To improve performance and prevent abuse of our API, Front has two rate limits, global and burst. 

The global rate limit is the combined limit of requests across all public API endpoints.  By default, Front's API rate limits start at 50 requests per 60 seconds and depends on the pricing plan your company is on. For example, customers with the Scale plan have a default rate limit of 200 requests per 60 seconds. Contact your account manager to discuss increasing your rate limit beyond the default amounts.

Note that API requests made by a partner integration on behalf of a company via OAuth have a separate rate limit of 120 rpm (enforced on a per-company basis). This means that API requests made by integrations you install will not count against your rate limit, unless you have manually provided one of your API tokens to the integration.

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 5 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 5 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.

For the complete list of endpoints subject to burst rate limits, see our developer documentation. 

Further technical details of Front's API rate limit can be found in our developer documentation.

If you need to increase your API rate limit, please consider purchasing an API rate limit add-on (see below), a higher plan tier, or contact api@front.com to discuss strategies for optimizing your API usage.  

If you’re on the Growth plan or above, you can purchase an API rate limit add-on to increase your company’s rate limit.

• Cost: $600 per month per add-on

• Rate limit: Access to an additional 300 calls per minute per add-on

• Maximum number: 2 add-ons per company

Step 1
