# Authorization Method Codes

> Reference for the authorizationMethod values on transaction webhooks, mapping each code to what it represents.

The `authorizationMethod` field on [transaction webhooks](/docs/transaction) carries the **description string** from the table below, not the numeric code. The values come from the card network's point-of-service condition code (ISO 8583 DE25); the table maps each underlying code to the string you receive. Treat the field as an open-ended string: a value outside this table can appear if the network sends an unexpected code.

| Code | Description                                                                                                                                                                                              |
