Rate limit
A rate limit policy covers all the endpoints of the API.
The sandbox and production environments have different rate limit.
| Environment | Requests/min | Requests/hour |
|---|---|---|
| Sandbox | 30 requests/min | 200 requests/hour |
| Production | 60 requests/min | 1200 requests/hour |
An additional daily limit of 100 Signature Requests applies in the Sandbox environment during the API trial period.
Your remaining calls quotas are sent in all the API responses through X-Ratelimit-Limit-Remaining-Minute and X-Ratelimit-Limit-Remaining-Hour HTTP headers :
HTTP/2 429
< x-ratelimit-limit-hour: 1200
< x-ratelimit-limit-minute: 60
< x-ratelimit-remaining-hour: 1197
< x-ratelimit-remaining-minute: 59
If one of your calls is rejected because a rate limit threshold is hit, you will receive the status code 429 and "too many requests" as explanation.
The rate limit policy can be customised to fit your needs
If your implementation respects our standards (mainly use Webhooks instead of regular polling), you can request a change in your Rate-limit.
Please fill out this form.
Our support team will review your request and work with you to find the best solution.
Please keep in mind that:
- It may take few days to treat your request
- It is required to have an existing API Key in the targeted environment (sandbox or production)
