What the Freelancer needs to start the work
To get started, I’ll need a few details about your project:
A clear explanation of what you want the API integration to do
The platforms or services you want connected (Shopify, Amazon, Stripe, SaaS tools, etc.)
API documentation or developer access (if available)
Your website or web app login details (if required)
Any existing codebase or backend information
Features, workflows, or automation goals you want implemented
Timeline or deadline for the project
If you’re not fully sure about the technical setup yet, that’s fine — I can help you plan the best integration approach for your project.
