Creating an event stream
Before you can subscribe to an event stream using the API you will first need to specify the set of events to be streamed using the Mambu UI. We strongly recommend reading our support article on the Streaming API for a walkthrough. Using the UI you will also create the body of each event notification using JSON, XML, or plain text and can make use of placeholders to include specific information such as client or account IDs, transactions amounts, or the values of custom fields.
Once the event streams have been created using the UI you will have a set of topics that you can subscribe to using the POST /subscriptions API by passing them in the event_types array.
