Connector planning is the work of defining source authority, data contracts, mappings, transport expectations, failure handling, and ownership before implementation scope is agreed.
Start with source authority
Before discussing APIs or webhooks, decide which system owns each product-data domain. A connector cannot resolve unclear ownership by itself.
Define the data contract
Agree on identifiers, object boundaries, mappings, required fields and state transitions. This reduces ambiguity before implementation begins.
Separate data mapping from transport
Field mapping answers how information relates. Transport answers how information moves. Keeping those concerns separate makes the implementation easier to reason about.
Plan for failure
Ask where errors are recorded, who owns retry or correction decisions, and how operators discover that work needs attention. A connector without observable failure context creates operational debt.
Consider authentication and limits
Confirm which authentication methods, rate limits, retry behavior, and webhook events are supported for your account before implementation.
Define success before build
A useful connector plan states what data must move, which outcomes must be visible and how the team will verify that the integration behaves correctly in normal and failure scenarios.
Keep the product record, quality findings, ownership, and next commerce-preparation step in the same operating conversation.
