Vouchers.Im API

This service is being discontinued from May 1st, 2011. No new subscriptions accepted.

Vouchers.I'm API (or "Application Programmatic Interface" or Web Service) gives you access to our open database of vouchers and discount codes. Our API has a simple REST interface which transmits data over HTTP using GET requests. Results are returned in the body of the HTTP response in XML format.


We are meticulously building our voucher codes database to contain all existing vouchers available. We carefully rewrite voucher descriptions to be short, informative and precise. All vouchers in our database adhere to standardized format to be easily displayed, processed and distributed:

<details>25% discount on selected Landline Telephones</details>

We would love to hear from you in general, if you have any thoughts on Vouchers.Im and our voucher codes API, any feedback or suggestions what you'd like to see in our web service or how it can be improved. Please use contact us page to get in touch.

Access Levels

We offer two access levels for using the API.

Free access:

You are allocated 200 api units per day to be used for any API call with just one restriction: you can not execute call to list fresh vouchers (those added in the last 5 days). These same vouchers, however, can be found and listed with other API calls.

Premium access:

You are allocated 1500 api units per day which you can use for any API call without restrictions.
Subscription cost for Premium access is £50 per month.
Premium access is provided on a per site basis; if you publish voucher codes on more than one website you must obtain another API key for this purpose.
