To prevent run-off calls, which are billable, Youverify applies a rate limit to repeated identical requests on Enterprise accounts.

​
The rule

If the same call is made more than 3 times within 1 minute, further attempts are blocked and you cannot make that call for 10 minutes.

​
What counts as the same call

Two calls are the same when they carry the same payload, which in practice means they are made with the same ID. Calls with a different ID or payload are counted separately.

​
Why this exists

Repeated identical calls usually come from retry loops, duplicated jobs or integration bugs. Each call is billable, so the limit stops these run-off calls from accumulating charges.

​
What happens when you are blocked

A blocked call returns 429 Too Many Requests. The 10-minute block starts when the limit is hit. The timer does not restart if you keep calling during the block, so the block ends 10 minutes after it began.
Retrying a blocked call immediately does not shorten the block and is not needed. Wait for the block to end, then retry once.
  • Store the result of a verification and reuse it instead of calling again with the same ID.
  • Do not retry in a tight loop. When you receive a 429, stop and wait.
  • Use Test Data in the sandbox so that testing does not trigger the limit.
  • See Errors for how to handle other error responses.
