A custom origin is a subdomain that is configured for a specific customer and looks like: abc.pubnubapi.com
Using a custom origin allows PubNub to route traffic per customer when a point of presence is not performing well or becomes unavailable. It also allows for custom configurations that may be required by a customer for a specific use case or region.
If you do not already have a custom origin you can request by filing a support ticket with PubNub Support, using the subject, Request Custom Origin. Be sure to provide the following to support in the ticket message body:
- Three choices for your subdomain in order of preference (12 characters or less)
- The PubNub SDKs you currently use in your applications: SDK language/name and version.
- Do you have customers or devices in China?
PubNub Support will provide you with confirmation on your custom origin name and sample code to configure for each of the PubNub SDKs/versions you are using in your applications.
NOTE: a paid plan is required to receive a custom origin.
