Sms 10dlc Registration

SMS 10DLC Registration

Use this skill for US A2P SMS over 10-digit long codes. Separate the compliance evidence packet from the exact Sent API request; they have different schemas and validators.

Current Sent resource model

There is no standalone brand CRUD path in the current v3 API.

• Create a dedicated brand inside POST /v3/profiles using brand and inherit_tcr_brand: false.
• List/create campaigns with GET|POST /v3/profiles/{profileId}/campaigns.
• Update/delete with PUT|DELETE /v3/profiles/{profileId}/campaigns/{campaignId}.

Reject guidance that reintroduces a free-standing brand path.

Choose inheritance deliberately

Inherited campaigns are read-only. A profile cannot supply brand while brand inheritance is true.

Two validation layers

Evidence readiness packet

The private packet uses the explicit internal version sent-10dlc-evidence/v1 and snake_case evidence fields. It is not an API payload.

python scripts/validate_10dlc_packet.py evidence.json

Collect legal identity, public website/policy links, consent proof, message flow, opt-in/opt-out/help responses and keywords, use cases, and realistic samples. See references/10dlc-evidence-checklist.md.

Sent campaign request

The API request uses exact camelCase and a campaign wrapper:

{
  "campaign": {
    "name": "Acme account notifications",
    "description": "Account and delivery notifications for opted-in customers.",
    "type": "App",
    "useCases": [
      {
        "messagingUseCaseUs": "ACCOUNT_NOTIFICATION",
        "sampleMessages": [
          "Acme Example: Your account preference was updated. Reply STOP to opt out."
        ]
      }
    ],
    "volume": "2000",
    "messageFlow": "Customers opt in in account settings before notifications begin.",
    "privacyPolicyLink": "https://example.com/privacy",
    "termsAndConditionsLink": "https://example.com/terms",
    "optinMessage": "Acme Example: You are subscribed. Reply STOP to opt out.",
    "optoutMessage": "Acme Example: You are unsubscribed and will receive no more messages.",
    "helpMessage": "Acme Example: Visit https://example.com/support for help.",
    "optinKeywords": "START,YES",
    "optoutKeywords": "STOP,UNSUBSCRIBE",
    "helpKeywords": "HELP,INFO"
  },
  "sandbox": true
}

Validate it with:

python scripts/validate_campaign_payload.py campaign.json

API use cases

Support all 13 current values:

MARKETING, ACCOUNT_NOTIFICATION, CUSTOMER_CARE, FRAUD_ALERT, TWO_FA, DELIVERY_NOTIFICATION, SECURITY_ALERT, M2M, MIXED, HIGHER_EDUCATION, POLLING_VOTING, PUBLIC_SERVICE_ANNOUNCEMENT, and LOW_VOLUME.

Each use case structurally accepts 1–5 samples, each no longer than 1,024 characters. The compliance layer requires at least two samples for marketing and mixed traffic, including low-volume mixed. Keep that policy distinction visible instead of pretending OpenAPI requires two for all traffic.

Volume and status

volume is optional and, when supplied, is a numeric string. Values below "2000" use the documented low-volume tier; "2000" is the boundary to the next tier.

Campaign responses currently expose statuses SENT_CREATED, ACTIVE, and EXPIRED, plus submittedToTCR. Preserve unknown future status strings. Do not confuse a successful Sent record creation with TCR submission or carrier activation.

Safe workflow

1. Confirm this is US A2P 10DLC traffic and the actual sending business is identified.
2. Select brand/campaign inheritance.
3. Validate the versioned evidence packet.
4. Create or confirm the profile brand.
5. Translate evidence into the exact camelCase campaign request.
6. Validate locally and use sandbox: true.
7. Show the payload and obtain confirmation before a real create/update/delete.
8. Store profile ID, campaign ID, submittedToTCR, raw status, and review evidence.
9. Complete the profile with required webHookUrl only after prerequisites are ready.

Never use real consumer data in fixtures or samples. Use references/tcr-use-cases.md for classification and references/10dlc-rejection-remediation.md for failures.
