Interface RequestHeaderProvider

All Known Implementing Classes:
SppApiTokenHeaderProvider

public interface RequestHeaderProvider
Interface for providing dynamic request headers (e.g., Auth tokens, nonces).

Implementation Note: Implementations must generate fresh values (e.g., new nonces, current timestamps) on every call. The underlying HttpClient may reuse request objects during automatic retries. Do not cache values within the provider, as the SDK cannot guarantee that this method will be re-invoked for every individual transmission attempt.
