Simple PHP code to add a subscriber to MailPoe t(WordPress) mailing list using MailPoet's existing API

MailPoet is a commonly used mailing list service for WordPress. They have a very simple API. I have subscriber data that I will format as JSON that I want to POST using curly to the MailPoet API.

I you to adapt the MailPoet API to a standalone PHP file that I can post to with JSON as cURL data containing:
- subscriber first name
- subscriber last name
- subscriber email
- 2 custom fields (API supports this already)
- Mailpoet List ID
- 3 optional parameters (already supported by API)
- send_confirmation_email
- schedule_welcome_email
- and skip_subscriber_notification
- whatever user/security parameters MailPoet requires – if required, security can be in the curl header used for the posting.

This is a very simple project for someone who has worked with APIs, JSON, cURL, and PHP. I suspect this is 1-2 hours, including debug. I will provide a dev site and JSON file for your development. Target price <$100
