Integrate DNC LATAM with Twilio

DNC LATAM · Compliance guides

The pattern is simple: your dialer or CPaaS app calls the DNC LATAM API before Twilio connects. Twilio places the session you authorize. It does not query Mexico REPEP (PROFECO), Argentina Registro Nacional No Llame (AAIP), or Colombia RNE (CRC) for you. If you skip the gate, a "DNC-looking" US stack can still launch +52, +54, or +57 traffic.

This page uses only the public request and response shape from docs.dnclatam.com. CPaaS packaging: DNC for CPaaS. Generic dialer: integrate with a dialer.

Where the check belongs

1. Your backend receives an outbound intent (agent click, queue, or campaign worker).
2. You read the destination number and pick mx, ar, or co.
3. You POST that country and a phone array to DNC LATAM from the server.
4. If the number is in prohibited_numbers_to_call, you do not tell Twilio to connect.
5. If the number is in safe_numbers_to_call, you proceed with your existing Twilio flow.
6. If the number is invalid, you fix the input. Do not dial it "to see."

A country code is not enough. Resolve the full E.164 destination before you pick a list. +52, +54, and +57 go here. A +1 number is not automatically a US number: NANP also covers Canada and Caribbean destinations. Send US numbers to your FTC / TCPA vendor. Do not treat every +1 as that vendor's job. Twilio plus EVS7 or DNC.com does not cover REPEP. DNC.com alternative for LATAM.

Request shape (public docs)

Synchronous v1, from the published quickstart. Authenticate with a Bearer API key. Every POST /v1/scrub requires an Idempotency-Key header. Missing it returns 400 missing_idempotency_key. Generate a new opaque UUID for every logical batch. Reuse that key only when retrying the exact same country and phones array. Do not derive it from phone numbers. Do not call this from browser code.

POST https://api.dnclatam.com/v1/scrub
Authorization: Bearer $DNC_LATAM_API_KEY
Idempotency-Key: $DNC_LATAM_IDEMPOTENCY_KEY
Content-Type: application/json

{
  "country": "mx",
  "phones": ["+52 55 1234 5678", "55 8765 4321", "abc"]
}

Set DNC_LATAM_IDEMPOTENCY_KEY to a fresh UUID before the first POST of that batch (the public quickstart uses uuidgen). Use ar for Argentina and co for Colombia. v1 is for up to 10,000 inputs and a 15-second budget. Larger list loads use durable POST /v2/scrub as documented. CSV stays in the panel, not in Twilio.

Example numbers and record IDs are illustrative. Their sample classification explains the format. It is not a live-registry statement. safe_numbers_to_call means not found on the selected official list at check time. It is not consent and not permission under every other rule. scrub_record is the phone-free screening record attached on a successful v1 scrub. Persist it. v1 does not keep it. No phones in that object. Result classes: response guide. Record product page: screening records.

Twilio-specific notes we will not invent

We will not invent Twilio webhook field names, TwiML verbs, or Studio widget IDs on this page. Your Twilio implementation already has a server hop that decides whether to start an outbound session. Put the DNC LATAM POST on that hop. Refuse prohibited. Persist the dated screening record in your system. v1 documents x-retention: zero on successful responses: we do not keep the phone list.

Batch the campaign file before agents can click. Realtime-check the number that just arrived in the CRM. Batch vs realtime. Aircall sibling: integrate with Aircall.
