post_post_parser.add_argument(
    'title',
    type=str,
    required=True,
    help="Title is required"
)
post_post_parser.add_argument(
    'text',
    type=str,
    required=True,
    help="Body text is required"
)
post_post_parser.add_argument(
    'tags',
    type=str,
    action='append'
)

Next, the PostApi class will need a post method to handle incoming requests. The post method will use the given values for the title and body text. Also, if the tags key exists, then add the tags to the post, which creates new tags ...
