Full replace: the supplied `data` object entirely overwrites the stored payload — to change one key, read the current payload, modify it, and send the whole object back. An empty object `{}` clears the payload. Requests are limited to 64 KiB. ## OpenAPI ````yaml /api-reference/rest-api-v4.yaml put /remote-configurations/{config_id}/payload openapi: 3.0.3 info: title: Qonversion REST API v4 version: '4.0' description: >- Qonversion REST API v4 follows REST standards.
