Rules for in-text citation

Collation of Queries received from various research scholars about using the correct Referencing / citing using APA 7th edition referencing style

Question-1: 

One of the scholars asked me a question about citing the information received by email from (say) RBI via RTI which is not available on any website or cannot be accessed via a link.

As per APA Manual, a reference without a recoverable source cannot be included in the reference list because readers cannot retrieve the work. Nonrecoverable sources such as personal emails, classroom lectures, and intranet sources should be cited only in the text as personal communications.

For further information, refer to APA manual 7th Edition

a) Section 8.9 Personal Communication - Page 260

b) Section 9.37 No Source - Page 300

One of the scholars asked me a question about referencing a newspaper article without an author's name.

Newspaper article: Without Author

Extract from APA Manual, 7th edition

9.26 Online Periodicals With Missing Information

Many online periodicals (e.g., newspapers, blogs) publish articles without volume, issue, and/or page numbers or article numbers. Omit these elements from the reference if they are not present in the cited work. For example, for an online newspaper article or blog post, only the title of the periodical (i.e., of the newspaper or blog) may be present (see Chapter 10, Examples 16, 17, and 68).
