Finmatics Python API Docs | dltHub

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

Last updated:

Finmatics offers a REST API for custom automations. You can connect and retrieve data at any stage of the processing pipeline. This API enables seamless integration and data management. The REST API base URL is https://api.finmatics.com and All requests require a JWT token passed in the Authorization header as jwt=TOKEN..

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 Finmatics data in under 10 minutes.


What data can I load from Finmatics?

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

ResourceEndpointMethodData selectorDescription
companies/api/v1/companies/GETRetrieve list of companies.
clients/api/v1/clients/GETRetrieve list of clients.
documents/api/v1/documents/GETRetrieve list of documents.
e_invoices/api/v1/e-invoices/GETRetrieve list of e‑invoices.
gl_accounts/api/v1/gl_accounts/GETRetrieve general ledger accounts.
booking_types/api/v1/booking_types/GETRetrieve booking types.
partners/api/v1/partners/GETRetrieve partner information.
partner_banks/api/v1/partner_banks/GETRetrieve all partner banks.
cost_centers/api/v1/cost_centers/GETRetrieve cost centers/objects.
training_data/api/v1/training_data/GETRetrieve training data records.

How do I authenticate with the Finmatics API?

Obtain a JWT via POST /api/v1/token_auth/ with username and password; include the token in the header 'Authorization: jwt=TOKEN' for all calls.

1. Get your credentials

  1. Log in to the Finmatics web portal.
  2. Go to the "Integrations" or "API Access" area.
  3. Create a new API token (or retrieve existing client ID/secret).
  4. Record the username and password (or client secret) for use in the token_auth POST request.
  5. Store the obtained token securely for inclusion in request headers.

2. Add them to .dlt/secrets.toml

[sources.finmatics_source] token = "your_jwt_token_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 Finmatics 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 finmatics_pipeline.py

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

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

Inspect your pipeline and data:

dlt pipeline finmatics_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 companies from the Finmatics 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 finmatics_source(token=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://api.finmatics.com", "auth": { "type": "bearer", "token": token, }, }, "resources": [ {"name": "documents", "endpoint": {"path": "api/v1/documents/"}}, {"name": "companies", "endpoint": {"path": "api/v1/companies/"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="finmatics_pipeline", destination="duckdb", dataset_name="finmatics_data", ) load_info = pipeline.run(finmatics_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("finmatics_pipeline").dataset() sessions_df = data.documents.df() print(sessions_df.head())

SQL (DuckDB example):

SELECT * FROM finmatics_data.documents LIMIT 10;

In a marimo or Jupyter notebook:

import dlt data = dlt.pipeline("finmatics_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 Finmatics 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.
