Source implementation for Paypal Transaction.

Project description

Paypal-Transaction source connector

This is the repository for the Paypal-Transaction source connector, written in Python. For information about how to use this connector within Airbyte, see the documentation.

Local development

Prerequisites

  • Python (~=3.9)
  • Poetry (~=1.7) - installation instructions here
  • Paypal Client ID and Client Secret
  • If you are going to use the data generator scripts you need to setup yourPaypal Sandbox and a Buyer user in your sandbox, to simulate the data. YOu cna get that information in the Apps & Credentials page.
    • Buyer Username
    • Buyer Password
    • Payer ID (Account ID)

Installing the connector

From this connector directory, run:

poetry install --with dev

Create credentials

If you are a community contributor, follow the instructions in the documentation to generate the necessary credentials. Then create a file secrets/config.json conforming to the source_paypal_transaction/spec.yaml file. Note that any directory named secrets is gitignored across the entire Airbyte repo, so there is no danger of accidentally checking in sensitive information. See sample_files/sample_config.json for a sample config file.

  • You must have created your credentials under the secrets/ folder
  • For the read command, you can create separate catalogs to test the streams individually. All catalogs are under the folder integration_tests. Select the one you want to test with the read command.

Locally running the connector

poetry run source-paypal-transaction spec
poetry run source-paypal-transaction check --config secrets/config.json
poetry run source-paypal-transaction discover --config secrets/config.json
# Example with list_payments catalog and the debug flag
poetry run source-paypal-transaction read --config secrets/config.json --catalog integration_tests/configured_catalog_list_payments.json --debug

Running unit tests

To run unit tests locally, from the connector directory run:

poetry run pytest unit_tests

Building the docker image

  1. Install airbyte-ci
  2. Run the following command to build the docker image:

Installing the connector

From this connector directory, run:

poetry install --with dev
Customizing our build process

When contributing on our connector you might need to customize the build process to add a system dependency or set an env var. You can customize our build process by adding a build_customization.py module to your connector. This module should contain a pre_connector_install and post_connector_install async function that will mutate the base image and the connector container respectively. It will be imported at runtime by our build process and the functions will be called if they exist.

Here is an example of a build_customization.py module:

from __future__ import annotations

from typing import TYPE_CHECKING

if TYPE_CHECKING:
    # Feel free to check the dagger documentation for more information on the Container object and its methods.
    # https://dagger-io.readthedocs.io/en/sdk-python-v0.6.4/
    from dagger import Container

An image will be available on your host with the tag airbyte/source-paypal-transaction:dev.

Running as a docker container

Then run any of the connector commands as follows:

docker run --rm airbyte/source-paypal-transaction:dev spec
docker run --rm -v $(pwd)/secrets:/secrets airbyte/source-paypal-transaction:dev check --config /secrets/config.json
docker run --rm -v $(pwd)/secrets:/secrets airbyte/source-paypal-transaction:dev discover --config /secrets/config.json
docker run --rm -v $(pwd)/secrets:/secrets -v $(pwd)/integration_tests:/integration_tests airbyte/source-paypal-transaction:dev read --config /secrets/config.json --catalog /integration_tests/configured_catalog.json

Running our CI test suite

You can run our full test suite locally using airbyte-ci:

airbyte-ci connectors --name=source-paypal-transaction test

If you are testing locally, you can use your local credentials (config.json file) by using --use-local-secrets

airbyte-ci connectors --name source-paypal-transaction --use-local-secrets test

Customizing acceptance Tests

Customize acceptance-test-config.yml file to configure acceptance tests. See Connector Acceptance Tests for more information. If your connector requires to create or destroy resources for use during acceptance tests create fixtures for it and place them inside integration_tests/acceptance.py.

Running Unit tests locally

To run unit tests locally, form the root source_paypal_transaction directory run:

python -m pytest unit_test

Test changes in the sandbox

If you have a Paypal Sandbox you will be able to use some APIs to create new data and test how data is being created in your destinaiton and choose the best syn strategy that suits better your use case. Some endpoints will require special permissions on the sandbox to update and change some values.

