Memberstack Python API Docs | dltHub

Memberstack is an authentication and user management platform that provides an Admin REST API for managing members and account data. The REST API base URL is https://admin.memberstack.com and all requests require an X-API-KEY header containing a secret key.

dlt is an open-source Python library that handles authentication, pagination, and schema evolution automatically. dlthub provides AI context files that enable code assistants to generate production-ready pipelines. Install with uv add "dlt[hub]" and start loading Memberstack data in under 10 minutes.

What data can I load from Memberstack?

Here are some of the endpoints you can load from Memberstack:

---

How do I authenticate with the Memberstack API?

The API uses a secret key passed in the X-API-KEY header for all administrative requests. The key must be included in every request to authenticate successfully.

1. Get your credentials

To obtain your Memberstack API credentials, log in to your Memberstack dashboard. Navigate to the Dev Tools section and select Keys & IDs. Here you can view and manage both your public keys (for client-side use) and secret keys (for server-side Admin REST API use). Ensure you choose the appropriate key based on your environment: Test mode keys (prefixed with sk_sb_) for development, or Live mode keys (prefixed with sk_) for production. Note that Live mode keys only become available once you have an active billing method on your account.

2. Add them to .dlt/secrets.toml

Copy
[sources.memberstack_source]
memberstack_api_key = "sk_your_secret_key_here"

dlt reads this automatically at runtime — never hardcode tokens in your pipeline script. For production environments, see setting up credentials with dlt for environment variable and vault-based options.

---

How do I set up and run the pipeline?

Set up a virtual environment and install dlt:

Copy
uv init
uv add "dlt[hub]"

1. Install the dlt AI harness:

Copy
uv run dlthub ai init --agent <your-agent> # <agent>: claude | cursor | codex

This installs project rules, a secrets management skill, appropriate ignore files, and configures the dlt MCP server for your agent. Learn more →

2. Install the rest-api-pipeline toolkit:

Copy
uv run dlthub ai toolkit install rest-api-pipeline

This loads the skills and context about dlt the agent uses to build the pipeline iteratively, efficiently, and safely. The agent uses MCP tools to inspect credentials — it never needs to read your secrets.toml directly. Learn more →

3. Start LLM-assisted coding:

Use /find-source to load data from the Memberstack API into DuckDB.

The rest-api-pipeline toolkit takes over from here — it reads relevant API documentation, presents you with options for which endpoints to load, and follows a structured workflow to scaffold, debug, and validate the pipeline step by step.

4. Run the pipeline:

Copy
uv run python memberstack_pipeline.py

If everything is configured correctly, you'll see output like this:

Copy
Pipeline memberstack_pipeline load step completed in 0.26 seconds
1 load package(s) were loaded to destination duckdb and into dataset memberstack_data
The duckdb destination used duckdb:/memberstack.duckdb location to store data
Load package 1749667187.541553 is LOADED and contains no failed jobs

Inspect your pipeline and data:

Copy
uv run dlthub show

This opens the Pipeline Dashboard where you can verify pipeline state, load metrics, schema (tables, columns, types), and query the loaded data directly.

Python pipeline example

This example loads /members and /members/verify-token from the Memberstack API into DuckDB. It mirrors the endpoint and data selector configuration from the table above:

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

@dlt.source
def memberstack_source(api_key=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://admin.memberstack.com",
            "auth": {"type": "api_key", "api_key": api_key, "name": "X-API-KEY", "location": "header"},
        },
        "resources": [
            {"name": "members", "endpoint": {"path": "members", "data_selector": "data"}},
            {"name": "data_records_query", "endpoint": {"path": ":table/records/query", "data_selector": "data.records"}}
        ],
    }
    yield from rest_api_resources(config)


def get_data() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="memberstack_pipeline",
        destination="duckdb",
        dataset_name="memberstack_data",
    )
    load_info = pipeline.run(memberstack_source())
    print(load_info)

To add more endpoints, append entries from the resource table to the "resources" list using the same name, path, and data_selector pattern.

How do I query the loaded data?

Once the pipeline runs, dlt creates one table per resource. You can query with Python or SQL.

Python (pandas DataFrame):

Copy
import dlt

data = dlt.pipeline("memberstack_pipeline").dataset()
sessions_df = data.members.df()
print(sessions_df.head())

SQL (DuckDB example):

Copy
SELECT * FROM memberstack_data.members LIMIT 10;

In a marimo or Jupyter notebook:

Copy
import dlt

data = dlt.pipeline("memberstack_pipeline").dataset()
data.members.df().head()

See how to explore your data in marimo Notebooks and how to query your data in Python with dataset.

What destinations can I load Memberstack data to?

dlt supports loading into any of these destinations — only the destination parameter changes:

Change the destination in dlt.pipeline(destination="snowflake") and add credentials in .dlt/secrets.toml. See the full destinations list.
