-Need to explain how to connect their app: https://dashboard.request.network/settings/apps
+Request API is an abstraction over the Request Network for easy, but centralised, access. It's the fastest way to get started and build integrations.
+
 ## Pros
-TODO
+* Simple REST API, familiar for classic web developers
+* No key management
+* Faster response time
+* Notifications on new request and received payments
+* Send requests to other API users based on their email, instead of their ETH address.
+* Easy to build applications on top of Request (see [here](./3-api-apps))
+* Easy choice between fully public data or encrypted data on the network 
 
 ## Cons
-TODO
-* Your users have to create a Request account the first time they use the feature
+* centralised 
+* users need a Request account to connect
+* encryption is not end-to-end (see [here](./4-api-encryption.md))
