Loading Data from Capsule CRM to PostgreSQL Using dlt in Python
Join our Slack community or book a call with our support engineer Violetta.
Loading data from Capsule CRM to PostgreSQL using the open-source Python library dlt is a streamlined process designed to enhance your data management capabilities. Capsule CRM is a user-friendly customer relationship management platform that helps businesses manage customer interactions, track tasks, analyze sales, and automate workflows. On the other hand, PostgreSQL is a robust, open-source object-relational database system known for its ability to handle complex data workloads efficiently. By leveraging dlt, you can easily transfer data from Capsule CRM to PostgreSQL, enabling you to benefit from both platforms' strengths. This documentation will guide you through the steps required to set up and execute this data transfer process. For more information about Capsule CRM, visit their website.

Getting started with your pipeline locally
dlt-init-openapi0. Prerequisites
dlt and dlt-init-openapi requires Python 3.9 or higher. Additionally, you need to have the pip package manager installed, and we recommend using a virtual environment to manage your dependencies. You can learn more about preparing your computer for dlt in our installation reference.
1. Install dlt and dlt-init-openapi
First you need to install the dlt-init-openapi cli tool.
pip install dlt-init-openapi
The dlt-init-openapi cli is a powerful generator which you can use to turn any OpenAPI spec into a dlt source to ingest data from that api. The quality of the generator source is dependent on how well the API is designed and how accurate the OpenAPI spec you are using is. You may need to make tweaks to the generated code, you can learn more about this here.
# generate pipeline
# NOTE: add_limit adds a global limit, you can remove this later
# NOTE: you will need to select which endpoints to render, you
# can just hit Enter and all will be rendered.
dlt-init-openapi capsule_crm --url https://raw.githubusercontent.com/dlt-hub/openapi-specs/main/open_api_specs/Business/capsule_crm.yaml --global-limit 2
cd capsule_crm_pipeline
# install generated requirements
pip install -r requirements.txt
The last command will install the required dependencies for your pipeline. The dependencies are listed in the requirements.txt:
dlt>=0.4.12
You now have the following folder structure in your project:
capsule_crm_pipeline/
├── .dlt/
│ ├── config.toml # configs for your pipeline
│ └── secrets.toml # secrets for your pipeline
├── rest_api/ # The rest api verified source
│ └── ...
├── capsule_crm/
│ └── __init__.py # TODO: possibly tweak this file
├── capsule_crm_pipeline.py # your main pipeline script
├── requirements.txt # dependencies for your pipeline
└── .gitignore # ignore files for git (not required)
1.1. Tweak capsule_crm/__init__.py
This file contains the generated configuration of your rest_api. You can continue with the next steps and leave it as is, but you might want to come back here and make adjustments if you need your rest_api source set up in a different way. The generated file for the capsule_crm source will look like this:

return rest_api_source(source_config)
2. Configuring your source and destination credentials
dlt-init-openapi will try to detect which authentication mechanism (if any) is used by the API in question and add a placeholder in your secrets.toml.
The dlt cli will have created a .dlt directory in your project folder. This directory contains a config.toml file and a secrets.toml file that you can use to configure your pipeline. The automatically created version of these files look like this:
generated config.toml
[runtime]
log_level="INFO"
[sources.capsule_crm]
# Base URL for the API
base_url = "https://api.capsulecrm.com"
generated secrets.toml
[sources.capsule_crm]
# secrets for your capsule_crm source
token = "FILL ME OUT" # TODO: fill in your credentials
2.1. Adjust the generated code to your usecase
At this time, the dlt-init-openapi cli tool will always create pipelines that load to a local duckdb instance. Switching to a different destination is trivial, all you need to do is change the destination parameter in capsule_crm_pipeline.py to postgres and supply the credentials as outlined in the destination doc linked below.
3. Running your pipeline for the first time
The dlt cli has also created a main pipeline script for you at capsule_crm_pipeline.py, as well as a folder capsule_crm that contains additional python files for your source. These files are your local copies which you can modify to fit your needs. In some cases you may find that you only need to do small changes to your pipelines or add some configurations, in other cases these files can serve as a working starting point for your code, but will need to be adjusted to do what you need them to do.
The main pipeline script will look something like this:
import dlt
from capsule_crm import capsule_crm_source
if __name__ == "__main__":
pipeline = dlt.pipeline(
pipeline_name="capsule_crm_pipeline",
destination='duckdb',
dataset_name="capsule_crm_data",
progress="log",
export_schema_path="schemas/export"
)
source = capsule_crm_source()
info = pipeline.run(source)
print(info)
Provided you have set up your credentials, you can run your pipeline like a regular python script with the following command:
python capsule_crm_pipeline.py
4. Inspecting your load result
You can now inspect the state of your pipeline with the dlt cli:
dlt pipeline capsule_crm_pipeline info
You can also use streamlit to inspect the contents of your PostgreSQL destination for this:
# install streamlit
pip install streamlit
# run the streamlit app for your pipeline with the dlt cli:
dlt pipeline capsule_crm_pipeline show
5. Next steps to get your pipeline running in production
One of the beauties of dlt is, that we are just a plain Python library, so you can run your pipeline in any environment that supports Python >= 3.8. We have a couple of helpers and guides in our docs to get you there:
The Deploy section will show you how to deploy your pipeline to
- Deploy with GitHub Actions: Learn how to set up your pipeline to run on GitHub Actions, a free CI/CD runner. Follow the guide here.
- Deploy with Airflow: Use Google Composer to manage your Airflow environment and deploy your pipeline. Detailed instructions can be found here.
- Deploy with Google Cloud Functions: Explore how to deploy your pipeline using Google Cloud Functions for a serverless experience. Check the guide here.
- Explore other deployment options: For more deployment methods and detailed walkthroughs, visit the comprehensive guide here.
The running in production section will teach you about:
- How to Monitor your pipeline: Learn how to monitor your
dltpipeline in production to ensure everything runs smoothly and to catch issues early. How to Monitor your pipeline - Set up alerts: Configure alerts for your
dltpipeline to get notified of any issues or important events. Set up alerts - And set up tracing: Implement tracing in your
dltpipeline to track the execution flow and diagnose problems effectively. And set up tracing
