Protect your FileMaker Data API solutions
Your REST API code must log in to a database session to access data:
- 
                                                
For FileMaker Server hosts: Use a FileMaker file account with a password, or use one of the other types of accounts supported by your FileMaker Server host.
 - 
                                                
For FileMaker Cloud hosts: Use the Claris ID account and password. See Log in to a database session using a Claris ID account (FileMaker Cloud).
 
Notes
- 
                                                
When defining account names and passwords for FileMaker Data API solutions, use printable ASCII characters, for example a-z, A-Z, and 0-9. For more secure account names and passwords, include punctuation characters such as "!" and "%," but do not include colons. See Creating and editing account access in FileMaker Pro Help.
