WhatsApp Business API Python API Docs | dltHub

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

Last updated:

The WhatsApp Business Platform provides enterprise-grade APIs for businesses to message and interact with customers on WhatsApp. The REST API base URL is https://graph.facebook.com and all requests require a Bearer token.

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 WhatsApp Business API data in under 10 minutes.


What data can I load from WhatsApp Business API?

Here are some of the endpoints you can load from WhatsApp Business API:

ResourceEndpointMethodData selectorDescription
waba/{waba_id}GETRetrieve WABA details
phone_numbers/{waba_id}/phone_numbersGETdataList registered phone numbers
message_templates/{waba_id}/message_templatesGETdataList message templates
assigned_users/{waba_id}/assigned_usersGETdataList assigned users to WABA
business_account_solutions/{waba_id}/solutionsGETdataList associated Multi-Partner Solutions

How do I authenticate with the WhatsApp Business API API?

All requests require an Authorization header with a Bearer token: 'Authorization: Bearer <ACCESS_TOKEN>'.

1. Get your credentials

  1. Navigate to the Meta for Developers App Dashboard (developers.facebook.com/apps) and create/select your Meta app. 2. Ensure the WhatsApp product is added to your app. 3. Navigate to Business Settings (business.facebook.com/settings) and select your Business Portfolio/Account. 4. In the left sidebar, under the Users section, select System Users. 5. Click Add to create a new system user with an Admin role. 6. Select the new system user, click Assign Assets, and assign your Meta App (select 'Manage app') and your WhatsApp Business Account (select 'Manage WhatsApp Business accounts') with 'Full control'. 7. Click Generate token, select your app, and ensure the following permissions are granted: 'business_management', 'whatsapp_business_messaging', and 'whatsapp_business_management'. 8. Copy the token immediately; this is your permanent access token for API requests.

2. Add them to .dlt/secrets.toml

[sources.whatsapp_business_api_source] access_token = "YOUR_META_ACCESS_TOKEN" whatsapp_business_account_id = "YOUR_WABA_ID" phone_number_id = "YOUR_PHONE_NUMBER_ID"

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 WhatsApp Business API 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 whatsapp_business_api_pipeline.py

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

Pipeline whatsapp_business_api_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset whatsapp_business_api_data The duckdb destination used duckdb:/whatsapp_business_api.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 /{phone_number_id}/messages and /{whatsapp_business_account_id}/message_templates from the WhatsApp Business API 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 whatsapp_business_api_source(access_token=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://graph.facebook.com", "auth": {"type": "bearer", "token": access_token}, }, "resources": [ {"name": "message_templates", "endpoint": {"path": "{waba_id}/message_templates", "data_selector": "data"}}, {"name": "phone_numbers", "endpoint": {"path": "{waba_id}/phone_numbers", "data_selector": "data"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="whatsapp_business_api_pipeline", destination="duckdb", dataset_name="whatsapp_business_api_data", ) load_info = pipeline.run(whatsapp_business_api_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("whatsapp_business_api_pipeline").dataset() sessions_df = data.message_templates.df() print(sessions_df.head())

SQL (DuckDB example):

SELECT * FROM whatsapp_business_api_data.message_templates LIMIT 10;

In a marimo or Jupyter notebook:

import dlt data = dlt.pipeline("whatsapp_business_api_pipeline").dataset() data.message_templates.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 WhatsApp Business API 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.
