MS Dynamics CRM & WordPress integration

Hi,

I have an client who is looking to add a feature to their website and I am hoping someone here might be able to offer some advice.

They use MS Dynamics for their CRM and want to have a search feature on their website (self hosted Wordpress site) which pulls the information from their CRM and displays it on their site when a search is made.

Is this something which is possible and what would be the best way to go about this? Is there an API or a php bridge available? I know Zapier have something in the works but it is not available yet.

Ta heaps in advance for any help that can be provided
