Help needed with Export Data Pump using API

Question

Hi All,
Am trying to do an export data pump feature using the API.
while the export as well as import works fine from the command line, its failing with the API.
This is the command line program:
expdp pxperf/dba@APPN QUERY=dev_pool_data:\"WHERE TIME_NUM > 1204884480100\" DUMPFILE=EXP_DEV.dmp tables=PXPERF.dev_pool_data
Could you help me how should i achieve the same as above in Oracle Data Pump API
DECLARE
h1 NUMBER;
h1 := dbms_datapump.open('EXPORT','TABLE',NULL,'DP_EXAMPLE10','LATEST');
dbms_datapump.add_file(h1,'example3.dmp','DATA_PUMP_TEST',NULL,1);
dbms_datapump.add_file(h1,'example3_dump.log','DATA_PUMP_TEST',NULL,3);
dbms_datapump.metadata_filter(h1,'NAME_LIST','(''DEV_POOL_DATA'')');
END;
Also in the API i want to know how to export and import multiple tables (selective tables only) using one single criteria like "WHERE TIME_NUM > 1204884480100\"

Yes, I have read the Oracle doc.
I was able to proceed as below: but it gives error.

i have a table called LDEV_PERF_DATA and its in schema XPSLPERF.
value => '(where "XP_TIME_NUM > 1204884480100")',above is the condition i want to filter the data.
However, the below snippet works fine.

filetype => DBMS_DATAPUMP.KU$_FILE_TYPE_LOG_FILE);
DBMS_DATAPUMP.start_job(l_dp_handle);
DBMS_DATAPUMP.detach(l_dp_handle);
END;

I dont want to export all contents as the above, but want to export data based on some conditions and only on selective tables.
Any help is highly appreciated.
