    "We can now offer more available customer service"

    By integrating GatewayAPI into our own CRM system, we can offer a much better available customer service. Our internal processes are also more effective. We're now sending fewer messages per customer without changing the amount of information we share. We just send fewer reminders as customers read the text messages and act on them immediately.

    "The encrypted flows in Premium have met our requirements perfectly"

    It was important to us that the system we chose was secure as our messages contain confidential information. The encrypted flows in GatewayAPI Premium met our requirements perfectly. There is something very powerful about text messages. Most people read text messages instantly and are more likely to respond to a text message than to an email.

    "Everything is simply in its place"

    I've rarely been part of a project with so many organizations and such a short deadline, where everything just came together. Kudos to the team behind GatewayAPI, which solved the tasks so professionally.

    Steen Bechmann Henningsen, IT manager at the Roskilde Festival

    "United in our focus on reliability and availability of support"

    It was clear that GatewayAPI and I agreed on our focus on stability, reliability and availability of support. We had a very open and informal dialogue and there was always enough time to discuss details or ask for special requests. As a result, the entire implementation went very smoothly. The good cooperation continued after the first implementation.

    "Proactive and extremely competitive prices"

    We decided to work with GatewayAPI for several reasons. First, their interfaces are user-friendly, their documentation and approach to the SMS API seem logical and easy to implement. In addition, they have been proactive about new solutions and, last but not least, their prices are extremely competitive.

    "API is well described and easy to integrate"

    We chose GatewayAPI and not competing solutions because the API is well documented and therefore easy to integrate. In addition, GatewayAPI was able to provide an SMS solution covering all required countries. When Minuba first contacted GatewayAPI, we experienced personal service with positive help that made our choice easy.
