Rate Limits

Know your limits

In the Visma eAccounting/Lön Smart API we have a limit on how many requests you can make during a given period. These are the rules:

  • 600 requests per minute
  • Limit is registered per client and endpoint/URL

If you hit the rate limit you will get a specific response back from us.

HTTP/1.1 429 Too Many Requests
Content-Type: application/json;charset=UTF-8

    "ErrorCode": 4010,
    "DeveloperErrorMessage": "API calls quota exceeded! maximum admitted 600 per Minute. Try again in 55 seconds.",
    "ErrorId": "3fa7da17-eeb2-48f6-997d-0be158f4cba4"

As soon as the number of requests is below the limit, the response will go back to normal again.
