I am trying to use the Azure Digital Twins API to create twins of the model I have uploaded. So far, I can successfully create one twin per model per API request.
Is there any way to create multiple twins from multiple models in 1 request?
So far I have tried parsing various iterations of the following as the JSON payload.

I am getting the following errors:
{
"errors": {
"twinCreate": [
"The twinCreate field is required."
],
"digitalTwinsGraph.digitalTwins": [
"Invalid property identifier character: {. Path 'digitalTwinsGraph.digitalTwins', line 306, position 12."
]
},
"type": "https://tools.ietf.org/html/rfc7231#section-6.5.1",
"title": "One or more validation errors occurred.",

"extensions": {
"traceId": "|bfeb7647-4044d66d0401388a."
}
}
I cannot seem to find any docs explaining if this is possible or even what the twinCreate field is.
Unfortunately, you can't do this in one API call. You can add multiple models at the same time, but you can't add multiple twins in one call.
It would make a good feature request.
