There's no way to include a direct Online Payment link like you can with invoice emails. ## Solution Unlike invoice emails, Online Payment tokens cannot be added to Marketing Pro campaigns. However, if your company uses Online Payments and the ServiceTitan Customer Portal, you can add a link to your Customer Portal to your marketing campaigns. The Customer Portal is a web portal where your customers can view their invoices, service history, and membership information with your company. They can also pay their outstanding balances and request appointments. > [!NOTE] > **Note:** Customers must create an account to the portal before they can log in and access their account. For more, see [Account creation](/v1/docs/customer-portal-overview#account-creation). --- ### #### Feature configuration - Account configuration is required to use the Customer Portal. Please contact [Technical Support](/v1/docs/contact-servicetitan-technical-support)for details. - [Online Payments](/v1/docs/guide-to-online-payments) is required to use the Customer Portal. ### Set up the Customer Portal First, set up the Company Portal for your company in **Settings**![A simple icon representing a settings gear. ](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/icon-gnav-settings-inactive.png)****.

While you can't turn off the automatic link shortening, you can edit the subdomain in the shortened URL in **Settings > Marketing Pro > Marketing > Subdomain Management**. 4. If your SMS campaign text message doesn't exceed the character limit, we recommend adding a note to the text message advising customers to click *Request an invitation* on the Customer Portal screen to create their account. ![Finish building your SMS campaign](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/how-do-i-send-automated-reminders-for-customers-to-pay-their-invoices-through-campaigns-image-ti283nfc.png) 5.
