I am using REST API to interact with SpiceDB Services, To upload a schema using write-schema API we provide the SchemText value as String inside API Request Body, something as below{ "schemaText": "definition secure_group {}\n\ndefinition resource {\n\trelation creator: secure_group\n\trelation viewer: secure_group\n\tpermission create = creator\n\tpermission view = viewer + creator\n}" }
