Tone docs
API referenceCampaigns

Fetch a single campaign

Includes the snapshot taken at launch — the agent, the number and the sender classification the run actually used — which is evidence, not a live read of what those objects say today.

Requires the read scope. A key with less gets 403 insufficient_scope.

GET
/v1/campaigns/{id}

Authorization

AuthorizationBearer <token>

Authorization: Bearer tone_live_… or tone_test_…. The prefix IS the environment: a test key reaches only the sandbox, and no request field bridges the two.

In: header

Streams CSV rather than JSON, for the whole list rather than a page.

Apply the pre-flight exclusions and start dialling (requires Idempotency-Key)

🔴 Idempotency-Key is REQUIRED — without it this returns 400. Launching twice would dial the whole list twice, which is exactly the complaint pattern TCCCPR punishes. Refused if the agent is still a draft, if the number routes to your own stack, or if any pre-flight check blocks. Scrubbing runs here and MUST succeed: a scrubber outage fails the launch rather than passing an unscrubbed list.
