### Deploying the Function with doctl (Bash)

Source: https://github.com/digitalocean/sample-functions-python-sendgrid-email/blob/main/README.md

Deploys the sample function to your DigitalOcean App Platform using the `doctl` CLI. The `--remote-build` flag ensures the build happens in the cloud environment.

```bash
doctl serverless deploy sample-functions-python-sendgrid-email --remote-build
```

--------------------------------

### Cloning the Sample Function Repository (Bash)

Source: https://github.com/digitalocean/sample-functions-python-sendgrid-email/blob/main/README.md

Clones the sample Python Sendgrid email function repository from GitHub to your local machine. This is the first step before deploying the function.

```bash
git clone git@github.com:digitalocean/sample-functions-python-sendgrid-email.git
```

--------------------------------

### Invoking the Function with doctl (Bash)

Source: https://github.com/digitalocean/sample-functions-python-sendgrid-email/blob/main/README.md

Invokes the deployed serverless function using the `doctl` CLI, passing email parameters (`from`, `to`, `subject`, `content`) as payload.

```bash

```

--------------------------------

### Specify SendGrid Dependency (Python)

Source: https://github.com/digitalocean/sample-functions-python-sendgrid-email/blob/main/packages/sample/emails/requirements.txt

This line specifies the required 'sendgrid' package and its exact version (6.4.6) for the project. This is typically found in a 'requirements.txt' file used by package managers like pip to ensure reproducible builds.

```Python
sendgrid==6.4.6
```

--------------------------------

### Invoking the Function with curl (Bash)

Source: https://github.com/digitalocean/sample-functions-python-sendgrid-email/blob/main/README.md

Invokes the deployed serverless function via an HTTP PUT request using `curl`. The email parameters are passed in the request body as JSON.

```bash
