Customers’ updates can be completed from the dedicated list view and applied to several at once. [Filter them](/en-us/upflow-configuration/organization-configuration/filters) per your interest criteria (including your custom fields), and save the view if you are likely to access the same list again. | Click the Actions button, select the operation you want to perform, and let the app guide you through: * [Assign a workflow or one/several users](/en-us/core-entities/customers/assign-users-or-workflows-to-your-customers) * [Assign a payment method](/en-us/payments/accept-online-payments/managing-online-payment-methods) * [Modify custom field values](/en-us/core-entities/others/import-and-create-custom-fields-into-upflow) * [Enable/Disable Autopay](/en-us/payments/collect-online-payments/collecting-automatically-with-autopay) * [Enable/Disable surcharges](/en-us/payments/collect-online-payments/passing-card-surcharges-on-to-customers) * [Create Action campaigns](/en-us/collection-and-collaboration/run-your-collection/action-campaigns) 💡 Manage this list like the others: hide/display and rearrange columns, save your preferred views to access them in a click, search/filter... ## From another source system You can alternatively opt for updates from different source systems * [Connect Salesforce](/en-us/integrations/salesforce/connect) to your organization and automatically assign your Account owners as Upflow Assigned users. * Update your customers’ workflow, assigned user(s), custom fields, and payment method(s) via API. * Pull the information using our [Update Customer endpoint](https://upflow.docs.apiary.io/#reference/0/customers/update-customer) * Configure behaviors triggered by your source system’s events with automation tools such as Zapier (ex: assign a workflow based on a customer’s payment method with a PUT request) * Import a CSV file to mass-assign Workflows and Account managers ([learn more](/en-us/core-entities/customers/import-and-update-your-customers-via-csv)).
