Absolutely! Each recipe can work with as many unique apps as your use case requires. As you build out your recipe, just select the specific app you would like to integrate, and select the method you want. For example, you can create a single recipe that executes every time there is a new blog post on your Wordpress blog to post a status on Facebook, Twitter and LinkedIn.
If the application, trigger or action you require is not supported, do leave a post in our forums!
However, if you would like to connect 2 instances of the same app in a single recipe, you may use secondary connectors if your app allows it. If the app you need does not have a secondary connector, you can use callable recipes to help you with that. Find out more here.
