Steps for completing your project
After purchasing the project, send requirements so Rahim can start the project.
Delivery time starts when Rahim receives requirements from you.
Rahim works on your project following the steps below.
Revisions may occur after the delivery date.
App Scoping & Architecture
I review your app idea, define the required GHL API scopes, OAuth flow, UI requirements, and third-party integrations. I share a technical scope document for your approval before coding starts.
OAuth & App Setup
I set up the GHL developer app, configure OAuth 2.0 install flow, register webhooks, and establish the secure backend that handles GHL token management and sub-account scoping.
