Hey there, we're glad that you're interested in building a Zeplin app—welcome aboard! 👋
Zeplin API provides you all the things you need to build a custom integration using the data in Zeplin. It lets you read all the resources including projects, screens, components, layers, assets, notes and so on. At this point, it only provides update or create functionality for limited set of resources and we plan to expand it more based on your feedback.
To use the Zeplin API for creating a custom integration, you either need to create a personal access token or a Zeplin app. You can create them from the web app under Developer tab in your profile page.
For any questions or suggestions, feel free to ping us at [email protected].
