The batch must currently be in `undone` status. Requires permission: `duplicates_manage` (also satisfied by `donors_manage`). ## OpenAPI ````yaml post /admin/duplicates/merge/batches/{batch_id}/restore 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.
