Creating the External System

All asynchronous operations require you to create an external system. This is so Oracle Hospitality OPERA Cloud knows for whom to process the request. The external system code is in the path of every Asynchronous API.

If you already have an external system created by the OPERA environment owner, ask them to check whether step 4–d is complete. If complete, you can use this for the Asynchronous APIs.

Only the (Customer) OPERA environment owner can create an external system. They should follow this process:

1. Verify a chain-level user has the below tasks assigned. To assign these tasks, follow the steps in the Assigning Tasks to a Role topic in the OPERA Cloud User Guide.
   1. Navigate to Interfaces Admin, Property Interfaces and External Systems.
   2. Select New/Edit External Systems.
2. Log in at the Hub level (not the property level).
3. From the Administration menu, select Interfaces, select Business Events, and then select External Systems.
4. Click New and enter the following details:
   1. Code: Enter a code for the external system.
   2. Description: Enter a name of the external system.
   3. Sequence: Specify sequence in which the external system will display in the External Systems list.
   4. For each property in the chain, enter or select the Property and click Active to activate it.
5. Click Save.
   Make sure you remember the external system code you created.
6. Communicate to the integrator the external system code created at step 4.
   If customers have any challenges with creating the external system, they should either contact Oracle Customer Support at the Customer Support Portal (in case of a technical error) or contact Oracle Hospitality Consulting Services if additional help is needed.
