PromptPay route diaryRecord the observed merchant path, not the reputation of the rail
Begin the Thailand payment diary at the exact advertisement and device used for the test. Record the landing version, amount and currency shown, customer eligibility, methods presented by the configured merchant, any PromptPay choice actually visible, authentication or application handoff, return URL, confirmation, failure state, refund instruction, and identifiers recovered after the redirect. The Bank of Thailand reference explains infrastructure context but cannot complete this diary for an advertiser. Preserve screenshots or redacted event references with their dates. If the route changes across devices or customer conditions, keep separate diary entries instead of presenting one successful rehearsal as universal checkout availability.
Thai copy inspectionTrace meaning through errors, assistance, and confirmation
A Thailand communication inspection should look beyond the headline. Assign a lane identifier, then compare product name, benefit, price explanation, qualification, navigation, field labels, validation errors, payment directions, consent wording, customer assistance, and the final confirmation. Record who reviewed the Thai meaning and which operating team can answer follow-up questions in that context. Do not infer a nationwide language preference and do not describe translation as a targeting control. The useful result is narrower: the advertiser knows which supported route carries the same promise, which wording caused abandonment or confusion, and which lane must be excluded until its after-click experience is repaired.
OCPB scope memoSeparate registration research from campaign performance
For the exact Thailand selling model, keep a short scope memo that identifies the legal entity, transaction type, sales process, customer relationship, and the qualified reviewer responsible for deciding whether OCPB Direct material is relevant. Attach any lookup or registration evidence without describing a listing as an endorsement. Store this memo outside the source-quality scorecard. A registration question and an advertising-delivery question require different evidence, owners, and remedies. If the business model changes, the memo expires even when the traffic sources remain the same. If source behaviour changes, investigate the supplier cell without implying that the official business register has validated that traffic.
PDPA observability mapShow where a valid data choice removes certainty
Build the Thailand observability map as a sequence from ad request to accepted backend outcome. Mark each campaign identifier, storage action, pixel, analytics event, payment handoff, and server record, then note the reviewed processing condition and what remains visible under each valid user choice. Use the Personal Data Protection Committee platform as a primary review entry point and obtain offer-specific advice. Where a permissible state removes a link, assign the result to an explicit unattributed category with documented limits. Do not recreate the missing source by proportional allocation unless a separately approved model states that inference and its uncertainty.
BOT context challengeRequire a campaign observation for every aggregate inference
When a Bank of Thailand payment indicator appears in a planning note, add a challenge row asking what the aggregate series actually measures, which period it covers, and why it was consulted. Then list the merchant facts it cannot establish, including live method presentation, eligible customers, successful authentication, source mix, acceptance cost, and future conversion probability. Pair every proposed operational action with an observed campaign result rather than the national indicator. This preserves the official statistic as dated context while preventing it from becoming an unsupported demand forecast. The review remains reproducible because another operator can see which decision came from the live Thailand cell and which statement came only from background research.
