Made4China-Service-B-V Hi Made4China Service,
We're trying to help you step-by-step, it would be very useful if you would try the steps as proposed such that we can help you pinpoint the problem hopefully. Can you just ensure that the snippet made by Bastiaan runs? Then we know that it is not some weird local thing.
Or can you maybe share some of the code (without API keys or other sensitive data obviously) such that we can take a look? Your last messages seem translated automatically; it's not really helping I'm afraid, hence I will stick to English. We need to know what steps you've already tried. 🙂 From the "Dutch" error message I get the impression that this might also be a problem with the signing process of the request.
