Multidatamodels and API Gateway

Question

Hi forum!  
  
I have set up a multidatamodel with two models on it, model1 and model2.  
I can call the model from a Sagemaker notebook or locally using boto3 and invoke_endpoint. Everything works like a charm there.  
  
But I would like to set up an API with API Gateway - and that is proving troublesome. I keep getting a 403 "Unable to determine service/operation name to be authorized"-error.  
  
Is API Gateway supporting MultiDataModels? And is there any documentation or guides on how to make them interact?  
  
Best regards  
Elias

Answer

Yes, it is possible. There is no documentation of specifically working with API Gateway and SageMaker MultiDataModels. The trick is to pass the model as a header.  
See the documentation here:
