Value Type of Identification in API Response

[Su Ho]

Issue

Based on the document from jsonapi.org:

Every resource object MUST contain an id member and a type member. The values of the id and type members MUST be strings.

Here is the link: https://jsonapi.org/format/#document-resource-object-identification

Currently, the value type of id is Int

Expected

The value type of id should be `String

Steps to reproduce

1. Login with API {{base_url}}/api/v1/oauth/token
2. Check the response
