FAQ
Common questions about custom ChatGPT App development.
Do you build the full ChatGPT App?
Yes. We handle product logic, conversation design, knowledge base structure, API planning, development, testing, submission preparation, and first-month support.
Can the first version launch without full APIs?
Yes. If some APIs are not ready, the MVP can start with static or semi-static catalog data and checkout links. Deeper account, top-up, wallet, or billing integrations can be added later.
Can purchase flow stay on our website?
Yes. The app can recommend, compare, explain, and guide users, then hand them off to your checkout, landing pages, login pages, support pages, or installation guides.
Do you support OpenAI submission?
Yes. We prepare app configuration, description, user-facing wording, safety and payment-flow clarity, and support required revisions. Final approval and timing depend on OpenAI's review process.
What materials do we need to provide?
We need product information, catalog data, website links, API documentation or technical contacts, policies, brand tone, test accounts, and support content.
What happens after launch?
We provide first-month support for bug fixes, scenario testing, prompt and logic adjustments, basic technical support, and small corrections based on user feedback.
