Additionally, a REST API allows for single and batch message dispatches, checks on delivery statuses, and the retrieval of incoming messages. The platform also provides seamless connections to tools like Shopify, WooCommerce, and Google Sheets, enhancing workflow management for online stores and spreadsheets. A complimentary plan is offered, while premium subscriptions enhance features such as message volume, device connectivity, API functionalities, automation capabilities, and additional integrations.
