Improve the API fields data type information in the API documentation

[ymgupta]

Summary

The Things Stack users are often confused with API field data types i.e., in the documentation API field type type: bytes does not imply base64. Also, the type of API field interpreted should depends on the actual message. For example, the frm_payload of the ApplicationDownlink is read as a base64 type, whereas the dev_eui field of the EndDeviceIdentifiers is read as hex.

Why do we need this ?

To help users in distinguishing between different data types of API fields.

What is already there? What do you see now?

We need to update our tooling in order to deal with this inconsistency. I will pick this up.

I'll pick this up as part of the API documentation item that I'm working on.
