Tempo Python API Docs | dltHub
Build a Tempo-to-database pipeline in Python using dlt with AI Workbench support for Claude Code, Cursor, and Codex.
Last updated:
Tempo is a time‑tracking and reporting platform that offers a REST API for managing worklogs, accounts, projects and related data. The REST API base URL is https://api.tempo.io and All requests require a Bearer token in the Authorization 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 pip install "dlt[workspace]" and start loading Tempo data in under 10 minutes.
What data can I load from Tempo?
Here are some of the endpoints you can load from Tempo:
| Resource | Endpoint | Method | Data selector | Description |
|---|---|---|---|---|
| worklogs | /4/worklogs | GET | values | Retrieve worklog entries matching query parameters. |
| accounts | /4/accounts | GET | values | List Tempo accounts accessible to the token. |
| projects | /4/projects | GET | values | List projects that can be referenced in worklogs. |
| teams | /4/teams | GET | values | Retrieve team information. |
| users | /4/users | GET | values | Get user details associated with worklogs. |
How do I authenticate with the Tempo API?
Authentication is performed via an OAuth 2.0 Bearer token passed in the Authorization header (e.g., "Authorization: Bearer $token").
1. Get your credentials
- Log in to Tempo.
- Navigate to Settings → Data Access → API Integration.
- Click "New Token".
- Provide a name, optional expiry date, and select the required scopes.
- Click "Create" – the token value will be displayed once; copy it immediately.
- Save the token securely; you can regenerate it later if needed.
2. Add them to .dlt/secrets.toml
[sources.tempo_time_tracking_source] access_token = "your_access_token_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 Tempo 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 tempo_time_tracking_pipeline.py
If everything is configured correctly, you'll see output like this:
Pipeline tempo_time_tracking_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset tempo_time_tracking_data The duckdb destination used duckdb:/tempo_time_tracking.duckdb location to store data Load package 1749667187.541553 is LOADED and contains no failed jobs
Inspect your pipeline and data:
dlt pipeline tempo_time_tracking_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 worklogs and accounts from the Tempo 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 tempo_time_tracking_source(access_token=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://api.tempo.io", "auth": { "type": "bearer", "token": access_token, }, }, "resources": [ {"name": "worklogs", "endpoint": {"path": "4/worklogs", "data_selector": "values"}}, {"name": "accounts", "endpoint": {"path": "4/accounts", "data_selector": "values"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="tempo_time_tracking_pipeline", destination="duckdb", dataset_name="tempo_time_tracking_data", ) load_info = pipeline.run(tempo_time_tracking_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("tempo_time_tracking_pipeline").dataset() sessions_df = data.worklogs.df() print(sessions_df.head())
SQL (DuckDB example):
SELECT * FROM tempo_time_tracking_data.worklogs LIMIT 10;
In a marimo or Jupyter notebook:
import dlt data = dlt.pipeline("tempo_time_tracking_pipeline").dataset() data.worklogs.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 Tempo 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.
Troubleshooting
Authentication Errors
- If the token is missing or invalid, the API returns a 401 Unauthorized response with an
errorsobject containing a message such as "Invalid token".
Rate Limiting
- Tempo enforces request quotas. When the limit is exceeded the service responds with HTTP status 429 Too Many Requests. Clients should back‑off and retry after a delay.
Pagination
- List endpoints return paginated results. Use the
limitandoffsetquery parameters to navigate pages. The response includes atotalCountfield indicating the total number of records.
General Errors
- Error responses follow the structure
{ "errors" : { "message" : "Error details" } }. Inspect themessagefield for specifics.
Ensure that the API key is valid to avoid 401 Unauthorized errors. Also, verify endpoint paths and parameters to avoid 404 Not Found errors.
