Request Limits

To ensure service health and stability, Qualtrics enforces a limit on how rapidly APIs can be called.

Qualtrics enforces two rate-limits: 1) Total number of calls per brand, 2) Total number of calls to an endpoint per brand.

Total number of calls per brand

Brands may make up to 3000 API requests per minute across all of its API calls. This request limit is enforced at the brand level.

Total number of calls to an endpoint per brand

In addition to the Per Brand Limit, certain endpoints have a lower per brand limit to the number of calls that they will support per minute. What this means is that while a brand may make 3000 requests per minute, some endpoints will engage rate-limiting at a lower number of calls per minute. If an endpoint has a rate limit below 'Total number of calls per brand' (3000 requests per minute), a brand may encounter the endpoint rate limit, but still be able to make successful calls against a different endpoint until it hits the 'Total number of calls per brand' limit

APIs with Lower Request Limits

Some APIs have lower request limits per minute. The limit for each endpoint is listed in the following table.

API Call Duration

To ensure responsive APIs, Qualtrics APIs have a 5 second call timeout. In very rare cases an API may have a longer timeout, this will be noted on API reference page.

Survey Response Limits

The maximum number of records per survey response data file is 1M. If the maximum number of rows of data is reached, additional data files will be included in the .zip file in the format: {surveyname}_{filenum}.{fileExtension}

Mailing List Limits

Mailing list names are limited to 100 characters.

File Size Limits

Maximum file upload size is 5 MBs unless specified otherwise by the endpoint documentation.
