Update a sub-composition's content

To update a sub-composition's content, you'll need two things:

• The app token for the particular instance of the control app you're using
• The sub-composition's name or ID and its payload structure

With that data on hand

1. Prepare a PATCH request to https://app.singular.live/apiv2/controlapps/:appToken/control, which is the endpoint to update a control app.
2. Replace :appToken with the app token for your app instance.

3. Add a request body with the actual sub-composition ID and payload structure, and include the updates you'd like to make. The request body should look like this, but with sub-composition name or ID and payload data filled in.

Sub-composition name

[
    {
        "subCompositionName": "your-subcomposition-name",
        "payload": {
          "controlnode-field": "control node content"
        }
    }
]

Sub-composition ID

[
    {
        "subCompositionId": "your-subcomposition-id",
        "payload": {
          "controlnode-field": "control node content"
        }
    }
]

After sending the request, you should get a 200 OK response with a payload of { "success": true }.
