With Team and access enforcement enabled, the assignee must be active and have sms_inbox_reply or sms_inbox_manage. Does not change the line owner or its visibility. Conversations and available lines respect line visibility: restricted lines require assignment to the viewer or sms_inbox_manage/group_all. Requires permission: one of sms_inbox_manage; plus one of beta_features. ## OpenAPI ````yaml post /admin/sms_inbox/conversations/{conversation_id}/assign 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.
