All API calls can fail with network errors, rate limits (429), validation errors (422), or authentication errors (401). Always handle errors in production code:

curl \
  -X POST \
  -H "Authorization: Bearer $TELNYX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "entityType": "PRIVATE_PROFIT",
  "displayName": "ABC Mobile",
  "country": "US",
  "email": "support@example.com",
  "vertical": "TECHNOLOGY"
}' \
  "https://api.telnyx.com/v2/10dlc/brand"

Common error codes: 401 invalid API key, 403 insufficient permissions, 404 resource not found, 422 validation error (check field formats), 429 rate limited (retry with exponential backoff).

Important Notes

Pagination: List endpoints return paginated results. Use page[number] and page[size] query parameters to navigate pages. Check meta.total_pages in the response.

Operational Caveats

10DLC is sequential: create the brand first, then submit the campaign, then attach messaging infrastructure such as the messaging profile.
Registration calls are not enough by themselves. Messaging cannot use the campaign until the assignment step completes successfully.
Treat registration status fields as part of the control flow. Do not assume the campaign is send-ready until the returned status fields confirm it.

Reference Use Rules

Do not invent Telnyx parameters, enums, response fields, or webhook fields.

If the parameter, enum, or response field you need is not shown inline in this skill, read references/api-details.md before writing code.
Before using any operation in ## Additional Operations, read the optional-parameters section and the response-schemas section.
Before reading or matching webhook fields beyond the inline examples, read the webhook payload reference.

Webhook Verification

Telnyx signs webhooks with Ed25519. Each request includes telnyx-signature-ed25519 and telnyx-timestamp headers. Always verify signatures in production:

# Telnyx signs webhooks with Ed25519 (asymmetric — NOT HMAC/Standard Webhooks).
# Headers sent with each webhook:
#   telnyx-signature-ed25519: base64-encoded Ed25519 signature
#   telnyx-timestamp: Unix timestamp (reject if >5 minutes old for replay protection)
#
# Get your public key from: Telnyx Portal > Account Settings > Keys & Credentials
# Use the Telnyx SDK in your language for verification (client.webhooks.unwrap).
# Your endpoint MUST return 2xx within 2 seconds or Telnyx will retry (up to 3 attempts).
# Configure a failover URL in Telnyx Portal for additional reliability.

Webhooks

These webhook payload fields are inline because they are part of the primary integration path.

`brandId`	string	Brand ID associated with the campaign.
`campaignId`	string	The ID of the campaign.
`createDate`	string	Unix timestamp when campaign was created.
