Auto-Provision a Number

Skip the browse-and-pick flow. Auto-provision picks the first available number matching your criteria:

$
curl -X POST "https://api.voicebip.com/v1/numbers/auto" \
>
  -H "Authorization: Bearer pk_live_xxx" \
>
  -H "Content-Type: application/json" \
>
  -d '{
>
    "agent_id": "agt_XXXX_xxxxxxxxxxxx",
>
    "type": "mobile_virtual",
>
    "country_code": "NG",
>
    "channels": ["voice"]
>
  }'

Returns the same 201 response as manual provisioning.

List Provisioned Numbers

Retrieve all numbers your workspace currently owns:

$
curl "https://api.voicebip.com/v1/numbers?page_size=20" \
>
  -H "Authorization: Bearer pk_live_xxx"

Filter by agent_id to find numbers assigned to a specific agent:

$
curl "https://api.voicebip.com/v1/numbers?agent_id=agt_XXXX_xxxxxxxxxxxx" \
>
  -H "Authorization: Bearer pk_live_xxx"

Get a Single Number

$
curl "https://api.voicebip.com/v1/numbers/num_abc123" \
>
  -H "Authorization: Bearer pk_live_xxx"

Release a Number

Released numbers enter a 30-day quarantine period (NCC compliance) before returning to the available pool.

$
curl -X DELETE "https://api.voicebip.com/v1/numbers/num_abc123" \
>
  -H "Authorization: Bearer pk_live_xxx"

Reclaim a Quarantined Number

If you released a number within the last 30 days, you can reclaim it before it returns to the shared pool:

$
curl -X POST https://api.voicebip.com/v1/numbers/num_xxx/reclaim \
>
  -H "Authorization: Bearer pk_live_xxx" \
>
  -H "Content-Type: application/json" \
>
  -d '{"agent_id": "agt_xxx"}'

The number must still be in quarantine and must have been owned by your workspace. Channels default to ["voice"] if not specified.

MNO Coverage

Every Nigerian mobile virtual number is routed through the appropriate MNO:

Outbound calls and SMS are routed to the correct MNO automatically with failover: MTN -> Glo -> Airtel -> 9mobile.

Channel Types

Each number is assigned a channel at provisioning time:

• voice — Receives inbound calls, makes outbound calls
• sms — Sends and receives SMS messages
• whatsapp — WhatsApp messaging (Phase 2)

A single number cannot serve multiple channels simultaneously. Assign separate numbers to the same agent for multi-channel presence.
