API Transaction Limits

Understand SmartSuite subscription plan API transaction limits

Written by Peter Novosel

To ensure a fast, secure, and reliable experience for everyone, SmartSuite sets limits on API usage. These limits are based on how many API requests your workspace can make each month, and how quickly users can make them per second.

My API requests are throttled or blocked: check these five things, in order

Administrators monitor usage and manage the add-on in Workspace Administration > Usage. If you are not an Administrator, send this page and the error you received to one.

  1. A 429 Too Many Requests error. The per-user rate cap was exceeded; retry after the 30-second delay. Within the plan limit the rate is 5 requests per second per user. See Request Rate Limits.

  2. Requests slowed to 2 per second. The workspace passed 100 percent of its monthly requests without auto-billing. See For Paid Plans.

  3. API access blocked. Usage reached 125 percent of the monthly limit; access returns at the next billing cycle or when more calls are bought. See Monthly Request Limits.

  4. More calls. With auto-billing on, SmartSuite adds 1,000 calls at 100 percent and restores full speed; a manual purchase of a 1,000-call block does the same. See Auto-Billing Behavior.

  5. Integration tools. Calls made by Zapier, Make, Ply, Softr and similar tools count against the workspace quota. See Add-On Overview.

Still stuck: select the chat button in the lower-right corner of SmartSuite. The last block of the panel shows the service status, and Send a message in the same panel reaches support. Include the workspace name, the endpoint you called, the response code and the time of the request. The limits of every kind are in Limits in SmartSuite.


📊 API Usage Limits by Plan

SmartSuite plans come with monthly API request limits. If you exceed them, your access is throttled—and eventually paused—unless you add more capacity through the API Calls Add-On.

⚠️ SmartSuite allows API usage up to 125% of your plan’s monthly limit. Beyond that, API access is blocked until the next billing cycle begins.

Beyond 125% of plan limit

API access blocked

  • Limits are enforced per user, but all usage counts against the workspace-wide quota.

  • Exceeding the rate cap results in a 429 Too Many Requests error with a 30-second retry delay.


🆕 API Calls Add-On

SmartSuite offers flexible ways to extend API usage through the API Calls Add-On.


Add-On Overview

  • Cost: $15 per additional 1,000 API calls

  • Control & Monitoring: Workspace Administration → Usage tab

  • API Usage Tracking: Includes calls made by integration tools like Zapier, Make, Ply, Softr, and others


Auto-Billing Behavior

  • When ON:

    • Once you reach 100% of your API limit, SmartSuite automatically adds 1,000 more calls and restores full-speed access (5/sec per user).

    • Each new block is added immediately when the limit is hit.

  • If toggled ON after passing 100%:

    • A new 1,000-call block is added to your current total, returning your workspace to full-speed usage.

  • When OFF:

    • Usage continues at the 2/sec rate until 125% of the plan limit is reached.

    • After 125%, API access is disabled unless you manually purchase more calls.


Manual Purchase Behavior

  • You can manually purchase additional API calls in blocks of 1,000.

  • Doing so resets access to full speed just like automatic billing.

  • However, if your usage again reaches 125% of your updated total, API access will pause until:

    • The next billing cycle, or

    • You purchase more blocks.


⚠️ What Happens When You Hit Your Limit

If you hit your limit and do not have auto-billing for overages enabled, the system will take the following actions:

  • Rate-limited users will also receive a 429 error if they exceed the per-second cap.

🔄 Why API Limits Matter

These limits are in place to:

  • Maintain SmartSuite’s performance for all users

  • Prevent platform abuse and ensure fairness

  • Protect against security risks like denial-of-service (DoS) attacks

  • Provide affordable scaling options through metered add-ons
