SSL Termination
Upload a cert, then reference it in a forwarding rule:
POST /v1/certificates
{ "name": "my-cert", "private_key": "...", "certificate": "...", "certificate_chain": "..." }
# In forwarding rule:
{ "entry_port": 443, "entry_protocol": "https",
"target_port": 3000, "target_protocol": "http",
"certificate_id": "cert_xyz" }Pricing
Load balancers are included free. You pay only for outbound bandwidth (5 TB/mo free).
