Creates a merchant secret to be used in legacy webhooks.
Set up a merchant secret for additional security. After creating a secret for the merchant account, each webhook includes a header containing a signature. You can use the signature to verify that all data received is authentic.
For a tutorial about configuring and using webhooks, see Configuring legacy webhooks in Guides.
NoteFor the current workflow, see the Register webhook URLs endpoint instead.
