POST /v1/callbacks
- Scope
callbacks:write- Tier
- Tier 2 (reaches or unlocks real people)
- Data
- Personal data
- Idempotency
- Idempotency-Key: required
Tier 2. This operation can reach or unlock real people. It needs the scope callbacks:write and the account switch tier2_callback_write_enabled, which is off for every account unless DialerBee turns it on at your request. Until then it answers 403 tier_not_enabled. Daily cap: set before launch.
TIER 2. When due, the platform calls the lead. Needs the callbacks:write scope and the account switch tier2_callback_write_enabled.
Parameters
| Name | In | Type | Required | Description |

Idempotency-Key | header | string | yes | Your unique value for this logical operation (a UUID is fine). Scoped to your API client, kept 24 hours. (min length 1; max length 255) |
X-Correlation-ID | header | string | no | Your own trace value, logged with the request. Metadata only, never identity. (min length 1; max length 128) |
Request body
