# AddEndpoints
<a name="API_AddEndpoints"></a>

Add endpoints to an endpoint group. The `AddEndpoints` API operation is the recommended option for adding endpoints. The alternative options are to add endpoints when you create an endpoint group (with the [CreateEndpointGroup](https://docs.aws.amazon.com/global-accelerator/latest/api/API_CreateEndpointGroup.html) API) or when you update an endpoint group (with the [UpdateEndpointGroup](https://docs.aws.amazon.com/global-accelerator/latest/api/API_UpdateEndpointGroup.html) API). 

There are two advantages to using `AddEndpoints` to add endpoints in Global Accelerator:
+ It's faster, because Global Accelerator only has to resolve the new endpoints that you're adding, rather than resolving new and existing endpoints.
+ It's more convenient, because you don't need to specify the current endpoints that are already in the endpoint group, in addition to the new endpoints that you want to add.

For information about endpoint types and requirements for endpoints that you can add to Global Accelerator, see [ Endpoints for standard accelerators](https://docs.aws.amazon.com/global-accelerator/latest/dg/about-endpoints.html) in the * AWS Global Accelerator Developer Guide*.
