Search the log for the transaction in question. The acquirer's response is the entry tagged `content = AuthorisationResponse`. It contains several parameters; **`authorisationResult`** holds the exact result of the authorisation attempt as a numeric code. ### How to read the codes The codes are grouped in ranges, so the first digit already tells you what happened: | Range | Meaning | | ----------- | ------------------------------------------------------------------------- | | `0`–`99` | Transaction approved — the payment went through, possibly with a remark. | | `100`–`199` | Transaction declined — the payment was refused. | | `200`–`299` | Transaction referral — the acquirer requires a manual authorisation step. | | `300`–`399` | Capture card — the acquirer instructs the terminal to retain the card. | The **Environment** column indicates whether a code applies only to e-commerce transactions, only to card-present (terminal) transactions, or to both. `RFU` means "reserved for future use". ### Response codes | Code | Meaning | Environment | | ---- | ------------------------------------------------------------------------------------------------------------- | ------------------- | | 0 | Transaction approved | | | 1 | Transaction approved -
