Alternative ways to update multiple objects

2

Here’s a thought, why not just manage it yourself as an async resource?

EDIT: Ok, actually read the comment and I think that is exactly his suggestion. Maybe without the async part.

The way I would approach this is to create a resource which represents a bulk operation, maybe not even on the errand resource. I wouldn’t concern myself with what the operation is, the resource representation should give that information.

/bulktransactions/.....

That way your payload could be something like this:

{
  "data": {
    "type": "bulktransaction",
    "attributes": {
      "resources": [{"type":"errands"}],
      "operations": [
        {"id":123,"method":"PATCH", "payload":1},
        {"id":124,"method":"PATCH", "payload":1},
        {"id":125,"method":"PATCH","payload":1}
      ],
      "payload":[
        {"id":1,
          "value":{
            "data": {
              "type": "errands",
              "attributes": {
                "dirty": true
              }
            }
          }
        }
      ]
    }
  }
}

You could return a location header for the bulk transaction resource itself, and get all the info and updates you needed from there.
