Hi, We have an upcoming project which involves enhancements to an onsite product catalog, which now needs to communicate with Google Base. As products in the local catalog are changed, the changes must be replicated to a Google Base list. We need you to use the API for this. You are restricted to PHP4 and Curl for interaction due to server limitations. You will need to craft XML requests and parse XML results to make sure the correct items are updated. The code needs to be written quickly, but accurately. Your code needs to account for errors in authentication (including CAPTCHA responses for 'install applications'), insertions, updates and deletions. You may need to develop a caching mechanism so if there are failures, pending updates can be sent later. Each product in the catalog has a unique ID, so we would want to use that for the ID stored in Google Base. We need an experienced PHP developer for this, ideally someone how has worked with the Google Base API before. Please email us with a quote for this, your experience, examples of related work, your availability, etc. We look forward to hearing from you soon.
