OK - that's setting the OID of the trap that you wish to send.

Not OK! Why have you changed this OID?
The OID of the object SNMPv2-MIB::snmpTrapOID is 1.3.6.1.3.1.1.4.1
So this second value should be left as
oid objid_snmptrap[] = { 1, 3, 6, 1, 3, 1, 1, 4, 1, 0 };

The first varbind in the payload specifies which trap you are sending.
This is of the form
snmpTrapOID.0 = {theOIDofMyTrap}
You've changed this to be
theOIDofMyTrap = {theOIDofMyTrap}
which is wrong.
The agent trap-handling code looks for the snmpTrapOID.0 assignment,
and rejects any request where this doesn't appear.
