When you try to hit a webservice (a REST API) via PostMan tool sometimes you may get a response saying “413 Error – Request Entity Too large”. This error would generally occur when you are trying to send a large file or lot of records via PostMan (When you are trying to send or test with large amount of data) this error may occur.
This errors is not due to Postman’s limitation. It’s more due to a limitation set on the server where the max file upload size is set to lesser number say 100MB or 50MB etc., In order to fix this error, ask the Server Admin to change the file upload size in Apache or Nginx configurations. Once that is changed you won’t get that error again
