On success, response is empty with status 202 Accepted and returns something
like:
{
"task_id": "ba83ee09-aa83-1901-bb11-e645b52fc558",
}
When the election finally gets processed, the callback_url is called with a
POST containing the protInfo.xml file generated jointly by each
authority, following this example response:
{
"status": "finished",
"reference": {
"election_id": "d9e5ee09-03fa-4890-aa83-2fc558e645b5",
"action": "POST /election"
},
"session_data": [{
"session_id": "deadbeef-03fa-4890-aa83-2fc558e645b5",
"publickey": ["<pubkey codified in hexadecimal>"]
}]
}
Note that this protInfo.xml will contain the election public key, but
also some other information. In particular, it's worth noting that
the http and hint servers' urls for each authority could change later,
if election-orchestra needs it.
If there was an error, then the callback will be called following this
example format:
{
"status": "error",
"reference": {
"session_id": "d9e5ee09-03fa-4890-aa83-2fc558e645b5",
"action": "POST /election"
},
"data": {
"message": "error message"
