ActiveCampaign API Connection For Custom App

I need to create an app for ActiveCampaign's AppStudio (structured around REST, HTTP, and JSON), based on my API (JSON RPC), replicating the same functionalities from my Zapier app for both the trigger and action steps. Trigger Step: - Users should make the connection using an Account ID and Account Secret (only once). The user should be able to save and name this preferece. - Triggers when new content is created (or errors). A webhook is given to the user. Action Step: - Users should make the connection using an Account ID and Account Secret (only once). The user should be able to save and name this preferece. - Based on the account data, a list of templates from the user would be displayed. API Method provided for this. The user needs to select one template. - Based on the selected template, a list of available dynamic fields will be displayed. Same API Method as the previous stage. - User can add personalization tags and/type content from the data source to create new content from my app with all the available options from my app and dynamic/conditional fields including title, description, custom metadata (structured data/dictionary), dynamic fields for the content, 1 field for logo, 1 field for banner, a set of fields depending on the type of call-to-action chosen. This is normally done through one API method. - Testing results Please note: - JSON RPC API - Details on the current Zapier app and current API will be provided when requested. - Some details will be seen as go over the app together. To be considered for this project, please start your response with a question regarding the project. Thanks!
