How does it work?
Open API conformance certification operates by giving you access to all the relevant test kits and resources to allow self-assessment and testing before applying for certification. This ensures you can optimize the efficiencies and costs associated with building and implementing the Open APIs while simultaneously preparing for certification.
If you have started implementing TM Forum Open APIs, here are the simple steps to completing self-assessments in order to gain formal certification:
- Contact us to set up the scope of your conformance certification
- Access the Open APIs CTK specification(s) from the Open API Table
- Follow the instructions for self-assessment of your conformance
- Run the CTK script against your API(s)
- Contact us to report your results for review and validation
To see the certification reports for each API visit thecertifications awarded table.
