Retrieve a phone number
Returns one number of the workspace with its routing configuration (bound agent, IVR menu, channels). Deleted numbers return 404.
Idempotency. Read-only; safe to retry.
Access
- Required scope:
read(orwrite). - Rate limit: General API — per plan: 120 to 600 requests/min per workspace. See Rate limits.
- Plan: Available on every plan.
Authentication
Workspace API key: jl_ followed by 64 lowercase hex characters, created by the workspace owner in the
dashboard (Settings → API Keys) and sent as Authorization: Bearer jl_.... The plaintext is shown once,
at creation; Jelliu stores only a SHA-256 hash. A workspace can hold up to 25 active keys.
Operations restricted to admins or owners reject keys without the full scope with 403, and say so in
their description. No key, whatever its scope, can mint or revoke API keys or rotate a webhook secret —
that requires a signed-in owner session. A revoked key stops authenticating within about 10 seconds.
See Authentication.
Path parameters
The phone number’s id (not the E.164 number). Must be a UUID (400 otherwise).
Response
One number the workspace holds. channels says what it answers on; provider says where it lives. Field names are camelCase. Returned by every /api/phone-numbers endpoint.
