Each SmartSuite plan includes a monthly number of API requests: 25,000 on Team, 100,000 on Professional and 500,000 on Enterprise. Above that, requests slow down, and past 125 percent of the allowance the API is blocked until the next cycle or an add-on purchase.
There is also a per-second rate for each member. Going over it returns a 429 error.
Example: a compliance team syncs vendor records from its procurement system through the API every night. When a full resync pushes the month past its allowance, the Administrator turns on auto-billing so the sync keeps full speed.

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.
A 429 Too Many Requests error. The per-member rate was exceeded. Retry after the 30-second delay. See Check and reduce API usage.
Requests slowed to 2 per second. The workspace passed 100 percent of its monthly requests without auto-billing. See SmartSuite Limits.
API access blocked. Usage reached 125 percent of the monthly allowance. Access returns at the next billing cycle or when more calls are bought. See SmartSuite Limits.
More calls. With auto-billing on, SmartSuite adds 1,000 calls at 100 percent and restores full speed. See SmartSuite Limits.
Integration tools. Calls from Zapier, Make, Ply, Softr and similar tools count against the workspace total. See Check and reduce API usage.

Monthly request limits
API requests count per workspace and reset every month. Usage can reach 125 percent of the allowance at a slower rate before the API is blocked.
Team: 25,000 included, up to 31,250 with throttling.
Professional: 100,000 included, up to 125,000 with throttling.
Enterprise: 500,000 included, up to 625,000 with throttling.
Signature: custom.
Request rate limits
Usage. | Rate per member. |
Under the plan allowance. | 5 requests per second. |
Over the allowance, up to 125 percent. | 2 requests per second. |
Beyond 125 percent. | API access blocked. |
Rates apply per member, but every request counts against the workspace total. Going over the per-second rate returns a 429 Too Many Requests error with a 30-second retry delay.
The API calls add-on
Cost: $15 for each extra 1,000 API calls.
Where: Workspace Administration > Usage.
What counts: calls from integration tools such as Zapier, Make, Ply and Softr.
Auto-billing and manual purchases
Auto-billing on: at 100 percent, SmartSuite adds 1,000 calls and restores full speed. Each new block is added the moment the limit is hit.
Turned on after 100 percent: a 1,000-call block is added to your total, and full speed returns.
Auto-billing off: requests continue at 2 per second until 125 percent, then the API is disabled.
Manual purchase: a block bought by hand restores full speed. If usage reaches 125 percent of the new total, access pauses until the next cycle or another purchase.
Note: Administrators see usage warnings in Workspace Administration. Watch them before a large import or resync.
Why API limits exist
They keep SmartSuite fast for every customer.
They prevent abuse and keep use fair.
They protect against denial-of-service attacks.
They let you pay for extra use in small blocks.
Tip: Batch your writes. The bulk record endpoints change many records in one request. See Bulk Record Actions in the REST API.
