Should we encrypt all REST API calls from a mobile device?

I have a mobile application and the backend is hosted on a cloud provider. I would like to ask for feedback on encrypting all REST API calls that will be used to communicate with the server, if we should or we shouldn’t do it.

Adding details:

for example instead of having a proper rest object

{    "name" : "username",    "info" : "profile" } 

make it similar to this:

{    "encryptedData" : "Mq6rTVdPP1YMlE9AxhnryIRX+JA9MfIXv" } 

and after decryption it becomes the model and the flow carries on, of course the response is also expected to be encrypted in a similar fashion.
