Twikey Python API Docs | dltHub

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

Last updated:

Twikey API allows software partners to integrate payment solutions. Essential requests require a valid session token in the Authorization header. Use SDKs for reliable connection and mandate management. The REST API base URL is https://api.twikey.com and All requests require a session token obtained via an API key exchange, which is then 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 pip install "dlt[workspace]" and start loading Twikey data in under 10 minutes.


What data can I load from Twikey?

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

ResourceEndpointMethodData selectorDescription
mandate_detail/creditor/mandate/detailGETGet details of a specific mandate
mandate_query/creditor/mandate/queryGETSubscriptionsQuery mandates
legal/creditor/legalGETGet legal information
invoice_bulk/creditor/invoice/bulkGETGet invoices in bulk
transaction/creditor/transactionGETGet transactions
transaction_detail/creditor/transaction/detailGETGet details of a specific transaction
transaction_bulk/creditor/transaction/bulkGETGet transactions in bulk
iban_blacklist/creditor/ibanblacklistGETGet IBAN blacklist
payment_methods/creditor/payment/methodsGETGet available payment methods
files/creditor/filesGETFilesGet files
login/creditorPOSTAuthorizationObtain session token

How do I authenticate with the Twikey API?

Authentication requires an API key to be exchanged for a session token via a POST request to the /creditor endpoint. This session token, valid for 24 hours, must then be included in the Authorization header for all subsequent API calls.

1. Get your credentials

Obtain your API key from the Twikey Merchant Dashboard.

2. Add them to .dlt/secrets.toml

[sources.twikey_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:

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 Twikey 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 twikey_pipeline.py

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

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

Inspect your pipeline and data:

dlt pipeline twikey_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 mandate_query and transaction from the Twikey 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 twikey_source(api_key=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://api.twikey.com", "auth": { "type": "bearer", "Authorization": api_key, }, }, "resources": [ {"name": "mandate_query", "endpoint": {"path": "creditor/mandate/query", "data_selector": "Subscriptions"}}, {"name": "transaction", "endpoint": {"path": "creditor/transaction"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="twikey_pipeline", destination="duckdb", dataset_name="twikey_data", ) load_info = pipeline.run(twikey_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("twikey_pipeline").dataset() sessions_df = data.mandate_query.df() print(sessions_df.head())

SQL (DuckDB example):

SELECT * FROM twikey_data.mandate_query LIMIT 10;

In a marimo or Jupyter notebook:

import dlt data = dlt.pipeline("twikey_pipeline").dataset() data.mandate_query.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 Twikey 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.
