Hi Eugen,

The format for relation removal has changed from the way the doc describes it and what’s worse is there is a regression in the current version. I opened an internal ticket and as soon as the problem is fixed, I will post information here on the updated format.

I apologize about the inconvenient this causes for you.

Regards,
Mark

Hi, Mark.

Hi, Eugene! Here’s how you can remove relation:
For example, you have 2 tables Address (street, city) and Person (name, 1:1 relation to-> Address)
To remove the relation from between person and address, you can execute this request:

curl 
-H application-id:application-id-value-from-console
-H secret-key:secret-key-value-from-console 
-H Content-Type:application/json
-X PUT 
-d {
 "address": null,
 "created": 1452264617000,
 "name": "Andrew",
 "___class": "Person",
 "ownerId": null,
 "updated": 1452273668000,
 "objectId": "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX",
 "__meta": "{\"relationRemovalIds\":{},\"selectedProperties\":[\"__updated__meta\",\"address\",\"created\",\"name\",\"___class\",\"ownerId\",\"updated\",\"objectId\"],\"relatedObjects\":{\"address\":[\"44F70FDE-032E-DA70-FF4C-741E568F2E00\"]}}"
}"
-v [url=https://api.backendless.com/v1/data/Person/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX]https://api.backendless.com/v1/data/Person/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX[/url]

where “XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX” is objectId of the person which relation to Address table is to be deleted,
“address”: null is a new (deleted) relation.
