Client Options
Each client accepts an optional set of options when constructed. The following example sets static credentials for an SQS client:
var Options := TSQSOptions.Create as ISQSOptions;
Options.AccessKeyId := '...';
Options.SecretAccessKey := '...';
SQS := TSQSClient.Create(Options);
Options can configure credentials, retry behaviour, endpoints, and more. See AWS Options for full details including how to compose service-scoped options.
