+# Sign Request API improvements 
+
+[Sign Request status][1] parameter now has two additional values:
+
+* `finalizing` to reflect the state when all signers have signed the request, but the final document with signatures and the signing log has not been generated yet.
+* `error_finalizing` to reflect the state when the `finalizing` phase did not complete successfully.
