Front's API rate limit

To improve performance and prevent abuse of our API, Front has two rate limits. By default, Front's API rate limits start at 100 requests per 60 seconds and can be increased depending on your plan. For example, customers with the Prime plan (and above) have a default rate limit of 200 requests per 60 seconds.

Some resource-intensive endpoints are also subject to additional "burst" rate-limiting to prevent strain on Front's infrastructure. Generally, there is a limit of 3 calls per second, per resource type (except for exports, which is 1 per second). A resource is an API endpoint that has an ID like:

POST https://api2.frontapp.com/channels/{channel_id}/incoming_messages

In the example above, there is a limit of 3 requests per second enforced at the channel level. You will receive X-RateLimit headers in the responses of your API calls letting you know how close you are to exceeding your rate limit.

If you need to increase your API rate limit, please consider purchasing the Increase API Rate Limit add-on to double your current API rate limit, or contact api@frontapp.com to discuss strategies for optimizing your API usage.
