Importing and Exporting Custom Backends

Prerequisites

• Supplement the Swagger extended definitions for custom backends in the API file to import.
• Before importing a custom backend, ensure that there is sufficient custom backend quota.
• When importing a custom backend, the maximum size of a target API definition file is 3 MB.
• When exporting a custom backend, the maximum size of a target API definition file is 50 MB. If the size of the target API definition file exceeds 50 MB, the excess part will not be exported.

Importing Custom Backends

1. Log in to the ROMA Connect console. On the Instances page, click View Console next to a specific instance.
2. In the navigation pane on the left, choose API Connect > Custom Backends. On the Backends tab page, click Import above the backend list.
3. On the Import Backend page, configure backend import information.

   Table 1 Parameters for importing custom backends

   Parameter	Description
   Basic Definition Overwrite	Specifies whether to overwrite the existing backends when the imported backends conflict with the existing ones.
   Extended Definition Overwrite	Specifies whether to overwrite the existing extended information, such as the request throttling policy and access control policy, when there is a conflict between the imported custom backends and ROMA Connect. Enable: The existing extended information is overwritten with that defined in the imported file. Disable: The existing extended information is used, rather than that in the imported file.
   Swagger	Click Select and select a local YAML or JSON file that complies with Swagger specifications. After the file is imported, you can preview and modify the file online.
