Is certificate pinning required?
What is SSL pinning. Applications are configured to trust a select few certificates or certificate authority (CA), instead of the default behaviour: to trust all CAs that are pre-configured on the device/ machine. SSL pinning is not required.
What is the difference between certificate pinning and stapling?
Stapling – The process of appending a digitally signed OCSP response to a certificate. It reduces overall OCSP traffic sent to a CA. Pinning – A security mechanism used by some web sites to prevent web site impersonation. Web sites provide clients with a list of public key hashes.
What’s the difference between certificate pinning and public key pinning?
Public key pinning is more flexible but a little trickier due to the extra steps necessary to extract the public key from a certificate. As with a certificate, the program checks the extracted public key with its embedded copy of the public key. There are two downsides two public key pinning.

Is there a difference between stapling and pinning?
One exception is revocation and it is discussed below in Pinning Gaps. It is also worth mention that Pinning is not Stapling. Stapling sends both the certificate and OCSP responder information in the same request to avoid the additional fetches the client should perform during path validations.
