Hey! Thanks for your contribution!
If there is no particular reason to go with this client, I recommend to try our generated. Here is the method you are implementing https://github.com/aiven/go-client-codegen/blob/259be870943791d517994df16b18e601f0278ebe/handler/user/user.go#L107
It is experimental, but since it is generated it is more accurately than this one.

Hi @byashimov,

Thank you for your detailed feedback. In our project, we have used the Go package aiven-go-client. The suggested API is in the package go-client-codegen. Changing the Go package in our project might break our existing implementation.

If we could consider this PR, it would be greatly appreciated.

Please use *bool here to know if values was provided.

I have updated the Features type to map[string]any

Let's remove the test. It actually tests the struct and mocked value 🙏

Removed the test file.

1. Please use a pointer for Features
2. It might have more fields, as it has no strict schema
3. Intercom is required field

Updated the Features attribute type and marked the attributes as required based on the API reference in the documentation.

Thanks!

Hey. Thanks for the updates.
Please take a look at these:

1. there is no viewed_indicators field https://api.aiven.io/doc/#tag/Users/operation/UserInfo
2. should remove pointers from required field

I recommend to copy this struct https://github.com/aiven/go-client-codegen/blob/main/handler/user/user.go#L718
It was generated from the spec
