# List a sender profile mailbox tracking domains

`POST /api/sender-profiles/{sid}/mailboxes/{emailAccountSid}/tracking-domains`

## Request

- Base URL: `https://beta.getsales.io/unibox/v1`
- URL: `https://beta.getsales.io/unibox/v1/api/sender-profiles/{sid}/mailboxes/{emailAccountSid}/tracking-domains`
- Auth: HTTP bearer and API key in header `Team-SID`

The tracking domains a mailbox's email_tracking_domain_sid may point at: the live ones of the gtm-api workspace that holds the mailbox, by host name, each with gtm's DNS verdict. Only a verified one can be set (update_sender_profile_mailbox); creating a domain and checking its DNS happen in gtm-api. 403 gtm_scope_missing when the workspace's grant cannot read them.

- Operation `action`, response envelope `action`.
- Flags: read only.

## Path parameters

- `sid` string, required: Sender profile sid (ub_sp_…).
- `emailAccountSid` string, required: Which mailbox of the sender profile the verb acts on (em_ac_…); a sid the sender profile does not hold is a 404.
