Mitigate fraud-trigger patterns in agent-initiated transactions

Steps

1. Declare the automated nature of the transaction explicitly where the PSP or merchant supports it: Stripe's PaymentIntent accepts a payment_method_options field where you can supply relevant context; some payment flows accept a 'customer present: false' or equivalent machine-initiated flag.
2. Maintain consistent metadata across all agent-initiated charges from the same principal: customer ID, billing address, and user-agent string should not change per-transaction; erratic metadata is a primary fraud signal.
3. Avoid behavioral patterns that resemble card testing: do not attempt multiple small charges across many merchants in rapid succession; introduce natural spacing between purchases if the agent is processing a queue.
4. Pre-register the agent's spending pattern with your PSP account team if volume is significant — an anomaly alert on the PSP side for a pattern you know is legitimate can be suppressed proactively.
5. If a transaction is declined with a fraud-type code (do-not-honor, generic decline, card flagged), do not retry automatically; surface to the human and initiate a PSP dispute review process instead.
6. Log the full decline code and PSP response for every failed transaction; patterns in decline codes (repeated do-not-honor across different merchants) indicate a card-level flag that requires human intervention with the issuing bank.