In the bin folder you will find several data generator scripts:

  • disputes_generator.py:

    • Update dispute: Uses the PATCH method of the https://api-m.paypal.com/v1/customer/disputes/{dispute_id} endpoint. You need the ID and create a payload to pass it as an argument. See more information here.
    python disputes_generator.py update DISPUTE_ID ''[{"op": "replace", "path": "/reason", "value": "The new reason"}]'
    
    • Update Evidence status: Uses the POST method of the https://api-m.paypal.com/v1/customer/disputes/{dispute_id}/require-evidence endpoint. You need the ID and select an option to pass it as an argument. See more information here
    python update_dispute.py require-evidence DISPUTE_ID SELLER_EVIDENCE
    
  • invoices.py:

    • Create draft invoice: Uses the POST method of the https://api-m.sandbox.paypal.com/v2/invoicing/invoices endpoint. It will automatically generate an invoice (no need to pass any parameters). See more information here.
    python invoices.py create_draft
    
    • Send a Draft Invoice: Uses the POST method of the https://api-m.sandbox.paypal.com/v2/invoicing/invoices/{invoice_id}/send endpoint. You need the Invoice ID, a subject and a note (just to have something to update) and an email as an argument. See more information here
    python invoices.py send_draft --invoice_id "INV2-XXXX-XXXX-XXXX-XXXX" --subject "Your Invoice Subject" --note "Your custom note" --additional_recipients example@email.com
    
  • payments_generator.py:

    • Partially update payment: Uses the PATCH method of the https://api-m.paypal.com/v1/payments/payment/{payment_id} endpoint. You need the payment ID and a payload with new values. (no need to pass any parameters). See more information here.
     python script_name.py update PAYMENT_ID '[{"op": "replace", "path": "/transactions/0/amount", "value": {"total": "50.00", "currency": "USD"}}]'
    
  • paypal_transaction_generator.py: Make sure you have the buyer_username, buyer_password and payer_id in your config file. You can get the sample configuratin in the sample_config.json.

    • Generate transactions: This uses Selenium, so you will be prompted to your account to simulate the complete transaction flow. You can add a number at the end of the command to do more than one transaction. By default the script runs 3 transactions.

    NOTE: Be midnfu of the number of transactions, as it will be interacting with your machine, and you may not be able to use it while creating the transactions

     python paypal_transaction_generator.py [NUMBER_OF_DESIRED_TRANSACTIONS]
    
  • product_catalog.py:

    • Create a product: Uses the POST method of the https://api-m.sandbox.paypal.com/v1/catalogs/products endpoint. You need to add the description and the category in the command line. For the proper category see more information here.
    python product_catalog.py --action create --description "YOUR DESCRIPTION" --category PAYPAL_CATEGORY
    
    • Update a product: Uses the PATCH method of the https://developer.paypal.com/docs/api/catalog-products/v1/#products_patch endpoint. You need the product ID, a description and the Category as an argument. See more information here
    python product_catalog.py --action update --product_id PRODUCT_ID --update_payload '[{"op": "replace", "path": "/description", "value": "My Update. Does it changes it?"}]'
    

Dependency Management

All of your dependencies should go in setup.py, NOT requirements.txt. The requirements file is only used to connect internal Airbyte dependencies in the monorepo for local development. We split dependencies between two groups, dependencies that are:

  • required for your connector to work need to go to MAIN_REQUIREMENTS list.
  • required for the testing need to go to TEST_REQUIREMENTS list

All of your dependencies should be managed via Poetry.

To add a new dependency, run:

poetry add <package-name>

Please commit the changes to pyproject.toml and poetry.lock files.

Publishing a new version of the connector

You've checked out the repo, implemented a million dollar feature, and you're ready to share your changes with the world. Now what?

  1. Make sure your changes are passing our test suite: airbyte-ci connectors --name=source-paypal-transaction test
  2. Bump the connector version (please follow semantic versioning for connectors):
    • bump the dockerImageTag value in in metadata.yaml
    • bump the version value in pyproject.toml
  3. Make sure the metadata.yaml content is up to date.
  4. Make sure the connector documentation and its changelog is up to date (docs/integrations/sources/paypal-transaction.md).
  5. Create a Pull Request: use our PR naming conventions.
  6. Pat yourself on the back for being an awesome contributor.
  7. Someone from Airbyte will take a look at your PR and iterate with you to merge it into master.
  8. Once your PR is merged, the new version of the connector will be automatically published to Docker Hub and our connector registry.
