A/B Testing - TurnCall

Split traffic between agent versions to test performance. Routing is deterministic by caller number (SHA256 hash) — the same caller always gets the same variant.

Set Weights

Weights must sum to 100:

curl -X PUT http://localhost:8090/v1/phone-numbers/PHONE_ID/routing \
  -H "Authorization: Bearer tc_xxx" \
  -H "Content-Type: application/json" \
  -d '{
    "weights": [
      {"agent_id": "agent-v1-uuid", "weight": 80},
      {"agent_id": "agent-v2-uuid", "weight": 20}
    ]
  }'

Check Routing

curl http://localhost:8090/v1/phone-numbers/PHONE_ID/routing \
  -H "Authorization: Bearer tc_xxx"

Response:

{"mode": "weighted", "weights": [...]}

Clear Test

Revert to single-agent routing:

curl -X DELETE http://localhost:8090/v1/phone-numbers/PHONE_ID/routing \
  -H "Authorization: Bearer tc_xxx"

How It Works

Inbound call arrives on a phone number with weighted routing
TurnCall hashes the caller’s phone number (SHA256)
The hash determines which agent variant handles the call
Same caller always gets the same variant (deterministic)
