API Gateway

Limits

  • 29 seconds timeout
  • 10MB max payload size

Integrations

  • HTTP
  • Lambda 
  • AWS Service
    • For example, start an AWS Step Function workflow post a message to SQS
    • You can control the Authentication, deploy publicly, rate control

  • API Gateway has limit about 10 MB max payload size, so it won't be a good solution to upload a object to S3 if size is bigger than the limit.
  • Better to use Pre-Signed URL + Lambda to upload a file

  • Lambda has 15 mins timeout
  • API Gateway has 29 seconds timeout
