Rate Limiting

Fivetran limits the following actions at the account level for a rolling time period:

Limit	Trial Accounts	Free / Standard / Enterprise / Business Critical Accounts
Setup test requests per minute	-	250 max per minute
Setup test requests per hour	50 max per hour	2,500 max per hour
Source interaction requests per minute	25 max per minute	500 max per minute
Source interaction requests per hour	250 max per hour	5,000 max per hour
User creation	10 max per hour	500 max per hour
All requests	500 per hour	20,000 per hour

Note: The endpoints, which run setup tests directly or indirectly, are:

Create a connector with run_setup_tests: true
Modify a connector with run_setup_tests: true
Run connector setup tests
Create a destination with run_setup_tests: true
Modify a destination with run_setup_tests: true
Run destination setup tests

Note: The endpoints, which require interaction with a source, are:

All endpoints, which run setup tests directly or indirectly.
Reload a connector schema config
Retrieve source table columns config

Note: Source interaction requests limit includes all requests which require to run setup tests. This means that if you have executed 100 requests requiring setup tests in a minute, you're able to make no more than 400 other requests requiring source interaction (e.g. Reload a connector schema config or Retrieve source table columns config).

For the overall HTTP requests quota we provide HTTP headers in the response:

X-Rate-Limit specifies the overall HTTP requests limit.
X-Rate-Limit-Remaining specifies the number of remaining requests for the current one-hour rolling time period.

If an API limit has been exceeded, it might respond with an HTTP 429 error. The response is going to contain Retry-After HTTP header specifying the number of seconds to wait before the request can be sent again.

HTTP 429 Too Many Requests

Retry-After=3600
