Spryng SMS API
What Spryng SMS API is
Spryng SMS API is a web-based service for adding programmable text messaging to online products and workflows. Founded in 2006 and headquartered in Amsterdam, Netherlands, it provides an SMS API for sending messages from applications. Two-way messaging lets systems send and receive texts, while delivery-status information shows message progress. Spryng uses pay-as-you-go billing and does not offer a free plan. Because the product is delivered through the web, its listed platform is web rather than a stated desktop or mobile application. The API model is suited to websites, software products, and other services that need application-controlled SMS communication. Teams can use the same integration for outbound messages, inbound replies, and delivery visibility. Spryng is therefore focused on connecting software workflows with text messaging rather than serving as a standalone messaging client.
