Redefining integration: How Clock's full API empowers hotel technology customisation

Share this post

For us, the presence of an API is a fundamental aspect of system design, akin to essential components in a car. Since the inception of our cloud-native project in 2013, our API has facilitated data exchange and custom workflow creation for hundreds of applications, ranging from industry-standard hotel technology apps to bespoke solutions developed by our hotel partners.

Unlike previous generations of hotel technology, where connectivity was often a complex and costly nightmare, our API has always been publicly available, enhancing accessibility and integration ease. Full documentation and support are readily accessible on our developer's pages.

The hotel tech API evolution

Before the era of OpenAPI, connecting with the main PMS systems, especially those from the most renowned branches of the previous generation, was frequently a technological challenge, often impossible or subject to exorbitant fees.

The landscape has significantly changed as we approach the third decade of the 21st century, and now, most hotel tech vendors offer such APIs.

Let's explore what sets Clock's API apart from others in the market.

1. Full API philosophy

Many tech providers offer specialised endpoints for specific tasks, but at Clock, this approach might limit our partners' potential. Instead, we adopted a 'full API' strategy, granting unrestricted access to our service's functionalities, thus enabling limitless customisation and integration possibilities.

By not confining our partners to predefined endpoints, we allow for the creation of customised solutions that are not only tailored to specific operational needs but also to unique guest service standards and market demands.

2. Full API strategy

Our vision was to create an API that could support the exchange of basic data and automation of standard processes and be robust enough to accommodate any conceivable operational need.

This approach allows partners to develop bespoke applications, like custom Property Management Systems (PMS) overlays, including tailored booking workflows, script management, or invoicing screens.

Such capabilities are essential for partners in niche markets where standard workflows do not meet their needs.

3. Scalability and reliability

The scalable architecture hosted on Amazon Web Services (AWS) supports the scalability and reliability of Clock's API. This foundation ensures the highest service uptime and minimal response times, making it suitable for business-critical applications requiring high availability and performance.

Top integration support

At Clock, we recognise that seamless integration and robust support are crucial for our partners' success. As part of our commitment to providing top-tier integration support, we offer a comprehensive suite of resources and assistance to ensure your smooth and efficient integration journey.

1. Extensive documentation and guides

Our developer portal offers detailed API documentation and best practices guides. These resources cover many integration scenarios, including popular hotel tech applications like POS systems, channel managers, payment providers, fiscalisation services, and door lock systems, ensuring you have the information you need to build effective integrations.

2. Free sandbox accounts

We provide free sandbox accounts to facilitate the development and testing of integrations. These accounts allow you to experiment with the API in a risk-free environment, ensuring your integration works perfectly before going live.

3. Personalised support and consultation

We understand that sometimes you need personalised help. Our team is available to answer specific questions and provide guidance on data modelling or workflow planning. We offer in-depth consultation services for complex issues at a reasonable rate, including examining and fixing error notifications, which ensures quick resolution of any issues.

4. Validation and certification

We offer validation and certification services to ensure your integration meets our standards and operates smoothly within the Clock ecosystem. This process includes up to three sessions of free validation, after which you can request additional sessions if necessary.

5. Pilot customer requirement

We recommend identifying a pilot customer before starting the integration process for custom project integrations to ensure that the integration meets real-world needs and avoids the risk of obsolescence from system updates.

6. API fair use policy

Our API infrastructure, hosted on Amazon Web Services, is designed to handle high loads with minimal response times and is suitable for business-critical applications. We provide a generous allocation of complimentary CPU usage each month to maintain this. A minor fee is applied to ensure sustainability for usage that exceeds this allocation. This policy encourages efficient API use, benefiting all parties involved.

With these support measures in place, our goal is to help you create powerful, reliable integrations that enhance the functionality and efficiency of hotel operations, benefiting both our partners and mutual customers.
