How to use the API?
To get started with this API, you need to create an account with Abstract.
Upon successful registration, you need to log in and access your dashboard. To access the API, look out for Exchange rates under the Lookup category in the dashboard.
After clicking the Exchange rates option, you will get another screen where you will see your API key and some very useful sample codes on how to use the Exchange rate API. Let’s make a quick API call using Postman to get the live exchange rate of USD against over 150 countries' currencies.
To ensure a proper response from the API, make sure to replace the query parameter ‘api_key’ with the Abstract Key provided to you after signup.
Using Abstract Currency Exchange and Forex API with PHP
Let’s put the Currency Exchange and Forex API to some good use by creating a simple demo API in PHP.
To set up the PHP development and runtime environment, you can install XAMPP. Download and install the XAMPP package according to your operating system. Once the installation is finished, browse the installation path for Xampp and access the ‘htdocs’ subdirectory. This is the root directory containing the PHP code.
Create another subdirectory within ‘htdocs’, named ‘api’, and then create an empty file ‘live.php’ inside it. This will be the path for accessing the demo API for live currency rates.
The PHP Code for Getting Currency Rates
Open the file 'live.php' inside your favorite code editor and copy the following code.
Save the file and ensure that the placeholder “<Your_Abstract_key>” is replaced by your actual API key.
This demo API just acts as a PHP interface for the Currency Exchange and Forex API. It forwards the request from the API consumer to the Currency Exchange and Forex API and relays the response of Currency Exchange and Forex API back to the consumer. Internally it relies on the PHP curl library to invoke the Currency Exchange and Forex API.
To test the demo API, you need to run it within a web server. Run the default php server using the command ‘php -S localhost:8000’. Then you should be able to access this API via the URL ‘http://localhost:8000/api/live.php’.
This is the same API response that you got earlier for the Currency Exchange and Forex API. The only difference is that this time it is returned via the demo API written in PHP.
