# Update application

> Use the updateAcceptorApplication GraphQL mutation to add or modify information on an existing acceptor application before submission.

Use updateAcceptorApplication to add or update missing information in the application. Like the create mutation, this mutation does not perform validation on the application data - validation only occurs when you submit the application.

### Update application fields

You can update any field in the application through updateAcceptorApplication.
