Authsignal Python API Docs | dltHub

Build a Authsignal-to-database pipeline in Python using dlt with AI Workbench support for Claude Code, Cursor, and Codex.

Last updated:

The REST API base URL is https://api.authsignal.com/v1/client and The Authsignal Client API primarily uses bearer authentication with a short-lived token. Some passkey-related endpoints also support basic authentication using a tenant ID..

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 pip install "dlt[workspace]" and start loading Authsignal data in under 10 minutes.


What data can I load from Authsignal?

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

ResourceEndpointMethodData selectorDescription
user_authenticatorsuser-authenticatorsGETRetrieve user authenticators
passkey_initiate_challengeuser-authenticators/passkey/initiate-challengePOSTInitiate a passkey challenge
passkey_authentication_optionsuser-authenticators/passkey/authentication-optionsPOSTGenerate passkey authentication options
passkey_verify_authenticationuser-authenticators/passkey/authenticationPOSTVerify passkey authentication
passkey_register_optionsuser-authenticators/passkey/registration-optionsPOSTGenerate passkey registration options
passkey_registeruser-authenticators/passkey/registerPOSTRegister a passkey

How do I authenticate with the Authsignal API?

The Authsignal Client API uses bearer authentication, requiring a short-lived token in the Authorization header. Certain passkey endpoints utilize basic authentication with the tenant ID as the username and an empty password.

1. Get your credentials

To obtain the bearer token, call the Server API's Track Action endpoint or use a Server SDK. For basic authentication, use your tenant ID as the username, which can be found in your Authsignal dashboard.

2. Add them to .dlt/secrets.toml

[sources.authsignal_source] token = "your_bearer_token_here" tenant_id = "your_tenant_id_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:

uv venv && source .venv/bin/activate uv pip install "dlt[workspace]"

1. Install the dlt AI Workbench:

dlt 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:

dlt ai toolkit rest-api-pipeline install

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 Authsignal 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:

python authsignal_pipeline.py

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

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

Inspect your pipeline and data:

dlt pipeline authsignal_pipeline 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 user_authenticators and passkey_authentication from the Authsignal API into DuckDB. It mirrors the endpoint and data selector configuration from the table above:

import dlt from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources @dlt.source def authsignal_source(token, tenant_id=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://api.authsignal.com/v1/client", "auth": { "type": "bearer, http_basic", "token, tenant_id": token, tenant_id, }, }, "resources": [ {"name": "user_authenticators", "endpoint": {"path": "user-authenticators"}}, {"name": "passkey_authentication", "endpoint": {"path": "user-authenticators/passkey/authentication"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="authsignal_pipeline", destination="duckdb", dataset_name="authsignal_data", ) load_info = pipeline.run(authsignal_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):

import dlt data = dlt.pipeline("authsignal_pipeline").dataset() sessions_df = data.user_authenticators.df() print(sessions_df.head())

SQL (DuckDB example):

SELECT * FROM authsignal_data.user_authenticators LIMIT 10;

In a marimo or Jupyter notebook:

import dlt data = dlt.pipeline("authsignal_pipeline").dataset() data.user_authenticators.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 Authsignal data to?

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

DestinationExample value
DuckDB (local, default)"duckdb"
PostgreSQL"postgres"
BigQuery"bigquery"
Snowflake"snowflake"
Redshift"redshift"
Databricks"databricks"
Filesystem (S3, GCS, Azure)"filesystem"

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