​Not unexpectedly, OSHA does not have their secure web site up and running and they are not yet accepting electronic data submissions at this time.  Updates will be posted to the web page shown below when they are available.
 
If and when the secure web site is up and running, OSHA will offer three options for data submission: 

• Manual entry of data into a web-based form.
• Upload a CSV file to process single or multiple establishments. 
• Users of automated recordkeeping systems will have the ability to transmit data electronically via an application programming interface (API).

 
The OSHA website to keep an eye on is here.
