SignNow Python API Docs | dltHub

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

Last updated:

SignNow is an e-signature platform that enables developers to embed legally binding document signing and management workflows into their applications. The REST API base URL is https://api.signnow.com and all requests require a Bearer token or an API key passed in the Authorization header.

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 SignNow data in under 10 minutes.


What data can I load from SignNow?

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

ResourceEndpointMethodData selectorDescription
documents/documentGETRetrieve a list of all documents
document_groups/user/documentgroupsGETRetrieve a list of document groups
template_copies/v2/templates/{template_id}/copiesGETRetrieve a list of documents created from a template
signing_links/v2/application/signing-linksGETRetrieve a list of signing links
folders/folderGETRetrieve a list of folders

How do I authenticate with the SignNow API?

Authentication requires an Authorization header with a Bearer token. This token is obtained via an OAuth 2.0 flow (POST /oauth2/token) using client credentials or user credentials.

1. Get your credentials

To obtain API credentials, sign in to the airSlate SignNow developer dashboard. Navigate to the API section to create a new application; this action generates a Client ID and a Client Secret. These credentials, combined with your account email and password, are used to authenticate and generate a Bearer access token via the POST /oauth2/token endpoint. Once authenticated, you can also view and copy your API key directly from the API Key tab within your application's details in the dashboard.

2. Add them to .dlt/secrets.toml

[sources.signnow_source] api_key = "REPLACE_ME"

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 init uv add "dlt[hub]"

1. Install the dlt AI harness:

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:

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 SignNow 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:

uv run python signnow_pipeline.py

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

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

Inspect your pipeline and data:

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 document and oauth2/token from the SignNow 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 signnow_source(api_key=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://api.signnow.com", "auth": {"type": "bearer", "token": api_key}, }, "resources": [ {"name": "documents", "endpoint": {"path": "document"}}, {"name": "document_groups", "endpoint": {"path": "user/documentgroups"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="signnow_pipeline", destination="duckdb", dataset_name="signnow_data", ) load_info = pipeline.run(signnow_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("signnow_pipeline").dataset() sessions_df = data.documents.df() print(sessions_df.head())

SQL (DuckDB example):

SELECT * FROM signnow_data.documents LIMIT 10;

In a marimo or Jupyter notebook:

import dlt data = dlt.pipeline("signnow_pipeline").dataset() data.documents.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 SignNow 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.
