# 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: `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](references/api-details.md) before writing code.
- Before using any operation in `## Additional Operations`, read [the optional-parameters section](references/api-details.md#optional-parameters) and [the response-schemas section](references/api-details.md#response-schemas).
- Before reading or matching webhook fields beyond the inline examples, read [the webhook payload reference](references/api-details.md#webhook-payload-fields).

## Core Tasks

### Create a brand

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

`client.messaging_10dlc.brand.create()` — `POST /10dlc/brand`

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `entity_type` | object | Yes | Entity type behind the brand. |
| `display_name` | string | Yes | Display name, marketing name, or DBA name of the brand. |
| `country` | string | Yes | ISO2 2 characters country code. |
| `email` | string | Yes | Valid email address of brand support contact. |
| `vertical` | object | Yes | Vertical or industry segment of the brand. |
| `company_name` | string | No | (Required for Non-profit/private/public) Legal company name. |
| `first_name` | string | No | First name of business contact. |
| `last_name` | string | No | Last name of business contact. |
| ... | | | +16 optional params in [references/api-details.md](references/api-details.md) |

```python
telnyx_brand = client.messaging_10dlc.brand.create(
    country="US",
    display_name="ABC Mobile",
    email="support@example.com",
    entity_type="PRIVATE_PROFIT",
    vertical="TECHNOLOGY",
)
print(telnyx_brand.identity_status)
```

Primary response fields:
- `telnyx_brand.brand_id`
- `telnyx_brand.identity_status`
- `telnyx_brand.status`
- `telnyx_brand.display_name`
- `telnyx_brand.state`
- `telnyx_brand.alt_business_id`

### Submit a campaign

Campaign submission is the compliance-critical step that determines whether traffic can be provisioned.

`client.messaging_10dlc.campaign_builder.submit()` — `POST /10dlc/campaignBuilder`

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `brand_id` | string (UUID) | Yes | Alphanumeric identifier of the brand associated with this ca... |
| `description` | string | Yes | Summary description of this campaign. |
| `usecase` | string | Yes | Campaign usecase. |
| `age_gated` | boolean | No | Age gated message content in campaign. |
| `auto_renewal` | boolean | No | Campaign subscription auto-renewal option. |
| `direct_lending` | boolean | No | Direct lending or loan arrangement |
| ... | | | +29 optional params in [references/api-details.md](references/api-details.md) |

```python
telnyx_campaign_csp = client.messaging_10dlc.campaign_builder.submit(
    brand_id="BXXXXXX",
    description="Two-factor authentication messages",
    usecase="2FA",
    sample_messages=["Your verification code is {{code}}"],
)
print(telnyx_campaign_csp.brand_id)
```

Primary response fields:
- `telnyx_campaign_csp.campaign_id`
- `telnyx_campaign_csp.brand_id`
- `telnyx_campaign_csp.campaign_status`
- `telnyx_campaign_csp.submission_status`
- `telnyx_campaign_csp.failure_reasons`
- `telnyx_campaign_csp.status`

### 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()` — `POST /10dlc/phoneNumberAssignmentByProfile`

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `messaging_profile_id` | string (UUID) | Yes | The ID of the messaging profile that you want to link to the... |
| `campaign_id` | string (UUID) | Yes | The ID of the campaign you want to link to the specified mes... |
| `tcr_campaign_id` | string (UUID) | No | The TCR ID of the shared campaign you want to link to the sp... |

```python
response = client.messaging_10dlc.phone_number_assignment_by_profile.assign(
    messaging_profile_id="4001767e-ce0f-4cae-9d5f-0d5e636e7809",
    campaign_id="CXXX001",
)
print(response.messaging_profile_id)
```

Primary response fields:
- `response.messaging_profile_id`
- `response.campaign_id`
- `response.task_id`
- `response.tcr_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](references/api-details.md#webhook-payload-fields) before writing the handler.
