What our customers think

Your API integrates like poetry and it's absolutely perfect for our business requirements. I first tested with the testing API using your supplied documentation, to check the connection code, which worked fine. I then tested the full XML file to check to code which reads the file, which worked fine! So I'm happy to now put these two pieces together and get it all integrated. I cant believe how easy it is to integrate with, and matches our requirements 100%.

We'd tried out a number of API or integration services, but the Company Check system stood out for us. It's easy to use, the Company Check team have been nothing but helpful and have always been on hand to respond to our questions. We were given a tailored service and continue to receive it; we couldn't recommend their API enough.
