Global Opt-In Consent Guide
Detailed specifications for collecting prior express written consent before launching outbound campaigns globally. Covers opt-in wording parameters, disclosure scripts, DND suppression rules, and call recording notification guidelines to ensure full compliance.
DND Regulations & Compliance
Understanding customer preference regulations and custom blocklist lookup configurations. Maintain compliance by checking call lists against your user-provided DND registers and preference rules dynamically in real time.
Regional Voice Latency Metrics
Deep technical dive into the streaming voice pipeline, adaptive voice activity detection (VAD), and interruption cancellation parameters. Learn how Closerr minimizes speech processing delays using regional gateways.
CAG-First Database Caching Setup
Technical documentation explaining how to cache greeting scripts and document context to minimize Time to First Token dynamically. Implement fast Retrieval-Augmented Generation context lookups to prevent agent hallucinations and delays.
Developer Call Trigger Setup
Developers can trigger automated voice qualification campaigns by firing a POST request to Closerr's outbound gateway endpoint. Specify recipient details, configuration variables, and consent flags to launch the session instantly:
curl -X POST https://api.closerr.in/v1/calls \
-H "Authorization: Bearer cl_api_key_9872198" \
-H "Content-Type: application/json" \
-d '{
"phone_number": "+919876543210",
"agent_id": "agent_aria_102",
"variables": {
"lead_name": "Rohan Sharma",
"project_name": "Heights Tower C"
},
"compliance": {
"optin_consent_granted": true,
"trai_dnd_scrub": true
}
}'Our outbound gateway validates variables rapidly, respects configuration flags, and commands SIP trunk routers to launch the dialing sequence. The connection state is reported back via webhook events.
Developer SDK Libraries & API Key Management
To simplify implementation, Closerr publishes official SDK clients for multiple runtime environments. Developers can initialize the client using standard packages in Node.js, Python, or Go. The client automatically handles authentication header packaging, request retries, exponential backoffs, and webhook signature verifications out of the box, ensuring robust system integrations and reducing the overall lines of custom code your team needs to write.
API key security is critical. Ensure your application tokens are stored strictly in server-side environment variables (`.env` files) and never exposed on public client-side bundles. Closerr supports API key rotation policies and granular scopes. You can generate read-only access keys for dashboard telemetry reporting, and write-enabled keys strictly for outbound call queue triggers, maintaining a secure, zero-trust infrastructure.
