I work for a large organisation that requires to undertake a significant number of checks on companies house each day (I believe it is thousands per day).
From time to time we have issues on the website where a 403 Forbidden HTML response is received. Out IT teams are having dialogue with companies house about this - I believe there is a restriction on our IP address making calls to the website.
I have created a simple application to check companies status which due to volumes I am utilising the companies house API. I have set up the call so it stops if it breaches the 600 limit per 5 minutes of API calls and can then be ran again a few minutes later to continue from where it stopped. When running this I found that the beta search website was returning a 403 restricted response to all users in our organisation (single IP address I assume).
What I wanted to get confirmation on is would putting volumes through the API impact 403 restrictions on the website? The calls will be originating from our same API but obviously calling slightly different address for the companies house service.
