FIS Profile Python API Docs | dltHub
Build a FIS Profile-to-database pipeline in Python using dlt with AI harness support for Claude Code, Cursor, and Codex.
Last updated:
FIS Profile is a core banking platform that exposes banking services through a RESTful API tier managed via the FIS Code Connect gateway. The REST API base URL is https://api.fisglobal.com and all requests require a Bearer token generated via OAuth 2.0 flow.
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 FIS Profile data in under 10 minutes.
What data can I load from FIS Profile?
Here are some of the endpoints you can load from FIS Profile:
| Resource | Endpoint | Method | Data selector | Description |
|---|---|---|---|---|
| accounts | /accounts/{accountId}/transactions | GET | transactions | Returns transaction history for a specified account. |
| accounts | /accounts/{accountId} | GET | Get specific account details. | |
| payments | /payments | GET | List payment records. | |
| customers | /customers | GET | Retrieve customer profiles. | |
| balances | /accounts/{accountId}/balances | GET | Get account balance information. |
How do I authenticate with the FIS Profile API?
The API uses OAuth 2.0 access tokens. Tokens are generated through the FIS Code Connect portal using application consumer keys and secrets; authorized requests typically require the 'Authorization: Bearer ' header.
1. Get your credentials
To obtain API credentials for FIS Profile (via FIS Code Connect), follow these steps: 1. Register for an account on the FIS Code Connect portal. 2. Work directly with your FIS account manager to request access to the relevant environment (Sandbox or Readiness/Production). 3. Once approved, log in to the Code Connect portal and navigate to 'My Collections' to view your application. 4. Within the application settings, request the necessary keys. 5. If using OAuth 2.0 or API key methods, your account team will provide the specific client credentials or assist in generating them within the portal.
2. Add them to .dlt/secrets.toml
[sources.fis_profile_source] fis_client_id = "your_client_id_here" fis_client_secret = "your_client_secret_here" # If using simple API key authentication: fis_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 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 FIS Profile 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 fis_profile_pipeline.py
If everything is configured correctly, you'll see output like this:
Pipeline fis_profile_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset fis_profile_data The duckdb destination used duckdb:/fis_profile.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 oauth/token and services from the FIS Profile 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 fis_profile_source(access_token=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://api.fisglobal.com", "auth": {"type": "bearer", "token": access_token}, }, "resources": [ {"name": "transactions", "endpoint": {"path": "accounts/{accountId}/transactions", "data_selector": "transactions"}}, {"name": "accounts", "endpoint": {"path": "accounts", "data_selector": "accounts"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="fis_profile_pipeline", destination="duckdb", dataset_name="fis_profile_data", ) load_info = pipeline.run(fis_profile_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("fis_profile_pipeline").dataset() sessions_df = data.transactions.df() print(sessions_df.head())
SQL (DuckDB example):
SELECT * FROM fis_profile_data.transactions LIMIT 10;
In a marimo or Jupyter notebook:
import dlt data = dlt.pipeline("fis_profile_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 FIS Profile data to?
dlt supports loading into any of these destinations — only the destination parameter changes:
| Destination | Example 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.
