Telnyx 10DLC - Python

Installation

pip install telnyx

Setup

import os
from telnyx import Telnyx

client = Telnyx(
    api_key=os.environ.get("TELNYX_API_KEY"),  # This is the default and can be omitted
)

All examples below assume client is already initialized as shown above.

Error Handling

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

import telnyx

try:
    telnyx_brand = client.messaging_10dlc.brand.create(
        country="US",
        display_name="ABC Mobile",
        email="[e-mail]",
        entity_type="PRIVATE_PROFIT",
        vertical="TECHNOLOGY",
    )
except telnyx.APIConnectionError:
    print("Network error — check connectivity and retry")
except telnyx.RateLimitError:
    import time
    time.sleep(1)  # Check Retry-After header for actual delay
except telnyx.APIStatusError as e:
    print(f"API error {e.status_code}: {e.message}")
    if e.status_code == 422:
        print("Validation error — check required fields and formats")

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 methods return an auto-paginating iterator. Use for item in page_result: to iterate through all pages automatically.

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.

Core Tasks

Parameter	Type	Required	Description
messaging_profile_id	string (UUID)	Yes	The ID of the messaging profile that you want to link to the...

Webhook Verification

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

# In your webhook handler (e.g., Flask — use raw body, not parsed JSON):
@app.route("/webhooks", methods=["POST"])
def handle_webhook():
    payload = request.get_data(as_text=True)  # raw body as string
    headers = dict(request.headers)
    try:
        event = client.webhooks.unwrap(payload, headers=headers)
    except Exception as e:
        print(f"Webhook verification failed: {e}")
        return "Invalid signature", 400
    # Signature valid — event is the parsed webhook payload
    print(f"Received event: {event.data.event_type}")
    return "OK", 200

Webhooks

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

Campaign Status Update

Field	Type	Description
brandId	string	Brand ID associated with the campaign.
campaignId	string	The ID of the campaign.
createDate	string	Unix timestamp when campaign was created.
cspId	string	Alphanumeric identifier of the CSP associated with this campaign.
isTMobileRegistered	boolean	Indicates whether the campaign is registered with T-Mobile.
type	enum: TELNYX_EVENT, REGISTRATION, MNO_REVIEW, TELNYX_REVIEW, NUMBER_POOL_PROVISIONED, NUMBER_POOL_DEPROVISIONED, TCR_EVENT, VERIFIED
description	string	Description of the event.
status	enum: ACCEPTED, REJECTED, DORMANT, success, failed	The status of the campaign.

If you need webhook fields that are not listed inline here, read the webhook payload reference before writing the handler.
