WhatsApp Bot Payment Integration with Paystack

I've developed a WhatsApp bot for a document printing service. It currently facilitates document uploads and custom print settings. I now need an expert to integrate Paystack into this bot for automated payment processing.

Key Features of the Current Bot:
- Document Upload: Allows customers to upload PDFs, Word documents, and images (JPEG/PNG).
- Print Settings: Users can specify preferences such as color vs. black & white, paper sizes (A4 or A3), and the number of copies.

Required Integration with Paystack:
- Payment Link Generation: Users should be able to generate a payment link within the bot.
- Transaction Verification: Successful transactions need to be automatically verified through the API before documents are sent for printing.
- Payment Confirmation: Users should receive payment confirmation receipts via WhatsApp.

Ideal Skills and Experience:
- Proficiency in integrating payment gateways, specifically Paystack.
- Extensive experience with WhatsApp bot development.
- Strong understanding of API usage for transaction verification.
- Ability to create interactive elements like clickable buttons within chat interfaces.
