You have chosen to sponsor your bid up to a maximum amount of .
I want a Python program that I can deploy to Google App Engine that is similar in functionality to http://www.donationstracker.com/ (but only needs to support a single Paypal account, so no login/credentials etc. as that can be set in the code).
That is, provides a persistent server that accepts IPN messages from PayPal and increments a 'total', then serves an automatically generated donation meter image when a specific URL is requested. Although only one PayPal account needs to be supported, it should have the ability to accept an optional field in some way to sort the donation into a separate bucket.
The result should be that I could go to a url like:
and it would serve a png based on how many donations had been received for 'campaign1'.
Note that the image should be cached (i.e. it should only regenerate in response to an IPN message, not in response to a jpeg request).
- I will not pay more than $60, and this project has a hard deadline of 5 August, so please bid accordingly.
- I would prefer you to use webapp2 or flask
