Hello Readers !!

Today we are going to discuss the IAP in the Unity3D.

We can do IAP by number of plugins. There are variety of plugins available in the market which we can use for the IAP. But almost all of the plugins are paid.

Here are the links for the plugins:-

https://www.assetstore.unity3d.com/en/#!/content/12343

https://www.assetstore.unity3d.com/en/#!/content/28679

But all these plugins have limitations. We can use these plugins only for some platforms. If we want to create IAP for all the platforms which Unity provides then we need to do something different from this.

For this only, Unity provides a new feature that is called Unity IAP, which comes under the Unity services.

Adding the unity services in the code is very simple and straight forward. You just need to click on the "On" button under services section.

This will import all the required plugins in your game. After that, you need to write down a small code.

You need to add your own Product ID, Rest of the code will be same for you.

Try this and have fun.

Till then keep coding.
