I have provided the property token and local mbox name in the POST API, I was able to get the 200 response
POST > https://xxx.tt.omtrdc.net/rest/v1/delivery?client=xxx&sessionId=100290adcb6a14043309f8789b21b0c18ba
Body as raw > json
{
"context": {
"channel": "web",
"browser" : {
"host" : "production"
},
"address" : {
},
"screen" : {
"width" : 1200,
"height": 1400
}
},
"property" : {
"token": "f6fb2018-92d3-f3f5-36ee-40e7affb1804"
},
"execute": {
"mboxes" : [
{
"name" : "customMbox",
"index" : 1
}
]
}
}
Can you try with some local mbox nae and not the global mbox name ?
