Software to change Pinterest Source URL's

Primary Function ================ Software that will search all existing created pins (not "repins", which are also known as "saves") in a Pinterest account for all those where the domain of the source URL matches the domain entered, and then automatically change the source URL of those pins to use a new domain also entered. The software should have two user input fields; one for the OLD domain, and one for the NEW domain. Both fields must be entered (neither can be left blank). The format of the domain for both input boxes could be any of the following: [login to view URL] [login to view URL] [login to view URL] The software should change the domain element ONLY but retain the page element of the old URL when setting the new URL. For example: Say I have a Pinterest account with 10,000 pins. And those pins had any of the follwing source URL's: [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] And let's say I wanted to change the domain [login to view URL] to thisdecorsite.com. I would enter [login to view URL] in the OLD domain input box. And enter [login to view URL] in the NEW domain input box. The software would then search all 10,000 pins and do the following: Change all pins with a source URL of [login to view URL] to [login to view URL] Change all pins with a source URL of [login to view URL] to [login to view URL] Change all pins with a source URL of [login to view URL] to [login to view URL] It would NOT change any pins that have a source URL of [login to view URL] or [login to view URL] since the domain element does not match that entered. Software Platform ================= My preference is for software that will run on a Windows based PC. But software that will run on a Linux based web hosting server (i.e. written in php or similar code available as standard on a typical web hosting server) is acceptable. Support Unlimited Number of Pins ================================ The software must be able to perform the primary function on all pins in an account. There could be anywhere between 1,000-100,000+ pins in a Pinterest account. If the software cannot process such volumes of pins without interruption, then it must be able to be paused, but then restart from the point at which it was paused repeatedly until all pins have been processed. Support Unlimited Different Pinterest Accounts ============================================== The software must be able to perform the primary function on different pinterest accounts, but only one at any time. Support for Unlimited IP Proxies ================================ Some Pinterest accounts will have an associated IP proxy, but some will not. The software should have a user input field for a proxy, but the field is allowed to be left blank. If entered by the user, the software must use the correct IP proxy for all functions when working with a given Pinterest account. Possible Solution Via Pinterest API =================================== I strongly recommend you review the Pinterest API, as I believe this may be a solution to achieiving what I have outlined above. But I am not a software developer so leave it to you to determine whether the API can be used or not. Pinterest API information can be found at [login to view URL] Deliverables ============ Executable software that will perform as described above. Source code of the software.
