Yes, you can append to an existing dataset via the REST API using the POST /v1/datasets/upload endpoint with the action parameter set to "append". The request body must include the dataset name and the new examples to add, either as JSON or multipart/form-data. This allows you to add new examples to an existing dataset, not just create a new one. See the API details and example payloads in the official documentation and source code.Would you like a code example or more details on the request format?Sources:
