 For convenience, support for common APIs is already built into this adapter and available via the `ApiPayloadConverter`. The following is a list of currently supported API providers:

+- [AWS Simple Email Service (AWS JavaScript SDK v3)](https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/clients/client-ses/index.html)

+This is an example for the AWS Simple Email Service client using the AWS JavaScript SDK v3:
+
+```js
+// Configure mail client
+const { SES, SendEmailCommand } = require('@aws-sdk/client-ses');
+
+const {
+  fromInstanceMetadata, // Get credentials via IMDS from the AWS instance (when deployed on AWS instance)
+  fromEnv, // Get AWS credentials from environment variables (when testing locally)
+} = require('@aws-sdk/credential-providers');
+
+// Get AWS credentials depending on environment
+const credentialProvider= process.env.NODE_ENV == 'production' ? fromInstanceMetadata() : fromEnv();
+const credentials = await credentialProvider();
+
+const sesClient = new SES({
+    credentials,
+    region: 'eu-west-1',
+    apiVersion: '2010-12-01'
+});
+
+// Configure Parse Server
+const server = new ParseServer({
+    ...otherServerOptions,
+
+    emailAdapter: {
+        module: 'parse-server-api-mail-adapter',

 ## Custom API
 
 This is an example of how the API payload can be adapted in the adapter configuration `apiCallback` according to a custom email provider's API specification.
