Description
The Proof of Purchase module is designed to allow participants to demonstrate that they have completed an action by uploading an image (JPG/PNG, GIF, SVG) or a document (PDF). It can be used to confirm the following points:
Completing a purchase by uploading a photo of the receipt.
Ownership of an item by the user by providing an image of the item in question.
The presence of the user in a specific location by uploading a photo of themselves in the required situation.
Discovering a hidden clue in a store by a customer through the submission of a photo of the clue.
This module can be associated with various mechanics (instant wins, score-based games, drawings, etc.), but its activation depends on the validation of the submitted document as proof by a moderator. It is distinct from the Upload Media module due to its "protected page" system and the fact that it is not linked to the Media Gallery page. It proves to be particularly effective for achieving objectives such as "Drive-to-Store" or "Drive-to-Web."
Installation
To use this module, access the campaign editor and add a new page by clicking the "+" button and selecting it from the module list.
Page Design
Import your Desktop background by clicking on the "+" icon in the Background Image. You also have the option to add a solid background color that surrounds your page. You can leave the default color or choose to align your campaign with a color that reflects your brand or your game pages, for example.
Module Settings
Participation Limit: Define the number of participations per day, week, month, or campaign, and per user based on your expectations (single upload or multiple uploads), then create and select your "Already Played" page. If the user attempts to replay, they will be directed to this page. If the participation limit is disabled, participation is unlimited.
Protected Page: Define the page to which the user will arrive after validating their document upload. This page will contain native security measures preventing any user who has not uploaded from accessing it. However, you will need to verify the uploaded document by accessing the moderation screen and, if necessary, contact the participant if the document needs to be rejected.
Module Content
Add an upload: The module initially contains four upload buttons that need to be activated by clicking on them in the "Content" section.
Upload 1: corresponds to the upload button for a Barcode (JPG/PNG, GIF, PDF format - max 10 MB per upload).
Upload 2: corresponds to the upload button for an RIB (JPG/PNG, GIF, PDF format - max 10 MB per upload).
Upload 3: corresponds to the upload button for an Invoice (JPG/PNG, GIF, PDF format - max 10 MB per upload).
Upload 4: corresponds to a standard upload button (JPG/PNG, GIF, PDF format - max 10 MB per upload).
⚠️ File upload is limited to a maximum of 10 MB if you publish your campaign on a custom domain. If you publish on adbx.io, this limit is reduced to 2 MB.
Edit Error Text: Customize the text that is displayed if the user does not upload their proof of purchase correctly (file too large, wrong format).
