Build the payout journey around reliable Shopify events

Identify evidence, state, and ownership

List the order events the program needs, when they become reliable, which system receives them, and who owns the resulting decision. A named handoff is more useful than an assumption that every event means the same thing.

• Source event
• Relevant fields
• Decision timing
• Exception owner
• Program record

Treat updates as part of the journey

Orders can change after checkout. The workflow needs an agreed response to edits, cancellations, returns, and delayed updates so recipients receive communication that matches the current decision state.

Keep the integration boundary narrow

Use only the Shopify data required for the approved purpose, keep access scoped, and avoid copying sensitive information into systems that do not need it. Card and identity data should remain with the authorized services responsible for them.
