Is it possible to upload information to third-party sites?

Question

CMS

Good afternoon.
The crux of the matter, I am the administrator of the real estate site. I place apartments, update prices. It became necessary for the management to post information on third-party sites, such as Avito, yule, etc. The
question is how can you automate the uploading of information to sites if there is no sites api? Advise what books to read, it's very dreary to do the same thing. Laziness is the engine of progress.

Answer 1

Avito, Cyan, MLSN and other real estate aggregators have personal accounts for corporate clients and have their own feed formats. Those. you generate xml files on your site with a list of your objects according to the format of aggregators and regularly update this file by cron. Then, in the personal account of the corresponding aggregator, specify the path to the file.
