The GraphQL Leads API has limitations in place to protect against excessive or abusive calls to Swapcard servers.

The GraphQL Leads API limit has two types of rate limiting:

  • Call based limit
  • Cost based limit

The call based limit counts the number of requests issued at the API during a given time. The call based limit is set at 1000 points every minute. A request consumes 10 points. For regular users, it is equivalent to 100 queries per minute.

You can check your current usage by checking the following headers in an API response:

  • X-RateLimit-Limit: The maximum number of points that the consumer is permitted to make per minute.
  • X-RateLimit-Remaining: The number of points remaining in the current rate limit window.
  • X-RateLimit-Reset: The time at which the current rate limit window resets in UTC epoch seconds.
  • Retry-After: The number of seconds to wait before retrying the request.

The cost based limit is specific to GraphQL APIs. With GraphQL, one call can replace multiple REST calls. A single complex GraphQL call could be the equivalent of thousands of REST requests.

The GraphQL Leads API can limit your queries based the following criteria:

  • Cost: Maximum 20,000 points per query. An object is 2 points, a scalar is 1 point, depth factor applied is 1.5x
  • Depth: Maximum 20 levels.
  • Aliases: Maximum 50 aliases.
  • Tokens: Maximum 2,000 tokens.
  • Directives: Maximum 20 directives.

If your application requires different limits than specified above, please contact the support and include details on why it is necessary for your application to use different limits.

Heads up!

The minimum cost of a call to the GraphQL API is 1, representing a single request.

The size of the request body must not exceed 15 megabytes.
