Seemingly random 403 responses on SearchCompanies

Hi,

We are in testing with the CompaniesHouse API but we seem to get random 403 errors on GET requests for searching companies. The 403s happen in ~3 second bursts with no obvious pattern of occurrences.

We are a large company so there is a chance that we are calling from several IP addresses, but we have no IP whitelisting so I can’t think that of being a problem.

Here is an example of a pattern of failures:

• 2019-10-21 16:29:03.000
• 2019-10-21 16:29:01.000
• 2019-10-21 16:29:00.000

Is there anything obvious to you that may be the problem? I couldn’t find anything else on the forum which seemed like the same issue. I’m happy to give more information via email.

Thank you in advance,

Dylan B
