Configuring WebService {#adobe-commerce-m-conf-webserv}
=======================================================

The WebService configuration includes the default `Adobe Commerce` merchant ID (applies to all the payment methods), the REST shared key, and the SOAP key detail. Follow these steps to complete the configuration:

1. Click WebService Configuration to expand the section.

2. In the Merchant ID field, enter your `Cybersource` merchant ID.

3. From the Test Mode drop-down list, choose:

4. * Yes to use the `Business Center` testing environment.
   * No to use the production `Business Center`. Optionally, in the Developer ID field, you can enter the developer ID. The ID cannot exceed eight characters. You can also request that `Cybersource` assign you a developer ID.

5. In the Simple Order P12 Key File section, upload the SOAP p12 certificate and then enter the Key Password. If you did not generate a key, see [Creating a SOAP p12 Certificate](https://developer.cybersource.com/docs/cybs/en-us/so-p12/migration/all/so/so-p12/so-p12-create-p12.md "") for instructions.

6. In the REST API Key Detail field, enter the REST key you generated from the `Business Center`. If you do not have a REST Shared Secret Key Pair, see [Creating a Shared Secret Key Pair](https://developer.cybersource.com/docs/cybs/en-us/security-keys/user/all/ada/security-keys/keys-manage/keys-rest-shared-intro/restgs-security-key-pair-task.md "") for instructions.

   #### ADDITIONAL INFORMATION

   Proper configuration of the SOAP WebService is required for the functioning of other services including Tax Calculation, Secure Acceptance, PayPal, Account Takeover Protection, and Apple Pay. If you experience issues with these modules, verify that the SOAP WebService options are configured correctly. The SOAP p12 Certificate must have the correct password and the Test Mode option must match the correct environment for the `Cybersource` `Business Center` (test).

7. In the REST API Shared Secret Key field, enter the Shared Secret key you generated from the `Business Center`. If you do not have a REST Shared Secret Key Pair, see [Creating a Shared Secret Key Pair](https://developer.cybersource.com/docs/cybs/en-us/security-keys/user/all/ada/security-keys/keys-manage/keys-rest-shared-intro/restgs-security-key-pair-task.md "") for instructions.

   #### ADDITIONAL INFORMATION
