Fieldpulse Python API Docs | dltHub

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

Last updated:

FieldPulse is a field service management platform that provides a REST API for accessing assets, customers, jobs, invoices, projects and other business data. The REST API base URL is https://ywe3crmpll.execute-api.us-east-2.amazonaws.com/stage and all requests require an API key in the x-api-key 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 add "dlt[hub]" and start loading Fieldpulse data in under 10 minutes.


What data can I load from Fieldpulse?

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

ResourceEndpointMethodData selectorDescription
customerscustomersGETRetrieve list of customers
jobsjobsGETRetrieve list of jobs
projectsprojectsGETRetrieve list of projects
invoicesinvoicesGETRetrieve list of invoices
estimatesestimatesGETRetrieve list of estimates
usersusersGETRetrieve list of users

How do I authenticate with the Fieldpulse API?

Authentication is performed by passing an API key in the 'x-api-key' request header. You must contact support@fieldpulse.com to obtain this token.

1. Get your credentials

FieldPulse does not currently offer a self-serve dashboard for API key generation. To obtain an API key: 1. Log in to your FieldPulse account. 2. Navigate to the Help Center or use the in-app chat widget (bottom right corner of the screen). 3. Contact the FieldPulse support team at support@fieldpulse.com or via chat to request access to the API. 4. Once approved, the support team will issue an API token, which must be passed in the 'x-api-key' header for all REST API requests.

2. Add them to .dlt/secrets.toml

[sources.fieldpulse_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 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 Fieldpulse 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 fieldpulse_pipeline.py

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

Pipeline fieldpulse_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset fieldpulse_data The duckdb destination used duckdb:/fieldpulse.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 assets and customers from the Fieldpulse 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 fieldpulse_source(api_key=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://ywe3crmpll.execute-api.us-east-2.amazonaws.com/stage", "auth": {"type": "api_key", "api_key": api_key, "name": "x-api-key", "location": "header"}, }, "resources": [ {"name": "customers", "endpoint": {"path": "customers"}}, {"name": "jobs", "endpoint": {"path": "jobs"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="fieldpulse_pipeline", destination="duckdb", dataset_name="fieldpulse_data", ) load_info = pipeline.run(fieldpulse_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("fieldpulse_pipeline").dataset() sessions_df = data.customers.df() print(sessions_df.head())

SQL (DuckDB example):

SELECT * FROM fieldpulse_data.customers LIMIT 10;

In a marimo or Jupyter notebook:

import dlt data = dlt.pipeline("fieldpulse_pipeline").dataset() data.customers.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 Fieldpulse 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.
