For array values (like checkbox, multiple select, etc.) - do not wrap macros into quotes
Parameters:
- parent_id, child_id - single ID or array of IDs
- context - either "child" or "parent"
"child" means we replace / update (add) / disconnect child(ren) of parent(s)
"parent" means we replace / update (add) / disconnect parent(s) of child(ren) - store_items_type - "replace" / "update" / "disconnect"
Example:
Relation is Many to Many
Set two children with IDs of 267234 and 267235 to parent with ID of 686
Parameters:
- parent_id - 686
- child_id - [267234,267235]
- context - "child" so that we replace children for the parent
- store_items_type - "replace"
{
"parent_id": 686,
"child_id": [267234,267235],
"context": "child",
"store_items_type": "replace",
}If you need to update relation meta, only one pair of parent / child should be updated.
Example:
Update relation meta for the parent-child pair 686-267234
"meta" is an object where keys are meta field keys, and values are meta field values;
for timestamp types you can pass date in a human readable format, it will be converted automatically.
All possible meta types have an example value here.
