    'items' => [
        [
            'description' => 'Web Development Services',

​
Community SDKs

Community SDKs are maintained by the community and may not always be up to date with the latest API changes. We recommend checking their documentation and testing thoroughly before using in production.
If you’ve built an SDK for the Contazen API, please contact us to have it listed here.

​
Building Your Own SDK

If an SDK doesn’t exist for your language, you can build your own using our OpenAPI specification. Many languages have tools to generate client libraries from OpenAPI specs:

​
Example: Generating a TypeScript Client

npm install @openapitools/openapi-generator-cli -g

openapi-generator-cli generate \
  -i https://api.contazen.ro/openapi.yaml \
  -g typescript-axios \
  -o ./contazen-sdk
