Load Simpletexting data to DuckDB

SimpleTexting is a REST SMS/MMS messaging platform that provides programmatic access to send messages, manage contacts, keywords, campaigns, and webhooks. Everything needed to build a working Simpletexting → DuckDB pipeline is on this page: the API's base URL, authentication, endpoints, pagination and incremental field — plus a prompt that hands the whole job to your coding agent.

Build your Simpletexting to DuckDB pipeline

Paste this prompt into Claude, Codex, or Cursor. The agent does the rest.

PromptCopy prompt
Run uvx dlthub-init@latest to build a pipeline from Simpletexting to DuckDB and run it on dltHub

That scaffolds a dltHub workspace and installs the dltHub AI harness — the project rules, the secrets-management skill, and the dlt MCP server your agent needs to work safely. From there it reads the Simpletexting API, proposes the endpoints to load, then writes, runs and validates the pipeline while you review rather than type. Credentials are inspected through MCP tools, so your agent never reads secrets.toml itself. How the LLM-native workflow works →

Prefer to write it yourself? Every fact the agent uses is below.

Simpletexting API at a glance

These values come from the Simpletexting API reference — the authoritative source if anything here looks out of date.

---

How do I authenticate with the Simpletexting API?

All requests require an API token sent in the Authorization header as a Bearer token, formatted as 'Authorization: Bearer '. An additional 'Accept: application/json' header is standard practice for REST API interactions.

1. Get your credentials

1. Sign up for a SimpleTexting account. 2. Request API access by emailing support@simpletexting.net or clicking the question mark/support icon in your dashboard, providing details about your intended API use case. 3. Once approved, navigate to your dashboard in the upper right-hand corner, click the person icon, select Profile & Settings, and go to the API tab (or Integrations > Developer Tools > API & Webhooks) to retrieve your API token.

2. Add them to .dlt/secrets.toml

Copy
[sources.simpletexting_source]
api_token = "your_api_token_here"

dlt reads this file automatically at runtime. With the harness, the setup-secrets skill prompts you for the values and never handles the raw credential in chat. For production, see setting up credentials with dlt.

What Simpletexting data can I load into DuckDB?

These are the Simpletexting endpoints dlt can load into DuckDB:

How do I load only new Simpletexting records?

Simpletexting exposes page on api/messages, so dlt can request only the records that changed since the last run. Set it as the cursor_path and dlt tracks the high-water mark for you between runs.

Copy
{"name": "messages", "endpoint": {
    "path": "api/messages",
    "data_selector": "content",
    "incremental": {"cursor_path": "page", "initial_value": "2024-01-01T00:00:00Z"},
}}

On the first run dlt loads everything from initial_value; on every run after that it requests only what changed and appends with write_disposition="merge" if you set a primary key. See incremental loading.

---

What does the generated Simpletexting pipeline look like?

A standard dlt REST API pipeline — the same code you would write by hand, loading messaging/sent/list and contacts from the Simpletexting API into DuckDB:

Copy
import dlt
from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources

@dlt.source
def simpletexting_source(api_token=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://api-app2.simpletexting.com/v2",
            "auth": {"type": "bearer", "token": api_token},
        },
        "resources": [
            {"name": "messages", "endpoint": {"path": "api/messages", "data_selector": "content"}},
            {"name": "contacts", "endpoint": {"path": "api/contacts", "data_selector": "content"}}
        ],
    }
    yield from rest_api_resources(config)


def load_simpletexting_to_duckdb() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="simpletexting_pipeline",
        destination="duckdb",
        dataset_name="simpletexting_data",
    )
    load_info = pipeline.run(simpletexting_source())
    print(load_info)


if __name__ == "__main__":
    load_simpletexting_to_duckdb()

Run it with python simpletexting_pipeline.py. The agent iterates on this until it loads cleanly — you review and approve, rather than write it from scratch.

How do I query Simpletexting data in DuckDB?

dlt creates one table per resource. Query the loaded data with Python or SQL — or ask your agent to, through the MCP server's execute_sql_query tool.

Python (pandas DataFrame):

Copy
import dlt

data = dlt.pipeline("simpletexting_pipeline").dataset()
df = data.messages.df()
print(df.head())

SQL:

Copy
SELECT * FROM simpletexting_data.messages LIMIT 10;

See querying your data with dataset and exploring it in marimo notebooks.

How do I deploy the Simpletexting to DuckDB pipeline in production?

The pipeline runs locally, which is ideal for prototyping and one-off analysis. When you need it on a schedule, monitored on every load, and shared with your team, deploy the same dlt code on the dltHub platform — no infrastructure to maintain. The prompt above already ends with "run it on dltHub", so your agent can take it there directly.

• Deploy & schedule — run the pipeline as a managed job with automatic retries.
• Monitor — observable job queues, alerting, and load metrics for every run.
• Transform — promote raw Simpletexting loads into governed, documented models.
• Visualize & share — explore data in notebooks and publish live dashboards instead of static screenshots.

What other destinations can I load Simpletexting data to?

dlt loads into any of these — only the destination argument changes:

Set dlt.pipeline(destination="snowflake") and add credentials in .dlt/secrets.toml. On the dltHub platform the same pipeline runs against a managed Iceberg lakehouse. See the full destinations list.
