Maximum file size upload through custom REST API

Hey - Has anyone implemented file uploads to Salesforce Files through Custom Rest Webservice, if yes can you please let me know the max file size upload. I am getting System.LimitException: JSON string exceeds heap size limit\n\nExternal entry point" when tested through postman for a file size of 4 MB.

Appreciate any help on this.

Thanks

Using the SObject Basic Information or SObject Rows APIs, the maximum file size for uploads is 2 GB for ContentVersion objects and 500 MB for all other eligible standard objects. Using the SObject Collections API, the maximum total size of all files in a single request is 500 MB.

The above limitations are for the standard API, I am looking specifically to custom REST API. Any help, please.

Thanks
