Certified Professional for Software Architecture – Advanced Level (CPSA®)
The CPSA®-Advanced Level Module API – iSAQB® Training Course in Application Programming Interfaces
Application Programming Interfaces
APIs as technical interfaces, organizational interfaces, and business-oriented building blocks.
How do APIs create value in software development and business strategy?
APIs enable the use of digital services through programmable interfaces and have grown significantly in importance over the past 20 years. From a software architecture perspective, APIs are valuable for both producers and consumers as they enhance reusability and simplify integration. More services are now accessible via APIs, allowing consumers to focus on core tasks while outsourcing others.
This module examines APIs as technical interfaces for communication, organizational tools for reducing interdependencies, and business assets for faster service development. It focuses on network-based APIs and also covers strategic aspects such as value creation and team collaboration, offering a broader perspective beyond just technical considerations.

Frequently Asked Questions
Is the iSAQB responsible for the quality of its training providers’ CPSA trainings?
The iSAQB operates an elaborate quality assurance system with regard to its training providers, CPSA trainings, and trainers. Our aim is to ensure a consistently high training standard for all CPSA training courses worldwide. However, despite extensive accreditation processes, the iSAQB assumes no liability for the quality of trainings provided by its accredited training partners. Furthermore, the iSAQB assumes no liability for the results of CPSA examinations.
How is CPSA program different from TOGAF certification?
Alongside the TOGAF training, the CPSA program rates highly in companies internationally. Compared to the TOGAF training, the CPSA program generally places more emphasis on the practical implementation of IT systems.
I have lost my certificate. Can it be reissued?
If your certificate has been lost, you can contact the certification body that took your exam or the iSAQB. Generally, you can request a copy of your certificate within 10 years after the date of the exam.
Is it possible to attend Advanced Level training courses without an existing CPSA Foundation Level certification and earn credit points for it?
Software architects who do not yet have a Foundation Level certification can also participate in the Advanced Level training courses. Successful participation in the Advanced Level courses earns credit points, which are required for a possible Advanced Level exam. However, a prerequisite for applying for an Advanced Level exam is always a successfully passed Foundation Level exam.
May I call myself “Software Architect” after passing the exam?
The CPSA certification is not a vocational qualification, but a proof of knowledge in the field of software architecture. The iSAQB is not entitled to award vocational qualifications, so we propose you call yourself “Certified Professional for Software Architecture by iSAQB” after passing the exam.
In Germany it is unclear if it is legally allowed to call oneself “Software Architect”. We recommend you inform yourself about the laws regarding the vocational qualifications in your country.
What does the Advanced Level curriculum include?
For the purpose of CPSA-A training, the iSAQB has defined the three following areas of competence:
Methodical competence: a systematic approach to architectural tasks, regardless of the technologies used
Technological competence: knowledge and implementation of technology solutions used in design tasks
Communicative competence: communication, presentation, argumentation, and moderation skills as well as the ability to cooperate productively with different stakeholders
Which requirements must I fulfill to access Advanced Level certification?
Successful training and certification at CPSA‑F level (Certified Professional for Software Architecture, Foundation Level).
A minimum of three years full-time professional experience in the IT industry, including the involvement in the design and development of at least two different IT systems. Exceptions can be granted upon application (for instance involvement in open source projects).
Training and further education within the scope of iSAQB Advanced Level trainings of at least 70 credit points. All three areas of competence must be covered with at least 10 credit points each.
Successful completion of the CPSA‑A certification task, including an interview with two independent examiners appointed by the iSAQB.
Who may offer and conduct CPSA-Advanced Level training?
Trainings at CPSA-Advanced Level may only be offered and conducted by training providers accredited by the iSAQB. Accredited training providers have proven the high quality of their CPSA training offers and are committed to the iSAQB accreditation conditions.
Are participation certificates for Advanced Level training courses also issued if a training course has to be cancelled through no fault of one’s own, or if the participation is delayed?
For Advanced Level training courses, participation certificates with the designated credit points can only be issued if a participant has attended at least 75% of the training. If less than 75% have been completed, the intended credit points may not be awarded. It is necessary to repeat the entire training or to make up for the missing part in order to earn the credit points. In any case, this regulation also applies to reasons that are not the fault of the participant (e.g. illness, accidents, traffic jams, etc.).
Are credit points awarded for participation in online training courses at Advanced Level?
For online training courses at Advanced Level you will receive an official iSAQB participation certificate with the respective credit points.
