callerprovided

Callerprovided refers to data, parameters, or values that originate from the caller (the client or user) rather than the server or system. In software development, distinguishing caller-provided data from server-generated data helps clarify trust boundaries and processing requirements. A field or flag named callerProvided (often seen in APIs, JSON payloads, or configuration objects) indicates that the corresponding value is supplied by the client and should be treated as user input and thus potentially untrusted.

Usage often involves accompanying values that the server should not assume to be correct or safe. The server should validate, sanitize, and possibly reject data that does not meet required constraints. Examples include user-submitted form data, client-specified configuration options, or a policy or record provided by the caller. In some protocols, a boolean callerProvided may indicate whether a given value was supplied by the caller or generated during processing.

Security considerations are central to caller-provided data. Because such data can be malicious, all input should be validated, checked against a schema, normalized, and encoded as appropriate. Do not rely on the caller for correctness or safety; enforce least privilege, apply proper encoding, and maintain thorough logging for audit purposes.

Relation to data provenance: caller-provided data contrasts with server-generated or system-provided data, such as session identifiers, timestamps, and internal records. See also input validation, server-side processing, data provenance, and data sanitization.
