The controller first validates the charge state against client, program, charge id, and optional session id, then returns the common Flutterwave v4 charge response payload. Public checkout polls this endpoint after redirect, OTP, or 3DS flows. ## OpenAPI ````yaml get /frontend/flutterwave-v4/campaign-charge/{client_id}/{program_id}/{charge_id}/{session_id} openapi: 3.0.0 info: title: Gratona API description: >- REST API for the Gratona fundraising platform, including donor, donation, sponsorship, program, event, and integration workflows.
