Orion notification complex payload - fiware-orion

Question

I'm trying to use Orion notification to send SMS with Plivo.
This is how I send an SMS directly with Plivo:
curl -X POST https://api.plivo.com/v1/Account/MAMDA5ZDJIMDM1/Message/ -L -u MAMDA5ZDJIM:YzhiNDJjODNhNDkxMjhiYTgxZD -H 'Content-Type: application/json' -d #- <<EOF
{
"src": "0039414141414",
"dst": "0039414747111",
"text": "test SMS"
}
EOF
How should I encode it in Orion? I tried:
curl localhost:1026/v2/subscriptions -s -S --header 'Content-Type: application/json' --header 'Accept: application/json' -d #- <<EOF
{
"description": "A subscription to get info about WS_UPPA_Sensor2",
"subject": {
"entities": [
{
"id": "Sensor1",
"type": "SensingDevice"
}
],
"condition": {
"attrs": [
"temperature"
]
}
},
"notification": {
"httpCustom": {
"url": "https://api.plivo.com/v1/Account/MAMDA5ZDJIMDM1NZVMZD/Message/",
"headers": {
"Authorization": "Basic TUFNREE1WkRKSU1ETTFOWlZNWkQ6WXpoaU5ESmpPRE5oTkRreE1qaGlZVGd4WkRkaE5qYzNPV1ZsTnpZMA=="
},
"payload": "{%22src%22%3A%2200393806412092%22%2C%22dst%22%3A%2200393806412093%22%2C%22text%22%3A%22test%20SMS%20from%20Waziup%22}"
},
"attrs": [
"temperature"
]
},
"expires": "2040-01-01T14:00:00.00Z",
"throttling": 5
}
EOF
Is there another way than percent encoding?

Answer 1

URL encoding (I understand is the one you refer by "percent encoding") is the only one which have an special treatment in custom notifications (details described as part of the Orion documentation).
In fact, taking into account the existing one is complete (I mean, any text can be expressed in the terms of URL encoding) there is no need of adding any other.
