There are a few ways to contribute, which we'll enumerate below:

Feature Request

If you'd like to make a feature request, please read this section.

The GitHub issue tracker is the preferred channel for library feature requests, but please respect the following restrictions:

• Please search for existing issues in order to ensure we don't have duplicate bugs/feature requests.
• Please be respectful and considerate of others when commenting on issues

Submit a Bug Report

Note: DO NOT include your credentials in ANY code examples, descriptions, or media you make public.

A software bug is a demonstrable issue in the code base. In order for us to diagnose the issue and respond as quickly as possible, please add as much detail as possible into your bug report.

Before you decide to create a new issue, please try the following:

1. Check the GitHub issues tab if the identified issue has already been reported, if so, please add a +1 to the existing post.
2. Update to the latest version of this code and check if the issue has already been fixed
3. Copy and fill in the Bug Report Template we have provided below

Please use our Bug Report Template

In order to make the process easier, we've included a sample bug report template.

Improvements to the Codebase

We welcome direct contributions to the sendgrid-python code base. Thank you!

Development Environment

Prerequisites

• Python version 2.7, 3.5, 3.6, 3.7, or 3.8
• python_http_client
• ecdsa_python
• pyenv
• tox

Initial setup

git clone https://github.com/sendgrid/sendgrid-python.git
cd sendgrid-python

Environment Variables

First, get your free Twilio SendGrid account here.

Next, update your environment with your SENDGRID_API_KEY.

cp .env_sample .env

Then edit .env and insert your API key.

# You do not need to do this when using Docker Compose
source .env

Execute

See the examples folder to get started quickly.

If testing from the root directory of this repo, create a new file (e.g. test.py) and replace import sendgrid with from sendgrid import *

Understanding the Code Base

• /examples
  • Working examples that demonstrate usage.
• /tests
  • Currently, we have unit and profiling tests.
• /sendgrid
  • The Web API v3 client is sendgrid.py, the other files are legacy code for our mail send v2 endpoint.

Testing

The PR must pass all the tests before it is reviewed.

All test files are in the test directory. For the purposes of contributing to this repo, please update the test_sendgrid.py file with unit tests as you modify the code.

The integration tests require a Twilio SendGrid mock API in order to execute. We've simplified setting this up using Docker to run the tests. You will just need Docker Desktop and make.

Once these are available, simply execute the Docker test target to run all tests: make test-docker. This command can also be used to open an interactive shell into the container where this library is installed. To start a bash shell for example, use this command: command=bash make test-docker.

Style Guidelines & Naming Conventions

Generally, we follow the style guidelines as suggested by the official language. However, we ask that you conform to the styles that already exist in the library. If you wish to deviate, please explain your reasoning.

• PEP8

Please run your code through:

• pyflakes
• pylint
• pep8

Creating a Pull Request

1. Fork the project, clone your fork, and configure the remotes:

   # Clone your fork of the repo into the current directory
   git clone https://github.com/sendgrid/sendgrid-python
   
   # Navigate to the newly cloned directory
   cd sendgrid-python
   
   # Assign the original repo to a remote called "upstream"
   git remote add upstream https://github.com/sendgrid/sendgrid-python

2. If you cloned a while ago, get the latest changes from upstream:

   git checkout <dev-branch>
   git pull upstream <dev-branch>

3. Create a new topic branch (of the main project development branch) to contain your feature, change, or fix:

   git checkout -b <topic-branch-name>

4. Commit your changes in logical chunks. Please adhere to these git commit message guidelines or your code is unlikely to be merged into the main project. Use Git's interactive rebase feature to tidy up your commits before making them public.

4a. Create tests.

4b. Create or update the example code that demonstrates the functionality of this change to the code.

5. Locally merge (or rebase) the upstream development branch into your topic branch:

   git pull [--rebase] upstream main

6. Push your topic branch up to your fork:

   git push origin <topic-branch-name>

7. Open a Pull Request with a clear title and description against the main branch. All tests must be passing before we will review the PR.

Code Reviews

If you can, please look at open PRs and review them. Give feedback and help us merge these PRs much faster! If you don't know how, GitHub has some great information on how to review a Pull Request.
