PayPal: Get a sandbox access token

See more PayPal Examples

Exchange a sandbox REST app client ID and secret for a bearer token on a merchant-controlled backoffice workstation. PayPal supplies its lifetime in seconds. Store the token in a protected credential store; the companion expiry example reads only timing metadata.
