Hi Everyone,

I am trying to insert Leads in an outbound campaign and need help in setting the leadTimezone and nextDialTime parameters

I am using this API 

https://engage.ringcentral.com/voice/api/v1/admin/accounts/accountId/campaigns/campaignId/leadLoader/direct 

found here

Engage Voice API Reference | RingCentral Developers 

I am using this body parameter

 

{
    "description": "Prospect customers",
    "dialPriority": "IMMEDIATE",
    "duplicateHandling": "RETAIN_ALL",
    "listState": "ACTIVE",
    // "timeZoneOption": "EXPLICIT",
    "phoneNumbersI18nEnabled": true,
    "internationalNumberFormat": true,
    "uploadLeads":e {
        "nextDialTime": "2025-08-27T17:34:34.000+0000",
        "externId": "44",
        "leadPhone": "+919940044284",
        "leadTimezone": "IST"
    }]
}

Any help in what I should do correctly?
