Acculynx Python API Docs | dltHub

AccuLynx is a REST API for roofing contractors to access and integrate AccuLynx account data (jobs, contacts, company settings, milestones, estimates, etc.). The REST API base URL is https://api.acculynx.com/api/v2 and all requests require a Bearer token (API Key) for authentication.

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 Acculynx data in under 10 minutes.

What data can I load from Acculynx?

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

---

How do I authenticate with the Acculynx API?

Authentication uses an API Key provided by an AccuLynx account administrator. Include the API key as a Bearer token in the Authorization header (Authorization: Bearer <API_KEY>) on all requests.

1. Get your credentials

1. Sign in to your AccuLynx account as an administrator.
2. Navigate to Account/Company settings (API or developer settings).
3. Create and name a new API Key for the location you want to access.
4. Copy the generated API Key and store it securely; use it as the Bearer token in the Authorization header.

2. Add them to .dlt/secrets.toml

Copy
[sources.acculynx_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:

Copy
uv venv && source .venv/bin/activate
uv pip install "dlt[workspace]"

1. Install the dlt AI Workbench:

Copy
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:

Copy
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 Acculynx 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:

Copy
python acculynx_pipeline.py

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

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

Inspect your pipeline and data:

Copy
dlt pipeline acculynx_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 milestones and jobs from the Acculynx API into DuckDB. It mirrors the endpoint and data selector configuration from the table above:

Copy
import dlt
from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources

@dlt.source
def acculynx_source(api_key=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://api.acculynx.com/api/v2",
            "auth": {
                "type": "bearer",
                "api_key": api_key,
            },
        },
        "resources": [
            {"name": "milestones", "endpoint": {"path": "company-settings/job-file-settings/workflow-milestones"}},
            {"name": "jobs", "endpoint": {"path": "jobs"}}
        ],
    }
    yield from rest_api_resources(config)


def get_data() -> None:
    pipeline = dlt.pipeline(
        pipeline_name="acculynx_pipeline",
        destination="duckdb",
        dataset_name="acculynx_data",
    )
    load_info = pipeline.run(acculynx_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):

Copy
import dlt

data = dlt.pipeline("acculynx_pipeline").dataset()
sessions_df = data.milestones.df()
print(sessions_df.head())

SQL (DuckDB example):

Copy
SELECT * FROM acculynx_data.milestones LIMIT 10;

In a marimo or Jupyter notebook:

Copy
import dlt

data = dlt.pipeline("acculynx_pipeline").dataset()
data.milestones.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 Acculynx data to?

dlt supports loading into any of these destinations — only the destination parameter changes:

Change the destination in dlt.pipeline(destination="snowflake") and add credentials in .dlt/secrets.toml. See the full destinations list.

Troubleshooting

Authentication failures

If you receive 401/403, verify the API Key is correct and included as Authorization: Bearer <API_KEY>. Ensure the key was created for the correct AccuLynx company location and not expired or revoked.

Rate limits

AccuLynx documentation does not publish detailed rate limits; if you encounter 429 responses, implement exponential backoff and retry with jitter. Contact AccuLynx support if limits block your integration.

Pagination

Many list endpoints return paginated results. Inspect response headers and body for pagination metadata (page/next links) and follow the documented query parameters (page, pageSize) to iterate through results.

Ensure that the API key is valid to avoid 401 Unauthorized errors. Also, verify endpoint paths and parameters to avoid 404 Not Found errors.
