Sendgrid Template Management

SendGrid Template Management

This skill implements functionality for managing email templates using the SendGrid API, allowing users to create, modify, and delete templates efficiently.

TL;DR Checklist

• Ensure all template IDs are valid before operations.
• Provide clear success messages on all template operations.
• Handle errors with descriptive messages for invalid operations.
• Validate input parameters to prevent runtime errors.
• Implement rate limiting and error handling for API calls.

When to Use

Use this skill when:

• You need to automate the creation of email marketing templates.
• You want to update existing templates dynamically based on user feedback.
• You need to delete old or unused templates to keep your template list organized.

Core Workflow

1. Create Template: Validate input data for new templates and call SendGrid API to create them.

   • Checkpoint: Ensure template ID is generated and returned successfully.

2. Update Template: Validate existing template ID and new content, then update the template via the API.

   • Checkpoint: Ensure update response confirms success.

3. Delete Template: Validate the existing template ID and make a delete request to SendGrid.

   • Checkpoint: Ensure successful deletion confirmation message.

Implementation Patterns

Pattern 1: Creating a Template

import os
from sendgrid import SendGridAPIClient
from sendgrid.helpers.mail import Mail

def create_template(template_name: str, html_content: str) -> dict:
    """Create a new email template using SendGrid API."""
    sg = SendGridAPIClient(os.environ.get("SENDGRID_API_KEY"))
    template_data = {
        "name": template_name,
        "html_content": html_content
    }
    response = sg.client.templates.post(request_body=template_data)
    if response.status_code == 201:
        return response.to_dict()
    else:
        raise Exception(f"Failed to create template: {response.body}")

Pattern 2: Updating a Template

def update_template(template_id: str, new_content: str) -> bool:
    """Update an existing template with new content."""
    sg = SendGridAPIClient(os.environ.get("SENDGRID_API_KEY"))
    update_data = {
        "html_content": new_content
    }
    response = sg.client.templates.template_id(template_id).patch(request_body=update_data)
    return response.status_code == 200

Pattern 3: Deleting a Template

def delete_template(template_id: str) -> bool:
    """Delete an email template based on its ID."""
    sg = SendGridAPIClient(os.environ.get("SENDGRID_API_KEY"))
    response = sg.client.templates.template_id(template_id).delete()
    return response.status_code == 204

Constraints

MUST DO

• Validate template IDs before conducting create/update/delete operations (Early Exit).
• Return success messages or confirmations after each operation.
• Implement error handling to provide descriptive messages for failures (Fail Fast).

MUST NOT DO

• Mutate input parameters directly; always create new data structures based on inputs.
• Allow empty or invalid template data to reach the SendGrid API.
