Encompass Developer Connect Python API Docs | dltHub
Build a Encompass Developer Connect-to-database pipeline in Python using dlt with AI harness support for Claude Code, Cursor, and Codex.
Last updated:
Encompass Developer Connect enables developers to configure, customize, and administer loan information and resources programmatically through REST APIs. The REST API base URL is https://api.elliemae.com/encompass/v1/ and all requests require a Bearer token obtained via OAuth 2.0 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 add "dlt[hub]" and start loading Encompass Developer Connect data in under 10 minutes.
What data can I load from Encompass Developer Connect?
Here are some of the endpoints you can load from Encompass Developer Connect:
| Resource | Endpoint | Method | Data selector | Description |
|---|---|---|---|---|
| loans | /encompass/v3/loans | GET | Retrieve a list of loans (requires specific query parameters for list context) | |
| loan_pipeline | /encompass/v1/loanPipeline | POST | Search loan pipeline with filters and cursor-based pagination | |
| loan_pipeline_v3 | /encompass/v3/loanPipeline | POST | V3 Loan Pipeline search with improved pagination | |
| loan_ucd_fields | /encompass/v3/loans/{loanId}/ucdFields | GET | Retrieve UCD field definitions for a specific loan | |
| canonical_fields | /encompass/v1/loanPipeline/canonicalFields | GET | Retrieve a list of accepted canonical field names for pipeline queries |
How do I authenticate with the Encompass Developer Connect API?
All API requests require an OAuth 2.0 access token passed in the Authorization HTTP header using the Bearer scheme (e.g., Authorization: Bearer ).
1. Get your credentials
To obtain API credentials, you must have Encompass Super Administrator privileges. Navigate to the Encompass web interface, click on 'My Account' in the top navigation menu, and select 'API Key'. You will be prompted to sign in with your Super Admin credentials (Instance Name/SmartClient ID, User ID, and Password). Upon successful login, the screen will display your Client ID (OAuth) and Client Secret. Ensure you copy these values immediately as they are required for authentication.
2. Add them to .dlt/secrets.toml
[sources.encompass_developer_connect_source] access_token = "REPLACE_ME"
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 Encompass Developer Connect 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 encompass_developer_connect_pipeline.py
If everything is configured correctly, you'll see output like this:
Pipeline encompass_developer_connect_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset encompass_developer_connect_data The duckdb destination used duckdb:/encompass_developer_connect.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 /oauth2/v1/token and /loans from the Encompass Developer Connect 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 encompass_developer_connect_source(access_token=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://api.elliemae.com/encompass/v1/", "auth": {"type": "bearer", "token": access_token}, }, "resources": [ {"name": "loan_pipeline", "endpoint": {"path": "encompass/v1/loanPipeline"}}, {"name": "loan_pipeline_v3", "endpoint": {"path": "encompass/v3/loanPipeline"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="encompass_developer_connect_pipeline", destination="duckdb", dataset_name="encompass_developer_connect_data", ) load_info = pipeline.run(encompass_developer_connect_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("encompass_developer_connect_pipeline").dataset() sessions_df = data.loan_pipeline.df() print(sessions_df.head())
SQL (DuckDB example):
SELECT * FROM encompass_developer_connect_data.loan_pipeline LIMIT 10;
In a marimo or Jupyter notebook:
import dlt data = dlt.pipeline("encompass_developer_connect_pipeline").dataset() data.loan_pipeline.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 Encompass Developer Connect 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.
