If there are no SDKs provided for your programming language, please refer to Custom Integration on how to set up your own integration.
Do not reuse the example code challenge and code verifier provided in the API examples, as this would expose your API requests to PKCE guessing attacks by malicious users. Refer to the example code under the SDKs section on how to generate valid
