In order to maintain an efficient, secure, and high-performing API, Bitly places limits on the amount of data that can be consumed in any given period. There are two types of rate limits that will affect your usage: plan limits and platform limits.
Retrieve your current limits and usage via the API.
Platform limits apply to all accounts, regardless of subscription plan. Bitly enforces per-hour, per-minute, and per-IP rate limits for each API endpoint.
IP address limit: API users are limited to a maximum of five concurrent connections from a single IP address.
Hourly limits: The rate limits reset once each hour and once each minute. The per-minute limit is one-tenth of the hourly limit. So if your limit for the /v4/shorten endpoint is 1,000 calls per hour, it will also be limited to 100 calls per minute.
Requesting higher hourly limits: Increasing platform limits requires a subscription to a custom enterprise-level account. To discuss an increase to your hourly limits, please contact your account manager for assistance.
From our free plan to our customized enterprise-level plans, every Bitly account has a monthly limit on the number of transactions its users can take. As you move up our subscription plan tiers, you can shorten more links, customize more links, access more click data history, and access more features, such as Campaigns. Each of those limits corresponds to an API endpoint and applies across all transactions in the API and the Bitly apps.
For customers who upgraded through our website, you can find your limits and features on our pricing page. If you have an Enterprise or customized account, please consult your contract or contact your account manager for your plan's details.
You can also find your monthly link limits by logging into Bitly, clicking the profile menu, selecting Change Group, and then clicking Manage next to the appropriate account name. This will take you to the Account Settings page.
Requesting higher monthly limits To increase your plan limits or access unavailable features, you will need to subscribe to a higher plan or contact your account manager for assistance.
Reaching a limit: The 429 error
If you exceed your per-hour or per-minute call limit, you will receive a 'RATE_LIMIT_EXCEEDED' 429 error message. You'll then need to wait for one hour or one minute (depending on which rate limit you've hit) to resume making API calls to that endpoint.
If you contact Bitly Support to help you with troubleshooting an API limit issue, please include:
- A description of how you are using the Bitly API.
