+## Create a new endpoint for a client

+### Create basic infrastructure
+Within the [Cloud Platform Environments GitHub repository](https://github.com/ministryofjustice/cloud-platform-environments/tree/main) and the namespace of the environment:
+
+1. Create a branch.
+2. Add a new API Gateway resource, a SQS method, a SQS method response, and an integration. Example: [api_gateway.tf](https://github.com/ministryofjustice/cloud-platform-environments/pull/22695/files)
+3. Ensure that all the permissions are up-to-date and add a new role and policy for your new resource. Example: [iam.tf](https://github.com/ministryofjustice/cloud-platform-environments/pull/22787/files#diff-a376622fa4a4c2fd9404d5ee4221487259264608a0cbe36b99c150c472558f29)
+4. Check that the integration is pointing to the right queue. Example: [api_gateway.tf](https://github.com/ministryofjustice/cloud-platform-environments/pull/22795/files)
+5. Deploy and test (do not use Postman, rather use a GET cURL command with "x-api-key" as your header.)
