Promotion code validation apparatus and method
A method including interacting with a promotion code provider programmatically, providing a promotion code to a validation function of the promotion code provider, and evaluating a response from the promotion code provider. The act of interacting with a promotion code provider can include controlling an interface that simulates user actions, such as but not limited to controlling an in-memory web browser through an API, where the API provides a set of functions for simulating user actions. Accordingly, the method can be used to quickly and easily determine whether one or more promotion codes, such as online coupons, are valid.
1. A tangible, non-transitory, machine-readable medium storing instructions that when executed by one or more processors effectuate operations comprising:
determining, with a computer, by a validation driver executing on the computer and configured to at least partially control a web browser also executing on the computer, how to submit coupon codes to a first merchant website by:
accessing a previously specified characterization of one or more paths through the first merchant website in response to the web browser navigating to the first merchant website;
detecting a checkout webpage of the first merchant website by, for each of a plurality of webpages of the first merchant website, determining whether the respective webpage is the checkout webpage based on the previously specified characterization of one or more paths through the first merchant website; and
identifying a first coupon-code submission interface of the first merchant website, wherein the first coupon-code submission interface comprises a text-box input of the checkout webpage and a submit button of the checkout webpage, and identifying the first coupon-code submission interface comprises, for each of a plurality of elements of a document object model of the checkout webpage, determining whether the respective element is a coupon-code input text box based on how close the respective element is to another element of the document object model,
wherein the validation driver at least partially controls the web browser via a first application program interface by which the validation driver causes the web browser to simulate user actions;
receiving, with the computer, by the validation driver, from executing software configured to assign different batches of coupon codes to different validation drivers, a first batch of coupon codes having a plurality of coupon codes corresponding to the first merchant website and to be tested by the validation driver;
after detecting the checkout webpage of the first merchant website, testing, with the computer, by the validation driver, whether each of at least a plurality of the received first batch of coupon codes is valid by submitting coupon codes via the first coupon-code submission interface and parsing and interpreting responses of the first merchant website to submissions of coupon codes;
storing, with the computer, first test results indicating which tested coupon codes among the first batch are valid;
determining, with the computer, by the validation driver executing on the computer, how to submit coupon codes to a second merchant website by identifying a second coupon-code submission interface of the second merchant website, wherein:
the second coupon-code submission interface is a second application program interface exposed by the second merchant, the second application program interface being different from the first application program interface, and
the second application program interface provides access to a coupon validation function; and
testing, with the computer, by the validation driver, whether each of at least a plurality of the received second batch of coupon codes is valid by submitting coupon codes via the second application program interface and parsing and interpreting responses of the second application program interface to submissions of coupon codes; and
storing, with the computer, second test results indicating which tested coupon codes among the second batch are valid, wherein:
the first merchant websites and the second application program interface use different terminology in responses to coupon code submissions to indicate whether coupon codes are valid.
2. The medium of claim 1 , wherein:
the different terminology is interpreted with steps for evaluating responses received from promotion code providers after promotion codes have been submitted.
3. The medium of claim 1 , wherein:
simulating user actions comprises steps for controlling an interface that simulates user actions.
4. The medium of claim 1 , wherein:
the validation driver is configured to cause a JSON object containing validation data to be passed between components.
5. The medium of claim 1 , wherein:
the validation driver is configured to detect changes in webpages relative to previous versions of webpages.
6. The medium of claim 1 , wherein:
the web browser is an in-memory web browser.
7. The medium of claim 1 , wherein the operations further comprise:
limiting coupon validation testing based on a throttling pattern and historical testing rate data.
8. The medium of claim 1 , wherein:
the operations comprise sending the first and second test results to the executing software; and
the executing software is configured to evaluate the first and second test results and based on the evaluation configuring a subsequent batch of coupon-codes to be tested.
9. The medium of claim 1 , wherein testing whether each of at least a plurality of the received first batch of coupon codes is valid comprises:
steps for evaluating a response from a coupon-code provider.
10. The medium of claim 1 , wherein:
the validity driver is configured to automatically test the validity of coupon codes and only deliver online shoppers coupon codes that a merchant will accept.
11. A method, comprising:
determining, with a computer, by a validation driver executing on the computer and configured to at least partially control a web browser also executing on the computer, how to submit coupon codes to a first merchant website by:
accessing a previously specified characterization of one or more paths through the first merchant website in response to the web browser navigating to the first merchant website;
detecting a checkout webpage of the first merchant website by, for each of a plurality of webpages of the first merchant website, determining whether the respective webpage is the checkout webpage based on the previously specified characterization of one or more paths through the first merchant website; and
identifying a first coupon-code submission interface of the first merchant website, wherein the first coupon-code submission interface comprises a text-box input of the checkout webpage and a submit button of the checkout webpage, and identifying the first coupon-code submission interface comprises, for each of a plurality of elements of a document object model of the checkout webpage, determining whether the respective element is a coupon-code input text box based on how close the respective element is to another element of the document object model,
wherein the validation driver at least partially controls the web browser via a first application program interface by which the validation driver causes the web browser to simulate user actions;
receiving, with the computer, by the validation driver, from executing software configured to assign different batches of coupon codes to different validation drivers, a first batch of coupon codes having a plurality of coupon codes corresponding to the first merchant website and to be tested by the validation driver;
after detecting the checkout webpage of the first merchant website, testing, with the computer, by the validation driver, whether each of at least a plurality of the received first batch of coupon codes is valid by submitting coupon codes via the first coupon-code submission interface and parsing and interpreting responses of the first merchant website to submissions of coupon codes;
storing, with the computer, first test results indicating which tested coupon codes among the first batch are valid;
determining, with the computer, by the validation driver executing on the computer, how to submit coupon codes to a second merchant website by identifying a second coupon-code submission interface of the second merchant website, wherein:
the second coupon-code submission interface is a second application program interface exposed by the second merchant, the second application program interface being different from the first application program interface, and
