How to Implement a Phone Number Reverse Lookup API into Your Website
Implementing a phone number reverse lookup API into your website involves a few essential steps. Here we are using Numverify as a reference to provide the steps:
1. Sign up and obtain an API key
Visit the Numverify website and sign up for an account. Once registered, you will receive an API key that you will use to authenticate your API requests.
| http://apilayer.net/api/validate?access_key=YOUR_ACCESS_KEY |
2. Choose an integration method
NumVerify provides various integration methods to suit your application’s needs, including JavaScript, PHP, Python, and more. Select the integration method that aligns with your development environment and programming language.
3. Construct the API request
Determine the endpoint URL for the Numverify API and construct your API request. Typically, the endpoint will include the base URL followed by the phone number you want to verify.
| http://apilayer.net/api/validate ? access_key = YOUR_ACCESS_KEY & number = 14158586273 |
4. Include authentication
Add your API key as an authentication parameter in your API request. This step ensures that your requests are properly authorized.
Optional Parameter:
| country_code specify a country code if you intend to use a national phone number for your request format set to “1” in order to request prettified JSON result set (use only for debugging!) callback append your preferred JSONP callback function name. (See “JSONP Callbacks” section) |
5. Send the API request
Use your chosen programming language’s appropriate method or function to send the API request to the Numverify server. Ensure that you capture the response returned by the API.
| Object | Description |
| “valid” | Returns true if the specified phone number is valid. |
| “number” | Returns the phone number you specified in a clean format. (stripped of any special characters) |
| “local_format” | Returns the local (national) format of the specified phone number. |
| “international_format” | Returns the international format of the specified phone number. |
