking.
WARNING
Please make sure you are using the correct token.
