Legal procedure to collect business information for website

1) If the information you seek is already in  the public domain - their address, website, e-mail id, business activity etc. you do not need any authorisation except a disclaimer that information taken from public sources and is not verified..

2) If you seek to publish information not publicly available - names and cell phone numbers of their Key Management personnel, for example, then you should ask such information and authorisation to publish the same from the Owner / Managing director of the Company.
