Telnyx 10DLC - Python

Installation

bash

pip install telnyx

Setup

python

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:

python

import telnyx

try:
    telnyx_brand = client.messaging_10dlc.brand.create(
        country="US",
        display_name="ABC Mobile",
        email="support@example.com",
        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:

invalid API key,

insufficient permissions,

resource not found,

validation error (check field formats),

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

Brand registration is the entrypoint for any US A2P 10DLC campaign flow.

Assign a messaging profile to a campaign

Messaging profile assignment is the practical handoff from registration to send-ready messaging infrastructure.

client.messaging_10dlc.phone_number_assignment_by_profile.assign()

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

Primary response fields:

```
response.messaging_profile_id
```
```
response.campaign_id
```
```

Webhook Verification

Telnyx signs webhooks with Ed25519. Each request includes

telnyx-signature-ed25519

and

telnyx-timestamp

headers. Always verify signatures in production:

python

# 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.
