Limits

To assure good performance for every project using commercetools Composable Commerce, the API imposes limits on certain parameters and objects.

Some limits can be increased per project on customer request. Most limits only apply to projects created after the introduction of the respective limit.

The current value of a project's limits can be accessed via the limits field on the GraphQL API. If the limit applies to the total amount of a resource type, the current usage can be accessed as well.

General

JSON document size

JSON documents persisted through any API endpoint must not be larger than 16 megabytes. If an update action causes an existing resource to exceed this size limit, the request will fail with a ResourceSizeLimitExceeded error. This limit isn't related to the general request size. Even if a request is smaller than 16 megabytes, if it causes the resulting document to go over this limit, the request will fail.

For best performance, we recommend limiting your average documents to no more than 100 KB, and large documents (for example, a Product with many Product Variants, or an Order with many Line Items) to 2 MB.

Field content size

For performance reasons, the maximum size of a searchable field within an AttributeDefinition can not exceed 10 922 characters.

Non searchable fields are only limited by the overall JSON document size.

String content limits

Any limitations in length and content of string fields are documented in the API reference of each resource with MinLength, MaxLength, and Pattern. If a Pattern is not specified, any UTF-8 encoded Unicode characters are accepted. Additionally, the length of string fields is limited by the overall JSON document size.

Slugs

A Slug must match the pattern [a-zA-Z0-9_\-]{2,256}, hence they are limited to 256 characters.

Queries

Within a query, up to 500 elements can be fetched.

When using pagination, the maximum offset is 10 000. The total field of PagedQueryResult is limited to the maximum offset when the results are filtered with a Query Predicate.

See our performance tips for best practices in optimizing queries.

Update actions per request

For performance reasons, the maximum number of update actions within a single request is limited to 500.

GraphQL

Queries with a complexity score greater than or equal to 20 000 are not executed, and a QueryComplexityLimitExceeded error is returned.

Load testing

Visit Load testing to learn about the limits and exclusion periods that apply.

Authorization

External OAuth 2.0 endpoint timeouts

If a project is using OAuth 2.0 access tokens issued by an external OAuth 2.0 introspection endpoint, the OAuth 2.0 service must respond in 500 ms, including network latency.

If the introspection endpoint does not respond within the time limit, or no connection could be established, the overall request will fail with a 504 Gateway Timeout or 502 Bad Gateway HTTP status code and an ExternalOAuthFailed error code.

Refresh tokens

The number of refresh tokens is limited to 10 million. If the limit is exceeded, the least recently used refresh tokens are deleted. Creating new refresh tokens continues to work.
