Is the API Gateway integration with S3 allow uploading larger files than 10MB?

Hi,

You are correct. That integration will not make the 10mb limit go away. That article only mentions an API GW ->S3 Integration type via AWS Service, instead of using a container/serverless in the middle.

Instead, to upload larger files via an API gateway, you would:

• Create an api gateway with a lambda proxy integration
• The function generates a signed URL granting upload access to S3 bucket and gives back the url to the user, as api response.
• The user can now upload larger files using a combination of S3 presigned urls and multipart upload.
