SignNow Python API Docs | dltHub

SignNow is an e‑signature platform that provides REST APIs for document creation, management and signing. The REST API base URL is https://api.signnow.com and all requests require a Bearer token for authentication.

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 SignNow data in under 10 minutes.

What data can I load from SignNow?

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

---

How do I authenticate with the SignNow API?

SignNow uses Bearer token authentication; include the API key in the Authorization header as "Bearer {API_KEY}".

1. Get your credentials

1. Verify your email address on SignNow.
2. Log in to the SignNow developer portal.
3. The dashboard opens automatically and shows your first application in Development mode.
4. Click the application to view its details.
5. In the API Key tab, copy the displayed API key.
6. Store the API key securely; it will be used as a Bearer token in requests.

2. Add them to .dlt/secrets.toml

Copy
[sources.signnow_source]
api_key = "your_api_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 venv && source .venv/bin/activate
uv pip install "dlt[workspace]"

1. Install the dlt AI Workbench:

Copy
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:

Copy
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 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:

Copy
python signnow_pipeline.py

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

Copy
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:

Copy
dlt pipeline signnow_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 documents and folders from the SignNow 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 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": "v2/documents", "data_selector": "documents"}},
            {"name": "folders", "endpoint": {"path": "v2/folders", "data_selector": "folders"}}
        ],
    }
    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):

Copy
import dlt

data = dlt.pipeline("signnow_pipeline").dataset()
sessions_df = data.documents.df()
print(sessions_df.head())

SQL (DuckDB example):

Copy
SELECT * FROM signnow_data.documents LIMIT 10;

In a marimo or Jupyter notebook:

Copy
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:

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

Troubleshooting

Authentication Errors

• 401 Unauthorized – The Bearer token is missing, malformed, or expired. Ensure the API key is correct and included in the Authorization header.

Rate Limits

• 429 Too Many Requests – SignNow enforces rate limits per account. Back‑off and retry after the Retry-After header value.

Pagination

• Many list endpoints return paginated results using page and per_page query parameters. Check the response for next_page_url or similar fields to retrieve subsequent pages.

Ensure that the API key is valid to avoid 401 Unauthorized errors. Also, verify endpoint paths and parameters to avoid 404 Not Found errors.
