Contacts are validated as E.164 and de-duplicated within the batch; the call list is immutable after creation. Campaigns are created as `draft` unless `status` says otherwise — activate separately to start dialing. ## OpenAPI ````yaml https://api.pathors.com/openapi.json post /v1/campaigns openapi: 3.1.0 info: title: Pathors API description: >- Public developer API for the Pathors platform.
