PayWay Python API Docs | dltHub

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

Last updated:

PayWay REST API Reference provides access to core functionalities of PayWay services. Access depends on purchased modules. Sign up for a free test account to start using the API. The REST API base URL is https://api.payway.com.au/rest/v1 and all requests require HTTP Basic auth using your secret API key as the username (leave password blank).

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 PayWay data in under 10 minutes.


What data can I load from PayWay?

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

ResourceEndpointMethodData selectorDescription
root/GETRoot resource with links to available resources and hypermedia navigation
transactions/transactionsGETdataSearch/list transactions (paginated). Returns transactions in the response 'data' array
transaction/transactions/{transactionId}GETGet transaction details by transactionId
customers/customersGETdataList/search customers. Returns customers in 'data' array
customer/customers/{customerNumber}GETGet full customer model by customerNumber
payment_files/payment-filesGETdataList payment files (payments uploaded and their status)
payment_file_transactions/payment-files/{fileName}/transactionsGETdataGet transactions contained in a processed payment file (same format as transaction search)
receipts_files/receipts-filesGETdataList receipts (day reports)
merchants/merchantsGETdataList merchants

How do I authenticate with the PayWay API?

Send your secret API key as the HTTP Basic Authentication username. Leave the password blank. Include Accept: application/json to request JSON responses.

1. Get your credentials

  1. Log into your PayWay facility. 2) Go to Settings → REST API Keys (or REST API Keys under Settings). 3) Create or copy a Secret API Key. 4) Secret keys expire after one year; rotate or automate renewal as needed. 5) Use the secret key as the Basic auth username when calling the API (leave password blank).

2. Add them to .dlt/secrets.toml

[sources.payway_source] api_key = "T10000_SEC_your_secret_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 PayWay 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 payway_pipeline.py

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

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

Inspect your pipeline and data:

dlt pipeline payway_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 transactions and customers from the PayWay 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 payway_source(api_key=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://api.payway.com.au/rest/v1", "auth": { "type": "http_basic", "api_key": api_key, }, }, "resources": [ {"name": "transactions", "endpoint": {"path": "transactions", "data_selector": "data"}}, {"name": "customers", "endpoint": {"path": "customers", "data_selector": "data"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="payway_pipeline", destination="duckdb", dataset_name="payway_data", ) load_info = pipeline.run(payway_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("payway_pipeline").dataset() sessions_df = data.transactions.df() print(sessions_df.head())

SQL (DuckDB example):

SELECT * FROM payway_data.transactions LIMIT 10;

In a marimo or Jupyter notebook:

import dlt data = dlt.pipeline("payway_pipeline").dataset() data.transactions.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 PayWay 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.
