FAQ
Why choose FastAPI over Flask or Django for a contact form?
FastAPI is fast, reliable, and designed for modern APIs. It handles multiple form submissions efficiently and includes built-in data validation, which helps keep your contact form secure and stable in real-world usage.
What information do you need before starting the order?
To start, I need: 1. The form fields you want (name, email, message, etc.). 2. The recipient email address 3. Active email credentials (SMTP or ESP API key). 4. Your website domain for secure API access (CORS setup). Providing these upfront helps avoid delays.
Which spam protection should I choose: reCAPTCHA v3 or Honeypot?
Honeypot is invisible and works well for basic spam while keeping the form simple for users. reCAPTCHA v3 offers stronger protection against advanced bots but may slightly affect conversions. I can help you choose the best option based on your site.
Who provides the email sending credentials?
You provide the email service credentials (SMTP or ESP like SendGrid or Mailgun). I securely integrate them into the FastAPI backend using environment variables.
Will my emails go to spam?
Email delivery depends on proper domain setup. The API sends authenticated emails, but you must configure your domain’s SPF, DKIM, and DMARC records. This helps ensure messages reach the inbox instead of spam.
Who owns the code after delivery?
You receive full ownership and intellectual property rights to the delivered code after successful payment, according to Fiverr’s Terms of Service.
How do you connect the API with my website (WordPress, HTML, React)?
The service delivers a standalone API endpoint. I provide a simple JavaScript example that sends form data from your website to the API. This works with WordPress, static HTML, React, and similar platforms.
How long does delivery take?
Delivery time depends on the selected package and how quickly required details are provided. Faster delivery is available as a Gig Extra if you have a tight deadline.
Do you provide support after delivery?
Yes. I provide 7 days of free support to fix any issues related to the delivered code. Ongoing support or new features can be added through an extra or custom order.
Can submissions be saved to a database?
Yes. Database storage (PostgreSQL or MongoDB) is an advanced feature and is available in higher packages or via a custom offer.
