Getting Geofences

nasnew, do you use remote api or javascript api?
remote api
You can get all geofences from all resources using such request:

https://hst-api.wialon.com/wialon/ajax.html?svc=core/search_items&params={"spec":{"itemsType":"avl_resource","propName":"zones_library","propType":"propitemname","propValueMask":"!","sortType":"sys_name"},"force":1,"flags":0x00001001,"from":0,"to":0}&sid=sid

If you need to get geofences only under certain resources you can use such request:

https://hst-api.wialon.com/wialon/ajax.html?svc=core/search_items&params={"spec":{"itemsType":"avl_resource","propName":"zones_library,sys_id","propType":"propitemname","propValueMask":"!,your_res1_id,your_res2_id","sortType":"sys_name"},"force":1,"flags":0x00001001,"from":0,"to":0}&sid=sid

You can get all geofence groups including their geofences ids  for certain resource using such request:

https://hst-api.wialon.com/wialon/ajax.html?svc=core/search_items&params={"spec":{"itemsType":"avl_resource","propName":"zone_groups,sys_id","propType":"propitemname","propValueMask":"!,your_res_id","sortType":"sys_name"},"force":1,"flags":0x00100001,"from":0,"to":0}&sid=sid

To create/update geofence group and add geofences to it you can use such request:

https://hst-api.wialon.com/wialon/ajax.html?svc=resource/update_zones_group&params={"itemId":<your_res_id>, "id":<id_of_group_if_exists>,
                      "callMode":<create/update>,
                      "n":GROUP_NAME,
                      "d":DESCRIPTION,
                      "zns":[<zone_id1,zone_id2,zone_id3>],
                      "f":0}&sid=sid

Hi,

I have system that fetch data from wialon and we use to have report in wialon generated and then fetched them with API calls to our custom app. It was working fine untill we have change in user. It appears wialon has complex structure in index and it got changed with user.

Any one please bail out as we are stuck as all api calls are falling deaf and we are not getting desired data.

Please have a look at attached file where we are getting unit name instead geofence and which is havoc in our existing system.

Regards,
Shah

Thanks for your reply,

I have checked my credentials.
it is fine still getting unit name instead of geofence name.
Please help me out..
I have attached screenshot for reference.

Hi, Looking in to your attached screen shot, it seems like you have selected vehicles rather than Geofences when you create your Geofence report template.  please see the attached to better understand what I am referring to.

In addition when you create your user please make sure you have assigned your user with the privilege to create, read and update Geofence resource. (please check the second attachment ) or the user has the privilege to have access to the resource consisting the Geofences.

If all are ok i think it is better to check the API request you are making.

shah007, do You need only geofences in report result? As I wrote just uncheck units in report template.

shah007, I've created copy of Your report template (final data) and unchecked all units in Geofences table and got only geofences in resulting report. Try it.

For those trying to use it but failing in Dec 2021, there is an issue here:
flags must be set to a decimal number (4096) in this case, not binary 0x00001001 otherwise giving error.
Meanwhile 0x00001001 equals 4097 but on the documentation it is written that geofences are 4096 so
that should have been 0x00001000. ref: https://sdk.wialon.com/wiki/en/sidebar/ … t/resource
Maybe the api has changed since 2016 when this was replied...

My problem is although my request seems to work right now, it returns an empty geofence array:

My Request:

svc=core/search_items&params="spec":"itemsType":"avl_resource","propName":"zones_library","propType":"propitemname","propValueMask":"*","sortType":"sys_name"},"force":1,"flags":4096,"from":0,"to":0}&sid=xxxx

Response:

{"searchSpec":"itemsType":"avl_resource","propName":"zones_library","propValueMask":"*","sortType":"sys_name","propType":"propitemname","or_logic":"0"},"dataFlags":4096,"totalItemsCount":0,"indexFrom":0,"indexTo":0,"items":[]}

I'm sure I have geofences registered, I can see them in the web application.
I'm using a token generated for "Locator" application to get the session ID,
can this be the reason for that?

Thank you!
