Capture lead in WordPress site and verify using Nexmo API

We need help developing PHP code that integrates with our existing WordPress leads management platform and performs the below defined functionality. The scope of this project for the time being is limited to only writing the core PHP and MySQL code - and does not involve any styling or design work. Here’s an outline of what needs to be built: [login to view URL] and parse out a variable from the page URL. Example: [login to view URL]|456|7892|2332 - [login to view URL] parsing the above URL - you should have a list of vendorids. In the example above this would be 123, 456, 7892 and 2332. Connect to a MySQL database, retrieve the name of each vendor and display it on the page (just the name, vendorids are not needed) [login to view URL] the same page, display a form where user can enter name (text), description (text) and phone number (number in xxx-xxxx-xxxx format). Commit this record to an existing table after validating that all fields have input and that phone number is in the correct format [login to view URL] will now call existing code written for Nexmo API to send a verification code through a text message, to the number captured in Step 3. This functionality already exists and works fine - but will need to be integrated in our new workflow [login to view URL] is now redirected to a page where the verification code can be entered and confirmed using Nexmo API. If the code is correct a success message will be displayed - if incorrect, prompt the user to re-enter the verification code (screen is attached) [login to view URL] confirming that the code is correct, update the corresponding user’s record in MySQL, mark it as phone verified and redirect to a success page. This functionality also exists but may need to be modified to integrate with the new workflow Important a. We have a WordPress site to which you will integrate your pages / code. If you do not have experience doing this please do not bid on the project as it will likely not be completed b. You will be given access to the current code for phone verification using Nexmo API. It is challenging for me as a non-developer to estimate the amount of effort involved but believe its not complex given the similarities between our earlier workflow and the new one c. Your code needs to be adequately documented (commented) and needs to function with our existing hosting. If you have any queries in this regard please inquire prior to bidding / accepting the project. We use hosting from PHP hosting from [login to view URL] - details available here [login to view URL] d. Nexmo code provided to you is restricted to use on this project only. You confirm that it will not be utilized on any other work or given to someone else. All other code written as part of this project will only be exclusively provided to use and not to anyone else or used for any other purpose Payment / Milestones We regret not being able to provide any advance payment. a. The first milestone will be on completion and demonstration of Steps 1 to 3 on a screen share call. 20% of the payment can be released at this stage b. Completing steps 4 to 6 will be the 2nd milestone. Again, you will need to demonstrate this on screen share after which 35% of payment will be released c. 3rd milestone involves integration with our WordPress installation and deploying / testing on our hosting environment. This is the final milestone and accounts for the remaining 45% payment. Please bear in mind that we will need 3-5 days for final testing and acceptance before releasing the final installment
