| Name | Type | Description | Notes |
|---|---|---|---|
| account_id | string | The social account ID to send from | |
| participant_id | string | Recipient identifier. For X this is the numeric user ID; for WhatsApp, the recipient phone number in international format (digits, country code included). Provide either this or participantUsername. | [optional] |
| participant_username | string | Recipient handle/username — an X or Bluesky handle (with or without @) or a Reddit username (with or without u/). Resolved via lookup. Provide either this or participantId. | [optional] |
| message | string | Text content of the message. At least one of message, attachment, or (for WhatsApp) templateName is required. | [optional] |
| skip_dm_check | bool | X/Twitter only. Skip the receives_your_dm eligibility check before sending. Use if you have already verified the recipient accepts DMs. | [optional] [default to false] |
| template_name | string | WhatsApp only. Name of the approved template to start the conversation with (required for WhatsApp). | [optional] |
| template_language | string | WhatsApp only. Template language code (e.g. en_US). | [optional] |
| template_params | string[] | WhatsApp only. Template variable values as one flat array, in the order the variables appear across the whole template: text-header variables first, then body variables, then one value per dynamic URL button (in button order). Works with positional placeholders ({{1}}, {{2}}, ...) and with named placeholders ({{name}}, {{company}} - how Meta Business Manager creates templates), where values fill the named slots in order of appearance. Example - a body with {{1}}, {{2}} plus a URL button https://example.com/{{1}} takes three values: [body1, body2, buttonSuffix]. Media headers (image, video, document) are filled automatically from the approved template and take no value here (use headerMedia to override the header asset per send). | [optional] |
| header_media | \Zernio\Model\CreateInboxConversationRequestHeaderMedia | [optional] |
