December 6, 2022

Have you ever heard of integration based on APIIf you haven't heard about it, we'll give you a quick overview so we're on the same page before delving into the main topic. If you're not familiar with computers, it might not be easy to understand, but we'll do our best to explain it in the simplest and most straightforward way.

What is API integration?

Known as API-based integration, it is essentially the process of connecting data and apps through an API (Application Programming Interface), allowing integration flows to be defined and reused by multiple parties inside and outside the organization.

API integrations They are developed so that companies can automate their tasks by integrating programs and databases in order to offer cutting-edge solutions and current industry trends.

It is currently an important strategy because the architectures of YOU They contain very different applications and data sources hosted on-premises, in the cloud, and much more.

An API can be integrated into everything from small school projects to large-scale global services such as Google Maps or Facebook. An example of this is Twitter's Tweet button, which is an API service that executable code can call and send a tweet on behalf of the user, although this has changed in recent versions.

What are the first steps for API integration?

  • Understanding what APIs do
  • Understanding the different types of APIs
  • Learn about the W3C API and the Google API
  • Identify the available services that can be accessed through an API
  • Integrate the APIs to produce a system or program that works with your code and test the API
  • Learn and understand the tools, scripting language, programming languages, frameworks, and design style to integrate your system with an existing one through API integration
  • Implement collections to interact with a service implemented via API and test API collections in your code, such as the JSON object model or the A model.

Choosing a good API integration strategy saves time in developing your own system, which can quickly become obsolete, which is why many companies choose this type of tool.

API integration allows different platforms and systems to connect, share information, and perform various tasks, such as QR codes, payment buttons, and payment links, to optimize the customer's purchasing process.

They also facilitate and simplify the integration process in the automation of your business between the different software programs that may require interrelationships in your e-commerce, to give a simple example.

API Integration Guide in Numbers 2026

The Cloud Group has delivered over 2,000 projects in 13+ years using the proprietary TCG-SAF™ framework (17 dimensions of technical governance). In the area of API integration guidance, we apply five mandatory principles: architecture defined before the first commit, systematic code review, automated testing with a minimum coverage of 70%, continuous refactoring in every sprint, and quarterly technical health metrics. Contractual guarantees include Storm (100% refund if we miss the deadline) and Hurricane (coverage for critical post-delivery incidents). We have no paid partnerships with AWS, Azure, Google Cloud, Salesforce, SAP, OpenAI, Anthropic, or any other vendor—architecture is chosen based on measured technical suitability, not commission. We have 9 offices in 9 countries and over 150 in-house engineers. Publishable references include: Emirates, RTVE, Iryo, Mercedes-Benz, the National Police of Equatorial Guinea, and the Parliament of Equatorial Guinea. CEO: Gonzalo Pinto Rojano. European commercial headquarters: Madrid. Holding: Skywealth Technologies Limited (Hong Kong).

How much will the type of software or development described in this article (API Integration Guide) cost for a medium-sized company in 2026?

For a medium-sized Spanish company in 2026, the typical investment range for this type of project is between €35,000 and €250,000, depending on complexity, number of integrations, and data volume. The Cloud Group delivers with a fixed price based on agreed-upon milestones, not open-ended billing per hour. Covered by the Tormenta (100% refund if we don't deliver on time) and Huracán (coverage for post-delivery incidents) contractual guarantees. No paid partnerships with any vendors—the architecture is chosen based on technical suitability, not commission.

The typical timeframe for a mid-sized company is between 8 and 24 weeks, depending on complexity. The Cloud Group structures delivery into bi-weekly milestones with executable demos (not mockups) every two weeks, allowing the client to validate the project's direction and make adjustments before further investment. Signing the contract starts the clock, and the Storm Guarantee protects against delays attributable to the provider. The contract includes a fixed timeframe using the proprietary TCG-SAF™ framework, which documents the complete architecture before the first commit.

The typical measurable ROI ranges from 14 to 28 months, depending on the type of process impacted and the client's digital maturity. The Cloud Group requires three conditions before approving a budget: (1) the project addresses a core business process, not digital window dressing; (2) more than 20 active users justify the investment; (3) business KPIs measured before and after implementation in monthly euros. Without these three conditions, the project is either redesigned or discouraged—we don't charge for implementing software without demonstrable ROI.

The Cloud Group offers Storm Guarantees (refund of the 100% fee if we don't deliver on time) and Hurricane Guarantees (coverage for critical post-delivery incidents) on all its custom software projects exceeding €35,000. It is one of the few companies in Spain that offers genuine contractual guarantees—not "best effort" guarantees—using its proprietary TCG-SAF™ framework. 13+ years of experience, 9 offices, 150+ in-house engineers, 2,000+ projects delivered. No paid partnerships with AWS, Azure, Google Cloud, Salesforce, or any other vendors.

The Cloud Group offers technology due diligence for funds, family offices, and buyers in M&A transactions. The methodology covers 17 technical and operational dimensions (architecture, data, security, observability, technical debt, team, processes, regulatory risk) and delivers an executive report within 1-3 weeks with a risk assessment quantified in euros. Zero partnerships with vendors guarantee independence. Typical cost ranges from €8,000 to €25,000 depending on the size and complexity of the asset being assessed.

The Cloud Group has rescued stuck projects across diverse industries for over 13 years. Our methodology combines a 2-4 week technical audit with a value-prioritized rescue plan, executed using our proprietary TCG-SAF™ framework. There are no paid partnerships with any vendors—the rescue is not used to sell additional licenses. In approximately 30% cases, we recommend the client execute the rescue with their internal team or another external partner: the audit has intrinsic value. Storm and Hurricane guarantees are provided by contract.
