constructionPreprocess

Preprocess is called prior to /construction/payloads to construct a request for any metadata that is needed for transaction construction given (i.e. account nonce).

The options object returned from this endpoint will be sent to the /construction/metadata endpoint UNMODIFIED by the caller (in an offline execution environment). If your Construction API implementation has configuration options, they MUST be specified in the /construction/preprocess request (in the metadata field).
