Custom Proxy Requirements
- Clients are welcome to use their own reverse proxy solution. Most firewall appliances can provide this functionality.
- Our recommended best practice is a network layer proxy secured with TLS client certificates. Be careful if you're using a layer 7 proxy or API management solution since it may block some of the requests and introduce additional latency.
- If you're using your own reverse proxy, ensure that your proxy does not attempt to validate the XML since some responses passing through the system may not conform to verifiable standards.
- Refer to Salesforce IP addresses and Domains To Allow for details.
