App hosted on Amplify getting HTTP 429 "Too many Requests" error

Hi,

AWS Amplify uses AWS API Gateway: https://medium.com/rahasak/build-serverless-application-with-aws-amplify-aws-api-gateway-aws-lambda-and-cognito-auth-a8606b9cb025

http 429 is a standard http error meaning too many requests: https://kinsta.com/knowledgebase/429-too-many-requests/ (it provides also details on why Wordpress may return 429

So, I would try to check for the problem in the API gtateway, which is part of your Amplify implementation, by following: https://repost.aws/knowledge-center/api-gateway-429-limit

All in all, you may have to resolve by extendiing your API Gateway quota, as describe in KC article.

Best,

Didier
