FAQ
Do I need to share my platform API keys or credentials?
Yes, I will need access or API keys for your CRM and email marketing platform to test and deploy the endpoints securely. All credentials are strictly kept confidential and destroyed upon project completion.
Can you build a custom API integration without Zapier or Make?
Absolutely. I specialize in native PHP, Laravel, REST APIs, and cURL scripts that run directly on your server without recurring monthly third-party software fees.
Can you handle custom database syncs (MySQL/PostgreSQL)?
Yes! I can write automated scripts to sync new database rows directly to your Mailchimp or ActiveCampaign contact lists in real time.
