HERE server environments

HERE provides a Production environment for handling your requests:

The Production environment is not designed to support sudden, unannounced high loads, including performance tests. If you need to do performance testing, contact HERE to discuss options.

Rate Limiting

The rate limits for Tour Planning API are two requests per second per realm (customer), which applies to both synchronous and asynchronous endpoints. For requests over that limit we return an error response with http response status code 429.

Best Practices

Here are some guidelines for rate limits:

• Keep track of your API activity and see how it measures against limits.
• The API returns an error response with http response status code 429 if the rate limit is exceeded. Consider handling rate limiting errors explicitly, for instance, with a delayed retry in your code.
• If you continue to receive the error, consider reducing the number of API requests or spacing them more regularly.
