List a channel's available senders

GET
/api/v3/channels/{channel}/senders
curl --request GET \
--url 'https://api.tryletterhead.com/api/v3/channels/example/senders?api=true' \
--header 'Authorization: Bearer <token>'

List the sender identities available on this channel — the set that the composer’s “Send from” picker loads. Each sender carries every channel it’s assigned to (not just this one), so you can read its isDefault flag for any of its other channels too.

status (verified/unverified roster status) is left blank on this endpoint — it’s only computed on the company-wide sender list (GET /api/v3/senders).

v3 endpoints expect a company API key.
