Error Handling

Tamr Core API calls return conventional HTTP success or error status codes.

On success, calls return a response code of 200 and the expected object.

Error Types

For errors, the API provides information about what went wrong. All errors are returned as JSON objects. An example error response follows:

  "status": 404,
  "class": "com.tamr.common.except.ResourceNotFoundException",
  "message": "No Operation found with ID [1000000]",
  "stackTrace": [
  "causedBy": null,
  "service": "Public API"

The following table describes the data and metadata for an error.

classThe class that threw the error.
