On your ServiceNow instance, navigate to **All** > **Advanced Work Assignment** > **Queues** and select your Queue. 2. On your Queue form, check the **External** field checkbox. 3. In the External third-party provider section, select the provider you chose while creating the payload. For more information, see [Create a payload for external third-party providers](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/conversational-interfaces/advanced-work-assignment/create-payload-extrnl-provider.md) If you need any additional information, add it in the `additionalParams` of the payload script, and select the added params from the **Document Fields to include** slush bucket. 4. From the FDIH Dashboard, select **Test**. While you want to test your flow action, ensure that you select the HTTP\(s\) Connection you configured previously, the Resource Path URL for the third-party external provider, and provide the sample payload. 5. In the script to run the FD, provide the necessary Work Item ID and the interaction sys\_id. 6. Verify that you have the third-party external provider URL in the outbound HTTP logs after testing. Open the third-party external CCaaS provider and verify the transaction logs for the endpoint. ## What to do next You can perform a quick setup test using the demo data by connecting to your external provider.
