Automatic Data Processing ( ADP )
Automatic Data Processing

ADPis a global technology company that provides cloud-based human capital management (HCM) solutions and business process outsourcing services.
To connect Relyance AI with ADP, you will need a Client Secret, a Client ID and a Certificate Signing Request (CSR).
In ADP:
- Please note: if you can't find this information, please contact your Client Representative.
- Log in and navigate to the section for "Apps" or "My Apps."
- Click on "Register App" or a similar button to create a new application.
- You will need to provide details about your application, such as name, description, and potentially a callback URL
- Submit the application.
- After your application is registered, go to the "Apps" section and select the application you just registered.
- Look for a "Credentials" tab or a section that provides API keys or credentials.
- There, you should find your Client ID and Client Secret. These are unique identifiers for your application that you will use to authenticate with the ADP API.
- To get the Certificate Signing Request, please refer to this article: Generating a Certificate Signing Request
In the Relyance AI application:
- Login to your Relyance account.
- Navigate to the Settings Menu in the bottom left-hand side.
- Select Integrations.
- Search and locate the ADP integration card and click on it.
- Click on the Add Connection button on the top right.
- Provide a meaningful name for the integration and click on the Add button.
- In the Overview section, review the Scope and Permission, and Endpoint details and click on Continue. For more details, see Integration Features.
- In the Connection section, provide the appropriate values and click on Continue.
- In the Authentication section, provide the requested fields: Role Code, Base URL, Certificate (please refer to the tooltips), and the Client Secret and Client ID.
- Review the configuration summary from the Completion section and click on Finish.
- Confirm the integration Status reflects Connected.



If the connection reports Connected but returns nothing
These are the ways this integration comes back empty without reporting an error. Generated from the integration catalog, so it tracks what the connection actually asks for.
- Authorised, then empty. The connection carries an authorisation, not a password: it stops returning data if the account that granted it loses access, its own permissions narrow, or the grant is revoked at the vendor. None of that reports an error here -- the connection keeps its last status until the next scan.
- A credential rotated at the vendor is not picked up here. Client Secret is stored when you save the connection, so regenerating the value at the vendor breaks the next scan until it is re-pasted here. Recording the expiry on the connection means Relyance warns you before it lapses.
- Check the address fields before suspecting the credentials. Base URL identifies which tenant, region or host to talk to. A wrong value there fails authentication and looks exactly like a bad secret.
Authentication methods and fields
Pick one of these under Authentication Method on the connection wizard's Authentication step. This table is generated from the integration catalog, so it always matches what the form actually asks for.
| Method | Required | Optional |
|---|---|---|
| Two Legged Oauth2 | Role Code, Base URL, Client ID, Client Secret (secret), Certificate |

Manage this integration with Terraform
Connections for this integration can be managed as code with the Relyance Terraform provider. Non-secret fields go in auth.params; secret fields go in auth.secrets_wo, which is write-only — never stored in Terraform state. Rotate secrets by bumping auth.secrets_wo_version.
