Hi OpenAI developers! A little background, I am a new developer interested in trying to incorporate OpenAI’s API into a small personal project. However, this will be my first time using an API testing tool. I have referred to other sources, but wish to expand my horizons and exposure to more API tools before really settling for one. The few API testing tools that I have been recommended and tried myself are: 1. Postman 2. Apidog 3. Insomnia The three tools listed above have nice user interfaces to begin with. However, are there any other great API testing tools that I should try? I am open to any tool, regardless of how big or small, old or new they may be. ---

Not sure about testing tools, but this will help with OpenAI API/Assistants: I created this custom gpt because the rest sucked and wouldn’t give me any useful code. > **[ChatGPT](https://chatgpt.com/g/g-zPTrliKgZ-assistants-api-ultimate-coding-guide)** > > A conversational AI system that listens, learns, and challenges
