Webhook Integration and Phone Verification through Nexmo


We need help building actions that happen once a user submits a form on an external site. These actions are outlined below:

[url removed, login to view] Webhooks to insert a record in our MySQL database

[url removed, login to view] Nexmo Verify API to send a verification code to the phone number provided as part of the form submission

[url removed, login to view] to a page which shows the phone number to which verification code was sent and has a textbox for the user user to enter that

[url removed, login to view] the verification code is incorrect, display an appropriate message to the user and allow to re-enter the code

[url removed, login to view] the verification code is correct, redirect to page showing a success message. Update the corresponding record (using phone number and date as the key) in MySQL database to indicate this


This needs to be built entirely in PHP. We have an existing WordPress site alongside which this will be hosted. Our hosting is a LAMP package. To verify phone number we will use Nexmo Verify API. We will provide the table structure for MySQL. All the code written needs to function flawlessly on our existing LAMP hosting.


Nexmo Verify API: [url removed, login to view]

Submission form: [url removed, login to view]

UnBounce: [url removed, login to view]

Milestones & Payment Schedule

Each of the steps defined in the Overview forms a milestone / distinct functionality of the overall request. Please be aware that we are unable to release payment in advance and will be defining two separate milestones as below:

1. 40% of payment to be released after full functionality is demonstrated on your test server or through a video call on your local machine

2. 30% of payment to be released after code is released and deployed on our hosting platform

3. 30% will be released after we have QA-ed and confirm the full functionality as requested

Other Details

Nexmo API token will be needed. Please use your own free token by creating an account on Nexmo

MySQL table structure will be provided. This will include all the form fields that UnBounce will post using Webhook

Important Requirements

[url removed, login to view] that the webhook request being sent is coming from 1 of the 2 specified IP addresses (provided by UnBounce and known in advance). Any other requests should be discarded

2. Perform an *update* instead of an *insert* if the form submission is identical to one submitted previously. This is determined by querying first for existing records based on date, category, phone and email - and if that returns 1 or more records, perform an update. In all other cases, perform an insert operation

[url removed, login to view] styling on the page is requested

[url removed, login to view] will be no URL parameters with form data. Everything should be collected through the webhook only

[url removed, login to view] error checking and logs needs to be maintained. We can create additional tables as needed for this

[url removed, login to view] needs adequate documentation and comments. Variables used need to be suitably named and need to be logical

[url removed, login to view] version or compatibility issues will need to be resolved. Alternately phrased, everything needs to function on our hosting environment. Please inquire in advance on all details you need in this regard
