Exposed WebAPI GET request size limit?

Question

I have found information regarding a 5MB limit when my Appian application uses an Integration Object to call another API hosted on an external system. 
 However, if my Appian application is exposing a WebAPI, so that an external system can make a GET request to my Appian application, is there a size limit on the JSON payload that my Appian WebAPI can return to that external system?

No official size limit on Web API GET JSON responses, but use pagination to stay under practical memory/timeout constraints (~10MB recommended). URL length limits GET params (~8K chars); switch to POST for larger payloads.

With data volumes growing every day, you will have to implement paging and a page size limits anyways.
