Question API Onyx 17.8.x search on alternate field

[gody]

Hello,

I see the API was updated with the last version of onyx with the support of Json but no new functions...

I check all methodes and I don't found how to do a search based on an alternate field.
I would like to get the customer information based on the External ID (Not the ID).

API : Build, Collaborate & Integrate APIs | SwaggerHub​

In exemple ISPConfig allow extented query on other field:

• Classic search : curl -X POST -H "Content-Type: application/json" -H "Cache-Control: no-cache" -d '{"session_id": "ID_SESSION", "client_id":"XXXXX"}' "https://URL_ISP:8080/remote/json.php?client_get"

• Extended search : curl -X POST -H "Content-Type: application/json" -H "Cache-Control: no-cache" -d '{"session_id": "ID_SESSION", "client_id":{"customer_no":"XXXXX"}}' "https://URL_ISP:8080/remote/json.php?client_get"

Any possibility or suggestion with Onyx ?

Thanks
Gody
