Quick Start

Quick-start code examples

See how common DropVM integration patterns can look in code before you move into the full API documentation.

Illustrative examples only. Replace example endpoints, parameters and credentials with the current values from the official DropVM API documentation.
Send Ringless Voicemail cURL
curl -X POST \ "https://api.example.com/v1/voicemail" \ -H "Authorization: Bearer YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "to": "+15551234567", "audio_url": "https://example.com/message.mp3" }'
Send an SMS Message JavaScript
const response = await fetch( 'https://api.example.com/v1/messages', { method: 'POST', headers: { Authorization: `Bearer ${API_KEY}`, 'Content-Type': 'application/json' }, body: JSON.stringify({ to: '+15551234567', message: 'Your appointment is tomorrow at 2 PM.' }) } );
Create or Update a Contact Python
import requests payload = { "phone": "+15551234567", "first_name": "Alex", "custom_fields": { "service_type": "Consultation" } } response = requests.post( "https://api.example.com/v1/contacts", json=payload, headers={"Authorization": f"Bearer {API_KEY}"} )
Launch a Campaign PHP
$payload = [ "campaign_name" => "Lead Follow-Up", "contact_list_id" => "LIST_ID", "message_id" => "MESSAGE_ID" ]; $ch = curl_init( "https://api.example.com/v1/campaigns" ); // Add auth headers and JSON body // using the current API documentation.
Verify a Webhook Event Node.js
app.post('/webhooks/dropvm', (req, res) => { const event = req.body; if (event.type === 'message.delivered') { console.log('Delivered:', event.data); } res.sendStatus(200); });
Retrieve Campaign Results cURL
curl \ "https://api.example.com/v1/campaigns/CAMPAIGN_ID" \ -H "Authorization: Bearer YOUR_API_KEY" # Example response concept: # { # "status": "completed", # "sent": 2480, # "delivered": 2361 # }

Developer FAQs

Frequently asked questions

Quick answers for developers integrating DropVM into applications, CRMs and automated workflows.

What can I build with the DropVM API?
The developer platform is intended to help teams connect DropVM outreach features to their own applications, CRM processes, contact workflows and internal automation.
How is API authentication handled?
Follow the current authentication method shown in the official API documentation. Keep production credentials private and never expose them in browser-side code or public repositories.
Can I send ringless voicemail programmatically?
Where supported by the current DropVM API, developers can connect voicemail actions to application logic, customer events and automated workflows.
Can I integrate SMS into my application?
DropVM developer resources are designed to support messaging integrations so your application can coordinate customer outreach with existing business logic.
Does DropVM support webhooks?
Webhooks can be used to notify your application when supported events occur, allowing your own systems to react without continuous polling.
Can I connect DropVM with my CRM?
Yes. Depending on your CRM and workflow, you may use native integrations, automation tools or the developer API to connect systems.
Is there an OpenAPI specification?
If available for your current API version, an OpenAPI specification can help with generated clients, testing tools and internal API documentation.
Are SDKs or packages available?
Check the current developer documentation for supported SDKs, libraries or packages, since availability can change as the developer platform evolves.
How should I test my integration?
Start with a limited development dataset, validate request and response handling, test webhook behavior, confirm error handling and verify compliance logic before moving to production.
Where should I look for the latest endpoint details?
Always use the official DropVM developer documentation as the source of truth for current endpoints, parameters, authentication and API behavior.
