Registering an authorized app in API Gateway

To access the REST services through an external application such as Postman, you must register an app in API Gateway. After the app is registered, you can download the credentials for the service account.

You can use this app and the corresponding user credentials to test the LN REST API services, for example, using Postman.

To register an app for Infor LN:

In ION API, create an authorized app for Infor LN. For details see “Registering the client application” in the Infor API Gateway Administration Guide.
Points of attention for this LN-specific app:
- In the Type field, specify Backend Service.
- Ensure Issue Refresh Tokens is selected.
Click Save.
Download the credentials for the service account:
1. Click Download Credentials.
2. Ensure Create Service Account is selected.
3. Complete one of these steps:
  - Leave the Full name field blank. Consequently, the LN user svc_ln is used as service account to send requests to LN. This is useful, for example, in a scenario where you use 20 similar machines that must log on using the same service account.
    Note: In this scenario, each machine contains the credentials of the svc_ln service user. All requests sent by any machine are logged as sent by svc_ln. Consequently, no traceability and accountability can be performed for the different machines. However, while using a single service account, each machine can be assigned a unique identity, allowing for traceability and accountability for the different machines.
  - In the Full name field, specify an IFS user name. Consequently, the corresponding LN user is used as service account to send requests to LN. You can repeat this download procedure to download credentials for multiple IFS users. This can be useful, for example, if each user has an own handheld device that must connect to LN using the user’s credentials.
  Note: In this scenario, each handheld device contains the credentials of a different IFS user; that is, a device contains the credentials of its owner. All requests sent to LN through a particular handheld device are logged as sent by the LN user account of the device's owner. Consequently, traceability and accountability can be performed for the different devices/owners.
In the Scopes field, select Infor LN.
