numbers.credential_limit_reached
This number already holds the maximum number of active SIP credentials.
numbers.credential_limit_reached means the number already holds as many active SIP credentials as it is allowed.
Several credentials per number is the intended design — one per device, each with its own password and lifecycle. Unbounded is a different matter: every credential is a potential live registration on an internet-facing registrar, so there is a cap.
Revoke a credential you no longer need. Revoked credentials do not count toward the cap, so this frees a slot immediately:
curl -X DELETE "https://api.sautikit.com/v1/numbers/{id}/sip-credentials/{cred_id}" \
-H "Authorization: Bearer $SAUTIKIT_API_KEY"To avoid hitting the limit unexpectedly, read the allowance before creating. The list response reports both figures:
curl "https://api.sautikit.com/v1/numbers/{id}/sip-credentials" \
-H "Authorization: Bearer $SAUTIKIT_API_KEY"{
"credentials": [ … ],
"active_count": 10,
"limit": 10
}If a mislaid password is what prompted a new credential, you probably do not need one: POST …/sip-credentials/{cred_id}/reveal returns an existing credential's password without disturbing the device using it.
