PHP Script Integration with DocuSign API

I need a PHP script that integrates with the DocuSign REST API (sandbox environment) to automate the sending and signing of employment-related documents such as employment agreements or offer letters. The script should: Key Requirements: - Accept recipient details (name and email) and document type. - Read and encode a local PDF file. - Create and send a DocuSign envelope to the recipient for signature. - Generate an embedded signing URL that can be used within a web portal - Use OAuth - Be modular enough to handle multiple document types (e.g., offer letter vs. employment agreement). Please note, the functionality to be implemented in the PHP script includes: - Sending documents for signing - Receiving signed documents - Tracking document status Make sure to include relevant past projects in your proposal. I am looking for a freelancer who can deliver high-quality work in a timely manner.
