# Creating an ID mapping workflow (provider services)
<a name="create-id-mapping-workflow-provider-services"></a>

After completing the [prerequisites](create-idmw-two-accounts-prerequisite.md), you can create one or more ID mapping workflows using the LiveRamp provider service. LiveRamp translates a set of source RampIDs to another set using either maintained or derived RampIDs.

**To create an ID mapping workflow using the provider service**

1. Sign in to the AWS Management Console and open the AWS Entity Resolution console at [https://console.aws.amazon.com/entityresolution/](https://console.aws.amazon.com/entityresolution/).

1. In the left navigation pane, under **Workflows**, choose **ID mapping**.

1. On the **ID mapping workflows** page, in the upper right corner, choose **Create ID mapping workflow**.

1. For **Step 1: Specify ID mapping workflow details**, do the following.

   1. Enter an **ID mapping workflow name** and an optional **Description**.

   1. For the **ID mapping method**, choose **Provider services**.

      AWS Entity Resolution currently offers the LiveRamp provider service as an ID mapping method. If you have a subscription to LiveRamp, then the status appears as **Subscribed**. For more information about how to subscribe to LiveRamp, see [Step 1: Subscribe to a provider service on AWS Data Exchange](prepare-third-party-input-data.md#subscribe-provider-service).

**Note**  
Ensure that your data input file format aligns with the provider service's guidelines. For more information about LiveRamp's input file formatting guidelines, see [Perform Translation Through ADX](https://docs.liveramp.com/identity/en/perform-transcoding-through-adx.html) on the LiveRamp documentation website.
