API Rate Limit (RateExceededError)

Hello,

Our application was running just fine up until yesterday but since then we started getting the following message over and over:

Message: [RateExceededError <rateName=RATE_LIMIT, rateKey=null, rateScope=ACCOUNT, retryAfterSeconds=30>]

Errors:

Error [1]:

field_path:

trigger:

error_string: RateExceededError.RATE_EXCEEDED

api_error_type: RateExceededError

reason: RATE_EXCEEDED

rate_name: RATE_LIMIT

rate_scope: ACCOUNT

retry_after_seconds: 30

xsi_type: ns2:RateExceededError

We have moved from making ten of thousands of requests per day to several hundreds. We keep getting this message despite waiting much longer than 30 seconds.

Can you please help us understand why?

Thanks
