24001: Invalid parameter

A specific query parameter, path parameter, or header value is invalid. Unlike a general validation error (24000), this indicates a single parameter failed validation rather than the request body.

• A query parameter value is outside the allowed range (for example, pageSize greater than 100 or less than 1).
• The labels query parameter does not follow the expected format (key1:value1,key2:value2).
• A path parameter is not a valid Twilio Time-based ID (TTID). Audience IDs start with aud_, snapshot IDs with snap_, and operation IDs with op_.
• The order parameter is not one of the accepted values (asc or desc).

• Check the errors[] array in the response — the pointer field uses the #/query/<name> or #/path/<name> prefix to identify which parameter failed.
• For pagination, use pageSize between 1 and 100 (default is 20).
• For label filtering, format labels as key1:value1,key2:value2 with no spaces around separators.
• For resource IDs, use the exact TTID returned by the create or list response (for example, aud_audience_01h9d8r0vte3hz8tykdj329t7r).
