Some users might be used to the full MARS client to access MARS. There are some limitations if you use the Access MARS service compared to the full MARS client:
- You can only use retrieve or list verbs. compute, read, write... are not available
- You can only execute one action at the time
- You can not use multi-target using the keywords, only one final single file can be transferred at the end of the execution. See how to How to organise the output in separate files - Web API FAQ
- You can only access to the archived data (no fdb access)
