Overview

Bulk update client settings for multiple clients in a single operation. Supports partial success - individual clients can fail while others succeed.

Currently Supported Field

This endpoint currently supports updating only the opt_out_transactional_sms field. Any request containing other fields will be rejected with a validation error.

Field Requirements

• opt_out_transactional_sms must be an explicit boolean value (true or false)
• null values are not allowed
• Missing the field will cause validation failure

Limits

• Maximum 1000 clients per request
• Duplicate client UIDs are not allowed

Authentication

Available for Staff Tokens only.

Client tokens should use the single update endpoint /v3/clients/client_settings/{client_uid} instead.

Response Behavior

• Returns HTTP 200 with an array of results (one per client)
• Each result includes a success boolean and either data (on success) or errors (on failure)
• Individual client failures (e.g., not found) do not prevent other clients from being updated
